Global Star Party 138

Transcript:

Say howdy to everybody that's going to be tuning in
here how you spell HW
Dy so if you're watching right now you are tuning in to the 138th Global star
party with the theme of
impacts David have you seen this visualization that's on the screen right
now no I have not Shoemaker leavey nine fragments hitting
Jupiter oh actually I might have seen it back then but uh not
recently I don't know when this was created it looks pretty
detailed we got Jim Mosley on from R Rancho and Mike weasner
from veale Arizona and John Ray not sure where you are actually Mike is from
Oracle Arizona oh that's right that's right you're from Vil I'm from
Vale we all wish we were from Veil
actually
okay almost time to
start
is
[Music]
this is an image of something called m87 m stands for Messier and Messier was
an astronomer who was very interested in finding comets but he didn't want to find Duds he didn't want to find false
alarms this is one of them and you can see why if you were looking at something like that in a small telescope you might think it was a comet and if we keep
drilling down into why m87 is such a fascinating Galaxy it is an elliptical galaxy and it's been known for quite a
long time that there was this little thing of brightness that was spewing away from it and now we know that that's
actually a jet of material when Hubble was launched we had really good clues that galaxies probably
had black holes at their centers so m87 does indeed have a very massive super
massive black hole at its core on the two to three billion times solar mass level and that's a very massive super
massive black hole but it's also active why so why are galaxies active not all
galaxies are active just a few percent are active at any given time are they turning on and then turning off that's
an idea you know maybe there's some mechanical um physics going on at the center of these galaxies where the black
hole has an accretion disc and that material is getting spun up so quickly we know there's very high magnetic
fields that you launch a jet and so this image is observational evidence that what we've been seeing for a while is
actually being launched by a jet connected to that super massive black hole at the center of
m87 what we're seeing here is one jet so we can assume that this material here
that's made up making up the bulk of m87 huge Stellar population is obscuring
the other jet in order to get a jet like that you need a magnetic field to accelerate particles and you also need a
source of charged particles so that means that you need near the core of that Galaxy a
disc of material and that that disc of material needs to be spewing in towards the black hole it's got a huge amount of
gravity it's going to suck stuff in and when it gets close enough it starts to accelerate those particles to ever
increasing rates and then spew them out along magnetic field lines we've got lots of particles and they are being
accelerated at nearly the speed of light actual connection between having a
super massive black hole and accretion disc and launching a jet is still one of the mysteries of high energy
astrophysics how does that get launched what is the actual physics between the black hole the disc and that

well hello everyone this is Scott Roberts from explore scientific and the explore Alliance and this is the 138th
Global star party uh my co-host David Levy is with me and um let me bring
David on there we go we are sharing sharing
the stage hello everybody yeah and we got uh something special
planned for them uh today David and uh uh you asked me not to show you uh the
um the uh video that I put together but um I was able to grab some really nice
video of Jean Shoemaker and uh I'll let the story play but um uh you know you
knew Jean I never got to meet him I I met Carolyn uh and um uh in some ways I
felt I feel like I did you know sort of know him through all the stories and uh
you know the documentary uh information I've been looking at and um all the rest of it
just seems like just a super down toe guy and uh probably had a great sense of
humor and um you know tell us more
David well this is this is really uh a time for missing people I Miss Jean and
I miss caroan but this this week is particularly difficult because this
coming Sunday we will be having the unveiling of Wendy's Tombstone and boy do I really miss her
so for my poetic quotations tonight I have two the first one is called gone
from my site it's credited to Henry van djk although he did not write it and uh
then following that I will be doing uh with much voice as I can a rewrite of
the first of one of the verses of Leonard on Hallelujah so here goes I am standing
upon the seashore a ship at my side spreads her white sails to the moving
Breeze and starts for the blue ocean she is an object ofy Beauty and strength I
stand and watch her until at length she hangs like a speck of White Cloud just where the Sea and the sky come to mingle
with each other and then someone at my side says there she is gone gone where
Gone From My Sight that is all she is just as large in Mast Hull and Spar as
she was when she left my side and she is just as able to Bear the load of living
Freight to her destined Port her diminished size is in me not in her and
just at the moment when someone at my side says there she is gone there are otherwise watching her coming and other
voices ready to take up the Glad shout here she
comes it's time to go Outdoors tonight the sky is dark some stars are bright
the Milky Way shines overhead now see uh a comet rises in the East with them to
Strife it brings us peace and calls us to a cosmic
hallelu hallelu and now back to you Scotty okay all right thank
you um I want to talk little bit uh
about the the impression that um that I got you know I
was able to of course uh relive some of the experience of comic Shoemaker ly9
that is something of course you're internationally famous for and and will
always be down in history books for but you know this wasn't just a discovery
this when I see and I was trying to describe it to Dave ier and some of the
people who were on right now some of the presenters that are on
uh I there is now this Arch ranging all the way
from you know the first thoughts that uh that meteors had impacted the Earth
to uh Jean shoe makers research you know
verifying um that indeed this has happened but up up until like the late
1950s it was still there were still people in the camp that uh maybe these
things are volcanic you know and and these these are not impact graters um
during the time that uh Jean Shoemaker was studying uh baringer meteor crater
I'm not sure how many other suspected craters there were but I I would guess
there's not very many there weren't any at the time any okay so today there's
something like 190 okay um but uh you know most of it's been most of the
others I'm sure that the that the Earth was creatored like the Moon is you know uh and um you know so much of that has
been erased by uh you know climate and oceans and all the rest of that but
um the thing that I was left with was uh you know here we have uh this this
warning that uh that you know Earth does get hit by comets and
asteroids and and that that uh that warning um at the time and we didn't
have the technology we didn't have uh or no had worked out all the details of
what we would do if we were uh you know about to be hit by uh an asteroid or a
comet uh there was just absolutely nothing and then came along the dart Mission which was successful and um so
to me all of these people um including yourself David uh uh you know you have
um you have made a a very significant contribution
to possibly saving humanity and um and that hit me like a ton of bricks today
you know I know David we're friends if you've gone to Star parties and you met David it's easy to make friends with him
uh and he's very uh he's humble about this he doesn't sit around and brag about it okay um sit around and brag I
can sit around and brag brag brag brag but I think that you were faded I think
you and the and the shoemakers were faded to find this Comet and um and you
know and the uh the dart mission team I just absolute genius to be able to move
an asteroid uh to deflect it successfully you know so uh I imagine at one point we'll have
an armada of spacecraft at the ready in case any uh you know dangerous uh things
start flying our way but uh uh but I just wanted to say that and uh you know
and I I'll be the first to say that uh as someone occupying a a place on this
planet and um that uh I really appreciate and thank you for the hard
work that you've done because you've devoted your life to it and um uh you
know this is it's not an easy thing so well could you let me do my little SP
about impacts at this point please do okay thank you uh thanks Scotty
um uh actually the first time that I saw Shoemaker
le9 was not in J in March of 1993 but in September of to
1960 I was 12 years old and uh my uncle had bought me a bar
miter present of a small telescope a skyscope three and a half inch telescope on September the 1st
1960 we set it up and pointed it towards the only thing in the sky that was
really bright and worth looking at that night I had no idea what it was but when I looked at it I right away
decided I was going to send the telescope back because telescope was lousy all I saw was a donut with a hole
in the the middle of it and out to focus something and I thought well there's
something wrong with this telescope and then I kind of bumped the eyepiece a little bit with my finger and uh the dut
got a little bit smaller and the hole in the middle of it got a wee bit
smaller and then so then I thought uhuh maybe maybe I need to know the
telescopes need to be focused so what I did was I uh continued
moving the eyepiece down the hole eventually disappeared completely and the image focused into magnificent view
of Jupiter Galileo himself would have felt no greater thrill than I did that night at my first view of the Jupiter
his four bright Galilean moons and some of the marks on the planet there was
also comu maker levy9 it had just gotten itself into an orbit around
Jupiter or may have been in an orbit around some time and obviously of course
I didn't see it that night uh nobody saw it that night certainly not with a 3inch telescope
because the comet was way too small way too faint in
1993 uh we were we were observing and there was a cloudy cloudy
night and uh uh we were um taking a
picture and uh really it came out okay but then there were clouds that came
by and uh we had to stop we went outside and I looked over at the southwest and I
said hey guys it's clearing up a little bit and Gan just started to laugh he said that's our David because I was
called David at the time that's our David always with the optimism but David
I'm going to tell you something every time we slap a film into of that telescope it costs
$8 and I said Well jean that's not too bad $8 toh take a r take to put a film into
the telescope and sheene wiel around looked at me and said that's eight American dollars David not that Canadian
funny money you guys play with anyway so
we um but then Carolyn looked up and said you know Jean it is clearing up a
little bit and Jean looked and I looked and Carolyn looked and Jean said let's
do it and the very next picture we took was the uh confirmation
image of the two that uh show comeet Shoemaker leaving
n and uh the next a couple of days later Carolyn is scanning the
images and she uh she's looking at at the uh at the images
and uh uh I was working on a book on comets at the
time of all things and uh Jean was reading Time Magazine of all things
Carolyn was the only one of us doing any work and so suddenly she stopped looking
through her stereo microscope and she looked up and she said I don't know what I have but it looks like a squashed
Comet and uh Dean wanted to look at it so he got second dibs on looking at it
and uh Carolyn went over near me and I said you are joking aren't you Carolyn
and she looked at me and she said no I'm not so I got to see that beautiful
fantastic image of a comet that was broken apart it looked exactly as she
described it like a squashed comment and we sent the uh the notice to
Brian Mar about an hour later with the rough position and uh we
eventually later were able to get a more exact position and while we were doing
that I called my friend Jim Scotty who was at the uh kit peek at the 36 inch
telescope at kit Peak at the time and I told him what we had and he said well I
don't know I'm a little bit busy now but if I get a chance I'll try to to take a
look at it while we were waiting we went and we did an accurate measurement of
the center of the um of the train of that kment when we got back to the
18inch I called Jim Scotty to see if he had done anything yet he picked up the
phone and he goes and I said Jim are you okay and he
said and I said Jim do we have a comet he said
the sound you just heard is me trying to pick my jaw off the
floor boy do you guys ever have a comment and uh the message that he the
confirmation message he sent to Brian Marsden was it expressed that it was the
most unusual comment he had ever seen two months later on May 22nd
1993 we were back at the uh at the telescope Hope by this time we're
getting beautiful clear nights and everything is fine and Brian had told me that he said
you better watch your email because I might have a pretty interesting uh circular coming out in a
few days that you're going to be interested in but I can't tell you right away what it is so I kind of forgot
about it and then I'm uh Carolyn scanning a scan that will result in the
disc discovery of yet another Comet that day and uh I'm reading my email and the
circular comes out and uh it announced that the the Delta J the
distance between the comet and Jupiter was getting very very
small and uh it turned out that at the bottom the Delta J was actually less
than Jupiter's radius and
uh then there was a second circular in which Brian actually said that there was
going to be a that the comet was actually going to collide with Jupiter probably beginning on the 16th of July
of 1994 so we had quite a bit of time to scan on it so I interrupted Carolyn and
I said Carolyn just got an email a message from Brian that our comet is
going to collide with two and Carolyn looked at me and said we're going to lose our Comet I don't know
that I like that and all of a sudden Jean who's loading film in the dark room
started yelling at us he said don't lose it don't do anything just wait I got to
take a look at this and uh so you could hear him banging around as he's protecting film
and getting things all protected and he rushes out and he sits down at at my
computer my laptop and he looks at the email and he says to himself and to us I
can't believe this in my lifetime we are going to see a comet colliding with
Jupiter and we're going to see it in my lifetime I just can't believe this he
was like a little kid with such excitement and we had a lot of
interesting things going on in the next year as we prepared for the impacts
and uh as I bring this to the end of my
little my little presentation right now I just wanted to say
that that we've learned a lot about impact since 1994 and uh most of the people who were
active then are either no longer living or are retired by now because that was
30 years ago and next year in 2024 I will be giving a number of
lectures talking a lot more about impacts and about the meaning of it and
about the goal but uh the main thing I want to say about
impacts is that when a comet collides with a planetary body it breaks apart
and it collides if the body is solid it will leave a very large impact crater if if
it is gaseous as Jupiter is it will just plow into the gas and then a big plume
will then exit the planet and uh be really very exciting
and that's what we saw with Jupiter in 1994 are we going to be hit by something
the answer is yes there is no question about it the question is when while we were getting ready tonight
one of us said Well it's it's not going to be millions of years it's not going to be millions of years maybe hundreds
maybe dozens maybe even thousands but certainly there is about a chance of one
in a thousand that in our lifetime we will actually see a commentary impact on
the earth we don't know that yet nothing's been detected that is going to collide
with the Earth but there is stuff out there comets and asteroids that are going to visit the Earth and that are
going to impact I know that's going to happen and I think that's why it is so important that we have this particular
subject on tonight's um on tonight's Global star
party and on that basis I'm GNA give it back to Scotty I have to leave for a few
minutes but I will be right back thank you thank you so
much well um uh I think that uh you know
the focus on um what we can do
uh with regard to um you know big impactors is uh you know we're just at
the infancy of all of that but I think that uh if you're listening out there you're watching a rerun of global star
party and you run into this uh that um you know you if if at all possible uh
when there's a a um a science issue uh that comes up uh in your in our Congress
and your your country's Congress whatever uh that you vote for it and um
and that you support science uh because we have some daunting problems out there
uh and uh you know the impact situation although extremely rare uh can happen
and um so you know if we can be ready for it let's get ready and so uh but I'm
going to turn this over to uh Jean Shoemaker and a younger David Levy um
with this uh program [Music]
here all the planets are going around in these nice uniform orbits and it's all running like clockwork and it is a very
peaceful tranquil place out there that's a
myth it's like being in a hail of bullets going by all the
time [Music]
they are bullets they're bullets out there in
[Music] space these things have hit the earth in
the past they will hit the Earth Earth in the
future it will produce a catastrophe that exceeds all other known natural disasters by a large measure before Jean
Shoemaker few people gave it much thought one of the most powerful forces
in the making of our planet and perhaps the deadliest Hazard we face if nature
hit a large metropolitan area like Los Angeles it would simply obliterate
all of Los Angeles and the surrounding region there would have been a cloud covering the entire planet within 2
hours and it would have lasted for year 3 2 1 come
on Jean Shoemaker geologist was looking for rocks not on the ground but in the
sky that night he and his team found something astounding a portent of another kind of big
bang Comet Shoemaker levy9 first appeared as a faint smudge in space it
grew into a blazing streak of Light by the time it smashed into Jupiter every major telescope in the
world was [Music] watching the impact Unleashed fiery
plumes large enough to incinerate the Earth and it raised a terrif fineing
question could it happen here the seminal event that really alerted
everyone to the to to Yes Virginia comets do hit planets was the Collision
of Shoemaker leing n into Jupiter and all the years I've observed I've never seen a comet like this I've
never seen anything like this there were at least five separate comets all together with his dust Wings on either
side and then the Tails going off to the north which later came to be called a String of Pearls there were many little
comets all lined up each one going on its own orbit uh but very closely
related orbits and it was clear that this had once been one Comet that had gotten too close to Jupiter and had been
torn apart in the gravity not long after discovering Comet
Shoemaker levy9 they learned the comet was on a course that would lead to its own violent end well I saidoh my gosh
and Carolyn stop and said what what I said are comets going to collide with Jupiter in 16 months from now I think
for the next half hour the three of us just stared at the announcement je was saying I don't believe it we're going to
see a collision in my lifetime on July the 16th the first
fragment of Shaker le9 crashed into Jupiter traveling at a speed of 100 and
40,000 mph it would be able to cross the United
States in a couple of seconds of that scet it tore into Jupiter really Jupiter
didn't know what hit it the explosion from the first fragment of Shoemaker
ling9 Rose over 2,000 miles above Jupiter's Cloud
tops and the few hours later another one hit the next another one hit Jupiter got
hit Bam Bam Bam at least 16 times over the course of 6
days but the most powerful impact was Yet to Come fragment G exploded into
Jupiter raising a fireball visible from
Earth it left a cloud larger than the earth and a cloud that lasted on Jupiter
for almost a year one of the questions that that we
all had when we were watching this enormous Damage Done to Jupiter was what
if it had been us Imagine One hirosima strength
bomb being exploded every second for several
[Music] years that is the energy released by
Shoemaker leaving on in his collisional [Music] tu
the magnitude of the impacts into Jupiter surprised and alarmed the scientific
community and one of the big discussions was how do we get rid of the giggle
Factor we go to Congress and we say a comet could hit the earth someday and everyone
laughs after Comet Shoemaker ling9 nobody was
laughing is my opportunity to to pay homage to the engineers and Technical experts flight planners on the mission
because they are setting the stage for what is our main act which as we know is the impact with dioros and there's no
better person to speak with me about our Target asteroid then Andy Chang who is
Dart investigation team lead Andy thanks so much for joining me thank you well
Dart is the double asteroid redirection test because we'll do this test to the
kinetic impactor at a double asteroid sort of you know represented by this model it's actually two asteroids that
are orbiting one another and dart will come and it will hit the moon the smaller asteroid of the
system to change the orbit of the moon around its primary the reason we want to
do it that way is that we can measure the change in the orbit we can measure the effect of the kinetic impactor using
groundbased telescopes what happens when you look at it from the earth is you see that the two objects move in front of
and behind each other and every time that happens in the telescope what you see is a dip in the amount of light
astronomers on the ground can time these dips very precisely to measure the
change in the orbit period when Dart hits the Moon the Moon that Dart hits
it's an orbit around a much bigger asteroid didos and so even though we can
make a 10-minute change in the orbit period of Doros we hardly move didos all
because it's just so much bigger just not able to move it very far interesting well you know what's also interesting
Andy is that I hear we have a lot of binary asteroid system that they're not very uncommon um but we want to choose
this one because it's going to be close enough and at the right time right for this mission to happen damos is close to
Earth that makes it easier to see with a telescope and to make the precise measurements that are needed and the
other great advantage of course is dios is not a threat to hit the earth it never get comes closer than about 3
million miles to Earth that was true before the dart impact it's also true after the dart impact we just cannot
Dart is just not big enough to be able to make an appreciable change in the orbit of dios around the Sun and this is
mindboggling to Me Andy but I heard you basically dreamt up this whole mission while in your basement now is that true
yes that was that was a winter morning in 2011 today it's it's it's it's really
it's really like the birth of my first child of course someone else is doing all the work and I'm doing all the
worrying and now we're so close within half an [Music]
hour
[Music]
[Music]
well that's uh that's a short 10minute uh um video but um I think it tells the
story pretty well and uh uh you know so it makes me want to study
um asteroids and comets even more than than uh than what I do so um and it's
wonderful to have uh David Levy here with us every Global star party uh to
kind of be our guide and um you know and to help us uh understand the the context
of of all of this stuff it's it's easy it's easy for to take it all for granted
um but uh you know what what these astronomers have done and uh these
researchers have done and what Congress did and all the rest of it is just
really amazing to me and so it's it's wonderful to have lived through this and
um you know there's more to see and there's more to explore there is more to explore and I'm
I want to tell you that as I was doing the Hanukah blessings just now with my grandson I was able to keep an eye on
the video of the movie I'm gonna watch it afterwards um but I'm back and
um uh it turns out I have not seen this movie before so I need to check all the things I said to make sure I still agree
with them but anyway I'm back great great
okay so also with us tonight is David AER and David Aker is
going to be talking about staris um we we've talked a lot about staris on the
global star parties uh they are preparing for the next one in Slovakia
and uh both David Levy and myself are supposed to be there with David ier so we're really excited about this and uh
you should you should seriously consider going you know if there was a bucket
list for astronomers to go uh to any event uh this should be on that list so
I'm going to turn this over to you David
um and here we go thanks God and I will share my screen and I will share the
right screen and I will start and first of all let me just say and I'll start a slideshow maybe too uh oh oh dear um my
thing is in the way here can I start it
here maybe yes there you are um okay and
you know it's amazing Scott let me just say very quickly uh you know that we're meeting these old friends um that you're
bringing back into the gsps here you know with Bart Bach and and again with
Jean and Carolyn you know it was through David um that I met them and and they were you know the kindest nicest people
and of course every time you were out in Flagstaff they were a major fixture whether it was you know seeing us a
number of times up on Mars Hill or of course over at USGS um you know they were sort of like
substitute parents you know uh back when you were in your 20s there so we miss
him a lot and it's great to see them but Switching gears um the starmist festival
is a unique thing this is opening image was taken by none other than a fellow named Scott Roberts this is where he and
a couple people surprised me last year um when I they found out that it was the
40th anniversary of me being at astronomy magazine um if you can believe
that so we had a little celebration there with an astronomer bottle there um
which was great fun but I'll talk in in some detail about the storus festival itself and how it got going it was
founded in 2007 the first Festival was held in 2011 in the Canary Islands um
and stars uh starma stands for stars and music and this happened in a sort of a
convoluted way because there's a famous astronomer who bailed out on his PhD
work in 1970 who was at tenar Reef in the canaries um and he went on much to
his family's disappointment at first to join a rock and roll band uh that's
Brian May and it worked out okay for him you know uh the band Queen um they did
all right you know within the span of a few years there but uh it was a
childhood hero of Brian's Patrick Moore the famous English television astronomy
presenter who really kind of you know scolded and admonished Brian to go back and finish his PhD which he did in 2008
and on a subject uh related to the um dust in the solar
system and one of the people at tenie at that time was uh the co-founder of
staris and the guy who really had it as an idea an astronomer there Garrick israelian and so the and he's also a
musician so the two of them got together and had this idea where we really want to have a festival that celebrates
astronomy and Science and music and the Arts as well so staris was born and we've had a
large number of Nobel prizes laurates and Astronaut explorers and scientists
from all sorts of fields as I'll mention here a brief survey most of these images
and things I'm going to talk about are from last year's staris uh which we had in
Armenia however next spring we will hold the seventh staris Festival in Bros
Slava which is just a hop skip and a jump from Vienna so really you can fly
even as you know Americans who think this is like going to the Moon it's it's pretty easy actually to get there you
can go to Vienna um and then take a half hour car ride over to where this is it's
pretty easy to get to it's going to be held May 12th through the 17th of next
uh year um we're about to turn the corner on and there'll be a little expanded range of dates because we're
going to do some special things I'll talk about here as well an astrophotography school as well that
will extend that date just a little bit here you can see star.com for the complete
information all about the festival there and it consists really of a number of
things last time uh in Armenia we had about 5,000 people I think all together
there um and it consists of a lot of scientific talks in all sorts of fields
workshops concerts as Brian likes to say you know you have to use both hemispheres of your brain um so there's
there concerts there's a a lot of music as and creativity and art as well as science tours of historic and cultural
sites they local and as I mentioned there's an astroimaging workshop and a star party the chief uh architect of
whom is none other than Scott Roberts so uh let me go on and talk a
little bit more about it past festivals has happened have happened in the Canary Islands in Norway in Switzerland and as
I said in Armenia um about 5,000 people were there in yavan uh the last time we
were there um and it's governed by a board of advisors that includes uh
Garrick and Brian Richard Dawkins the very famous that if you will the the uh
um great uh sort of evolutionary biologist of our time Emanuel sharpen
here who if we're fortunate enough uh she's a Nobel Prize winner she may extend our lives she's the one who won
the the Nobel Prize for the crisper Jean splicing technology Jane Goodall who's
the most famous primatologist of course on the planet Peter Gabriel he's a very famous claimed musician a great guy Jill
tarar of course the world's uh most famous seti researcher Tony Fidel who
you owe something to if you own an iPod or an iPhone because he invented them and then myself on the board as well hey
there's always got to be one Troublemaker in the in the group right um so the scale of staris is large but
it's really designed so that attendees can hear and access the personalities
relatively easily you can get up close you can talk to people we had more than 50 speakers in Armenia in different ways
and Scott will be there uh with me as well David Levy will be speaking this
coming uh time so we're very excited to have David there as well and uh this is a tiny tiny sample
of the planned speakers here because we'll have no doubt more than 50 speakers again um but they'll include
Brian Jane Goodall Kip Thorne the world's leading expert on black holes
Brian Green Tony Fidel myself Katherine heho who's a leading uh climate
scientist Jill Tarter Charlie Duke our pal Apollo 16 astronaut Chris Hadfield a
very well-known astronaut Explorer Michelle mayor who won the Nobel Prize
for the first discovery of a an exoplanet orbiting a sunlike star you
may remember in 1995 Adam Reese Lisa ceger Chris rapley Patrick Michelle
Garrett reesman Donna Strickland and Emmanuel these are all Nobel Prize winners or astronauts who I've mentioned
there but we'll have many many more speakers in addition to that what we have planned for in in Bros
Slava this time is focusing on the future of our home planet Earth uh life
on Earth the climate environment uh environmental cyber attacks the promise and danger of AI will be a theme
Technology Solutions and dangers we have a film that we've produced as well
that's written by yours truly and produced by Todd Miller who's the fellow
who created the Apollo 11 documentary that's spectacular that you might scene as well we'll be showing that film
uh as I mentioned many speakers we'll have a lot of rock and roll going on and other music as well um from Brian Rick
Wakeman who's another good close friend of the festival the great uh keyboardist
of rock history um from yes and other groups and other notable musicians as
well Michael bakit my colleague from astronomy magazine will be running the astroimaging school uh sharing technique
it's easier as many of you know than ever by far now to capture your own
images successfully of the Universe um and that's going to be a a probably a
three-day uh event I think that will precede uh the main starmus and Damen
Peach Chris Shore and Martin Ratcliffe will be with us uh there who were very well-known imagers and writers and
they'll be teaching us techniques Scott will put on a star party as well again for us as we did in
Armenia uh we'll be holding this uh at a castle that dates back to the Middle
Ages and actually its ruins date back to the Neolithic Age um but really the the
structures that are there that will be set up with telescopes from explore scientific and their Partners uh date
back to the 13th century so it's a spectacular place we will be to observe
the sky let me just run through a tiny sample of speakers and of things that
happened last year to give you a very small flavor of what it's like this is Garrick who founded the festival along
with Brian May and he's opening the festival here you can see last time we had a 50 years on Mars theme and so we
had an elaborate Martian stage uh going back to the first Mars Missions at
starish you never know who you'll end up sitting next to just a warning there um
this is a famous guitarist there in in in case you don't recognize him um and
you can run into lots and lots of people who are very interesting and very generous with their time and talking to
others about their work and about what they've done this is Kip Thorne who since we lost our good pal who is on our
board as well as Stephen Hawking hip is is alone now the in being
the world's expert on black holes so he will be there as well speaking again um
this is in Armenia we had exploration of of great history and culture around
yavan this is outside of the city Amber Fortress that goes back a thousand years
as well and we opened the festival with uh some musicians Derek sherinian is is
of Armenian ancestry and so he and his band opened the festival there with a
great first night show we also had another Armenian friend
musician ton um lighting up the crowd there with a show and a choir along with
them we had a number of people joined me for a press conference to open uh the
event and we had about 50 press from around the world covering us so it it gets covered as a sort of a big deal
this event uh and uh Rick Wakeman then uh played piano along with the Armenian
national Orchestra we had the entire National Orchestra there with us to open
the first main event on the main night when all 5,000 people were there in this
Auditorium a a stadium really we also honor our dear departed
colleague Stephen Hawking who was on our board with us um giving out medals for
Science popularization and and this time we we gave one to Brian we gave one to
Diane Akerman who's written a lot about nature and about the environment for the New York Times and other Publications
the NASA Communications office um and Jane Goodall who has joined our board as
well now and we've given them to a wide range of science communicators in the
past this is Jane delivering Her speech remotely uh accepting the award and of
course you must know of her work with chimpanzees that has led to a lot of the understanding of what we know of primate
now in this world being our closest relatives to Homo sapiens uh Jane will
be there in person with us this coming spring uh so that'll be a highlight for us we had uh bumblefoot of the sons of
Apollo rock band there uh soloing right in front of us and and that's Garrick
and Brian with me shooting the image next to them here um putting on a little show for the guitarist here so there's
there's create ity and there's art that gets interspersed with all of
the science the pure science and even you even have some troublemakers showing
up early to try to set things up here and cause problems um so the cautionary
word there uh Michael bakit our senior editor at astronomy now just recently
retired uh along with myself MC some of the sessions here's Michael sort of
taking away the first big day and there many speakers on a fairly Elite uh level
here a pal of ours who's at the max plunk Institute in in tubingen uh
burnhard skoloff he'll be back again this year as well and he he's a sort of a mild-mannered guy he was at the
astrophoto school just sort of saying well you know what kind of exposure should I do in on this kind of thing we
didn't really know who this guy was and it turns out he's one of the world's leading experts on artificial
intelligence so he he'll be speaking about that and where things are going with AI once
again again there are tours of interesting things historically and culturally that happen at every starus
trip and and this is arabon Fortress which is right in this smack dab in the center of hovan essentially where the
city was founded in in 782 BC so we looked at the ruins and had a good time
a fantastic and huge Museum uh exist there at this archaeological site as
well just a sampling of many many many speakers again this is Lou fredman very
well-known planetary scientist of the planetary Society who founded that group
along with Carl Sean and a couple of other colleagues many years ago talking about the history of Martian
exploration Michelle mayor I mentioned before he's uh the fellow who uh the
Nobel Prize and discovered the first exoplanet orbiting a sunlike star 51
pegasi back in 1995 and sort of broke open the modern era of exoplanetary
Discovery he'll be back again as well he's a good pal of ours the director of the Carl Sean
Institute at Cornell is Lisa ceger who is a hoot just absolutely hysterical
she's Austrian by birth but is of course in Ithaca now I got introduced to her in
Armenia I'd sort of seen her around for some years before and she comes up to our banquet table where a number of us
were sitting and said hey you got to move out of here this is our table you
know and and I said well what do you what do you what do you what do you mean you know went over I talked to Garrick I
you know what's going on here who is it and for so for half an hour she played an elaborate gag on me and then
introduced herself and we ended up having great times together so so you know you never know what you're going to
get scientists can have a hell of a sense of humor too believe it or not um this was really a cool moment
fairly early in the festival we had not only the Armenian national Orchestra there but the Children's Choir of tush
um one of the elite uh young singing groups of the country of Armenia came in
and we did the same trick that that Queen does in their concerts by sinking Freddy on film to do some singing with
live singing that goes on which is really works incredibly well uh the timing and the technology of it and I'll
tell you looking around they did a medley of Queen songs and looking around when the kids were singing uh We Are the
Champions with f there were people who were tearing up in the audience seeing Freddy and these young children singing
These Queen songs it was really something to see
and then we had the real guy from Queen there on on the right Brian along with
an old pal in the center there you you might remember back in the day the rock group called
10cc this guy's the founder of that group and did lots of other writing of songs for other people as well he's a
very nice guy Graham Gman um and they had uh I'm I'm not in love was their
great greatest hit I think but he also wrote a bunch bunch of songs for other people he wrote for your love the the
great uh another great 60s hit and so they banged out um with our our pal
bumblefoot um a bunch of songs the three of them together that went really well
this is kind of a speakers stand up who are there on the first night and and get
a group shot there so you can see that there's quite a collection there of of folks from planetary science and
cosmology and and pure as ason omy and biology and chemistry and zoology and
other fields as well it's really all the Sciences now that that staras focuses on
this is always a highlight I think we've done this three times now at staras uh Chris Hadfield is a very well-known
celebrated astronaut Canadian he's the nicest guy in the world he really is and
he became very famous because he sang in real time on the space station you might
remember this he sang David Bowie's great hit space odity on the space
station in a live broadcast so he does that at each stas for us now and and
that really gets people as well and he's Canadian and he's Canadian he's a hell
of a nice guy he really is he's very very smart guy of course and and really
gracious and very very kind uh here is a shot with I think there's a Scott and a
Dave and and a and a Holly bage and a Michael bage in there this was our
astrophotography school which we did for the first time in Armenia we're going to do it again now in Slovakia um and it
went really well and and it's something that people got a really big kick out of um and then we had a star party and
we didn't have a star party just anywhere uh Scott you might want to chime in on this as well um this was
Garney Temple a 1900 yearold Greco Roman Temple we had as the backdrop for
Scott's telescopes yeah yeah it was a great backdrop and it it was lit up um
uh quite a bit as you can see here and the and the lights stayed on uh during the star party
but um you would have been amazed at how many deep Sky objects we actually got
there and you know as you as you kind of moved in towards the eyepiece the guy
standing right behind you was an AP astronaut and uh you know um you just an
amazing group of people to be with and uh experiencing this night there was
live music um there was uh uh free uh
drinks um free beer um and uh it was uh
it was a very very special night unlike any Star party I've ever attended I
think this Fusion of music and looking at the stars live music uh really um
leaves an impression upon you I will never forget the star party and uh
really felt honored to be there um there was also a great meal before we uh uh
started at this uh event and um you know so by the end of it I was pretty spent
but uh really loved the experience of it and this was this was kind of the more
or less uh VIP event uh which you could you can get tickets for if you go to
staras um but there's also a uh fre star party that we gave for the public uh I
need to share some of my images with you David but we were absolutely crushed with people uh you you throw out a
number of 5,000 people there must have been tens of thousands of people coming
through the star party and away at one point th this was right downtown in one
of the squares in y it was flooded with people yeah and there was also a live
band and uh you know the people there were so uh hungry uh for to learn more
about science to look through a telescope to experience uh uh the
different technologies that were showcased at staris uh was really
amazing you know it's pretty wild when you're looking at the moon in a telescope and you take your eye from the
eyepiece look over and talk to Charlie Duke about what it was like when he walked on the moon you know that doesn't
happen every day you know no that does not happen every day but uh it's uh you
know these people are so warm and friendly and sharing and giving as as you described uh uh David and I frankly
I didn't expect that you know I didn't expect it I I but after a while you you
know you understood that uh uh they were just as interested in in what you had to
say is is what you had you know the interest in them so it's totally cool
when I tell people you got to go you got to go there's really nothing else like
it um as an event and this time as I mentioned going to have our star party
here at Devon Castle um which goes back to the the 13th century the the stone
walls that we see here and predecessors uh much farther than that back in time
um but but this is what's left of it and it's a huge area so we'll have plenty of
room for telescopes here I think Scott yeah yeah you know and being in a place like this it's ancient and it feels
sacred okay it feels sacred secret I don't know how else to say this okay but
you're you know you're looking up at the sky you're you're almost uh inebriated
not not from alcohol but from from the people that are there and uh um it is uh
it is very very special and when you go and you and you come back uh you're just
going to go did that really happen you know y yeah there are aspects of it that
are very dream it's not like you've gone to some really cool concert or something this is an experience this is something
you got to do yeah and it goes on for the better part of a whole week um so
it's it's just non-stop and and you think well tomorrow can't be any cooler than today oh yes it can be yeah because
one thing that our pal Garrick does is make every Star us bigger and greater
and more unbelievable than the last one you know last time yes I remember uh the
day after the star party we go down to the lobby of the hotel and bubble fooot is down there okay with his guitar and
he's just hanging out with us along with Tony Fidel billionaire Tony Fidel okay
yes just the nicest guy okay and um uh
you know it was just famous person after famous person was there and it was just
amazing it's really remark and they're all very vested in just sharing the excitement of Science of of their Arts
of a better world that we should have by this point in time here so that's it for staras that I had
I'll mention that we have uh we're now we finished the 50th anniversary year it's over now of astronomy and we're
into the1 weirdest Cosmic objects um which I drew up a list originally of 4
33 weirdest Cosmic objects which I'm planning to continue to horrify you with
for years to come on the global star party but we paired it down for print
for just 101 of them so that's out there now for the January issue so the
weirdest of the weirdest or the weird the weirdest of the weird the weirdest yes indeed yeah and here is our starmus
uh page so you can go to star.com this clock is something that Brian designed
if you saw Queen's we recent tour in the United States of America you would have seen this clock Motif in Queen show by
the way as well we got a lot of mileage out of this here but this is the logo for the starus that's coming this spring
here which will focus on the future of Earth because of all the planets we know
of out there now more than 5,500 exoplanets in 4,000 systems and there's
certainly billions of them in the Milky Way and countless billions in the universe in all the hundred billion
galaxies we still know no of one place
that will support life so we have to take care of this place that's right so
anyway we look forward to Scott to David at starmus I'll be talking a little bit more about it in the future here as we
run up to it and uh we hope that you will join us at staris it'll be an
experience like you have not had in your life as a science person so thank you Scott wonderful
thank you so much I would like to add something to this sir one of the things
that David said during his lecture was the jeene Shoemaker had quite a sense of humor and
not as an understatement Carolyn wonderful senses
of humors so yes to say we got so is an understatement absolutely yet you know
oh I'm sorry David go on go on and I was just going to say not only could they be very silly and funny and had a just a
wicked sense of humor but but when when you know when I knew first knew them when I was young way back in the day um
you know they were very calming and and you know they were sort of like
Guardians to you know what I mean they could there was a sense that they were kind of taking care of you as well yeah
as being really you know what I mean David yeah I do know what you mean but I'd like to share with you a little
story yeah yeah yeah the first night that I was observing Jean was that night
at at taking care of Voyager to going by Neptune it was 1989 it was my first time
with Carolyn and um she taught me the ropes and I was doing okay and she said you
know you're doing so well that we may run out of film so I went downstairs loaded the next
film and I came up I said Carolyn this is the last film and she
said I I know we're doing well but I didn't think we were doing that well we should have enough film to get through
tonight and I know my video is off afterwards I have to go out and buy a new computer which I hope I'll be able
to get and then the video working again but anyway to continue the
story uh Carolyn said no I I think we got lots of film I said no I checked this is the last film I loaded it into
the telescope and she started mumbling about it and we're taking guiding the exposure
and she said are you sure and I said yeah that's the last film but I have a plan what I want to do is I want to take
I'm gonna take I brought a roll of Trix black and white film and we're g to load
it into the film holder we're going to cut it up with the scissors and loaded the strips into the film holder and used
that and uh and I and uh she said I don't think that's going to work how you
g to develop this I said easy after we take all the films we're gonna put them all together and G to run down to the
drugstore they're going to develop them and then we'll tape them together again
with scratch tape put them back into the uh into the serial microscope and it'll
be fine and she said she said
David she said to herself how am I going to tell this fairly promising person
that he's full of it so she looked at me she said
David I don't think that's gonna work I said no
no we just we just scratch tape the films together it'll be fine and she
said David I have the very uncomfortable feeling that just been
had and I said Carolyn Shoemaker I believe you have that feeling because
you've just been had and we laughed laughed and laughed
and uh that started the humor and we never stopped and um that's fantastic and you
know I mean as you know as well or better than anyone in their lives David
they were the the kind kind EST most generous people with their time and attention you know they really were yeah
they really were incredible people and one night not so funny time when I was
with Carolyn visiting her and Flagstaff and uh she was driving me back to her home and she said you know there
are times that I kind of wish I'd gone with Tean and uh and I said well I can
understand that but you didn't and uh turned out that the world
got another 24 years of Caroline after that but I have a feeling
that in her last year she was really missing Jean a lot no doubt yeah yeah
and I think that uh in her last days she was thinking well I'll soon be with Jean
which is really where I want to be and uh and I think that's that's a good story I wanted to share with you
one wonderful thank you Dey and I mean it was when it happened you know it was 1997 wasn't it it was it was so sudden
and such a shock you know nobody could have anticipated an accident like that you know it was just a a thunderbolt out
of the blue of of Terror yeah yeah I wrote about it in my biography of Jean
that they're driving and they're happy and they're laughing and suddenly this
Range Rover appears right in front of a and that's the end of Jean's
life what wonder you never know what the the last moments are you know we we
can't predict it for ourselves or for anyone else so you have to appreciate
the moment and uh you know and make sure that you're you're saying what you need
to say and expressing what you need to express and uh and you're and you're
trying to do something good absolutely and and it's such a rare
thing to have known such a kind person who was so brilliant and who singlehandedly in effect invented an
area of science right impact geology and in effect
singlehandedly mostly created an institution as well the Flagstaff branch
of the USGS yeah you know that he basically on his own did those two
things he remarkable like the George Ellery hail of the USGS
you great thank you David for that and thanks Scott and we're looking uh okay a
great party this spring and we hope uh that you'll join us there in Europe
yes thank you so much David okay well this is not the last you'll hear about
staris uh we we plan to talk much more about it but uh but this is that was a
great overview and um made me really live some nice moments there so thanks
again David thank you SC okay okay so uh
uh David do you want to introduce John
Goss uh maybe he's not there right now or maybe he's muted I guess
not Scott I would I I will be the David that introduces John C yes yes please
even though uh Bob is very upset that I don't have my video camera on and wants a
refund but uh as an official member of the astronomical League I want to
introduce you to the person who is responsible in large in large amount to the success of
this organization that it has thousands of members and I'm sure a lot of you
listening to our program and watching it uh are members of the astronomical
League and John is representing it tonight and he's going to be uh talking
about the league and what it can do he's also going to talk a little bit about our next meeting in Kansas City which I
and plan to be at and to give a talk that I hope I hope is not going to have
me thrown out of the uh room but if if it is then I'll get David ier to come
and perform some mag of Tricks but anyway on this note presenting professor
John GS thank thank thank you David um I
don't think I've ever had an introduction quite like that before um you know I I'm supposed to say a few
words tonight and I find it kind of hard to do so it it's a hard act to follow uh
what's been coming up until right right now I mean I uh we just heard some some very interesting uh great stuff from
from a number of people and I don't hope hopefully I I can measure up to to those
standards so it's kind it's kind of a hard act to follow here well we we'll see what what's going on here but you
know when uh Scott said last week um I think it was late last week about what the general theme of tonight would be U
impacts I started thinking well you know I don't know that much about impacts I don't know if I can say much
about impacts but I I do know that we're going to be talking a lot you're GNA
hear a lot about Jupiter tonight so I thought oh okay well maybe I should kind of focus my attention on on Jupiter what
I could say some stuff about that so I am let's see what I can do
here okay great so my uh initial title was where's gany me well it's it's by Jo
and you thinking well what what am I talking about here well this is something uh if you I like to speak
about how people can enjoy the night sky and what what they're looking at and get stuff out of it and so I kind of look at
myself to say to see uh what I've gotten out of it so let's start in this way I have a
liyi which pretty much describes what I'm going to be talking about for the next few minutes gany made emerges
silently moving in darkness it hides now to see the giant galileon I vow minutes
pass nothing yet standing cold won't regret a faint glimmer turning brighter
brings oh wow I believe one of the the great things about stargazing about being
looking through telescopes talking about astronomy is experiencing experiencing the oh wow
effect and I think that I in my own top 10 uh reasons for stargazing this is
number three don't worry we're not going to go on to number two and number one tonight this is this is not number three
uh when when I first did what I'm about to show you uh a number of years ago now
I think that's those were the those really were the words I used was oh wow you know this is really something to see
something something really really cool because we as amateur starmist we love seeing
things with our own eyes we love seeing the universe the way it is all the Wonders that it
has so you go out tonight no don't don't go out tonight stay tuned into to this
but another night go out on if it's clear uh see what the sky has to offer
well you will see soon uh Jupiter in the sky uh among
all the the uh constellations and stars of the late fall Sky early winter Sky
since is something to see so let's talk about Jupiter and and and how this impact stuff affects affects our views
here like to share with you a diagram that I cooked up this is something I
tried to make as accurate as I could it'll become apparent where we're going with this in just a moment but uh I'd
like like to describe what I have have here this is just a simulation as far as uh uh Jupiter go the planet Jupiter is
right in the center and it's just a simulation of that it's a it's from a picture I took a long time ago I'm not a
good as photographer uh um I haven't gotten much better but uh Jupiter's in the center
and just above it to its left you see a DOT for gany meat and just to its left
you see another dot which is Europa and I drew in the orbit the orbit of those two moons and I also Drew in the shadow
of Jupiter from where the sunlight is striking the planet so the shadow extends out like a
little tail off to the upper left of of of
Jupiter so there I took all the lines out there's ganim in
Europa what I have to emphasize what I have here is a simulation these are not astrophotos that I made uh but uh
hopefully it's representative of what I what I want to say talk about Ganny me going into
Eclipse um it's a pretty neat thing to see through a telescope you're going to need a fairly high power to experience
all this just right and what I mean by high power would be be like 100 100 times or more so it's it's not extremely
high but uh certainly not low power so Jupiter Jupiter's moon gim
orbits the planet and it goes into Jupiter's Shadow which hopefully this
simulation will will do right here it takes a while to do so it takes a number of minutes so as you're watching uh gany
me go into Eclipse you just see it slowly slowly disappear after a few
minutes and then it's gone because now it's in the shadow uh Jupiter Shadow it's being
eclipsed by Jupiter now that's pretty cool to see because here you are watching an eclipse that's taking place
400 Million Miles Away something like that it's not something people see every day and it's it's it's pretty neat for
me it it was sort of the basis of the oh wow moment but a better one at least for me is coming right
up so now jup or excuse me gny Ms in the shadow of Jupiter Europa continues to
cross the space and eventually transits the planet I'm not going to show about transiting the planet because you have
the bright Jupiter with the bright Europa in front of it you just don't see it very very well at least for that not
for this demonstration but you know there you are watch it you're not watching gny me
anymore because for the next two hours and four minutes approximately it's in that shadow it can't be
seen John then sorry for interrupt you know I I you know that I did exactly
like that a couple of days ago I was capturing there but in this case I would
try to capture the eclipse of Europa but I couldn't you know I
it's it's amazing when yeah when when the moon goes
behind the planet ER it's amazing but then it will have to appear you know
because it was that but it wasn't see it because the the moon has the shadow of H
there you know but I couldn't capture it but I know that in some darker place was
Europa but I couldn't see when the lights of the sun came again to
Europa because the clouds more later bother me but anyway it was
amazing to to to try to yeah you know capture it or and also watch it for the
first time so oh yeah that that wo effect was shocking yeah oh wow I think
it's pretty pretty pretty thrilling first time you see there it is and then
it dims down and it's gone uh and then part two is coming right up here so now
you have uh yes thank you Ganny me moves out of the Shadow hope I hit the right button yeah
here it comes this takes many minutes now I'm speeding this whole thing up because you don't want to sit here for
16 minutes watching this G come back and and into full sunlight again but there
it is and for me personally that that that was a real oh wow experience
because I couldn't see anything and then all of a sudden I start thinking is that
is that a little faint light right there is that it I go yeah yeah yeah I can see
it it's brighter and brighter and brighter and boom there there you are
you you just saw I guess you could say you saw it even though you really didn't see it the
whole eclipse of gany me uh as it disappeared in the shadow went through the shadow and then came back
out so what you now have is uh Ganny me has progressed to the other side of the
Shadow as it pops back out and it you know goes around and absorb it um just
to be clear Europa is still on the face of Jupiter so it's gone for forget about Europa but something like this go out
and look this may be an oh wellow moment for you you don't need a super telescope
or anything like that to see this as I said 100 magnification okay well it's kind of in the high side for for some
people but it's certainly C certainly
doable emergence time also disappearance time it about 17 minutes to disappear
into the shadow another two hours to plow through the shadow and then another 17 minutes or SOA pop back out so this
is all all very gradual I'm going to talk about Europa and I IO Ju Just just a little bit because um because that oh
Ohio iio revolves around Jupiter so quickly so so close to the planet it
only takes about four minutes to go into eclipse and with Europa about
six now it just so happens this is what I uh worked on earlier today to figure
out what what's going on right now uh we did have some events a few days ago but
right now right now uh gany me is in Eclipse uh from from from Jupiter Shadow
right now now don't go out and look at it tonight don't go out and look at it tonight because I want you to stay on board here and see all the cool stuff
coming up and also because you'll see you have a second event down there that's been circled uh one week from now
uh Gan me is going to do approximately the same thing these times I've listed 9:45 11:49 and so on that's all Eastern
Standard Time so you'll have to adjust ju uh adjust the times for whatever time zone you're in but go ahead and and try
it in see if you get your own ohow moment also you'll notice that Europa
and IO uh happen to be kind of paired uh on certain nights so you can see both of
them do the this and a couple on Thursday night you got um europ and IO doing this but that's like an hour and
half apart so that means you got to stand outside for an hour and a half but if you look on what do I have
December 28th they're just six minutes apart so it's two for one right there as soon as one comes back out of eclipse
the next one starts uh so you get two moons right there to see and it it's
it's a great thrill to see this stuff and it happens slow enough that if you have somebody with you you know you can
show them uh the view through the eyepiece and it doesn't happen and just a few seconds so they can have a good
good look at this too and you can show a number of people as it's coming back in or going into Eclipse I think that's
that's that's a lot of fun and it kind of you share the hobby you share this
aspect with other people and I think you'll you'll see some some good good stuff in return now the astronomical
League uh I'll give a little plug here for the organization so we have a number of observing programs which which help
help you uh obtain this oh wow factor in which gives you a bunch of activities to
do and some of these are really going to hit home for you you're really going to going to going to like them the um this
idea of Jupiter and his moons all the stuff that it does like we were just talking about the eclipse well there's transits there's
occultations um there's Jupiter itself look at stuff on Jupiter but we have a
number of programs here which which encourage you to go out and look through the scope and see the stuff for yourself
remember as astronomers we like like seeing this stuff with our own eyes you know this isn't textbook stuff well it
is textbook stuff but you can see what the textbook is talking about experiencing for for yourself seeing
something that's going on that's 400 billion miles away seeing something that changes you know so many times in
astronomy you look at dim galaxies and nebula and stars and so on they don't change but this in real
time in just a few minutes you can see something happening so I encourage you to go out and try some of this stuff uh
on your own with your telescope look at the sky enjoy some of this stuff and
enjoy the global star party because it has a lot to offer that that wraps it up there Scott
hey all right well thank you thank you well thank you great all right um so we are uh uh
probably needing to talk a little bit about out the astronomical Le convention uh that will be happening in Kansas City
let's not foret that and um uh you know uh we did kind of mention at the
beginning uh uh David Levy and myself plan to attend uh David I think is a
keynote speaker there so um so anyhow uh
what more do we need to know it it'll be a great time um well it's July 17th through the 20th I kind
of stop and think about that I don't want to tell you the wrong date 17th to the 20th in actually it's in Overland Park which is just South Kansas City but
um you know why why why should you come to something like this well you start thinking about I I can't compare to
storus but I can tell you a few things that at these conventions who you're gonna see right next to you has its own
thing well yeah yeah you see well you'll see characters like like scy Roberts
okay well good okay but you also me meet uh research astronomers uh space mission
Specialists um university professors uh vendors uh who have all like Scott with
all the cool stuff you you'll get to meet uh astrophotographers Sketchers visual
observers people who are interested in variable Stars people who are interested in deep Sky observing people who love
the moon uh you know a lot of stuff a lot of people
there and friends there and you're G to make new friends yeah oh yeah well a lot of these people come year after year and
you ask yourself why you know um these things are held around the country and
so it's it's really taking a lot of your vacation budget time as well as some
money to go to these things but people keep doing it and that is why because they keep meeting uh I I guess I
shouldn't say like-minded people but people who enjoy the sky and they want to learn stuff and share their own
experience it it it's hard to describe that's right
well I can tell you that it's um it's also great to be there because
of all the recognition that goes on at the astronomical League conventions they do all you know if you there for the
awards banquet it's just backto back recognition for from very deserving
people uh and uh it's it's um it's wonderful also to see the youth uh
recognized uh in the way that the league does it um you know there's there's no
one that even comes close as far as an organization that recognizes Youth and astronomy like the astronomical League
does oh yes so you really and you just feel the energy of all of that and it's so cool so well you know you think about
who um some of these people um the awards that we give out we we
don't have these these names for these awards that I'm about to say but like that the the person who's influenced
amateur astronomy the most over the last year or the last few years you know we about recognize those people recognize
the per the the person who spends hours every month creating throwing together a
newsletter or maintaining a website you know that's right that that's all extremely important that that that's the
glue that binds us all together is it's it's that communication like like that
you know you have the astrophotographers the great ones for that SE about about the students all types of of awards for
those and I have to thank um I'm going have to thank a lot of people for this uh Scott Roberts himself for helping uh
promote and sponsor some of these things but we also have astronomy magazine sponsor um American Astronomical Society
sponsor we have people like uh or companies like uh Orion Telescopes uh
Woodland Hills telescopes and Camera uh I better be careful because I'm going to forget some but there are a
number of others out there uh um telescope Trader sponsoring our sketching competition and I mean the
more people we get together there's too many to list actually because there's so much support and everyone coming
together and it's local you know uh so it's definitely something that you want to go and experience uh you're going to
learn a lot there's great lectures that go on uh workshops and um you know uh
collaborations that you can uh get involved with that some of it does um uh
you know uh helps to introduce you to the professional world and these pram projects that go on and so the
astronomical league is definitely a great platform to be involved with they have 80 there like over 80 um uh
observing uh programs uh you know you're going to become a better astronomer uh through
your experience in the astronomical League and it's all supposed to be fun and it
is fun okay I forgot to add that part but it is really a lot of fun and we we make sure of it so okay thank you Scott
thank you all right thank you so much John take care okay all right so up next
is um Robert Reeves uh now we have I I
got like an immediate email from Robert uh once I uh we talked about the theme
being impacts and uh of course the moon has shows all of its impacts from you
know I guess hundreds of millions I I don't know what the oldest impact is but uh uh I'm sure Robert Reeves knows and
so thanks for coming on to Global Star Party Robert well glad to be here and uh
yeah the theme did Jive kind of with my primary theme nowadays of the Moon um I
noticed that quite a bit of discussion about Jean Shoemaker early on in the the program so I need to throw out my
particular Jean Shoemaker story um he was guest um speaker at the Texas Star
Party oh I forget exactly what year but uh he he was one of our invited keynote
speakers and um he was so down to earth as swear it was like 1 in the morning
and we're sitting on the front steps of the Walnut cabin where we where we hous the the keynote speakers there at the
Texas Star Party and Jean and Carolyn and I chatted for hours
into the night that's and um um he he didn't bat and ey he answered every
question explained everything U I wrote it all up into a um interview of him for
astronomy magazine that uh I forget who was the uh editor back then it was pre ier days um but u i um sent it off to
Jean for his approval I didn't want to put words in his mouth and he took the time to hand correct everything that was
it quite right in that whole interview and he was so nice about it and that
always impressed the heck out of me because this guy is like the premere of an entire science and AST in in
astronomy yet he he he took the time to um to talk to with me way into the early
morning and then u u make sure that what I said was was spot on so that impressed
me greatly um he he was definitely one of a kind but moving on as far as impacts go yeah
the Moon is definitely the Touchstone for that uh
um before telescopic astronomy began we could look at the full moon rising above
the Horizon and see the evidence of impacts but with a naked eye but we
didn't recognize it um even through the uh whole telescopic
era from from Galileo up to the late 1800s uh people didn't recognize the
impact nature of things on the moon because there was no cories for them recognized on the earth um they had
nothing to compare to understand what these things were on the moon uh we see them uh these giant impact basins on the
moon as the face of the Man in the Moon uh the lunar Seas creating his two eyes
his nose uh his lopsided mouth um these are all giant impact basins on the moon
created by asteroid strikes um almost 4 billion years ago but um Earth got
shellack just as bad as the moon did back then H but U Earth's weather
tectonics plate tectonics oceans um uh the Earth is a very Dynamic Planet it
healed all of these wounds and now it takes a very specialized geologic eye to
recognize impact basins on Earth um there's something like about 190 of them
cataloged and if you know what to look for where to look for you can see them but back then nobody knew what they were
so U we looked at the moon in mystery didn't recognize what we were
seeing and um we went through the whole Apollo era went to the moon landed on
the moon gave up the moon didn't go back uh and still didn't really fully
understand the impact nature throughout the entire universe or or or solar system um we sent Mariner spacecraft to
Mars oh Mars has craters too cool well of course it's closer to the asteroid belt we kind of expect that but it
wasn't until Marin 10 went to Mercury in 1974 well after the Apollo program was
over uh and saw that mercury looked almost like exactly like the moon
heavily cratered all the way down to uh uh raid craters just like on the moon
the only thing Mercury doesn't have are the massive Maria like the moon does so uh suddenly it became very evident that
all the inner planets were massively bombarded uh billions of years ago by
asteroid impacts only the Earth has healed its wounds and uh and doesn't
show evidence of that but uh when you look up at the Moon you can see that so let's uh let's do the great experiment
and do the screen share thing and uh um
see well here we go and uh yeah my uh title slide should
be up hopefully and uh we're seeing thumbnails well here we go again um says
I am screen sharing so let's stop the share and
um well okay oh now I've lost you where's
where's the zoom oh I hate this there we are okay let's try screen share
again and um now do you see my title slide yes
great all righty okay so um except it want Advance H okay have to do it the
other way now those of you who have been paying attention in class every time I
talk about the moon I show this one slide there are two primary landscape forming processes on the moon volcanism
and impact cratering now anything you see on the moon was created either by an
impact blasting a big hole in the ground or subsequent volcanic modification of
that impact and it's the same on other planets Mars covered with craters Earth
was covered by craters Venus we know has many craters on it after you penetrate
the uh the thick atmosphere with radar and Mercury of course looks almost like
a a a twin of the Moon because it's so vastly cratered so um this impact
mechanism is is kind of universal throughout the solar system the outer moons or the moons of the outer planets
all covered with craters as well unless they're an icy Moon that heals itself uh
but you look at all the moons of the outer planets and invariably very heavily cratered as are the asteroids
the asteroids that we've U looked at up close they've all been pounded by
repeated impacts so whoops I didn't mean to do that I wanted to advance it the
oldfashioned way but when we're dealing with the moon um impacts react
differently uh depending upon the size of the impactor and the size of the resulting impact now if it's a fairly
small asteroid and it blasts a hole in the ground only about 10 miles in
diameter about 16 km in diameter uh the physics of the impact will create what we call a simple crater just a
bowl-shaped crater it looks like somebody took a giant ice cream scoop and chunked out of a big hole in the
ground but Above This Magic 16 km size
the Dynamics of the impact are such that the subsurface Rock rebounds back up for
after the blast it creates a central Peak very much like cerus crater and the
strength of the um lunar surface the crust is not sufficient to support the
walls of a crater that's big so they collapse and tumbled down into the crater and form a series of terraces
now if the crater is larger than 300 km by definition we no longer call it a
crater it's now a basin and U the old 300 kilometer
size uh U for the the beginnings of a basin is
kind of fuzzy nowadays because now we're finding smaller uh features on the moon
that have a double ring around them U impact rings are associated with Basin
impacts so we're we're finding smaller basins on the moon now recognizing them
I should say we've seen them all along but we're recognizing them as basins and they're less than 300 kmers in diameter
so the definition of a basin is is getting fuzzy but uh it's all part of
the understanding but we're getting better and better at it and uh I didn't mean to hit that uh but that's the next
slide I want to show anyway so getting back to this thing about how we could see evidence of impacts on the moon with
our naked eye all the way back to ancient times pre- telescopic times when
astronomy first became a science and people started charting the sky and
noting the movements of things in the sky and predicting their movements we could see the moon as we see it here the
the full moon rising full moon up in the sky we could clearly see um these round
features dark features on it but we did not recognize them as being impact
basins that filled up with with Basalt and and created these dark areas we call
the lunar Seas the uh uh the Maria that formed the face of the Man in the Moon
but this evidence was staring Us in the face all along and even up through the uh 1800s almost the late 1800s people
still didn't recognize what it was it wasn't until a geologist not an astronomer fellow named Grove Carl
gilbertt the chief geologist for the US Geological Survey and um here's a u um
the plot circles all the way back again because Jean Shoemaker was very much associated with the USGS uh not
necessarily as an astronomer but as a geologist so here we were a hundred years before and
uh Gilbert used the um Naval Observatory
refractor in Washington DC to observe the moon for a period of 3 weeks and he
noted that the embrium Mario embrium appeared to be in a great circular Basin
and he based this assumption on looking at the territory around Abraham and he
notice radial grooves streaking outward uh particularly toward the southeast we
call this these features nowadays the embrium sculpture but these were created by the chunks of material blasted
outward by the impact of the asteroid that created the embryon Basin that later filled with theault to create Mar
embrium now Gilbert recognized this in the late 1800s but his U write up about it was
buried in an obscure in-house report that nobody noticed for almost 50 years
so um once once the cat was out of the bag it became apparent that what we've
been looking at all this time but wasn't until uh evidences came back from the Apollo era that people finally believed
that all the craters on the moon uh major craters are of impact origin uh it
was still thought that volcanism uh created some of the craters even up through the Apollo ER so uh it was a
mindset that took a long time to u to turn to reality so let's see if we can move on
to the next one yeah so as we look at the these these Mario in a telescope uh
we plainly see they are round uh here we're seeing Mario nectaris um next one
we'll move back up to embrium I've been talking about it all along and we clearly see that it is cradled in a
circular Rim which is the uh the rim of
the gigantic crater that is the Basin that is housing these these uh uh or
hosting these Mar now we have to realize the uh the Basin under the Maria and the Maria within it
are two different features the impact Basin formed first and subsequent volcanic eruptions modified the Basin
and flooded it paved it over flat as a parking lot and uh created the
Maria yeah uh here is Bailey um a basin on the near Side of the Moon that did
not fill up with Maria and hopefully you can see my cursor slowly circling this
rather large flat crater on the southern part of the Moon near very close to the uh to the limb uh Bailey is 302 kilm in
diameter so it was kicked out of the crater status and is now recognized to
be a basin and um there's actually 70 something basins on the moon um um not
all of them filled up with balt to become a a Maria let's move on to the
next slide and sure enough uh here we see a map of the Moon um showing the
near side basins and uh we see the embrium impact Basin up here that we've been talking about uh nectaris impact
Basin that I showed earlier um the Moon is um kind of unique in that it it has
several uh features that you wouldn't expect uh considering it it's proximity
to the sun close to the Earth uh the moon has some of the coldest places in
the solar system up at the poles that never receive sunlight colder even than the planet Pluto but the moon also hosts
the largest impact Basin in the solar system and unfortunately it's on the
back side of the moon the South Pole Atkin Basin spans almost 2,000
kilometers uh we see it here this following my cursor circling from the
South Pole almost up to the L lunar equator uh this this massive Basin PR
nectarian uh over four billion years old uh the moon got walloped bad well yeah I
mean uh it couldn't get hit any harder without shattering so um um it it is the
largest impact basin largest crater in the entire solar system and it's right
here in our backyard on the back side of the moon so moving on
here now um for many years um we could see the
mountainous Rim near the South Pole of this South Pole Atkin Basin not really
recognizing what it was we didn't uh deduce its um existence until after
spacecraft mapping of the Moon um the backside of the Moon U wasn't it
was unknown until the space age but from Earth we can see the mountainous rim of
portions of this along the southern Rim uh the bumpy edge of the Moon uh we call
that the liit mountains for for oh gosh over 100 years but nowadays that uh that
term has been dropped but um we could see portions of it from the from Earth
but not recognize what it really was of course here we see a clavus
crater about 22 something kilometers in diameter uh moretus right here more
conventional looking fairly large uh gosh almost 100 kilometers of diameter
so now we're getting into the smaller impacts if you can consider something that makes a crater 200 kmers wide a
small impact well it certainly is compared to the South Pole Atkin Basin so moving on morus again and more of the
little bumpy mountains along the bottom Southern edge of the Moon that um denote
the outer limits of the South Pole Atkin
Basin now getting back into more conventional impacts not basins but
Craters of course Tao crater the youngest large impact on the moon I
think it was created about 108 million years ago so uh the FL flash that
resulted from the asteroid impact that struck the moon and created Tao crater
surely startled quite a few T-Rexes on
Earth so and of course one of the beautiful functions of a of an impact a
large impact on the moon is the splash of uh ejecta that fans out in all
directions and create creates a ray structure um the craters that are older than a billion years the rays are faded
because of the constant churing of micrometeorite impacts but the Tao is Young so we still see this this spread
of rays radiating away from it in all directions and then getting closer to
Tao we see this curious dut around it um dark dut uh we see Tao crater itself a
dark band around it and then the bright Ray structure well the bright uh the the dark dut is actually the actual color of
the lunar territory before the uh Ray material draped across it uh the ray
material arked over the territory in this doughnut and started splashing down
further away uh at least a crater radi away so uh we
end up with this this very distinct dark donut around Tao and then um wrapping up uh about
impacts um cernus Crater of course one of the most spectacular on the moon uh
we see it almost face on because it's at the equatorial latitudes and and we're
not looking at it a slant we're looking straight down its throat uh so we get a
really good look at its structure and the ray structure Fanning out in all
directions and getting closer to it we start to see well is a classic complex
crater with uh multiple Central Peaks the uh walls have collapsed into a series of
teres and uh they're secondary craters radiating out in in all directions and
the ray structure of course and closer still uh here we can
see the strings of secondary craters showered out by the impact that's the
the asteroid is smacked into the moon uh vaporized and uh the explosion of the
the vaporization of the of the asteroid is what blasted the whole of the Moon
craters are not bullet holes in the mood where where something hit and uh punched a hole in it uh craters are created by
the explosive vaporization of the impactor when the the tremendous kinetic energy of cosmic velocity 20 km per
second or more uh comes to a rather sudden stop when it hits the moon U
that's converted into heat and uh the sudden burst of heat tremendous heat
vaporizes the object and it explodes like a bomb so it doesn't necessarily
matter what angle the impactor arrived at it's the resulting explosion that
creates the the crater that's why a majority of the craters on the moon are round so uh here we see
the uh U fragments of ejecta thrown out in all directions have created these
These Chains and streams of of secondary craters uh surrounding this so uh it's
not necessarily just the impact itself uh um
there's other effects as well the the the formation of the crater Rays the formation of the secondary craters the
effect of uh the impact on surrounding territory it modifies other nearby
craters uh degrades older craters by showering them with with ejecta so
there's a constant modification of the lunar surface as things continuously
bombard us so uh I think this is the last yep so I'll conclude my usual Slide
by saying there's much to love on the moon and uh I enjoy I I uh invite you to
come out and join me on my playground uh the Moon is in our backyard most of the
month uh the moon laughs at light pollution uh the Moon is easily
accessible in any telescope uh a small telescope will give you just as much enjoyment with the moon as as a very
large one and in some cases works even better if the seeing is is not good and
uh uh bad seeing will will adversely affect the view in a large telescope so
U impacts are a way of life with the Moon um it's a record of how rough and tumble
the solar system has been for its 4 and a half billion year Lifetime and you could look up from your own backyard and
see this with your own eyes and appreciate how lucky we are to live on
an earth that's protected by an atmosphere uh stops a majority of this
uncoming junk from from striking and uh um doing bad things we do not want to be
around if another chickalo incident occurs um because we're not going to live through it so uh look up and enjoy
and hope it doesn't happen anytime soon great great wonderful well
um thank you for another amazing tour of the Moon Robert so my pleasure I love it
I love it so um uh great uh uh our next
speaker is down in Argentina and is none other than c Caesar brolo Cesar hello
hello here we are can you hear me good how are you good how are you hello is it
amazing the internet just lets us uh talk around the world like this yes yes
absolutely and it and share it with everyone we we we are taking everything
like something normal but we are in seconds talking about everywhere we are
maybe at I don't know maybe 15,000 miles I don't
know uh from from my from buid Aransas maybe um well uh tonight it's a it's a
it's a Tey layer of cloudly of clouds um uh it's it's not
for show something uh from my telescope but it's
a night where uh I can I can uh we can
talk about uh some impacts CR impacts in
Argentina uh it's a it's a kind of of uh different
different shape of of PR let me share
the screen
where is [Music]
this sh
well right here well we first of all I
can show you in this map I like to
start uh talking about where where we are and where
is the CR I like to show where is where I am
where Maxi [Music]
is and um well we are
going here is Maxi and she I am here
now yes yes we yes you have storm here yes here here is a is a from Storm
from in this area over over the head of Maxi this is the riv Rio de La Plata
River Plate and we are going to Cordova to the center of
Argentina it's a province Center of
Argentina and this uh an area of the south of the
province of Cordova the city is of the city of Rio
quto have uh three impacts of C very
very um how do you say very different the shape of the
CR comparing comparing the CRS that we know uh as CRS
normally we think in CRS uh impact RS rounds like uh Robert
show us uh in in the in the moon but I I I
know that maybe Robert know this kind of CRS with the when the angle of the impact it's very very close very
closer you have this kind of
impacts this is an a farm area in the south of
Cordova and you can see how normally is full of vegetation
vegetation sorry is an area that
normally uh they can't uh they can work for for Farming or they
can farming it's very
interesting let me show you this one are the
twins and another one
is here the the big one is around 4 K kilomet by
1 two 100 1 kilometer 200
M and think in this well they the farmer
can work in this area the SOA give the soya in Argentina
give a a very important gra amount of money and of course that it's okay the CR in your
front but if you can work inside much better of course that the depth of this
CR is around four Met 10 Mets in different areas and let me show you a
presentation that they have around about sorry uh more of of the
connect Ed with the this CS is very interesting because I found few
information but some pictures that that
um photographer took in the area um some people that make make a a
um a website that I I later I put in the comments in
YouTube because I like to show the the resource because are not my resource if
not I only I'm search something about GRS in
Argentina and I found H this and let me show
you well something that we can we can um
see in in this is the change of vegetation of of
the change of the
pattern in the in the area that have of course that slower slower yes
terrain is very interesting because you know it's
something that that is very particular
I show you I changed my presentation to my
presentation sorry you can see the presentation yes okay well two things
that I'll show you to the audience tonight uh Rio impact cor CS um that we we saw in Google maps and
with the sellal image and um of course a something of the last Satur dat where we
work in our um our foundation V Cosmos
in a special event in San Miguel um in San Miguel City about the
you know about the they they talk Li the the night of the books or the book Night
the books night uh especially for books uh talking with a science astronomy you
know um well I'm star
here it's the same and here you have the maps the
Twins and the northern Vines the drop is another Another
Part another another impact the moon group is another small impact and later
when I finish I finish the the presentation I show you something very
particular where is the city of Rio quto is in the path of the of the impacts of
course that this impacts maybe was between 2 10,000 years
ago because it's it's a Nuance it's not of the time you know one million of
years is a between 10,000s uh or to
2,000 years ago in astronomy talking is
yesterday yesterday in the morning yes one second ago yes yes absolutely well
this is one of the first of the first satellit satellit uh pictures this and
this this one is is newest in color [Music]
mhm this one is a is um uh in the 9
970s uh uh one of the first uh photo
photographies uh from from Air photographies here is an a part of the C
this part is really uh easy to sorry
is easy to understand like CR be because you have this amount of material and the
border of the CR you can see uh um this one was in a period of of
dry um dry weather really dry weather
and it's an all photography from from the 80s and is um it's empty of ation
and you can see the shape of a part of the CR but
it's very large it's really a BL or a long CR it's not wrong of
course well here I I found in the in the we website that have information it's an
old website I don't have a new website um it's a website it that
have um two articles of two different uh
magazines maybe you know by Peter H Schulz and Kelly V that they are um they
are journalist in sky and telescope and maybe it's a it's a it's
um investigation from from the 80s and this AR article in sky and
telescope and this one is another article in natur magazine it's very
interesting the things that I found in this
website here is the one of the first um
I I um seeing or watching uh pilot of
helicopter that um that that he he he he
recognize the the different things in the in the terrains and they start to to
think that this was a impact of
metos here you have one from from this from the this uh from this guy from the
this pilot is the picture in this area where
you you have the first the first knock of the
impire this is very interesting isn't in in the in the time where uh people from
natur came and they they found a part of
the terrain with Dooms and actually it's a picture from
few years ago where the area is
fed and do you can see the border of the CR with
vegetation this is another picture from the border of the CR from inside the CR
watching know to the to the border of the CR with an area that I show earlier
that is is uh is working for for Farming of first
is planted and here do you have many many
places of uh ponds because you have a lower lower terrain where the the the
water drain um is it's I I'm now I'm very interested in visit really this
place because um this one is are pictures that I found in internet in fck
or I um it's very interesting to to to go really to fill this this uh
area of of impact is really really interesting well here is one of of the
of the pieces that were found uh and have an and side with small
brights um uh bright particles that are typical of of uh
young impacts this is why two things that the people knows where you can see
um in a flat rain this kind of CR very
very flat really low low deep CR very
long and they know that it's no more uh
older is not older than 10,000 years by
the shape of the CR because don't have more Eros erosion maybe it's in
English erosion yes uh um the particles
that they found have this kind of it's a like a bright small bright H particles
that is typical of the young younger part of metor it's a they they found
that is a kind of of uh carbon
metor and maybe this uh this metor this meito H
make a a contamination in an area maybe
uh in the center of our Ina in this time uh that could could
kill uh many species in the area by the G the gas of of the carbon of
maito it's very interesting that how impact something so simple like a small
metor and I'll show you later where is the
city uh and the size of the city comparing with the size side of the
CR well this is the the experiment where they
they comparing in a laboratory with a small impact they
know the this the shape of CR and they determined that the angle was really
really closer and uh well I another
um thing in my presentation um it's the work that we
make uh with the foundation where we are restoring the all Observatory and every
year we make uh we make we participate of um
of nights book and uh we uh work in um
showing uh like I as volunteer showing to the people especially to this
Saturday night was Hooper that's great a lot a lot of
people that we receive uh Friday and Saturday this was from
Fridays um Austina is an Specialist of of the
in stones and mineralist and she talk a lot about
minerals um how can be minerals in another words or how we know about
minerals in another words on the moon for
example this is Austin maesi that work with the telescope and he he learned in
two hours the entire system on bmca of explor scientific to work with
the with the uh the mo exos
2 while here more people watching who Peter this one is very interesting you
know this is an meteorito this is a a meito
uhuh we um Jor ransi is one of our
collaborators the big one yes it's owner of this metor in Argentina you can sell
or buy a metero uh but you can be an owner only
for educ educational proposal oh I see so they do not allow the buy or sell
meteorites yes yes and here to um it's
totally illegal um it's totally illegal in Argentina sell or
buy um H meteoritos meteoritos and fossils of f
real fossil of fossils yes yes it's very it's something that of course that the
poor people is need to sell in their you know
but we're so corrupted the system for that that many many years ago the
government I don't remember how many years ago they tell don't sell more
Especial fossils maybe Meto is totally forbid for Biden but um you know they prefer the
government prefer okay it's only for museums education and it's okay um I
don't know but it it's a great it's a great uh um you know a great expire
experience had to that in the foundation we by this guy that is a specialist in
in asteroids and chemicals and is in a chemical engineer chemical
engineer um and he have this and he bring to us
this for the kids to touch think in the in the sensation of a
toing uh metor from from the space from another world it's it's amazing and this is
something that really we enjoyed uh and a lot of kids came to our
stand to enjoy this and this kind of of things don't have
price it's much better than Sorita and here is Jorge ranski Jorge
work is a work in the time that the observatory
functions 100% this guy is a is a legend and for
us it's so it's a treasure that we because he knows every part of the
things that we have in the observatory the old Observatory and today he is a a
great support to us uh because he explained a lot of things and when we
when we make this kind of events H he love to teach to the kids these things
and this is amazing J ransi is a ler here is the
director of Observatory my friend H Santiago
M here is the m how many people came to this event it looks like a lot yes maybe
this is this is four h four blocks in a part of the street where do
you have a you a running a running way a running place to to make a you know and
in and the the the major of the city um
make this from I don't know how many years ago and every year they they put
four blocks of full of stands of store books or
libraries um educational programs or foundations or groups like like us uh
maybe I don't know maybe it's over it's over 20,000 people wow it's over over
because the entire city came and this is the entire night it's really I don't
know how many people we attend with the telescopes yeah you know no no no no
it's incredible yeah you just lose count yes yes as our our Observatory is full
of interesting things that every day we found between the things and we found
this one that is a suite for you know for work in a volcano maybe you know and
we uh we had the idea with with one of
our members to to make to put the suite and uh and
you know uh play with the CH the kids uh with the people the the kids was amazing
because they the the the you know maybe
the the younger kids thought that oh an
astronaut you know here and was so
so so fun and the the kind of you know
when the kids are going W you're an astronaut it's so of course that we
explain that it's not an Astron is well for for the for the older kids of course
that they were more interested this is not an astrona suet what is this you
know was a a a lot of f we have with the astronaut
suits and here is the explor scientific working the entire night with a I don't
know maybe maybe this this file was around I don't know maybe 3,000 people
wow cing and coming said how many hours we are W yes yes we we watch h
whoer uh you know the a lot of a lot a lot of time really was so so fun so so
grateful from the people you know here is the is a like the the that's great
Outreach thank yes yes all the liks are the entire the the
and and I'll show you fastly where is the
city ofto to compare to
compare how dangerous
is pink is what the the asteroids the
the metor came from the sky 10,000 years ago or maybe
2,000 years ago yes compare the size of
this the NASA information about the impact of
those uh that made those craters uh say that it was you know many
times the um Power that made the uh meteor crater in
Arizona um and many times the um the power of that leveled the forest in t
tunguska um yes was terrible because maybe sometimes when the angle is small
the area is is more dangerous or more aggressive it's very
interesting don't standing in its way that's for sure yeah yeah yes well thank
you very much thank you Cesar thank you it's it's a fascinating to know about
these uh uh these impact crators or what also called an astro blem uh we have an
astro BLM uh in I'm here in Arkansas we have one in Oklahoma not I mean within
driving distance so uh and it's not very well known but um it's
there thank you so much Caesar that's great uh it's a it's a pleasure thank
you to the all audience to thank you so much okay okay good night Caesar thank
you good to see than you thank you to us thank you okay well up next is um Bob
Denny uh Bob is uh uh famous for uh lots
of things uh that have to do with uh Computing um but also he is a Avid uh
astronomer and uh loves the night sky and he loves uh sharing um the
technology of what can be done with telescopes and so thanks for coming on to Global
star party it's been a little it's been a little while it has been a while
indeed yes sir well thank you very much for having me and Cesar that was really
wonderful I I very heartwarming in fact all the previous presenter presenters
really nice I I don't want to take up a whole lot of time this evening I I am
more of of a technologist than I am an astronomer um Scott and I met many years
ago uh I will go through a sequence of old stories first before I get into the
technology side of what I want to talk about beginning with um showing you a
picture of someone that David Levy mentioned earlier who is Mr Jim Scotty
let me just put his picture up here can you see him now yes
yes okay she that's Jim when David was describing the discovery of sl9 he
mentioned that the first person he called was Jim Scotty who I met probably
five years later this was in anyway right when when the discovery occurred was in 75 right is that right am I
getting that date right or 74 I forget not no 95 or 94 which one was it no it
was 93 March 23rd 199 okay so so that means 7 years later I met Jim 6 years
later in '99 um at a chance visit to Kit Peak I
was had ended and sold a company and was had moved to Arizona and just went up to
Kit Peak by myself one night and ended up in the cafeteria and ended up talking to Jim and some other people at the
table just I didn't go to the visitor center I just went to the cafeteria anyway um and he invited me over to the
spacewatch telescope gave me uh a uh tour and a
technical tour and told me how their drift scanning worked and showed me how it all worked and it was fascinating and
that's what sucked me into astronomy so Jim Scotty thank you so much for
providing that magnetic force that I used to live below kit Peak when I was
in college at a place called three points or robish Junction and we could look up at kit Peak you know I didn't
never give it that much thought I was an electrical engineer anyway so thank you Jim Scotty for that um and David your
path crossed with his before mine now let me stop that
screen share and come back to you all um the next thing I want to tell you about
another short story was I met David at the rockand Cross Ranch in paen
Arizona I don't remember why I ended up there Stevie and I and her little white dog went up and we saw David speak up
there and then the biggest wetest noisiest
vicious thunderstorm moved in there ruined our dinner and we ended up driving out in my big truck I had a big
F-150 or F250 diesel truck and the water was up 3/4 of the way up the tires and
we drove out out of there and drove all the way back to Mesa where we lived and it was a really crazy thunderstorm but
that's where I met David was up there giving a lecture and then my next story
David eventually became one of my customers I'm not going to say anything more about my own software but he became
one of my customers and I ended up down at his house in Veil visiting he Wendy and
Carolyn Shoemaker and we ended up out in David's
Observatory Carolyn was working his 16inch me Schmid camera with film in it
and manually guiding with the handbox she had a guide scope she was staring
into the guide scope and guiding these long exposures to film and I remember
her saying I put that in the fridge what
want to bring one of my what am I hearing I
[Music] have I don't think that's me what what hey
John can somebody mute him I did okay so
um anyway winding rewind just a little bit
and in her soft voice Carolyn mumbled and I remember this I so love doing this
and she's sitting there guiding to that with that scope it was enchanting and so I had a chance to meet
Carolyn I met David I met Jim Scotty who was a key person in my getting into uh
astronomy so all of you thank you Jim's still around of course
doid so that's just an aside what I wanted to do
tonight for the rest of my presentation is talk a little bit about what I've been working on along with two other
colleagues Peter Simpson and Daniel van Nord we're trying to make things move on
from you may have heard of ascom it's a universal uh protocol and technology for
connecting applications like you know um nenina s
SVG ACP all all the astronomy programs
connecting those to the instruments the focusers the telescopes and it's done in
a way that is a universal connect so anyone who's writing an application can
write to one universal interface and then address any of the telescopes out
there but it's a Windows technology it started 20 years ago so a few years ago
we decided to go for the next generation of that and that evolved as standards do
over a period of a few years but I want to share with you the primary nothing
really technical about it but just the primary objectiv so let me um uh share
that screen with you which is
this are you able to see this yes website here okay yes and if you want to
go there you you can go tow. ascom alpa.org so it's the next
generation of ascom and what we try to do is
solve the biggest problems with astronomy connectivity which is is a connectivity another Universal
connectivity technology and again I'm not going to get into the blood and guts of it
but the biggest problem if you if you read through you know cloudy nights
anywhere anywhere you'll find one after another after another thread that starts
out I can't get XYZ software to work every time I push this button or it's
it's acting weird or whatever well did you check the ascom platform did you update Windows what the heck you know
this that or the other and it'll go on and on and on on and on and it all it
very often ends with oh I changed my USB cable and that fixed it or I changed my
USB hub that fixed it so USB connectivity is probably the biggest
source of pain for astronomy technology out there so what would one of our uh
objectives is to eliminate USB how do we do that I'll tell you the other thing is
if it's not USB well I got this ascom driver from Joe Schmo and Boulder Creek
um California and he tried to make this work with the vble feter focuser but it only works part of the time and the
driver you know or I don't have the right driver and especially with cameras which one should I use blah blah and the
the ascom drivers are a pain in the neck often times and when they work it's
great but there are some that aren't all that well developed or created and they're
problematic they have quirks things like that so that's another
pothole so what we tried to do is create a new standard that eliminates both of
those things that's the end game now there's steps leading up to it and again I'm going to stay away from the
technology the technological progression from the old to the new I just want to
tell you where where we want it to be in the long run and that
is self-contained devices that sit out there and all by
themselves they speak a universal protocol that the application can talk
straight to over a network connection not USB so an application I I don't want
to favor any particular one so I'll just say like nenina or SGP or ACP or a sharp
cap I don't there's a lot of them out there those apps would talk not to an
ascom driver which then uses USB to connect to the gizwiz they would talk
via a very well-known not Hightech very well-known
Network protocol directly to the device and I'm going to show you some examples of that in a
minute and the app here can you see my um my mouse here
uh yes it's yes yeah I'm I'm waving it around here on the on-ramp for astronomy
apps an app can talk to a self-contained device by virtue of the probably
well-known Chooser it happens to have extra stuff in it now that will connect
an existing ascom speaking application on Windows such as Nina SGP whatever it
will connect directly to one of these networked alpaca devices no driver no
USB okay and then the flip side of that is if you have a device that has an
ascom driver on Windows an application and I'll show you a few that speaks
alpaca can talk to that ascom device without them having to modify it so
basically we provided an on-ramp from a
an app like that exists today and doesn't need to be modified you can talk to the newer as packet devices without
having to change the app eventually we hope they will but we provided a bridge
that way and we provided a bridge the other direction which will make any ascom
device have an alpaca personality so an alpaca speaking app can talk to it so we
we've tried to create things both ways and that second thing is called ascom remote so let me show you a few things
that are out there now that already exist the boltwood cloud sensor is
driverless self-contained it's the old boltwood Cloud sensor but instead of having a
driver in USB it has its own built-in alpaca network interface so anything
that speaks an ascom observing conditions and safety monitor can use
that at Chooser and find that it'll Discover it out on the network and connect it up and without changing
anything in the app you can now use this new Cloud sensor Pegasus has pretty much gone all
in for alpaca the I'll show you a couple of things right now that are
self-contained driverless and ethernet and Wi-Fi that you don't need a driver
and you don't need USB you talk it again using the Chooser interface that I showed you you can talk straight to this
Pegasus Rotator and um it's you know it just works so that's pretty cool the
people at dark dragons have gone all in on alpaca they have several devices this
is a rolloff roof controller and it it uses the standard ascom or alpaca
interface to control it and you can talk to it from any Windows app but it's it's
self-contained and it's driverless and it uses ethernet Sky Safari on uh the
iPad has alpaca built in so this is the flip side now if you have for example an
explore scientific has an ascom driver for their telescopes Sky Safari doesn't
need any dongle or any adapter nothing it has alpaca built-in by firing up and
the ascom remote adapter the on ramp I showed you Sky Safari can control the
explore scientific um mounts with no dongles and
no drivers and nothing like that well there's a driver I'm sorry that's incorrect the the Explorer Mount has to
have does have an ascom driver on windows so that but the ascom remote
program puts an alpaca front end on that and Sky Safari can talk to that directly
we I don't know if you've heard of these people this is uh uh Observatory Tech
observator Al s in Chile they have 120 telescopes up
there and their Weather Service they took the driver software development kit
that we just did with um python you don't need to use the windows C the python kit they plugged it put put it on
their Linux system and offered alpaca observing conditions and
um uh safety Monitor and all of the Windows apps that are out there can talk
to this and it solved a huge problem that they had with Distributing weather and they were able to develop that
special interface in Python in two days the guys up there are really sharp
that's all it took them from when I told them about the s CK 2 days later they
said we have it working and right after that a customer of mine that put us
together on this deal said yeah I'm I'm plugged into it now and it's working great so that's a pretty big um Victory
there Patrick chial has a uh a program sky chart and
cartel it speaks native alpaca so any of those things that I showed you that
speak native alpaca the self-contained driverless this program can talk to
without any Windows involvement at all but it can also talk to telescopes that are hosted on Windows through the ascom
remote on RAM so that's there here's another Pegasus Device that speaks um
alpaca self-contained driverless ethernet and Wi-Fi the people at dark dragons wrote
an app for the iPad that speaks alpaca and and um
has the cover calibrator interface so if your software the app knows
about flip flats and all the other stuff that speak cover calibrator on
ascom this thing speaks alpaca and you can talk to it through the Chooser I
showed you the other direction and it becomes a flat panel it turns your iPad into a variable brightness flat panel
and what they found to their surprise is the displays on these flat panels are very good for producing light for taking
Flats so that's a cool idea in it no dongle no drivers driverless no USB all
over the network using alpaca here's another app that speaks
native alpaca that can of course use any Windows hosted um uh uh
devices by virtue of the ascom remote onramp that goes the other direction
again those programs don't have to be I mean those devices don't have to speak native alpaca we hope they'll eventually
go that way but they have a bridge so that they're usable right now all of of
of um uh the optech devices speak alpaca Daniel
van Nord is their engineer and he's one of the three guys that are the my colleagues in doing all of this act
activity and he has done some amazing work I'm again I don't have the time or
it's probably the wrong audience to go into the technical details but and Peter Simpson and he are the other two primary
my two primary colleagues on this they do most of the heavy lifting nowadays actually
Cel CCD I should mention cameras can speak alpaca as well and Peter Simpson
developed a high-speed image transfer protocol that goes along with it so it is actually practical it's not as fast
as you know uh the triple whizbang USB I
don't know what but that has to go straight into memory and all that but it's plenty fast for most uses it will
not one thing alom does not have is video the high-speed you know multiframes per second we don't have a a
format for that or an interface for that but for capturing stere images like like this this software can use an uh ascom
speaking camera via the on-ramp or if a camera wanted to become
self-contained driverless it would speak to that this is a whole alpaca based
Observatory system I don't have the time to go through all of it but any and if you go to this website when you click
this any of these images you'll go straight to the uh let me just do that's
kind of not this right straight to the actual website for that
so another Dragon Light this will also control a panel for flat lights that's
kind of like the iPad thing I showed you Han Klein built a sky simulator which is
a simulated camera that you can speak to with alpaca and last but not least um I
developed a uh python package so that if you want to write a program to speak to any pack a device control a telescope or
focuser or both or whatever you can import this and it makes everything really simple one or TW line calls so
for example uh simple well I don't know I should just quick start here to talk
to a telescope you know this is mostly print statements here and you can run this and
slew a telescope and that's as simple as it gets so you don't have to think about
any of the network stuff or any of that it's all abstracted so that pretty much shows you
the Showcase if you click Tech it will take you to a more technical uh much
deeper um informative thing about alpaca and how you can you know the various ways
that it can be uh applied and all of the
Gory details of it and finally for talk
we have a forum that will um where you can join and talk about it and ask questions and
so forth there's also a developer side of this that uh if you want to develop
that group is the driver and application development support Forum so that's about it and about
will'll take you to the main ascom website which there's more information than you probably would ever want to
know about I haven't been paying attention I don't think I've gone over 15 minutes in fact I might be able to
help Scott recover a little bit of the time that's been lost I think that is
about as deep as I should or can go without getting into a whole another
level so um
I I don't think it's we can take a Q&A or if if somebody has one or two
questions that they want to put up on the uh on the I've got the the YouTube
says you're you're his hero so who does oh Jeff Weiss oh yeah he's one of the
dark dragons guys okay all right yeah there you go and I have a question right away sure more of a comment than a
question when you first came out to our site I'll never forget this you are
sitting out in the observatory with me and uh Carolyn was there and Wendy came
out and you said I'm not here to teach you how to use ACP which was the uh
which was and is the software you've developed you said I'm here to teach Wendy how to use
it about this to use it and you said yes and you did
and night we've been friends ever since well that was a wonderful visit it
something I will never ever forget and I will never forget your wonderful presentation tonight it was worth
staying late for well thank you very much David I really appreciate
it so there is a that I should question oh you can see him Scott you you can um
tell me what yeah this is Joey Troy he's watching on YouTube and he says how does
alpaca um how does Al pack deal deal with the raspberry pip is connected to
an RPI sending data um Joey I developed
the both the SDK which I didn't show you about the software development kit for
alpaca in Python and also the Alpa client Library kit which you can
use to write python programs to speak to alpaca devices both of those were developed on our Raspberry
Pi so it's fine I I actually ran Visual
Studio code on the Raspberry Pi tested did the all of the unit testing for
Alpa and yeah it's slowish and it this is a Raspberry Pi 4B running the Bulldog
64 64-bit bulldog and I didn't have a
you know it would just ran I mean it was that's I I haven't yet put it into the uh
public Outreach website I showed you all but there's a a program a produ pro
project that just popped up on cloudy nights a few days ago where a
guy has put an entire focuser with alpaca the whole protocol stack on an
esp32 which I just think is amazing he did it in C++ and that's a you know
that's a tiny little chip um really kind of like pre pdp1 almost so uh that
that's pretty cool I I I wish I could bring it up well anyway I'm not sure I
can find it uh on um cloudy nights it's it might not be that easy I'm
trying to find it right now but no it's in fact cloudy night is dogging now so
never mind anyway that's the answer to that um it I don't know what Wi-Fi 6 it
doesn't matter what Wi-Fi this is all just plain tcpip networking so Wi-Fi 012
3 4 5 62 whatever um I did have one question in a in a
previous appearance that I had where somebody asked if more than one thing can be on Wi-Fi at once I hope that
doesn't that that just I couldn't even I didn't even know what to say with that because everyone in their house has
usually a bunch of stuff on Wi-Fi right so that's not the issue um let's
see that's it anyway I don't I think Joey Troy he just
wrote me today or yesterday for other information I pointed him to some stuff so I recognize the name so anyway I
think I've covered this and um I wish I could find this but I canot
find it right now it's up here somewhere probably forums Astro
photo I'm looking in at cloudy night astronomy software and computers and I know it's in here but I'm just flaming
out because I'm under pressure and I can't find the it says esp32 and alpaca
in it but that I don't know oh there it is Boom all right so I'll share that
with you this just came up uh if I have time am I running over time
Scott we're generally running over time but I would say no okay this won't take
but a few seconds this is what just came up today and that
is past I I I just almost pass the alpaca conform test that's pretty close
so here's his setup um file F page that the es this is
from an esp32 I don't know if you're some of you probably aren't familiar with them but they're extremely cheap
very small weak little chip things that and he's got the whole thing working
here's that's I think that's what that thing looks like and there it is and
it's just amazing that he got the whole alpaca protocol stack and the setup
forms working on it so this this is you know there's a lot of progress
coming does that work with uh that's a complete wireless system in tandem with
your focuser so you control everything at the keyboard well or or on your little
computer you you speak this thing would would be embedded in the focuser there be no keyboard or anything
like that on the focus correct you'd have this is why his thing is
driverless USB Wi-Fi and so from Nina for example and I
only want to use that because as far as I know it's by far the most popular out there just because it's free right so
from Nina you would this thing would be running
somewhere on your network on your Wi-Fi or whatever from Nina you'd bring up the Chooser you'd find this thing it the the
Chooser would find this focuser and give you you know my fancy alpaca focuser
you'd click that bang it creates a bridge from ascom to alpaca and you now
can use that from Nina without having without the Nina people having to put actual alpaca code
inside Nina I I'm hoping that these people will include it and the ascom
platform has all the alpaca support in their libraries so the heavy liftings
already been done for the application program is at that end and we're just hoping they'll follow up and we're just
trying to create Demand with that public Outreach site that I showed you we're
trying to create demand from people from astronomers that this is out there and
you need to talk to your suppliers and tell them this is what you want we want to get rid of USB and we want to get rid
of drivers and that's what we're trying to do that's right that I mean the
manufacturers do listen to the customers so that's where it comes from they don't
listen to us you guys are just making our lives on that's right the less you have to do
the better you know right nobody wants to do anything unless there's a you know
unless it's going to help their customers do things better and put them in a better position as a result of it
and so that's what that's the right approach
amazing today what we have compared to the original people who started out the
tools are getting better and better every incredible monthly incredible and part of the
reason that that's the case is that they can focus the people writing the applications can focus on their
applications and not have to write special code for every Mount out there
can you imagine a new mount comes up on the market next week oh no it speaks boo
blop pound sign hash this that and the other we got to go put more code in our
app to handle this new Mount that doesn't act like anything else or Worse something and sorry Scott
but this is one of the biggest pains in the neck is something that says they're lx200
compatible all right and that's like if you if any of you remember the hay modem
Pro yeah yeah so that's the same level
stupidity well Bob I'm pretty sure those that are watching this is the most interesting part of tonight's uh Global
star party because everyone wants to know how to get the gear working and you
know a lot of folks spend a lot of time why doesn't my stuff connect and you've given some insight into why it connects
why it doesn't so that's right hopefully you'll be able I'll speak for Scott and all the rest of us um hopefully you'll
be able to come back on the show and share a little more uh whatever other info
you people nowadays want to keep this up yes for
sure that's what that public Outreach um site is for is to give alert people that
we've been working for years to try to solve these problems but it's going to take action on the part of the people
who write the software and the people who build the devices to use this technology to make that come true we
can't do it all ourselves that's right takes the whole whole
Community okay well Bob thank you so much and uh you're most welcome yeah Maxi is uh in Argentina and it's getting
late over there so we're going to let him jump in for about five minutes and uh uh share his latest images Maxi
thanks for coming on thank you thank you guys sorry it's
late here so tomorrow I have to work but thank you for giving me this five minutes to give a little short percent
of what I've been doing this couple days ago uh I was practicing again with
planetary pictures of Jupiter and like I said before I was trying to capture
Europa Moon passing ER by in the back of Hub there so let me share my screen
um here okay do you see it
yes great it's going to be the third anniversary from of this Eclipse a
couple in two days CES uh well like I said like I say um I
was doing videos of hiter and you can see there's a lot of videos here
ER 121 videos of one minute of Cs one
minute each other of two hours almost capturing so I only work with the first
is the thir 30 is first and the result
of what I get of this capture was uh this image that you
can see there's a lot of details of the storms on Jupiter and the equatorial
bands and uh here this
shiny circle is Europa in almost
passing behind Hub there it's so it's going to
be anation but then more later will be appear almost from here because today
just G was talking about the shadows of ganim but in this case was in Europa so
when it was all this direction uh in almost here will we going to appear
again because the shadow of hiter was covering up so Days Later ER
last Friday night I think no uh yeah Friday night I brought my um equipment
to a rural ER place I went off my work
came here to my house and then I put my equipment little equipment but travel
almost five 50 kilometers H I was almost
here yeah I think it was there so so H I have almost H the North and the
equatorial um sorry the the equatorial ER line ER without light
pollution so I give a chance a lot of objects the play is before that androma
but H when I saw the I don't like the the capture that it gets I say okay I
want to capture the three maras or maras or the oran belt and of course in the FI
of view you can see uh here's the hor horse H nebula the flame nebula
minaka alaki Anam stars but also there's
a lot of clouds little clouds there so when I process this H for the first time
I get this result let
me ER rotate this
okay and there's a lot of colors and
details that came up from one single pictures
of a was 1 hour and a half taking picture of 1 minute but a couple minutes
ago I reprocessed this H sorry that's my phone I have the the
SAR of the submarine I process this again and I like it more because I get more high
contrast than the another one and this is the oneon-one
ER field of view and I really love to capture this and I
did this because thank you Scot and I did this
because a in a couple days it going to be the the anniversary of the World Cup
win of Argentina my country so in our
[Music] um Shield schol I don't how to say in
English in our t-shirts of the national team we have two stars so now winning
this workup we have three stars in in the signature of our team so
representing that we have the these three stars minaka Alam alitak so they
represent the the three World Cup Championship that arent Argentina one so
well for now this is all for today h thank you for and I'm sorry for be
shortly H but I hope that you like it and well and of course thank you for inviting me Scott and guys it's good to
see you again yeah yes and uh and yeah then uh special thanks to um to Daniel
Higgins who conceded a few minutes here so
okay all right so uh up next is uh Daniel Higgins and he is going to give
us a wrap up of the astop paloa event how did it go um can you hear me yeah
okay good hear you just fine yes awesome um it was it was awesome but before I
even before I even start with that um I think i' i''d be remiss to say that um
yesterday um a member of ashworld uh passed away
yesterday um very sorry to hear that a a member friend of mine uh and you may
know him his name is uh Nigel Arnold and uh he ran Hogarth astrophotography on
YouTube for quite a while um and I'm gonna put a slide up in a little bit but
um Luca Maro uh from um uh what's Luke
Arnold I'm sorry Luke newold from lucaa started a GoFundMe page to get donations
together for cancer research in the UK um so if anybody's interested just uh
hit up the G GoFundMe page and uh you know maybe we could do some good for
cancer research so anyway that being
said um um as for Pala was awesome it was really good we had 13
guests um and uh including yourself Scott uh we had actually you know since
I got I'll share my scheme real screen really quick um and where is let me see one second
get R of that get rid of that and then we'll
do sp okay and then quick play there we go
all right um so that's the uh Nigel Arnold slide that I have so um if you're
interested into um donating to cancer research in the UK in memory of Nigel uh
feel free to hit the Gund me page there and um and uh we could uh do some good
for some some people so um but Astro plua was was December 9th uh which was
wow was three days ago already gezz what just time how time flies huh yeah I mean
so we had some major major guests Trevor Jones Dylan o'donell Sean neelsen
unfortunately had to go to his wife's birthday party so he wasn't I guess he
forgot about it and then he remembered so uh don't forget the birthday party he
had to he had to go do his thing um Astro stay Stacy dton uh you Scott
Roberts Ms of picks Insight Charles Bracken um uh Dr SASS and we also had
phelip from Primal luche lab we had a recorded video from him in uh in Italy
and um Tom and Clark and Omar all from Primal Lucha lab and Wayne Parker um so
it was really really really really a great event it actually ended on time um
but um you know shocking and as it may seem it's so tough to run these things on time when you're doing live but um
hey it was a lot it was a lot of fun it was eight hours we did a lot of great giveaways and if we have a second you
know maybe we could talk a little bit about Cosmos in the classroom in a minute but just really quick um if you
want to see any of the guests coming up in January because we're starting to book up and uh Bob we're gonna have you
back on and talk about alpaca again but um January 10th we got Nico Carver
coming in from nebula photos um Maxi just told me he may have to um
reschedule but right now he's just is on the 17th Adrien Bradley on the
25th and then we're going to be having mabula hcom from astop pixel pixel
processor upon the release of AP 2.0 so uh that's going to be a lot of fun so we
got some guests coming on board yeah and uh starting to book them up again so
yeah it's gonna be a lot of fun the viewers just learn a lot on these programs I mean you are you you're
really um sharing all the U fine details of of some of these um uh processes and
techniques and uh um so you know you undoubtedly have some uh
incredible success stories do many beginners watch Astra World TV yes so on
um on Friday nights we actually gear our night towards the newbies kind of and um
and what we do we usually started off with a A constellation we do a north and a South so not to offend people like our
buddy Maxi and Caesar who are down in the South so um so we do one in the
north and one in the South and it's really geared toward as for photography so so I'll do one and emic will do one
and we flipflop every week saying okay you know what um we did we did Pavo last
week in the South and we did I think uh Lyra in the north we try and do it at
the at the time where things are kind of of um in the sky you know and relevant
and we pick a couple of targets and we throw them at that and we also do a little mythology kind of uh uh history
kind of thing on how the constellation became a constellation that's fun yeah
yeah yeah I wonder about that sometimes you know I'm sure there was some
psychotropic things involved in some of these it was it was called pipe rust back then
um and uh they actually got it from drinking water and they just all got
high from water from water yeah when they when when they didn't figure out about pipes rusting and they started
doing pipes made out of rusting metal yeah oh yeah wasn't good it wasn't good
so but um hey you know you know but it's it's a lot ofun we do we do a lot of and
some of the stories that the we we really probably geared towards either Arabic or Greek mythology and sometimes
a little Roman um but um it's it's really cool some of the stories out there regarding like cedus and and all
all the all the uh Herculean and the drama that's in some of it too oh it's
crazy right it's it's a lot of fun though but um very cool very cool well
great well thank you for coming on thanks for having me on it was a lot of fun and uh um you know uh we'll uh we'll
have to uh participate at a future astop paloa so so and and you know I'm gonna
have to drag you to starmus you need to go you where where is that starmus it's
it's in Slovakia I thought it was out there yeah yeah yeah yeah yeah so you just got to get your passport ready and
and uh fly I got a passport that's not a problem all right so you fly into Vienna
okay and uh it's a it's about I think it's a 50 minute ride from Vienna no
problem my wife would love it yeah yeah yeah if you like you like music you
like you know astronomy and science you got you're gonna love this well I've been threatening everybody on AST world
for years on getting Brian May to come on and I been pummeling his like agent
for like two years I like the guy from from um what was it sha Shanker Shank
Redemption sending a letter a week until they gave him what he wanted a week until something happens so pretty soon
it's gonna fall Dave I'm gonna go to Dave AER and I'm gonna start pummeling him his email
so right but well good um well thank you
so much and and just real quick the next time I come on maybe next week I know
we're running late in time already so maybe next week we talk about uh Cosmos in the classroom well we let's just take
a minute right now okay uh Cosmos in the classroom is a project that uh kind of
was born out of a u a donation that we gave at staris in while we were in
Armenia and uh I went to uh you know I told uh you know the organizer Garrick
is israelian I said you know I'm going to donate a a 10-in telescope uh uh to
the starus uh group and H how do you want to give it away and uh he came up
with the idea he says well he said let's give it away to a school and um so that
really got my gears turning because you know for years I have heard uh you know
people complain in astronomy clubs about the graying of the hobby you know and uh
here here here I am getting gray okay uh I
never complained about the graying of the hobby because Galileo started his hobby when he was 45 okay so
right and he gave some of the first star parties and stuff so it is kind of a uh that's about the right age to start
serious amateur astronomy I think you know but it is very important to educate
and expose young people to science yeah because we don't know where it's going to take them we don't know you know
they've got big problems in their generation that they're going to have to deal with you know they've got our baggage that we've we've handed them and
uh and they've got they they need uh in many cases a brilliant solution you know
and um and that those Brilliant Solutions are going to come from methods of Science and so an introduction to the
root of all Sciences astronomy that's a great way to go and it's so accessible
it's it is the gateway to Scientific literacy and uh so um so final frontier
absolutely that's right and so um you know Garrick uh uh arranged for me to
give this telescope away to a local school in yavan Armenia and and the
school just I mean the Fanfare of this was just off the hook I mean there was
uh the the Ministry of Education was there uh U people from I think Congress
were there uh um and uh you know all of the the high school students they were
lined up on both sides of the road leading up to the front door of the school singing songs from the school you
know and uh and their native language and everything it was beautiful uh and
we ended up signing the telescope and giving it away to uh and but more
importantly it was given to a school uh with a
educator that would sustain the program you know because and we Dan you and I
talked about this you know so many Scopes end up in closets not just with
amateur astronomers and families but with schools and universities and stuff there's got to be thousands of
telescopes that are kind of collecting dust somewhere absolutely and they should be looking at the stars
so um but uh we we we felt that uh
donating to the school was a very effective means of getting people young people exposed to science uh and and to
astronomy and so uh that is the cosmos in the classroom idea Dan
uh uh immed immediately uh uh you know connected with with me on this idea and
uh so um you know we are out there looking you're out there looking for a
uh worthy school um and a worthy place to give this telescope away so that is
our Cosmos in the classroom idea and uh um you know you're the first one to do
it in the United States yeah so so if anybody out there that's watching us now
that wants their school to be even selected or or or or you know want to
request it uh feel free to hit me up on my email at danastor telescopes.com and uh we'll
start a conversation so there's going to be a lot of people involved only one is giving away so I mean uh you know hit me
up on email but it should I remember I remember us talking a little bit about
this idea and it's cool to see that you and have actually got some attraction so
yes so Dan um I may be giving you a call I need to talk to all of the astronomy
organizations that we've got here in Michigan Southeast Michigan and um see
if there may be some candidates for for doing this sort of thing I know we we
have the uh we do the giveaways at some of our star parties we do the um the
telescopes and we've got uh one of my clubs you know gets
donations um to give away but then in ASI a for instance went to a gentleman
and he came up and told me he wasn't sure what it was or what he was going to use it for yeah and um you know it's a
prime example of getting this gear into younger hands and then teaching how to
use it um right is definitely something that needs to be done the the the format
of of uh donating a telescope to a star party or uh to a club for their annual
banquet or something like that it it's exciting okay but often the winners
already have telescopes yeah and they already have gear all right and uh very
true right so
Dan you have some gear right yeah so uh let's get it out to the schools to the
kids to Youth and uh uh you know uh change some things here
so very excited about it yeah very excited and it's really got to be a
school that's actually gonna you know like Scott said maintain the program
because you know there's too many times and too many telescopes and even I personally have given Scopes to schools
that and and it was my own school and yeah ouch yeah and I was I gave him a
tell I want to donate this to the school oh great we need this we have a great they did nothing with it at all it's
probably you know like it's kind of like you know it reminds me of remember the basement in The Breakfast Club where the
guys going through the files and everything and trying to find out stuff on the teachers probably stuck in a
corner of that room in the basement behind the filing cabinet yeah yeah yeah
or maybe in the filing cabinet depending how big it was right yeah but I'm super
excited about it Scott thank you so much for having me on appreciate it and um if anybody knows anybody hit me up and
donate to the Gund me for for Nigel so great okay right that's great okay so um
uh so up next um who is up next we're going to skip the 10-minute break here
and marchello Souza is up next
marello there he is you're muted right now
marello okay I'm here I want to change this effect to hear that I don't know
what is here we go okay I'm back
hi thank you for the invitation thank you thank you very much
so um marchello I know that we're getting close to having another issue of Sky up magazine and uh you could
certainly talk about that but does Brazil have impact craters in in your
country we we have as blams yeah
but we have C around and the inside then only because
you have part of Brazil you have Forest rainforest in Amazon then they found
they found some as blams there but you have Forest then we can they can't
analyze anything that and also we have here in h Jan I'm
trying to change this I don't know what I did with I don't know how to
sayange Jan they found as blam here also
in the in the H Urban
region and is very difficult to do anything here because you have a lot of
people living there heavy seats then we don't have one big Crow
that like in Arizon that you have in Arizona United States in other count
here we don't have this it's very different from H what you have in other countes we
have a few also meteorites found well here in Brazil well yeah the guy saw a
meteorite fall and is yes but it's something that very difficult to happen
here because is I I I have a history about this we we
received the information I think that before the pmic 2018 2019 before the pmic H once one the
most Village here H they saw H bite okay and the
mirrors the mirrors on the Windows of the house
they have explosion and the window of the house begin to Oh Yeah from the sonic boom yeah because of the Sonic
Boom then we visited the this Village that is I think that's two hours from
from here where I live here in compus it's not so far one hour and a half
maybe and because the road is not good the roads then and it don't have asphal
in part of the road then we visited the place and you know the difficult to find
something there because you have the small village and they Forest
around then only if someone saw something falling in on the floor or
in was in the urban place that was very small place it's very difficult to find
it's very difficult to find something like this when you have Forest because
you have here big trees and the in the soil in the so you have leaves a lot of
leaves then it's very difficult to find some something there we tried we tried
during two days to find something but we didn't find then these uh kinds of
history that we have here I try in many I visited many place that people said
that they saw H probably a hawk that looks like a metor right I see many here
but generally they are not meteorites I'll share my screen here I
want to show something it'll be not long presentation and let me see today I
think ah sorry a moment I need to do this is a a old picture but before I
share I learned that uh share sounds because I show something that it was a
big impact for me nice song do you remember this
picture I found this picture I think
that John schw that's here I don't think because I think that's when I I was in
in United States in the event that you organized yes this was a a Starlight
Festival that's right yes I found yes this I found this Pi because I
was looking for old Ma I found this we organized an event last week to see
Jupiter and V and Saturn Saturn they are fantastic next year I
think that will not be possible to see the Rings then we need we need to to
organize it until when is possible the observation of sat D now I have a
partnership with Nazo that's Nepal astronomy societ
astronomic Society we develop begin to develop project together and this is the
day where the sun was overhead here the
and you can see you don't have shadows here in the S right moment just behind me below me
here you see the the shadow then reorganize an event to show
for the population
this
for
this was an event that you organized this day and the other day we had this
now the the rainbow that double rainbow
double rbow yes the second one you have the inverted colors in relation of the first is is
this the same mall where you have the um uh you were hosting the star parties
during the pandemic yes yes yeah yeah the same
shopping where we organizing the the drivein yeah was great that was a
wonderful idea yeah yeah and I I I don't know if I said here the shopping
received the prize for this they were selected for the second best event of
all Brazilian shopping centers yeah I I I'm sure it was I'm sure it was and the
first time that a scientific project received this prize in a shopping
center and here it was the picture from me that that's fantastic that I took you
using a the a telescope from the Observatory that is the H head
nebula and now I two things that I
remember when I talk about impacts for me this was the most fantastic one that
I saw report that cinski m in
Russia yes that's why something fantastic uh
I think that I before and after I
never read a report of an impact like
this and now we know that the the
asteroid right that was responsible for this have had between 17 and 20 20
Metter and the other one that was a fantastic event was
tunguska event that happened in the beginning of the 20th century that was
the I think that's the biggest asteroid that he hit from the beginning of the
20th century until today and this is the video that is
fantastic video I found old videos that show what
happened there I think that's this why very special
moments and the Sonic was big they had so many videos because
all the video cameras inside the cars yes in Russia they have inside the car
and and it happened in a in a moment that you have a lot of cars in the
streets but not in the middle of the night
look at that some finger amazing yeah brighter
than the sun I think that why is the biggest one in
the I think that's sorry I got
[Music] [Applause]
here [Applause]
yeah fore
fore
by some f and they found them the many
meteorites here this is the one of them that they found oh yeah they Fusion
crust on the outside is beautiful that's a beautiful meteor right yeah they found
men there after this and the other one was this impact that I think that didn't
H hit the surface but it
exploded above the surface and it was responsible for one of the biggest
natural explo explosions caused by a
meteorite because ER destroyed millions of trees in Russia in
198 the tuska event there was the biggest one so here many of the Tre
destroyed and they heard the Sonic very far from the place of the
explosion this why the biggest St and we are organizing now H We Begin the
organization of our International Event that happen in April
113 2024 here in our city in Brazil uh everybody is invited to be
here with we'll be after the the eclipse then who can participate to be very
welcome here and now I have a sad news to say
because here I was picture here in Paris in the opening ceremony of the
international year of Tony and with me here we have shat from Nepal and G MAA
and his wife pass away Pascal Dei and
unfortunately he passed away last Friday and he he was a fantastic person
one of the most fantastic person that I have met he he in our city with his wife he
made a fantastic presentation and I organized last year we had a online
program with him and I show the short
parts of this to on know I show these
videos um yeah the most interest I have got as a child I was 10 years old and so
I was very interested in the astronauts they just was walking on the moon for the first time and uh so as all the kids
uh like me they interested in astronomy and uh space uh race and uh so and so on
and so start the first motivation from from the
astronaut yeah and then I I I was interested in in science uh very very
early and we have here in in Europe and Germany and young science
contest and so I started observing eclipses so there was partial
eclipses um from the Sun and uh so I built a telescope and took the first
photos and I was winning um prizes for for my work and so this was the biggest
motivation during this time um it's difficult to to to say uh how many
eclipses uh I've already um saw so it's
about 35 36 total eclipses and a few um
anul eclipses and um lot of partial
eclipses um so my first Eclipse I I told uh you before uh was going to Kenya and
Africa and um one of the the last eclipses um I saw was in
Indonesia I would like to give to the the following Generations but the main thing what I
want to say is uh keep your eyes open and look for
details in the nature uh look to the
stars and not so fast like like today
everything is running keep take time to
observe or just enjoy the
nature and [Music] um how I don't know it's the right word
um eager eager means um excited
yeah so just open the eyes and everything what
you do um this thank you very much for the
invitation SC thank you yeah thank you thank you for thank you for the memory
of gno um he was uh a friend to many uh I met him on a few
occasions uh both here in the states and in Germany and uh uh very gentle soul uh
this guy but uh he and his wife lived a life of adventure uh he showed me um
star parties stargazing events he gave to indigenous African tribes um he really embodied the uh the
the mission and vision of someone that does astronomy Outreach uh to an extreme
degree and uh uh so uh he'll be missed and I was sad to hear um uh as I learned
from you uh marchello and I'm sorry I missed your message from Friday but uh but yeah uh
he is uh he will be missed so thank you thank you very much thank
you okay all right so um up next is um
uh think I'm up next Bradley yes that's right Adrien how are you doing good I um
as always I'm glad to be here this time I'm glad that I was able to participate not only at the beginning
and chop it up with some of the uh the uh first shift but uh as always I'm
always glad to be a part of the uh The Late Shift for those of you watching I will try and Blaze through as a an
imager that primarily works with a DSLR and a tripod um
impacts aren't something that um I typically image unless I'm Imaging the
moon and uh Robert Reeves has already done such a wonderful job explaining the uh various impacts the
names of some of those craters we've given and how those things came to be um
I wanted to think out of the box Scott and I wanted to uh talk about another
type of impact that uh uh hits astronomy especially astronomy
enthusiasts in a way that um stops a lot of astronomers from wanting to go
outside and as I Adrian yeah can I I want to say
something I saw a message that you poting Facebook few days ago
congratulations I think that you are a baseball player is this awesome yes I
played in amateur league in the Hall of Fame and I'm in the Hall of Fame for that League yes I
congratulations congratulations thank you thank you marel I think you
um I think you posted uh to that so so for those that don't know one of my
hobbies is also baseball and um I made it to the hall of fame in one of our
leagues I played for some 20 odd years so astronomers always find something you
can do that you enjoy that'll get you out of the house exercise um hiking is something I've
been I've had an eye on especially with my uh gear um if I want to go somewhere and
take an image um somewhere out in nature hiking to that place is one of the uh one of
the things I've thought of doing now it's not for the faint of heart because like this background picture I have it's
dark out there and you have to be you have to have your flashlight and you
have to be prepared um and keep your wits about you but what I'll do is share
my screen and um here we go as I was mentioning um Cloudy
Skies have often turned around many a
wouldbe visual astronomer imager landscape astronomer landscape
Imaging and doing Widefield gives you an opportunity to
take advantage of the Cloudy Skies one of the reasons that I jumped into doing
more of this Widefield type of Imaging was I saw Beauty in doing landscape
photography combining it with knowledge of astronomy knowing that this is M8 and
M20 as opposed to just seeing this as well it's a part of the Milky Way you
know it's not only composing images but it's composing knowing that this is
Scorpius and that's Sagittarius and actually including these constellations on purpose in images and when an
opportunity like this comes where you've got two things you normally don't see at the same time I like to take those
pictures so it's um let's see
so share um some of the ways that you can
use clouds especially if you're out there and you are a land they call it
landscape astrophotography um or nightscapes as I like to call it um as you can see here
folks are still this is some time ago the um this gentleman right here it's one of
these two gentlemen looking up um this was his house and we'd always come over
and observe and I had just gotten started with a camera um unfortunately whichever one of these two
um men here is named John coslin he had passed away some time ago uh 20 either
2017 or 2018 um and this was his
big uh 24 in t mirror on his uh
dobsonian mounted telescope and uh so observing as long as there are sucker
holes in the sky you could still try and observe and now these it was a St yeah
it was a Star Master I can tell by the bearings yep even in the big city you
can still will get some Imaging done there's stars in the sky uh that was
good enough for me being by a huge town like San Francisco with the fog rolling
in this was one of those nights where the fog was not on the bridge so I could
do a pretty good shot with the uh stars of the sky and the
fog it this would be this is an image that attracts me because I like taking
pictures at night so it it made it a bit of a unique image most of the Golden
Gate Bridge images are done during the day and that's if it's not covered with
fog so here we'll let's start firing through when it's cold and it's wintry
and it's cloudy I still went out and this image ended up being in a calendar
at my job so it it's beautiful you know sometimes the best images are the ones
that recreate what you see in the nights sky and um this is an example of that um
sometimes you just have to shoot in the daytime and you may get an interesting image uh don't be afraid to point your
camera at the Sun but do not do long exposures shut the uh aperture all the
way down fastest uh shutter time you can um and good luck um it's if you if you
luck out you end up with an image like this if you leave it face to facing the
sun too long when it's too high in the sky your sensor will burn
out so here's an example when the Sun Peaks through the clouds you can get an
image like this um depending on what you're shooting for um this is a rock
this is not someone's head in case anyone was wondering taking practice
images you see these holes in the sky and when the holes in the sky are full of stars it gives you a suggestion that
where you are gets pretty dark and you you can't wait to go back there to see it when there's no clouds but you can
practice your compositions and there there I am um sometimes and let's see if I can
move this uh if I can move that yeah you get a
lucky shot with the moon because of the clouds it filters the moon and you can
take a single shot where you've got detail in the moon and you've got
whatever your uh background or your you know whatever the rest of is in the rest
of the scene when it's cold and
when there's uh ice on the lake and
there's Haze in the sky there's clouds there may be ice CIS crystals and you
may have Light Pillars you may get a shot like this in a dist but not like
that that's so yep this was uh this was one of those
where I thought I was done Imaging about an hour wow
before um and hopefully my internet connection holds up an hour before I
took this photo I was I had taken a photo on the street and figured I was
done and then I came here looked in the distance and realized I'd caught Light Pillars and uh this is one of my most
unique images I've taken and it was you know it was because I decided to continue on yeah and I believe the
temperature was somewhere in the 20s yeah so some nighttime Imaging is not
for the faint of heart you bring your camera um those they lasted most of the
night um um there were enough ice crystals in the air that you I pretty much had most
of the night there were there were other lights near me and they shot straight up
in the sky too once the conditions are right every light every man-made light
yeah turns into a light pillar I see and uh it's it's interesting to
see because those lights just shoot straight up into the
sky that's amazing that's like yeah it's a like if you shoot less than ideal
conditions you
get something like that you'll come up with a good name for that this is
moonrise and the beginning of of nautical twilight and this Milky Way
this part of the Milky Way has about one minute and it's going to
dis disappear into this um I've always liked shooting in situations that are a
little different you a lot of folks will think this is the Sun Well I guarantee you when the sun is rising you see
nothing you barely even see the moon um so yeah this is when the moon you and
you take the photo you get kind of an effect as if all of these
things are in the sky at the same time but the Milky Way the moon will begin to
wash the Milky Way out and go before it comes up so uh watching Nature's clock
go and capturing a moment in time when you see evidence of all three at the
same time yeah it's
amazing is you know that despite all the clouds
in the Horizon it doesn't
outshine or wash away you know along with the sun coming up it doesn't
won't that Lighthouse see if this may or may not be the sharpest picture because
it may not Aurora here along with all this arite that I mentioned earlier and even
shade of the Milky Way um we probably won't stay but this is the advantage of coming
back how did a different night and yes those are icicles it's cold in
March beautiful you wear big coat and you wear some gloves and you get really
really excited just by being outside I I tend to run pretty warm when I'm Imaging
it's right it's something could you see those with your
naked eye I've noticed about myself um as I just kind of go through
the yeah barely though wow you could barely see it
um clouds this uh part this martial eclipse look more mysterious something's
coming up and you know what it is there's your favorite shot JN so we'll
go through there you've drawn that let's see how many more of these I get it looks like I'm starting to lose some of
my connectivity sometimes clouds create leading lines for those who like uh you
know Imaging with elements of Photography the clouds might produce some of those elements for you that's a
meteor does look look like as it stre it was a per that stre by that's a meteor for
sure and there's some clouds with storms
again apologies for some of the the uh quality of the images I think it's just
my internet very dark area The Shining of
the Milky Way through these dark clouds can PR close to your eyes view of what
you would see with the Milky Way brought out a little bit
more and then the signis region is much brighter in a dark area and the clouds
here sort of point for where signis is as it sets with the sky glow this is
from a couple of uh a couple of years
ago and so because this is getting fuzzy the um moon
visible but um another I believe this to this uh
this is a an area in Canada where there's um there's
giant Pink buildings or pink lights that are shooting into the sky and this
turned into a light pillar
over head you could see Orion and
then here's a uh closer up shot through
Haze but if it were the clear version you the cats paaw and The Lobster Claw
nebula all the way up here in the north uh the rising of the milk way in March
in April in the northern him is a good time to go after the entire scorpion in
midn Northern latitudes you don't have much time and it doesn't take long for the Milky Way
to over here's another shot but that whole Region's blocked by clouds um I love Imaging on the beach
and you'll see more of those you've got Aurora Milky Way
I think this is a plane this time one of my challenges is can I get Ursa Major
and a Milky Way you know part of the Milky we did we lose your uh
connection I think we might have let's see if he comes
back
it was so cold I think he
froze that's a good one now I'm called over here just from the
blue chili over here now yeah yeah why don't we switch to you for a
little bit here okay yeah I mean his work with those clouds you know when
you're out like was just that look really die hard man he's like he knows
the ingredients yeah it's amazing that he sees that and I I've been blessed too
by seeing some great Cloud you know pictures just getting out and um you
know I'm just so happy to be a part of this there's so many different uh ways
people are presenting and you know I I love the connection with the audience and that they're here
I mean they make it really what this is I mean of course there's great presenters but to be able to share and
have a captive audience that that's big for me what we do it for right it drives
me you know to get my work done it's every week I've got to commit and get
some new work and having that Lull in the action was nice because I was able
to you know get some more work done you a it's helpful trying to bring the aame
you know but anyway poor Adrian I was hoping he had more stuff to
show well he can it I'm coming through okay you're coming through just fine I'm
gonna I think he's signing back on here okay we better we don't want to let's see if
we hey Adrian hey sorry I cut out that's probably a
good time to cut out anyway because I realized I was moving pretty slowly
through my images but bottom line being Cloud should never stop you from coming
up with something creative right and that's why that's the main reason I did
you know and maybe in a future presentation I'll keep going through those slides and uh sure show some of
the other connections that I or the other I'm wanting more you know you know images that I've been able to come up
with wonderful good point and so we I'm
glad you didn't freeze Adrian I was worried it was so cold in that shot I've been out when it's cold like
that it's it's tough to hang in there it's a beautiful picture I've got
CER you get that um got colder images oh man um but uh yeah never be
afraid to go out of cold camera's like it too right go
ahead no I just say the camera prefers colder you know it doesn't yeah cameras
can run a little bit better in the cold you know those the Astro cameras batteries they don't run so good if it's
cameras are cooled right to you know zero so if you're Imaging in
cold yeah I swi I had to switch a battery last time I was out and it
surprised me because I thought it bring extra batteries bring extra
cards and bring extra layers of clothing anything you need to
you you're sort of surviving if you're going to go out to a place like what here this is the Upper Peninsula of
Michigan now there were there were no clouds in the sky on this night and so I had a at the uh Rising Milky Way um if I
get get a chance to do it over again I do it the way I've imaged at uh the OK
at OK Tech star party I try and pull more detail it's still it's a beautiful sky
just to look at and to get your binoculars out and
observe isn't that crazy um I always
I'm sorry I was I was saying about binoculars when you go to border seey
itself as opposed to Ellie watching on YouTube says you I
use m33 of a test if I can see m33 in binoculars I know I've got a decent
Sky that's funny yeah and if your camera doesn't work at least you still have
binoculars that you can you can do visuals work you can you don't have to waste such a beautiful sky yes and if
there's clouds then you have to look through the keyholes in order to see
what you can find well every time I go out
that's uh that's why I go and uh unfortunately Bob for you watching um I
simplified my rig so much just a camera with an intervalometer and a tripod and
a tracker on top of that tripod I can unpack it all in the
backpack and go sometimes though I do use my Explorer scientific Mount if I
want longer exposure in
particular well you your work is absolutely amazing totally amazing
landscape for Widefield all right well we're taking up a lot of
time it's 11:03 on the East Coast John and I think it's time for you to yeah share some of your images your Ellie
Ellie Joe's up at 400 am in London you know the English they're tough man
they're they're proud people good people passion but anyway so I want to make
mine quicker take I've got a lot of ground to cover of course you know but
what I was going to do is um always start out you know on topic want
to do this uh on topic you know yep
so I love how it's backwards you start out you put it in and you just go
backwards to move forward but yeah you know I was thinking
uh last week you know how exciting it is for me
to do this and and to have people actually looking at my work and and being intrigued by
the process you know I wish people would um make some requests while I'm doing
the drawing stuff because I could maybe do a request if somebody would like to
give me a shout out some object maybe I could sketch that up group here can and
um bring it NE for next time we could uh present the sketch sure
you know because really you guys are the reason we get to do this this is so
great because we can do our hobby uh straight from
home so I'm I'm excited about that okay here we
go so of course the topic is
impacts you know just imagine you're out in space minding your own business you
know stuff's we're just hanging out
safely then you need to start to worry because you know there's a couple
asteroids that are in question uh apotheus Greek for
Destroyer it's a good name you know yeah because that's quite a big um bigger all
images of apus right there they are from I believe this year so it's it has
another close approach and then 2029 and if it goes through that 600
mile wide Keyhole yeah there could be something to worry about you know I I would say
everybody should just come together and forget about war and making bigger bombs
and stuff and we need to focus on protecting the race and stop these
things from because you know look at the dinosaurs so this is actually I took
that radar picture and and I put it in my painting of apotheus you know
cruising by Earth which is not a good thing because when it hits boom that's what happens on
such a large scale I mean when you think about bombs there's nothing that mother
nature can throw that's so many times more deadly and just on a
scale that's unimaginable you know and then everything's liquefied for quite some
time it's like a nuclear winter I guess it impacts are all over the moon
we have tons of them Archimedes you know when you look at the lro image of this you see the Boulder
Field and these Boulders are like they're bigger than houses they're like
football field siiz Boulders and just the force on that impact they were like
pebbles just scattered out like they were
nothing this the Terminator again we're so lucky were beyond that impact stage
you know the stage of accretion when the planets were forming it was chaos just
absolute destruction uh to be witnessing that if you were here during that time could you
imagine these are all some sketches I've done this was called uh the moon of St
Valentine you know it was just cloudy I went outside and I'm like can you
believe this Adrian would love this one it was like a a real breakthrough
shot for me love the Moon
so you know even uh benu that is very good and it's a full
moon thank you Adrian you have a Keen Eye my friend um you know this benu
we to worry about too in 2075 it potentially has a a chance of
impact so they say but hopefully not this was from our other show just
cruising through so now I'll get to some of my work you know I've been working on this Eagle uh it's just such an amazing
thing to be able to see the pillars in your eyepiece uh using a filter being up at
9,000 feet having Coastal Marine layer clouds come in and hanging out with your
buddy with a 32 inch you get some good views and uh this was like this summer
we got these views that I haven't seen of this caliber that was a warm and cool I like
to do a little bit of each you know to try different feels with warm and cool
just it gives you a different effect just the smallest hint of color that you
see uh some of it's attributed to the filter that you're using usually blows
out the stars but um you know use different filters and your your clear
eye view the nebulosity really comes out when you use the
filters this was another version of my Eagle you know I was proud of this because my scope is extremely sharp and
um to get this kind of resolution from Earth of uh you know the pillars it just
really very proud of this um which you know if I start to do astrophotography I
think I'm G to have a lot of fun with the big dob um using the Rotator and
hopefully some plate solving maybe but this was just a um creation I did based
on Marco's image with his 32 and my 28 was so sharp that I put mine in the
center he didn't like that he he called me Frankenstein said I destroyed his
image but I mean I thought it was cool I was just trying to an amazing isn't that
amazing that we can see like this create this from here you know I mean it's just
mindblowing that we can do this with all the the stuff everyone was talking about
tonight making it easy I mean it's not easy to do to get the real good results
but I think it's gonna probably be getting a lot easier in the years to
come this is cool this one I really like that one this was uh NGC
4244 you know I've been a little on edge lately Scott so I've been looking at
Edge ons to relieve the stress that well that might add to your stress you know
being as edgy as it is so yeah you know um as long as they're elongated it's not
as abrupt but this is a very faint um Galaxy it's a near Ursa Major it's an
extremely long Edge on and uh in the bigger scope I had a hint of a dling
which means the seeing was really good you do have a uh a challenge here
and that is to draw the jellyfish oh IC
443 yeah okay there there you go the thrown down dude I hope I can even see
that visually if that what magnitude is that one um
usually I'm a little concerned I don't know what happened dropped half of my presentation but I'm coming right back
just give me a second yeah don't know
how sometimes you get these uh what do they call them when you have unfortunate
circumstances uh this was another Edge on uh this was in Draco 597
cool this is uh NGC 7814 I believe it's
in Pegasus super far super faint um you see
just really that's about as good as you're going to see visually maybe even a little less I did adjust my
levels this is a cool one in idanis it's um below Orion very low Target it's
called Cleopatra ey it's a planetary nebula blown up
star I just kind of remastered it and and posted at cloudy nights I try to
post you know pictures because everybody is showing so much work if you ever get
a chance to go on sketching forums you can see amazing drawings this is a new
version Scott uh my newest Orion yes had years
on this object um such an amazing object to see in your telescope you just when
you see it and the color I mean I DED it down for you know to post in the
Forum because a lot of people don't see as much color you do see pink and green in Orion
sure I could see color in my uh 28 and the dumbbell the
trifid this is just a little different version pretty cool right very cool
that's the trapezium now so this was really cool because you know we stayed
up all night now it's starting to get light out and we start to panic we're like okay what are we gonna look at all
you can look at is globular clusters
open clusters yeah and then you're going to have to go to lunar or planetary but
if you just so happen to have the lumacon 03 gen 3
filter you can actually view um Orion in the daytime well when it's
Twilight and I think we did actually look at it was NGC
7662 the Blue Snowball planetary nebula at 7:05
A.M this was actually you know every time I do this party I get like when I'm
done I'm just so excited and I want to tell people hey I did this amazing you
know star party tonight and um I was just like it was
late so I couldn't really call you know I want to call you Scott but I know you're headed home and it's late so I
just went outside for a minute and yeah looked up and guess what I
saw this is what I saw just an absolute beautiful moon with
the mackerel clouds you know those are like the old sea captains a long time
ago would navigate with the seant and you know the clouds were mackerel they
were like flocks of sheep and they would see the most amazing you know
Vistas this is actually what I was referring to in Adrian's the color you see yeah that amazing spectral Hue of
blue and then the warmer colors yes but you know this is actually a unique
picture this was also that night guess what that is right there
Jupiter oh I've got the moon and Jupiter
together pretty cool right yeah it's not too often yeah the clouds are amazing I I
always see my little buddy in the clouds can you see him yeah I put I always just do a little
bit of some sketching to put him in there because my little buddy's always with me you know now I'm shifting to
things that when I take my dog out on a walk and I've had a rough day or I'm not
happy or it just all melt melts away the second I go outside and I I walk and I
see these clouds and sun spectrum that little spectral I've been seeing
rainbows all the time and I didn't drink the rusty pipe water either but I mean
the clouds there's just so many amazing things you see in the
clouds look at this Cloud it was like translucent but
just amazes me you know
the it's just an honor to be able to try to replicate this was a cell phone
snapshot I I didn't paint this but I mean man of course it's Christmas we've got a
top our tree with Jupiter in the clouds that's an Italian Cyprus that we
have a lot of them here just the moment you know being in the moment look up and
you see this you go man I want to share this with everybody this just so great then you
know as usual I love to do flowers because they're beautiful and it it it connects you it
really shows you you know all these beautiful plants are reaching for the
Sun for life and um they're so colorful and bright
cheerful just amazes me and I I see this stuff and I'm like
in awe so many people forget you just have to take a little time out and um
just take a nice walk or look up and see this stuff because it it just makes you realize
that wow we have one special gift don't
we to see the color and the beautiful glory of the clouds and the plants and
just life is teeming on our planet and uh this is one
I did of my little buddy my little boss can you see
him so again the moon in the clouds I'm sketching this and then I I see my
little buddy staring at me going are we going in
yet just a little more buddy hang in there it's uh to the right it looks like
a flower kind of and that's his head the top of his head and then his paw okay
okay that's my little Bosco I see I put him in a lot of my lunar works because
he's always there with me and you I take him to the mountain with me
now here he is in his element his favorite you know dogs I mean sure this
is when we were strutting like John Travolta we're out strutting in the town
you know getting our exercise in
together there he is with the flowers I mean he loves flowers too I don't think for the smell but
probably because other dogs love him yep he's very very important part of
my life keeps me happy and yeah lets me know that I'm I'm a special friend oh
yeah he has many looks too you know he looks different from all all
angles and that is it all right I hope I didn't go over I'm
sure I did no that's that's okay it's okay we're at the end and uh uh it was
um it was a great um global star party and uh we had International audience as
well as as we always do um but uh the
um jellyfish yeah yeah you got the all right I'm gonna try yeah you have to
look that one up so IC 443 yeah some of those are tough you
know um and which is why it's nice to do a little lter photography have a friend
or get a night vision you know having all this stuff I'm just going to share it with the public anyway because that's
my mission so I'm gonna be bringing some good views um to the public coming up
and and soon hopefully I'll finally get my stuff live on here and and blow this
thing away I want to show you what I can do my drawing's good but you gotta see
some of these you know but there's amazing guys I mean I'm I'm just doing video stuff but right it's
still it's a good tool it's just another tool you know doesn't hurt to have a
little bit of everything you know I collect them just to have them close at
all times you know never know when you've got to reach out or do some
Outreach you know but I'm I'm ready you are ready
you're ready all right well thank you thanks thanks to our audience I we hope
you enjoyed uh the 138th Global star party with the theme of impacts um I
want to thank David Levy for co-hosting our program and uh for giving us Insight
of what it you know what it was like to uh to know uh Jean shoem maker you know
so um so it's uh um we had a broad uh
range of uh topics tonight but somehow they all pulled it together to talk
about the impact and uh you know so maybe you too out in the audience can
think about uh how uh you know how uh you
know you think that uh impacts have shaped your way send it yeah star
Crusader gmail.com sorry Scott all right so we're going to wrap

are your eclipse glasses safe for looking at the sun let's check to see if your eclipse glasses can handle the heat
or if they need to stay inside first off never check your
eclipse glasses with the sun that's a good way to injure your eyes take your E clips glasses and find a bright light
like a lamp or a flashlight hold your Clips glasses up to the light and look through them the light will appear
extremely dim or not appear at all when looking through the glasses for example you should only be able to see the
filament of a light bulb but not the glow surrounding the bulb also if your eclipse glasses have any marks or
scratches on them don't use them if you have older eclipse glasses from a previous Eclipse give them the check to
make sure they haven't been damaged or scratched all safe eclipse glasses will meet the iso 12312 D2 standard it's best
to store eclipse glasses in a safe place where they won't become scratched or punctured remember never look at the sun
without eclipse glasses or a solar filter be safe and happy Sun viewing
