Global Star Party 93

Transcript:

i'm doing my uh presentation we have a few people today that are
actually mobile on the road doing global star party which is totally cool
we got john briggs at durfee high school uh observatory in
fall river massachusetts um john goss is somewhere in virginia
camping okay using a library and uh and then you're
you're driving is that right adrian yep i'm uh hands-free
whoops i should probably be on the steering wheel yep i just got done doing a little bit
of birding ah okay and uh so i'll be i'll be looking to see
just how many blur blurry photos i got i'm pretty sure
my hit rate wasn't so good today i'm sure you got some that are pretty good you're a pretty good photographer
yeah there's uh i know a couple were sharp but i've tried to practice
shooting and not looking down as often because then you miss you miss things that are going on if
you're too busy looking down to see if you got a sharp photo so i am uh working on just working on
setting my settings and trusting them ah right
how's everyone else doing i think everybody else is okay yeah been
fine
we finally got some beautiful weather here and my favorite baseball team has been doing well so i cannot
but is that a yankees hat you have on yes yeah i i can't it's kind of far away
on my screen okay
of course i play baseball and uh the team i'm playing with wears white socks
uniforms so i will be a uh i will be a white sock
for our for amateur baseball this year i'll be catching that's cool
yeah that catching basically utility player um
i played outfield when i was um as i was going through college i played
uh basically uh enter well not interview or baseball but i played uh
municipal baseball it was for those of us who tried to play and decided we weren't washed up yet we
wanted to keep playing a lot of players that come from the college ranks titus
ranks we just keep playing baseball
sounds fun yeah if i'm baseball by day and if it's a clear sky
i try to do a little astronomy by night there you go
um i love these visualizations they're they get better all the time
but can you imagine if you could actually really see one of these events happening yeah it would just be
i know david saw one yeah actually there's only a series of ones
lots of us get to see that one that's true that's true
and david i think you've got some experience with uh watching
watching collisions of that nature a little bit
[Music]
this is a quote from stack the moon is a ball of leftover debris from a cosmic collision that took
place more than four billion years ago a mars-sized asteroid one of the
countless planetesimals that are from frantically churning in our solar system into existence
it hit the infant earth bequeathing it a very large natural satellite that would
be of course our moon yeah but who knows how many events like that
actually happened during the formation of the solar system i'm sure it was really crazy and um
we had one of the speakers that's coming on tonight uh barth uh daniel barth will come on and we were we
had a conversation about um uh you know
the building blocks of life uh nucleotides and
in asteroids that they found i think that they originally found four and but now they
found another two you know so
really compelling the idea that uh that the building blocks of life are all
over the universe you know and just waiting for any planet that will have it you
know so
okay
since the beginning of the space age nasa has explored our solar system bringing back unprecedented scientific
knowledge but only a handful of these missions over the past 50 years have actually
collected and returned samples from these far-off places
astronauts on the apollo program traveled to our moon bringing back over 800 pounds of moon rock
stardust was an unmanned mission that collected samples from the coma of comet built ii before returning them to earth
for in-depth scientific study osiris-rex is the most recently funded sample return mission that will launch in 2016
and return surface samples from an asteroid in 2023 the comet nucleus sample return mission
will collect subsurface samples from a comet and return them to earth comets and asteroids are leftover
remnants from the early solar system and by studying samples from these objects we can learn more about the formation of
our solar system and may find clues to the origin of life on earth collecting a sample from a comet is a
challenging feat for many reasons including how far away they are from earth and how little gravity they
provide in our concept harpoons are used to collect and retrieve samples from interesting locations on these exotic
objects traditionally when collecting samples on earth we use scoops shovels or coring
drills but on comets and asteroids there's so little gravity that you would push yourself off the surface if you use
one of these methods harpoons allow you to grapple to the surface while taking a sample allowing rapid sample collection
and retrieval first we choose a specific interesting area to take a sample from and then fire
a sample collecting harpoon into that spot as the harpoon penetrates into the comet it fills its inner sample
cartridge with subsurface material as it goes deeper when it reaches its maximum depth the sample cartridge closure
mechanism shuts trapping all the material inside it the sample cartridge is then withdrawn from the outer harpoon
sheath and pulled back into the spacecraft the sample is then brought back to a terrestrial laboratory where scientists
examine the collected samples in a pristine environment
before we journey here we need to work here in the lab studying comet and asteroid analogs
in order to determine how much energy is required to penetrate different depths in various density material
we've designed and built a harpoon test laboratory although the actual mission will use a cannon for safety reasons
we've employed a ballista to fire the harpoons by correlating the imparted energy
versus the penetration depth we will know how to size the explosive charge for the actual mission
the harpoon lab allows us to study how the tip geometry cross section and the mass of the harpoon affect its
penetration this has allowed us to optimize the harpoon sheath for a range of possible
comet densities although sample return missions can be quite costly and complex they offer
important advantages over missions that study their subjects from a distance sample return missions allow terrestrial
laboratories to study in far greater detail with a variety of techniques and can even be studied by future
generations with technologies that have not been invented yet
[Music]
so
[Music]
[Music]
[Music] well hello everybody this is scott
roberts from explore scientific and the explore alliance and this is our 94th global star party
our theme tonight is collisions and creation and we have an amazing lineup
of speakers that are going to be showing you all manner of uh of this theme and
we've got quite a few astrophotographers on tonight as well so i think that no
matter what you're interested in astronomy is you're going to want to watch this program
at the beginning of our program i usually do a introduction of david levy but
some people that are joining me tonight include several people here and i'm going to let them all say something
before we get started so let's let's bring on john briggs
first okay john is uh he is joining us remotely from the uh
durfee the historic durfee high school uh observatory and um where he's uh he's
he's been recruited to do some work so there you go
and you are muted john so i have to unmute
there how about now yeah well um we're introducing david it was
my pleasure to begin to get to know david at the stellophane convention uh decades
ago a david would come down from canada and uh and was a was a prominent figure
at stallophane even back in those days when we were all so much younger and uh
it was occurring to me that i'm here in fall river massachusetts it's actually the city i
was born in but it would have been um almost exactly
40 years ago um that i had the privilege of hosting
david when he visited this part of the world to meet people at the center the harvard
smithsonian center for astrophysics because he anticipated that he was going
to be discovering comets and he wanted to really understand
thoroughly how to go about reporting them when the time came
and so it was a a great and memorable visit and he actually stayed a few nights in the
apartment that i shared uh in cambridge with a couple of other astronomers
and uh but as par i believe it was part of that visit i had the further privilege of showing david my
observatory under construction uh in the in the town next door to fall
river massachusetts and um it's just uh these events that we share together these star parties uh as
time goes by bringing old friends together it's um um it's it's very
thought uh provoking thinking about all the times uh gone by and all the
experience we've shared but anyway it's uh great to see david and if i can scott
i will just take 15 seconds or something to share let's see this screen
if that works share yeah and uh it is this is actually an
observatory that i've spoken about before this is a wide-angle lens
and um i've i've shared some pictures of this on of the series it's an eight inch
alvin clark uh mounted by warner and swayze and it
was uh built uh circa 1886. fall river was a typical new england uh
textile mill town and interestingly alvin clark himself lived here in fall
river in the 1830s and his son alvin bran clark
was born here in fall river and alvin graham clark was present when
this telescope was dedicated at the original derpy high school anyway lots
of interesting history i love that stuff and i hope you see the picture but with those uh words to share
i will uh uh disengage and let somebody else say hello okay all right so next up
we'll bring um we'll bring adrian bradley up uh adrian uh
i think owes a lot of his inspiration in astronomy um
to um to david levy so let's
bring you in okay here we go actually should probably switch to
speaker phone yes you're driving all right
so don't don't don't look at the screen well no i will uh
so i'm gonna give my recollections of uh david levy
to uh to start i actually could show
some of the images if needed but i will i'll just
yeah this for this we need to keep it short because we have a long list of speakers but
yeah but it would be really cool to know more about your interactions how you first
met david well the
university low browse and a talk that you gave dave david
at the university of michigan you uh you gave a talk about observing you told us
if you don't write it down it's not an occupation and i felt uh
guilty as charged because i tended to look and i never tended to write anything down
but it was a uh it was a world famous picture of the uh southern cross
that got me interested in doing nightscapes and night photography it inspired me to go out and capture the
stars because i realized it was possible from uh from seeing that simple
plain image that uh that uh you shared during your talk when you're at michigan
i happened to take a photo and um at the time we didn't know each other
well as time went on and as we met up when you gave remote talks for low brows
and then you gave them you gave remote talks for the warren astronomical society
we became friends i shared my images and i am still
very much honored to have had you praise those images is beautiful
and that you really like them i was hoping that you know the images
would make people would move people to love the night sky your
you know with your comments and your your love of space it's one of the many
reasons that i continue to go out and look up at the stars and um and even
look at the move when the moon is out so uh thank you for helping me on my path my good friend
david and hopefully we shall meet again soon thank you very much thank you very much
great okay so um and uh all i think all of us that are uh here on global star
party would have something to say but i'm gonna end this uh this uh
round of introductions uh about david i think this would be a nice theme to do
maybe at every global star party but i'm going to bring on mike wiesner mike is working
hand in hand with me to develop the arizona dark sky star party and it is of
course the full title of it the david h levy arizona dark sky star party so i'll
bring i'll bring michael on now and uh here we go
hello thank you scott yeah so um yeah i i knew david's name
uh as a long time subscriber to sky and telescope magazine starting back in
1962 i still have all those issues from since all the way back to then um
but i would you know read his columns and and i got really excited about what he always had to tell me and of course knew
him from common levy shoemaker uh nine that plowed into jupiter um so you know
here was this famous guy that i had only knew his name well in 2005 i got a chance to meet
david and i'm going to share my screen just very briefly here if i do this correctly because i usually
screw it up okay so let's see if this works
oh geez this new version wants me to allow it oh boy
hang on here just a minute
zoom keeps forgetting that i keep allowing this to happen all right
oh i gotta go oh bummer ah man i'll take your time to do this so we'll do it
later okay so not securing my screen but um i i first met david in person in 2005
he was a guest speaker at oceanside photo and telescope back when they would do the southern
california astronomy expos and so that was quite a big thrill to me
to actually get to meet david um you know this famous astronomer person who's done all kinds of comet
discoveries and asteroid discoveries and discovering this big rock set of rocks
that plowed into jupiter and he gave a talk on you know how he discovered comments well then the next time that i
got to meet david was at the first what was supposed to be annual david h levy
arizona dark sky star parties held at karchner cavern state park here
in arizona back in 2019 and i wish i'd gotten to share my screen
because i have a really nice photo of david and i there together
but when that star party happened back in 2019 i began
sort of twisting scott's arm to say hey let's have one up here in oracle arizona
oracle arizona is the first arizona state park system to be
designated as an ida international dark sky park karcher caverns was the second
so having the david h levy arizona dark sky star party here in oracle state park which is
about four miles over my shoulder from where i live uh would just be so exciting to me
personally to have david come up here and and experience our night sky that i
experienced every clear night when i'm out so um i'm excited that scott finally agreed
to have one up here in oracle he actually visited oracle and oracle state park for a couple of days and
nights back in february and he was excited and i'm looking forward to having david
coming up here and getting him excited about our night sky here in oracle
when you come to oracle state park for the star party in september uh you're
going to be amazed at what you're going to see we have very dark skies here
i see the zodiacal light from my observatory here on the west side of town
i've seen the triangulum galaxy m33 with my naked eye i have seen gagenshine from
here where i live in oracle so we can have very nice dark skies and i'm looking
forward to it again and i think you're going to see an incredible lineup of speakers and it's going to be an awesome event so
come on out so david what do you think
thank you so much is it my turn now scotty i guess it's your turn now
was that a nice enough introduction i didn't say my piece okay david levy is like one of my
very best friends and uh you know i uh he has added so many dimensions to
uh you know my understanding of astronomy and and how to inspire
other people to get involved in astronomy but uh i think the most profound thing has just
been his friendship and uh really
if if all the astronomy could go away and just the friendship would still be left i wouldn't be very happy with that
so thank you david well thank you and i really am surprised
by this outpouring of welcomes from some of you this afternoon uh this this is a very special
93rd global star party it is about impacts
and it turns out i will begin by saying that impacts are among the most common things
in the long history of our solar system in fact if you were to ask the earth
how many times it has been clobbered by comets and asteroids
the earth would probably say it's almost kind of boring it happened so often
on the scale of the solar system but on the scale of humanity
on the scale of 2022 back into say 1994.
it is very rare and we discovered
the shoemakers and i discovered um sl9
in march of 1993 we were we were going
to um doing a regular search it was a cloudy night there's quite a story to that
but the whole story really began as i remember scanning
i remember guiding the telescope it was taking this field and i said i sure hope i don't have to
show this picture to anybody because jupiter is swamping out the eye eyepiece
i did find a faint star to guide on for both of the pictures
and the next day carolyn looks up from her stereo microscope and she says i don't
know what i have but it looks like a squashed comet
and that began a story the comet wrapped itself around the three of us and took us
on a tour through its final year in orbit around jupiter
it collided uh on the 16th of july 1994
and we did not know until about 20 or 30 minutes after the
collision they were planning a press conference and they were going to give the first press conference to the shoemakers and
me to describe the discovery of the comets just in case we didn't see anything when
we're preparing for the press conference they taught us how to sit in the chair so that our jackets don't get frimbled
they taught us what to do if scott roberts calls and starts asking questions they taught us what to do
they taught us what to do with gary cohn palmer calls from england and starts asking all kinds of questions and even
if adrian bradley comes up with a good picture which we knew i didn't know at the time
that he would but anyway we're doing all this
when um one of the people from the space telescope
institute rushes into the auditorium and bounds down the stairs and silently shows
gene the pictures of the first impact and gina stops what he says
and he looks up and he bursts out you mean they saw plumes
why did that end the rehearsal we just had this wonderful
wonderful rush to uh to uh on computers to check the email
and by then excuse me by then they had
all kinds of things going on and we had impacts and sightseeing
excuse me this is not covert this is me so this is these are allergies this is allergies yeah i think i'm
allergic to comments today oh and the comment the comma turned out to put on a beautiful performance
comets don't always do that in fact it was while i was on nbc the day before the impacts
they asked me to come up with a a comment about whether comets could be
predicted or not and without even thinking i had gotten about one hour sleep the night before
and i just said comets are like cats they both have tails and they both do
precisely what they want and this comet sure as heck did precisely what they want
but today we're going to be talking about impacts in the larger sense two people that i know very very well
bill hartman and don davis from the planetary science institute who came up with the idea
during the apollo years that the origin of the moon
could be traced to a major impact of a mars-sized planetesimal
that hit the earth and sent huge amounts of material into space
into earth orbit and eventually these pieces call us to form what we now see
and there's a reason for talking about the moon right now today this hour
because the moon is going to put on a show on sunday night there is going to be a total eclipse of
the moon those of us who live in england might miss it or you might get it just the beginning as as as
uh as it goes down i mean just the ending
but in montreal canada uh it'll start at the middle of the
evening and where i live in arizona it starts at moonrise
and i think first contact of the umbrella shadow begins a few minutes after numerals
we're really looking forward to that and me and you know i've read all the stuff on the internet and nobody seemed to have
have stated what the real possibility is for this
eclipse because we can predict when it's going to happen we can predict the maximum of
it one thing we cannot predict is how light or dark the shadow will be
the darkest lunar eclipse i ever saw was the morning of december the 30th 1963.
it was right after of a few months after the eruption the explosive eruption of a major
volcano a gun and sent material into the stratosphere
and it darkened the earth's shadow so that at mid totality i couldn't find
the moon that's how dark it was the scale is called the denson scale
if it is at l equals five then it's a very bright lunar eclipse
kind of a pale whitish pink and it's almost not noticeable
and then l2 is darker i mean you know l4 is darker o3 is quite
dark l2 is very dark l1 is quite dark but the one i saw in 1963 was an l0
where the moon almost disappeared friend of mine constantine papa cosmis
still living in canada now he reported from a dark sky
seeing the a totally eclipsed moon about as bright as a fifth magnitude star
so we don't know what we're going to get this time what we do know is that a few
months ago let's see
a few months ago mount hunga tonga hunger for ip
a gigantic undersea volcano about 60 miles north of tangapati
uh and it spewed lots of dust in the upper stratosphere a second eruption took place in april of the ma of the
mountain anak krakatoa child of krakatoa krakatoa is the one that
did that famous eruption in 1983. so we've had two eruptions
i anticipate that the shadow will be pretty dark and that the eclipse were going to be on sunday you don't want to miss it will
probably be quite dark and i think i don't really want to make a prediction we get we'll have a few days and then
we'll know just go out and take a look and now we get to the poem
and this is a traditional pawn for a lunar eclipse was written by thomas
hardy in 1903 after witnessing an eclipse a year earlier from london
by shadow earth from pole to central sea now steels along the moon's make shine
an even monochrome and curving line of imperturbable serenity
how shall i link such sun cast symmetry with the torn trouble form i know is
thine that profile placid is a brown divine with continents of moil and misery
and can immense mortality but throw so small as shade and heaven's high human scheme be hemmed
within the coast's yanart implies is such the stellar gauge of earthly
shell nation at war with nation brains the team heroes
and women fairer than the skies thank you and thank you scotty wow that was very very
nice thank you david thank you wonderful wonderful okay so um
uh up next is uh our segment for door prizes our door prizes are
coordinated with the astronomical league uh each week the executive officers of
the astronomical league come up with a series of questions um that uh answered correctly puts you in
the running for our valuable door prizes that we have um we have um
uh uh this week we have john goss john has been with the league for
[Music] many years i i think i've seen john at astronomical league events
uh almost the entire time i've been attending them myself and so um uh you know i think that uh
i think that's great uh here's john now and uh i do want to say i do want to say
that uh you know and and i i said every global star party uh you know the
astronomical league is really one of the amazing
you know membership organizations that you can belong to as an astronomer you know and
i'm talking globally at this point the astronomically has
i think it's over 80 observing programs they are involved in
recognition awards that date back you know they have 75 years of
service to the amateur astronomy community and you know within that community have
been of course beginners like like many of us are beginners but also people who are
really uh quite serious about the research that they do they've made major contributions
discoveries many of them famous in their own right and so you'll be in good company when you join
the astronomical league um to join all you have to do is go to
astroleague.org and you'll be one of uh over 20 000 members of the of
the league so john i'm going to turn it over to you man all right well thank you scott
um i'd like to start out um by emphasizing something that uh you all
have been saying in a certain way with the uh uh arizona dark sky david levy
arizona dark sky party and others uh such as alcon which we have coming up on
why why why do all this you know why why go to these star parties why go to alpine
alcon because you know amateur astronomy sometimes has the reputation of being a rather solitary avocation
and it is sometimes but not not all the time you know we have a lot of members who spend a lot of their um vacation
time of their vacation money each year to go to various events such
as alcon or such as some of these other star parties so why do they do it what are they where they get out of it
well i think that they recognize that amateur astronomy is a little bit more
than just what you see in the eyepiece to really appreciate that there is a big
range of understanding that you have to go through and these star parties star gatherings conventions allow you to do
that you get to meet uh fairly famous amateur astronomers or
professional astronomers or authors or magazine editors or vendors
or imagers or sketchers you know the whole list you get to meet all these people and expand your knowledge of the
hobby and you yourself can contribute likewise by telling other people what you're interested in what got what got
you in the hobby what what what you really like um so you know there's just a whole range
of reasons to go to star parties and i'll cover this a little bit more at the end here but i want to get on
these questions because before i start talking too much one moment please
okay we we have three questions tonight uh but before we do that i'm gonna go into answering last week's three
questions just so it's not a big mystery to everybody so let's uh start on that we we like to
give people a friendly reminder when looking through their scopes at the sun
make sure you have the proper filters make sure you know what you're doing and if you don't have someone teach you how
to do it it's when you have the right filters and know what you're doing it's really completely completely safe
oops sorry let's get back there
question number one from last week carol orange president of the astronomically presented these three
questions so it's it's up to me to spill the beans on them um question number one
was as you can read the james webb space telescopes mid mid infrared instrument are finally
reaches super cold temperatures what temperatures are those in kelvin fahrenheit and celsius well these are
it's really cold uh seven degrees k which is about one excuse me 144
degrees uh minus 447 degrees fahrenheit and minus 266 degrees celsius
uh pretty darn cool question number two who is jessica watkins i'm sorry to say
i i didn't know this with myself i i had to go go look this up myself dr walken watkins is currently serving
as a mission specialist on nasa's spacex crew fourth mission to the international space station so she's she's been up in
space uh she's a veteran of it now question number three
how many moons does the planet mars have i think we've all been taught through the years it has two moons i think it
still does has a lot of artificial satellites now but two natural satellites
so the winners of these three questions um uh will their names will be drawn uh at
a later star party and if they're the lucky ones they will receive some gifts from the astronomical league
enough said of that let's go on to the three questions for this week
we were just talking about this lunar eclipse coming up on on sunday night
okay we have a total lunar eclipse on sunday night during totality stars near the moon can be seen because as you know
during a full moon stars next to the moon are just completely blotted out uh what double star shines just 10
degrees to the upper moons to the moon's upper right people with keen eye sight can resolve it is it a
spica b zupinel janubi c
antares one of those three uh next question
number two la superba which can be viewed through binoculars on a spring evening is a
prime example of what type of star now this is a great star for beginners to look at for one thing a all you really
need are binoculars if you have keen eyesight you might be able to see it but binoculars will bring it into view and
it's not hard to find if you have the proper star map it's up up near the big
dipper the handle of the big dipper it's uh pretty easy to find but anyway answers are
uh is la suburba a red giant is it a variable
or is it a carbon star now just as a hint there could be more than one choice on this question
number three drum roll please i've asked this question a lot because
it changes it helps us all keep perspective of where we are in space and where are
where the other planets are all around us the closest planet to earth tonight is a mercury
b venus c mars so if you have the
knowledge of these three answers please send them to a secretary at astroleague.org
um with your answers and your name if if you're correct your name will be put into the list for the final final
winners uh for the door prize before i i leave this i'd like to
mention that this friday night we have astronomical league live on um
coming up on may 13th yeah we're featuring dr jessica noviello
who i will give a really interesting i know she will give a really interesting talk because i've heard this before on
cryovolcanism that is what has really shaped the evolution the
characteristics of the moons in the outer solar system pretty interesting stuff and it's amazing that that
we can have this type of information these days with all this the spacecraft reconnaissance spacecraft and
uh discoveries i think that's that is really cool so be sure to tune in on this friday night
one more thing before i get out of here alcon 2022 uh i wanted to bring this up
uh talk about these star parties again on why why they come to something like alcon
well this year alcon has a number of interesting subjects to talk about we have
talks on really a wide range from beginners to advanced to experts to
different this off-beat stuff we have talks on what variable star observing
talks on various missions that nasa is up to these days be interesting we have uh we even have
an astronaut harrison schmidt who you all might have heard of he happened to be the on the final
apollo mission uh we have tours of course go to new mexico you got to go to the
vla and some other tours to the local observatories in the albuquerque area
we have a keynote speaker who is pretty darn good uh
stack of the seti institute great um really looking forward to seeing him uh
he's always always pretty pretty popular but anyway uh these are just some of the reasons to come to alecon and other
astronomy gatherings have their own particular reasons as well so as we go into spring and in the summer
and into fall this is the time of year to start doing this stuff getting out and meeting new people and seeing old friends again at gatherings
like this so with that i'm going to stop and
try to turn this back over okay you did it perfectly there we go
and thank you scott for giving me the opportunity to uh shoot my mouth off again thank you
we love it so we love it uh we're very happy to have the astronomical league on with us each week
um they contribute so much to our you know our community
i can't really say enough about it okay but
thanks again john and do you already know who's going to be on
the next uh uh global star party
no you don't okay am i supposed to no [Laughter]
sometimes it's a mystery to me okay all right well they they the the
the officers kind of cycle through so we'll we'll see who's on next time uh one of the people that is going to be on
next global star party will be uh goddard's uh caitlin aarons and she's going to be talking about the
uh the new decatal planetary science decadal survey
um uh you know presentations that were given and stuff so she's going to sum that up for us
well it's it's funny funny that you bring up caitlyn because she'll probably talk your ear off about the green bank star quest star party i'm sure she will
yeah yeah sure she will yeah she was on with us uh for quite a number of months on actually seven exact months because
she gave seven months of science on our programs which was really awesome she brought in some brought on some really
amazing scientists uh that talked about all kinds of things
including some of my my favorite subjects are astrobiology you know so
but anyhow we're going to keep moving on here our next speaker is none other than adrian
bradley and adrian uh often shares with us his nightscapes i don't know if he's
uh did you make it back into a safe uh yes i'm back to the command center
he um depends on the background you see you you see a
you see a galactic center on the ground i see it yes that's the that's the home base
and um yeah if i'm in the car there's a different image um and actually i'll go ahead and i'll
go ahead and take it scott and yeah go ahead go through um we i'm showing the angle
of this uh milky way galactic center and then the um
the northern the northern bulge which um we in the northern hemisphere
see all the time and you see it in a lot of um images um when you when you're looking
at pictures of the milky way and one thing i wanted to bring out and tie into
um david and to all the all of us who love the hobby
there are so many different ways that you can approach the hobby if you were to look up milky way imaging
and you would likely see if it comes from the northern hemisphere
more often than not the milky way is going to be at the angle just like in the back of my image
and um near the end i'm going to try and tie this to collisions as well because it
involves just looking at the night sky so i'm going to go ahead and share my
screen and let's see it'll be this screen so i'm gonna drop some of
these other pictures couple things i wanted to do um and i'll try and do it quickly a bit
of a surprise for you show a process by which i uh
process one of these images and a lot of that when i went out to shoot
northern part of the lower peninsula of michigan a lot of the images that i shot
um appear to have lots of satellites in them as i was um
as i was shooting so let's see how well this works um
most of the time after it comes out of my camera i'll change the tint and i've figured
out that this is around the real color of the sky maybe
lower the temperature a bit just missed and the sky tends to be this grayish
this blue this grayish blue color when you're looking up at the sky at
night the image you're seeing on the screen is exactly what you would see if this
site were border one with the exception you may not see the color in the north
american nebula here you may not see all of this detail
the way that that detail comes out is to then do some things
like uh darken the sky do highlights if i lift shadows now you can kind of see this was a road
with a bridge um and then from this point
it's all editing and i don't think i'll share the i usually
send it to photoshop to um bring out the milky way further
but we're gonna leave this as a we're gonna leave this as an image that
you would see if you were standing there in the middle of this the road on this bridge with me
this is what you would be looking at and your eyes would adjust a little bit
and in the sky and then you see the bridge a little better you see the sky
now what we do as far as noise reduction we've got some options
to get rid of some of the grain that you saw and that is the beginning
of an image that um this is a as you see it image as
you're looking up at the sky if you're there with me this is what you see
it's not spectacular but then again it is because cassiopeia is right here these are the
stars of cassiopeia you can hardly see that these are the stars of the double cluster
and light from the heart and soul is showing up over here um
there was another image that i took
this is a little more processed and this is where one more satellites
but then two you're seeing more detail processing brings out the
detail and when i shoot with a wide-angle lens the trees lean in a bit because of
the way that the lens is made the options the other option to this is to try a panorama
but if you're gonna do a panorama you should probably [Music]
you should probably shoot the ground as well because it's nice to see
this turned out pretty well you can see how bright this region of the milky way is and then over with
cassiopeia it dims it uh it disappears and
most of the time when you're shooting you will see meteors um that's how i tend to
i tend to think of those in terms of tonight's theme you're witnessing collisions in action if you witness a
meteor brighten up it collides with the earth's atmosphere most of
all the time that i've been out none of them have gotten so bright and then they've they
haven't fallen to earth where i'm standing so so far i haven't had to
you know collide with one of the meteors myself that that wouldn't be too good
um but um seeing the meteors collide and then
having a picture of it sometimes the meteor pictures are a little harder
to distinguish from the uh the actual streaks of light and see
here's a here you've got a bright streak and these are some of the
we'll call them finished images where i tried to make them detailed and yet pretty
and this particular image was my goal for the night you're seeing the satellite travel here and you're
seeing the coat hanger as well i always like to make see whenever i shoot this part of the milky way
i like to see that i've gotten light from some of the some important parts of it
that um the nebula like m17 here in m16 the sagittarius cloud m5 and even a
little bit of light from the triffid m20 which is hiding in here there's
countless other objects here open cluster here the stinger
and you can see the stars from sagittarius here i like to make sure that the some of
that detail appears when i process i don't want to smooth over
all of these things or get rid of all of these stars and all you have is a bright ribbon
and the foreground's beautiful there are there's a time and place for that but
when you and when you are there to enjoy and capture the night sky
it my goal is always to find a way to combine the two efforts
make it a beautiful photo so you have the river below but also make it a photo that
an astronomer would love and this is so i took this shot this is what i
wanted to take um this was the full shot right here
that's the full image and i was able to crop it in and so you have the river the reason i
wanted that shot here and i did it in portrait mode this is the same shot
six months ago orion and friends are a part of
that same view ice is covering everything including that boat launch over here
and it gives you an appreciation for how the sky changes and we call it milky
way season when the core is in the night sky
but to me milky way season is year round especially if you go to places where
it's easier to see the full milky way or any part see any parts of the milky
way including the fainter regions around cassiopeia and orion
so some other images that i was able to take i'll just i'll go through them
um this is an old image and the the theme here is
milky way rising and i just kept shooting this is astronomical
astronomical twilight before dawn so astronomical dawn and you've got this
color that appears shooting with the same camera in a
collision in process above it meteor coming down
then the shots that i was able to take this past weekend um
with a giant light behind me i'm still able to get the milky way i won't turn down an image if i think that there's
something pretty about it or a value or you know something of value there's so much light it's casting a shadow of the
bridge that i was standing on and i thought this was me over here
standing but i'm not so sure but it casts the shadow of the trust of the bridge on the trees which it
otherwise i think this would have been a beautiful photo so here i'm
standing at the boat launch and experimenting with different ways to try and
frame the milky way here the cat's eyes the stinger the scorpion resting on
the tree this is another i cropped to this angle at one point um
to see how that would look one of the problems that i'm looking to resolve when i do noise reduction
this turns into mush and i'd like to work at using some of the uh
tips and tricks that bob fugate who's come who's gonna be on global star party later tonight has talked about signal to
noise and um you know and i'm working on not only
signal to noise these this is a single image um with the tracker i have i am able to do
composites so i can work with
taking a picture for the sky and then taking a picture where the
you know the ground would be more solid and so that's one thing
that i think will add to some of the detail that that i'll be working on purely for my own just to see where i
can go with it i 30 seconds with the um
camera that i have and i'm able to get images of the milky way like this
and then there's the panorama there's the this is the composite image
one minute on the sky gives it plenty of time for a satellite to photobomb it one minute on the um
before the foreground which is the river and it's a little smoother it cleaned up a
little more when i did that you know a little less and there's a little bit this detail here
there's some real detail the the grass that's here so i love i love
seeing the reflection of the milky way yeah look at that yeah it's cool right in the river that's
this was this was uh one of two shots that i absolutely loved when i
finally got a chance to work through it this was the other one um this one i guess no one there's a collision
here and there's satellites this may be a meteor as well just look at the trail
that's definitely a geosynchronous satellite this is a 30-second shot
i remember seeing the shape of the milky way
i didn't see any color or and i didn't see um
what i would see at a portal 2 or border one site but i did see this region
and i'm thinking i want to go ahead and frame the shot here because this will probably be the best 30 second
shot that i'll take and turns out it was this was to me the cleanest of the
milky way shots any time and one of the things i was going to point out um this region over here is an h.a
region in ophiuchus that a lot of imagers are focused real hard they'll take a lot of frames to bring
that region out um it is there is well there's a lot of h.a
and a lot of other information coming from the bulge of the uh of
of this part of the galaxy and so some of that is real it looks
kind of modeled in a mess but you're looking at our galactic center and it's not just this
crazy horse looking shape it's not just this
it's this entire region is um a part of the galactic center and of
course you can see sagittarius which points approximately to where the black hole is that's guarded by dust and
all of these things you can't see it naked eye but you know that in this particular region where my air where the
cursor is is the center of the galaxy and that's something
that's not lost and the road is a metaphor for me because
i'm on this road chasing this um anytime i go out and i'm looking to do
milky way photography in particular you can do night sky photography of all types
um milky way is my favorite but there there are a lot of other ways
you can capture the beauty of the night sky and so
and you can capture it in different phases this is during nautical twilight and that's actually the moon rising
and the milky way fading away and this is that image that you see behind me or at least one of the
versions of the image at four in the morning all of these shots i believe were taken at four in
the morning because i couldn't wait till summer to um when it would rise like this
around 9 00 p.m or you know rise like this around sunset
catching it at four in the morning where you get you get really as dark as sky as you can get
in the region that you're in um there were a couple of other and you can
see my differences and how i've tried to process these images
in their see of the one lone winter milky way shot so
that's what i wanted to present today scott and um thank you adrian and
i and again it's the love of the night sky is what drives me to try and present it in a number of
different ways sometimes it's not perfect but in other times
i learn something from whatever it is that i've shot and i go okay well this is something i want to
try to you know improve something in the image and it reveals uh the experience that we have within
ourselves as we're doing this stuff so that is so cool thank you very much absolutely adrian
okay so up next here is gary palmer gary is in uh the uk and um
uh he's been on global star party many times i've met him i got the opportunity to meet him in person at a
solar event that daystar was conducting and really found him to be
not only very very knowledgeable but um you know a very warm and friendly guy
and so if you get a chance to meet him at a star party or any kind of
event um where gary's attending you're gonna you're gonna find what i found so
uh gary i'm gonna turn it over to you man thank you thanks scott thanks for the introduction um
hi to everybody out there and everybody that's joined us tonight on the uh the panel
um i was a little bit of a loss to sort of what to run through tonight and um i saw
your sort of title come up with collisions and then i thought well we've got the eclipse coming up
uh lunar eclipse at the weekend so why not run through a bit of lunar processing
and maybe a way to enhance it which is something you might call it a little bit artistic in a sense yeah because it's
not really uh um run-of-the-mill sort of thing that you would do with an eclipse
but i generally find to pick the styles out in the background dslr cameras work
well um but the problem is is you're taking singular shots and depending on what's going on and the
conditions the shot can look quite bland and look a little bit washed out if you
switch over to a cmos camera um there's a mix there they don't generally
grab the same sort of color as the dslr does so for me i've always done it with a dslr so if i
share this screen up at the moment uh make sure i've got the right one hopefully you can see that
yeah so that was the last lunar eclipse we had a few years back
now and it was cloudy yeah it's very cloudy here so really did struggle with this
but one a few years before that it was a lot clearer so
i enhanced it and the way that i enhanced it was about 15 minutes before
it started its eclipse path was to actually do a small mosaic
and you can do that with the dslr um but what you'll find is because the moon's not eclipsed then it's going
to show you a lot more detail so what we've done is actually overlaid
it with the mosaic that carries the high detail and then the coloring behind it
is the natural coloring it's just brought out a little bit more so the way of getting around doing that
is to take these separate shots so if we bring these up in um bring them up in registex
first because you'll process these if you can get a couple of them together
um the more you get together if you're going to do a mozart the better it is so if this was with a dslr and try at
least to get sort of 20 shots of this one particular area and then we would move up
the moon um so this would create a four panel mosaic to give you some example
one of the key things when people are doing a lot of these sort of shots is they really over sharpen the image right
at this point and it's a good idea not to over sharpen it and what i mean by that is it's
really easy to tell if you're over sharpening you'll get a white line and come down this edge here and that happens in most lunar shots so if we
increase the wavelet's layer here and we start to sharpen up let me just put the highlight
box over it you'll see the line there starting to go white once that's there it's really hard to
get um to remove it from the image and it's also going to cause lots of
problems so doing the mosaics fairly straightforward now you could if you've got a
um mono uh cmos camera do your mozart with that
yeah once it's together you can just resize it in photoshop to match the dslr image
but once you've got these together the other thing is is increase the brightness if i reset this
yeah this is the standard image as it sort of comes in it's quite dark
and for most of these lunar shots like this i'm more interested in the the terminator line here so we really need
to brighten it up and using uh the histogram in registex is the real easy way of doing it when it is somewhere
around about 130 yeah and be a little bit funny sometimes
somewhere around there and that gives you a good brightness and it also makes it really easy to join these images
together okay so once you've got all of that you save them all off yeah and then you will
move over to bringing them into photoshop so we bring them in on photoshop we've got all of the images
here first thing you need to do is crop any stack lines off of the outside they're
really not going to help you um on putting these together we're going to do
these manually as well so um if they're only three four five even up
to a dozen images i generally doing manually you'll get a lot better alignment on it but if we set up the
crop box just crop each one
take any uh stack lines off the edge if you find it's a little bit blurry in some area then just clip that
off if you can as long as you're not losing any of the actual image itself go to the next one do exactly the same
thing
and then this is the first image now i've already cropped this what i generally do now is duplicate it
the background's locked and it's very hard to work with um so your background actually making a duplication just right click on the
duplicate layer make the second layer once you've got that delete the background one we don't need it anymore
so we're going to delete that then we need to increase the canvas size and that's to take the other images in
so if we go up to image and then go down to canva size and switch it over to percent if you
want look at your orientation of your image we're going to be moving down and we also
might be moving off at a slight angle depends on how precise you were the angle of the moon in the sky so the way
your telescoping camera is you might find that you're moving slightly off on the shots
to get it all in so we're going to go to percent on this and
then we're just going to type in 200 and see how we go in each direction
let's see if i can type it correctly there we go 200 again and then we're going to click
on the top in the center and that's going to make the canvas out i'm not overly worried that this is
going to be really big at the moment i just want to make sure that we're all going to fit in
okay so go to the image before you've already propped it already got it highlighted
i'm going to copy that back to the main image
and then we're going to paste it if in select the move tool
and move it around roughly line it up where it is it's gonna be somewhere in there
and then just zoom in
back to the move tool and then align these up keep an eye on this edge here this is
the main thing when we do one of the processes in a minute it will automatically merge all of these
together and make these nice and sensible if you double click the hand it'll bring it back to the full size image
and zoom in a little bit more for the next layer to go to the next image along that one
copy it back to the main image and then post it back in
and exactly the same thing get the move tool work out where it's going to be
yeah so move the image up a little bit one thing i always suggest on doing any
mosaics doesn't matter whether it's solar luna anything at all you really want to make sure that you've
got a good overlap on it these programs don't like it if you haven't got a good overlap
so sometimes it's easier just to use your mouse key your arrow keys on your keyboard
and then the final panel is going to come in down here okay so last one
copy that back to the main image and then paste it
in
okay again keep an eye on your edge line if you're not sure on it just zoom in a little bit just so you can see it
go back to your move tool yeah and just to line it up make sure it's nice
if you look at the craters there you can see they're all lining up you don't need a lot of panels when
you're doing this a lot of people think that you need loads and loads and loads of images you don't even with a
high-speed camera you only need a 50 hundred maximum 200. if you do too many you're
going to get too much distortion in it when you're doing these mosaics so now we can go back to the hand tool
double tap on it and then what we're going to do it's going to highlight around the outside
just so we can crop off the canvas we're going to leave in the edges photoshop's got some
quite wizard tools in it these days so if we go to crop and leave it like that
bring it back up to its size now what we're going to do it's going to go into select and select all layers
and then we're going to go to the edit panel and go all the way down to auto blend layers
leave it as standard on panorama and you want to make sure that seamless tones and colors are checked
certainly if you're using a color camera and the content aware now what this will do
is is this will match this background that's missing um it's quite a good add-on in photoshop
over the last few years it was always a pain to get the right tone
of black on the background of any image so if we just click ok on that
that will go away and do what it's doing
that's it so we can deselect everything there so if we go up to the select menu
just deselect there we go now we're going to go to the main box
here and we're just going to flatten the image so if you right click on it yeah just go flatten image
that's your complete image now that's all together i can't see any drawing lines if you zoom into it
it's all nice and neat so back to the hand
what we need to do is just really brighten it up and sharpen it a little bit anytime you use wavelets or any other
sharpening tool before photoshop is going to leave a residual noise on there with some cameras and it certainly will
if you get you going or your iso too high so if we go to
the noise just go into the speckle and then you've got one or two choices
um go back into your filters you can either use a smart sharpen yeah
or your unsharp mask smart sharpen works quite well on this that's way too harsh at the moment so
i'm going to drop that back just about
bringing it up a little bit you can if you've got a little bit of residual noise there run in with a noise
reduction using this we haven't got a lot of noise there so we can drop that back
okay and then the last thing is is just really to get it a little bit brighter
so we can use the curves tool for that bring the curves in um somewhere around anywhere between
five and ten put a holding marker in down on your black point
and then a holding marker in at the top normally on the top one on it up somewhere around 250.
there we go just try and get the line back straight if it jumps off like what it did then when i did it
okay now we can play around they're going to hold the black and white points so we can hold around we can get a
little bit more contrast in and then we can brighten up a little bit
something like that that's it there's your mosaic together
you can then if you've got the color matching image resize this you can just copy the whole image and overlay over the top when you
overlay it if i just duplicate this just to show you
when you overlay it here the one that you're going to go over the top make sure it's black and white and
then put it on as a luminosity layer and you can blend it in on your amount then
you're on your opacity as to how much you want to come through
there you go
well i appreciate that uh thorough explanation gary it's uh
you've made it um to me you've actually made it a fairly simple
process just using photoshop and now it's something that i can uh try because
i'm just known for taking my camera one shot at the moon and go
and um what would you have to think on that agent is that our atmosphere is moving
so if you imagine it's twisting all the time so with the dslr it's quite slow
and essentially every time it downloads to the card yeah even though you might have it set up you know
a hundred of a second or one sixtieth of a second or something like that yeah it's repeat process so even when it's
multiple shooting it get up to seven eight frames before it starts locking up on the card and
then it's gonna free itself up but in a sense it's quite slow and the problem with that is is if you actually
look at 10 or 15 shots of the moon yeah or any other planet right uh object
you'll find that only one or two of those is clear
just rubbish you're just throwing them away and that's what i'm saying if you can
an hour before it starts going into eclipse you can play around you've got a good bit of time then to take a few
different sections a few different shots um if you've got a um
even a deep sky camera you know something like this um that shot there was actually done on
one of the other cameras but at the same time i used the 294 yeah um it is perfectly capable switch
it into 8-bit planetary mode and it it will still punch out you know 20-30 frames a
second which is a lot faster than your dslr so right but the dslr picks up the nice
red color and that's really what depicts an eclipse and when you look at them um
through a cmos camera doesn't matter how much you enhance you can never really draw that deepness
out that's nice yeah i what i would have to try if given the
opportunity and i might just shoot at the moon and try it i do have a spotting scope with a t-ring on it
and it's i think it's like a focal like an f ratio of eight um so that's something i can at least
try and practice the mosaic method with that because i take my camera put it on
connect it to the spotting scope and track and then i can start taking frames that way lock
it in and start start shooting it that way if you get quite a lot of frames the
dslr images and the the downside of this is is we've got um
very large images coming in for each single frame now you know they're like 40 off of these cameras and more you
know with some of them and the problem with that is a lot of the software that we use is actually quite old
yeah so um unless you've got something like pixel insight pixel insight will see the
images it will decode coloring and you're in there and you can sharpen it or denoise it or do whatever you want
but if you're using something like registex register is going to throw a spanner in the works when you put images
in that big so what you might want to use is use something like uh pip
pipp and thank you so if you've got them over and you can then move them into a
different format yeah and that will then help you with your science uh and and what i mean by
size is file size rather than actual image size um so pip works quite well it's free
um and when we get some really really poor seeing uh that's the one you turn to to stabilize anything up
um yeah so you can take them over a good few sessions but you know got a good few days yet uh moon's out and like what i
was doing there i was just getting ready and just having a practice with a few bits of equipment
um and that's what came out of it you know so that was actually off of a 925
edge so it's quite a big scope and you're still fitting in you know within four panels but you're getting that high
resolution there yeah so what you could do there is is bolt your
dslr onto something like that get the nice deep colors when it's in eclipse and you're going to fit the moon in that
field of view as well yep i'm going to i'll take those notes
unfortunately months ago i agreed to be somewhere in vegas in a bowling center
uh full disclosure and there's an eclipse going on and we're supposed to be bowling i'm going to be living
vicariously through you i still plan on practicing the technique so that at least i have that down
um would you say one quick question would you say that that technique would work on a solar eclipse as well
yeah it does um it's it's a little bit more awkward because
color cameras don't like image in the sun it doesn't matter what what filter you
put on there if you're being dead honest a color camera your back's against the wall one that's
straight away because um depending on what filter you're using let's just say we're using the hydro now
for filter you're only using one pixel the red pixel so three quarters of your
sensitivity you've just thrown the white hold out um i have done some nice uh eclipse
stuff and while we're on the subject of that i know you've got the big eclipse out there in uh
2024. yeah i was actually going a little bit further ahead for the uk and the
uk's got a 97 one in 2026.
um if you want a hundred percent jump on a boat and get in the atlantic um or reykjavik or spain
yeah is where you're gonna get 100 part but it does run right up past ireland
up so i was looking at that the other day and just working out a few things bailey's beads i think you get bailey's
beads at least before it breaks off and yeah it's gonna be tight that it's still
quite early on it anyway you know something like that needs a year or two more to home in a little bit on it um and also
where you're gonna go but yeah it really depends on the moon with with what you're gonna do um i've um
with solo i've done them with dslrs just because you can set the dslr up to
capture one every 30 seconds that's what i would play 45 seconds and then you can just turn it
into a movie and it's really easy you know just say in photoshop for an evening to color it all
up and do everything and it's done but um yeah it's good fun it's good playing
around all of it um and it's also good from battling the weather
yeah yeah in general you you know when something comes along like this some areas will get cloud they will
get rained out you know um and that first eclipse that i showed um
you know that was a little bit less detailed that was taken through the cloud that was held you know through the cloud
the gaps that were coming over and it's just being patient you know it doesn't go it's not like a
solar eclipse where it's over in like two or three minutes you've got a good hour hour and a half
on this yeah before it completely um before it breaks the totality's gone so
yeah unless you're unlucky to get a storm run through or something there's a good chance you're getting
something yeah i'm unlucky this time because that the precise moment the totality
i do believe that's when our session starts six games so unless i want to be late for that and
i've considered that um i i will be i'll be following along so
those of you out there in uh astronomy land please take a photo an interesting uh photo
opportunity um especially further east i believe the uh core of the milky way will be at that
angle that i was shooting at and the lunar eclipse will be above it to the right
yeah so it's um it's actually going to be a really i i was going to go right
back to that same spot until i looked at the calendar and said all right so i got to throw i have to throw an orb down a
lane so that that was my challenge to um the landscape uh astrophotography the last
few events here i've had to travel you know i've had to move yeah
you know last mercury transit if i stayed there i want to go you know
um and i think the one before that there was quite a lot of high cloud here so i just went up north in the uk and it was
clear up there yeah that dude you know sometimes that's what it takes yeah
all right scott i've taken who's taking gary's timeline
thank you so much no no problem it's always good it's always fun to join everybody on it thanks everyone
okay well up next is dr daniel barth uh daniel uh was
he runs a series called how do you know it's usually broadcast every monday at about
4 p.m central and our last presentation was about
the building blocks of life that are contained in asteroids and i thought wow
you know we didn't discuss this with each other that you know we were having a show on
collisions and creation uh ahead of time and so i said you got to come on global star party maybe talk
about it a little bit uh daniel do you want to come on
you are muted here we go there we go thanks scott uh just a quick apology to
everybody i this is my office studio and i have a lovely west facing picture window
i am not usually appearing on camera looking like a waxing crest moon but that's just the lighting right now
i tried to adjust my lighting in studio and i can't i can't compensate for the sun anyway we did a uh we did a lovely how
do you know show and it's interesting when we talk about impactors uh we're usually talking about
we think of the dinosaur killer we think of this brilliant streak of light in the night sky
a lot of impactors are very tiny very subtle and many people think impactors oh that's
when a meteorite or excuse me a meteoroid or an asteroid strikes a planetary atmosphere or
strikes the surface of a lunar body but that's not all there is when we talk about impacts they really shape the
entire universe as we know it the first idea that impacts really
shaped everything comes from uh piercing le plus a french scientist and
astronomer in the 1770s and he came up and he said oh we we have
what we call what he called a nebular theory he said stars form from clouds of gas that collapse
and if we think about it these are all these microscopic particles colliding together and forming a sun
these ideas from laplace's nebular theory have progressed over the last
couple of centuries and we we saw that ooh we have these dusty rings around stars
and we're seeing ah planets form in these dusty rings and we came up with
the accretion theory and we said oh little collisions form planets
big planetesimals crash together and make full-fledged planets and the crashing continues until basically most
of the material is used up or herded if you will by planetary massive
bodies into stable orbits and the heavy bombardment period ends
well this idea of self-assembly uh we go uh recently people were talking about ah
dark matter in the early universe could have condensed directly into black holes black holes seed galaxies
stars form uh self-assembly automatically out of clouds of
dust and gas and we get galaxies self-assembled planet self-assemble
and so we get to this part where everybody kind of goes we're all good astro
astrophysicists so far and then we get to the squishy part with astrobiology and people kind of
they cringe a little bit but the question has always been is life a self-assembly process as well
and again we're we're talking about bleeding edge scientific theories and hypotheses here friends so
don't don't email me and say you can't prove that i know very well we cannot but we have these working theories and
hypotheses and we use them as a context as a frame to interpret the data that we get
and one of the interesting things we talk about with biogenesis
where do these molecules come from people for a long time said oh you
couldn't uh you couldn't possibly have an uh
non-creationist uh self-assembly of life how would that happen the molecules are so big they're so complex they couldn't
just happen and then we start to look at the insides of meteorites and we scratch our heads
and we go gee liz we're finding a lot of nucleotide bases to take you back to
your high school biology class rna dna these twisted double helix molecules
and the ribose sugars make the size of the ladder and it's these nucleotide bases that make the rungs
and watson crick and linus pauling was in their pitching too
uh find the molecule that codes for all life dna of course and there's only
four basic letters five if you count rna but there's only four basic letters and
there's comes in only pairs and it sees sequences you have the entire alphabet the codes for all the proteins all the
biological structures and you go okay well that's fine how did this stuff assemble from a
non-living world to a living world collisions impacts yes
and now we're seeing these biomolecules and we have currently as of 2022 people
have announced we found all five nucleotide bases in meteorites
okay let's just go ahead and i'm going to
dispose of this idea that well meteorites land on the earth and immediately life invades them and
contaminates them right to their cores ah these are these are stony rocks
friends and most of them have fusion crusts when they land on earth i think
terrestrial contamination doesn't penetrate into the very core of meteorites and we won't even get into
the allen hills with the are they or are they not microfossils but we find when we crack open these
meteorites and we look at the interiors when we do the chemical analyses we find all these nucleotide bases are there
not only do we find all the nucleotide bases are there but we're also finding many of the amino acids are found in
meteorite fragments and so we look at this and we say wow do
factors deliver these biomolecules that seed life
the building blocks that allows life to form when you have a lovely
surface with all the necessary minerals a solid surface you have water
you have an atmosphere that isn't too corrosive or unfriendly the temperatures are biologically reasonable and are we
getting these impactors raining down and seeding our planet well you back that question up a bit you
say okay but wait a minute if we're finding these nucleotide bases inside the meteorites
and a lot of people are in the background right now are screaming osiris-rex
dan osiris yes we've we've sent osiris-rex up and we've sampled asteroid bennu and we're hoping to silence the
people who say oh life invades by getting a pristine sample uh scott and i
were talking about this on the how do you know program i said you know if you find all these molecules inside the
sample in benue there's going to be doubting thomases who say ah osiris-rex
wasn't perfectly clean uh and to some extent you kind of say well how much evidence will it take to convince you
science is like a steamroller the doubting thomases get rolled over eventually the data cascades and becomes
a wave a tsunami and it rolls over the objections and then we go back and we look at it but if we think about these biomolecules
forming inside or being found inside meteorite fragments we have two
kind of competing ideas one that oh somehow when the meteorite the meteoroid
excuse me assembles when the asteroid assembles there's sufficient chemistry going on inside that stony
object to assemble these biomolecules the other hypothesis which i find far
more compelling is that in fact dust grains in a cloud surrounding a new
protostar a new newly ignited star these dust grains form what we refer to as
catalytic surfaces we know that in a sense catalysts form surfaces
where it becomes convenient for atoms to interact and assemble into more complex
molecules these dust grains very famously help stars form because they have a lot of surface area and they
radiate away the heat that allows the core to compact and ignition nuclear ignition to occur
well if these dust grains have that much surface area they can by themselves form catalytic surfaces we know all the
necessary oxygen carbon hydrogen uh nitrogen molecules are there
in dusty clouds surrounding newly formed stars we know they're there because we find them on the planets
well indeed are the dust particles forming catalytic surfaces are these biomolecules these nucleotide bases
these amino acids are they self-assembling using these dust grains as catalytic
surfaces and then the dust grains accrete tiny collisions collide and stick collide and stick
eventually building up pebble size you know meter
decimeter kilometer-sized objects and ah now all the biomolecules are
trapped inside and if we think about these objects
these asteroids these meteoroids these planetesimals swirling around the sun all in their independent orbits
well a lot of them end up falling down gravity wells we say oh they collide
with planets but if we think of it in a space-time sense the space around a star is pock-marked
with these gravity wells and the wells aren't stable you can't say ooh i'll put something out over here where there's no
gravity uh or microgravity it won't fall into a well into a planet because the
planets are all orbiting the gravity wells aren't stable they move around and we know that these planets change their
orbits over cosmic time so we get these collisions
and then the question comes is life a self-assembling process
and this has tremendous implications for our understanding of data
if life is indeed a self-assembling process as stars are self-assembling planets are
self-assembling nebulae are self-assembling galaxies or self-assembling if life is just another
piece of this self-assembly theory if autobiogenesis is in fact the way the universe works
then life not to say intelligent life but basic life should be quite common
we recently had in a nasa blog the many worlds blog
a very senior scientist came out and he said we need nasa's role and we need to
continue this role nasa needs to tamp down these unrealistic interpretations that we may
have found signs of lift in current or past data nasa needs to resist this
interpretation i'm like whoa this is not science friends this is pope
urban the a speaking from the grave it's possessing you oh my gosh we must we
must tamp down and shut down particular interpretations that's not science
we see the data different people see the data and at the bleeding edge of science there's a lot of conflict there's a lot
of disagreement but the truth does emerge truth is a lowercase t scientists spell truth with
capital t and we talk about these ideas of simplest life forms and we say gee
is this life indeed self-assembling wherever conditions are right
current indications the oldest fossils the newest claim for oldest fossil comes
from a group of canadian scientists and samples from northern canada and
they're looking at things and they're saying you know what these date back to within
1 to 300 million years after the continents first formed
so you're thinking of a young planet heats up in the interior because of trapped energy from radioactivity the
interior begins to melt if the planet differentiates iron and nickel heavy
metals sink to the core the lightweight floaty bits that's the kinetic rock that
forms our continental masses and the mantle is a dense rock that's
molten and underneath and you go well gee if life was on earth
within a couple of hundred million years of the continents becoming solid and stable
so they're no longer being rolled underneath by a very turbulent interior like macaroni boiling in a pot
of water but they form a stable raft where you've got a stable surface where you have biologically
friendly surfaces top poweredge that allows water to
collect in basins and the primitive birth atmosphere would have been a reducing atmosphere and miller and urane
in the 1950s they did that famous experiment they took they believed to be the atmosphere
of the early earth hydrogen methane carbon dioxide nitrogen water vapor they
put it in a jar they hit it with an electric spark and they wow they found all sorts of things all
kinds of amino acids and the nucleotide bases were self-assembling in this little micro
environment and we saved samples of this stuff right it's been reanalyzed uh recently and
they say oh there's a lot more stuff in there that miller and yuri were able to find because we have better instrumentality now
this idea that we're saving samples to reinvestigate as we become more clever
and have better instruments we just this year cracked open a 50 year old sample from apollo 17
and it's been in deep freeze for a half a century and why did we wait uh because
as we become more clever as we learn more we're able to ask better questions and
when we ask better questions we're able to take our new technology and develop better instrumentation to see if we can
answer these questions these sorts of questions are going to be coming and a lot of people are saying i
can't wait next year the sample from osiris-rex taken from the asteroid bennu
comes back to earth but you know it's going to take decades for that data to
come out lots of people around the world right now are writing proposals i want a chunk
i want a piece give me a gram give me half a gram give me a microgram i can do what i want with this this little bit
but the scientists are going to say ah we're not going to parcel it all out they're going to take a fair amount of
this and they're going to squirrel it away in the deep freeze and they're going to say you know what we're going to save
this for our children's children who will be cleverer
we hope and certainly better informed than we are we have
this sound principle that scientific knowledge will advance
and this idea that tiny collisions can influence very great things
and if life is indeed self-assembling then we've got some surprises coming
when we put boots on the ground on mars when we start exploring the interior of moons like
enchiladas and we go and we look into the subsurface oceans i i have this
recurring dream that there's this robotic probe that cranks up the nuclear
thermal generator melts its way down into the free water and then something
swims by the lens i just have this recurring dream that this will happen uh it's an exciting time friends it's an
exciting time yes and uh i look forward to lots of this stuff but there's uh there's a
whole program on this how do you know on the explore uh scientific website and
scott has shown us for that you can download and uh frankly
i love living in the future and i can't wait for none what comes next so
there we go i hope you all enjoyed that tonight thanks very much now each week uh daniel puts together a
um a study guide as well and uh we have a whole page devoted to that so i'll
i'll uh post that link here in a moment um and also you have a
digital free digital download book astronomy for educators astronomy for educators and my newest book star mentor
which is part of the patrick moore practical astronomy series from springer is due out this month
it's available for pre-order on amazon and on the springer website and uh
i'm hoping that people will see it in their hands star mentor was really my answer to the
pandemic so many people who either found themselves isolated without someone to
help them learn about astronomy and at the same time people in clubs we
have a huge influx of new binocular owners and new telescope owners who are coming up to people in clubs and tugging
on their sleeve and saying oh hey can you teach me a lot of us know a great deal but we're less
comfortable when someone says teach me and star mentor is designed to be your guide too
to help you learn how to effectively teach and share what you know and love about astronomy right yeah very interesting daniel
because our clubs in particular um we isolated ourselves as well so it's
taken it's taken some clubs um some time to get back to
giving to the public there's still some concern the central arkansas astronomy society that i work with occasionally
they just had one of their first public star parties in two years about a month ago uh sugar creek another group i work with
is just starting to come back and people are saying is the pandemic over where can i go
because we've always said oh you're a new telescope owner go find your local club there's tons of
people friends you haven't met yet people to help you but a lot of people still find themselves isolated and
people who come to me and said well you've taught astronomy for years how do i do this how do i help people uh and that's that's what i did is i
took uh something like four decades book about teaching and it's like squish it into a
book we have my own little uh nebular compaction theory going on there take all this stuff i've done for years
and squish it into uh weed it out and squish it into a book and i hope it'll be a big success give
me the name of the book again i definitely like the the book is star mentor okay
and it's from it's being published by springer and
if you look up star mentor and comma daniel barth in any search engine you'll
find it uh it is on amazon for pre-order amazon estimates that it will be out
sometime in late june but my friends at springer say late may is
more likely we've we've gone through we've corrected all the proofs and everything and sent
it back to them and so their production team is working on it now so i'm hoping in the next couple of weeks we'll we'll
start seeing copies which will be really exciting all right sounds good thank you yes sir
excellent presentation okay well thank you very much um
up next is uh professor kareem jaffer john abbott college and the royal
astronomical society of canada montreal center he has he's joining us and
i'll uh he's created a video which i'll run but i'll let karine introduce it
here we go thanks scott um so i actually wanted to uh first off to say hi it's nice to nice to make it uh today was a
bit of a tight schedule but i was glad to be able to jump on and i jumped on in time to see gary's wonderful uh
tutorial on how to create that that fantastic moon image with the mosaic
approach i gotta i'm gonna have to try this and uh daniel dr barth i'm just always amazed
my jaw always drops i feel like i'm back in university you know sitting there and i wish i had popcorn with me to enjoy
really it's better than a marvel movie at times um today's topic is collisions and creation
and that creation part just i had to take a few minutes to talk about because as you're all aware uh with the rasc
we've been doing a lot of stuff lately and one of the things we've been doing is the shooting for the moon webinars
and events to help celebrate the artemis mission which will hopefully launch at some point
august fingers crossed but we'll talk more about that in a few minutes the other thing that we're doing is
we've launched a second version of our creation station so those of you who remember from last year we had our
creation station which was for youth ages five to twelve inviting them to just express their
creativity about space so we set up a space on our website we asked kids to give stories poems drawings
even even actual comic books if they wanted to and just share their love and their
imagination about space this year we're increasing the age range all the way up to age 17 and the
submission style so that you can have multimedia you can create a song you can create a short tic talk video if you
want to but we also have a special themed area on the moon because what we've been doing at the
rasc is we've been talking to everyone about this excitement about going back to the moon
so this past saturday for international astronomy day we finally had a in-person
event we had astrofest here in montreal and astrofest was at the rio tinto alcan
planetarium it was 12 straight hours of astronomy fun it was activities it was
talks it was workshops and at the end of that evening while we were
still having the observing in montreal we had this webinar across the nation at
the rasc so i put together a short video summary of our day's activities and i'm going to
ask scott to share it now and then afterwards i'll pick up from there and add in one more bit to tell you what's
coming up next so scott if you can share the video for me all right here we go
thank you yeah here we are
surface 2022 at the rio tinto akan planetarium we are really excited for the program
today we've got lots and lots of activities 20 partners giving us a ton
of astronomy outreach including we've got workshops on mirrors we've got workshops on satellites we've got
workshops on rockets we've got workshops on the actual astrophysics and astronomy solar observing and then we've got
observing of moon and stars and deep sky objects tonight including a lot of eaa
electronically assisted astronomy we've got lots of people coming throughout the day we hope you'll enjoy
we're going to give you a snapshot of the entire day over the next little bit thanks for joining us this is the aria-c
montreal center throughout the day i took the time to interview people about their excitement
about going back to the moon so you'll see snippets of that
and gaby science yourself no g's about it are you why are you excited about going back to the moon personally i'm
really excited that the first woman and person of color are gonna be going back to the room yeah i'm really happy because it's been already 50 years since
the first since a person has been on the moon it's about time this looks like such a fun exciting
activity can't wait to see it
irex coordinator and our rask ga presenter can you tell us why are you
excited about the artemis missions i'm really excited about the artist's mission because the moon is something
that we interact with on a daily basis but we're going to have that sentiment like they have during the apollo
missions where we're going to get to look up again and say there are people there and i hear so many stories from
people of that generation saying they have that feeling but that's been gone for generations but we're going to get to experience that in just a few years
well that's fantastic and just like our rash creation station irex has kids using their imagination to picture solar
systems from all across the galaxy and so this is fantastic to see
tell us about your love of the moon so something about the moon
why are you excited about humanity going back to the moon so we gotta clean up the mess we left the last time think of all the stuff
they left there a couple of lander modules that rover golf clubs come on pick up your pieces
what do you love about sharing observing with people during the day with the sun and during the evening with the moon
i think that people are surprised that you can actually look at the sun and then they are also interested in the
sunspots and just sharing my love with the people
what about sketching the moon why do you do that um [Music]
time but normal has his wonderful telescope set up on the moon up there
you can just see it up there the nice quarter moon that's risen nicely because we are in the late afternoon and of
course the quarter moon rises right around midday
nebraska ambassador and astrolabe extraordinaire tell us about your moon excitement and interest
so the moon for me is my introduction to astronomy um i i was born just after the
moon landings the last room landing and i'm looking for the day that we will go
back but meanwhile all i can do is look at it so that's what i've been doing for
as long as i can remember
from the csa why are you excited about the artemis missions i'm excited about it because it'll mean
that a canadian astronaut gets to circumnavigate the moon for the first time
it's sky and looking at the moon well it's the most amazing thing that nature can give us
you can see that the the night the united skies can give you
a lot of thoughts you can be calm you can look at the wonderful things in the
sky even just a comment or whatever it appears is it's
so beautiful you can see all the pictures for uh for the astrophotographers
you can see all the galaxies nebulas everything that offers
our system you can see that we are just tiny tiny tiny in a big universe
we have a beautiful bright moon above the olympic stadium you can see out here we have a wonderful
crowd not only lined up to take a look at the first quarter moon but also enjoying the q a that's being live
broadcast on the screen and we have lots and lots of people waiting for this star and moon party
that's going to happen in a little bit we saw that there's music that's going to come in between
beautiful live view of the moon here through the around fulham's optics and a nice little telescope made
i'll zoom out in a moment so you can see it take a look through
beautiful beautiful design
[Music] [Laughter]
[Music]
uh
[Music]
and so we're looking forward to enjoying that for the rest of the night thank you for montreal
so we had a blast there on saturday we had almost 30 different uh presenters
animators speakers including astronaut davidson jacques in the canadian space agency
we had live music in the evening in between the keynote presentation and the actual outdoor observing night and then
the after observing we had 12 different telescope setups a couple of them had
multiple telescopes available we had eaa being broadcast onto a very large 200-foot screen
including an ev scope that was live broadcasting to it later in the evening when people got kind of tired of the
moon and they wanted something a little bit more and then part of what we did is we kind of just advertised the other events that
we have coming up through the summer and the other things that all of our societies do and the one that i want to draw your
attention to before i end is this coming sunday night in eastern daylight time we
have this wonderful lunar eclipse that we've already been talking about tonight we're not able to do it live in person
as a public event because it's a sunday night very late and we're just in quebec
stopping the mask mandate on saturday so we don't have the policy set up yet to
do our own private events so what we're doing instead is we're hoping to have all of our members get
together and then we're hoping to share our images through the virtual telescope project in
italy uh gianluca has been amazing setting this up in the past couple of years
and so please do if you're if you're unable to see it because you have bad weather or if you just want to see
images from across the world everyone who can see the the total lunar eclipse join us at
virtualtelescope.eu and we'll be there all night uh it's going to be it's going to be a blast
scott back to you great wonderful so um
it's always wonderful to have young kareem thank you so much for presenting that i think that you guys do
outreach in the best possible way you make it so festive and so interesting uh
i can imagine you are uh you know turning on many many people to
looking up at the sky so that's really awesome i hope so one of the fantastic things this past saturday was
that a third of our no actually half of our volunteers were youth members they were either students or youth members
all the way down to age 12 and all the way up to age 25 recent graduates from
university that have just they came back and said we want to do more outreach what can we do wonderful wonderful
that's music to my ears awesome okay uh so up next will be
jason gonzale the vast reaches uh jason is well known for his amazing
astrophotography and uh he comes on a global star party from time to time he has a very busy
schedule but we're glad that he was able to squeeze us in so jason it's all yours
i think scott i don't know if my schedule is more busy than anyone else but
sometimes it is a challenge trying to schedule it up so uh thanks for having me and thank you i don't specify the
time i just barely made it in the nick of time but um yeah i always enjoy coming on i think
it's generally around once a month i make it make it on here but um
so i'm i'm really just gonna show some of the images images i worked on over the last month i've got some some new
stuff um some older stuff that i'm kind of recycling in creative ways so
i'll walk through all that stuff i'm going to share now from a different computer
like i normally do let me know
if this comes through
maybe don't know my work or familiar with it i do i kind of dip my toes in you know
all the aspects of master photography i can you know i've been uh big into solar
imaging for a while um got some lunar to share which i don't
shoot very often but i did in this past month and i've got a lot of deep sky work that i
concentrate on um when i get into like nightscape and milky way stuff too although i don't really have that
today to show but um what you're looking at here is a um you know one of the more detailed looks
at the solo chromosphere that i was able to get this was shot with the six inch acromat the explore
scientific ar152 and uh the daystar quark chromosphere um
that combo gives a really long focal length uh because the the daystar quark has a barlow included in
it so it shoots at over 4000 millimeters of focal length so
just to get a field of view like this this is actually a four panel mosaic
i missed i guess gary's talk earlier about uh lunar mosaics
at least that's the indication i got as to what he was talking about but um yeah this is kind of put together
similarly where i i shoot separate panels and then compile them together
into one master image and uh this shows an active region that came across the sun
in late april um you know over the course of a couple weeks you can watch these active regions
drift from one limb as in as the sun rotates it comes around and will disappear on the
far side or the um this is the western limb but um
this was a you know we're getting back into a time of more solar activity and this
was a really nice active region that came up and had a lot of flaring action and
obviously a lot of sunspots a lot of times you know with solar
processing we'll try to accentuate the details of the chromosphere by inverting the image
but this is a more natural look inverting the image when it has sunspots always confuses people a little bit
because the sunspots end up being bright but they're this is kind of a natural
tone where the sun spots are dark and that the chromosphere actually
blocks the light from the photosphere below so you kind of get this hazy uh fuzzy look to the chromosphere
and you know what you're looking at is basically hydrogen plasma floating over the photosphere that's a little bit opaque
so it kind of obscures that blinding light from underneath
got this image last month also and like i said i don't get into
much lunar photography but that was cool look at that yeah um
kind of had a little bit of fun with this one you know when the moon is at least in a given
phase like this it's pretty near impossible to shoot the dark side of the earth sign so this is a
composite of two images one taken in an earlier phase to get the earth shine
uh clearly and then basically laid
underneath the the um the gibbous phase so you get the you know the full disc of the moon and
what the reason i like to do this is because it gives a lot of depth and 3d
appearance to the moon especially when you you know over take some over exposed
exposures to get the the glow and the addition of the star layer below it
really gives a nice kind of 3d pop to the whole scene so
kind of a fun way to process uh lunar imagery one i don't do very often but i
got a pretty good response in this one so i'm tempted to get back into it but this is a shot with the eight inch hd
telescope so you know a lot of pretty nice detail down into the
craters
yeah gary palmer showed us a version of his quarter moon with very similar
really deep detail like you're showing us here um
and uh i want to say is the star field the exact star field it would be behind
but i won't i won't uh no unless it really is it does give it a nice effect of
being in spain you know being in space which is uh which i think works
yeah it's a little bit art and science i guess uh mixed there but you know i i tend to try to have some
creative fun with my yeah my pictures and you know there's
something to make it a little bit different put my own spin on it but looking at the these details you
know i was kind of picking some of these out like this is uh rupus recta the straight wall which is a
fault line on the moon just a few uh maybe like one or two kilometers wide
so when you can resolve that you know you're doing something right anyway and um
you know there's a couple other features i look to when i try to see you know how much detail i've captured
uh quite a bit you know like the crater looks up here
so it's a fun one this image ended up being 400 megapixels the total size once
i had the whole canvas set so
definitely a lot of information in that picture it's beautiful and then um yeah so
i was able to finally uh get to some dark skies after a long hiatus
i went up there um just a couple
a couple weeks ago and i shot um with the tpo ultrawide
telescope which is a wide field telescope and one advantage of shooting in dark skies is you really get to see
some deep exposures and this was shot with just just under four hours of exposure
time [Music] and those familiar with this field will notice that it's the m81 and m82
galaxy pair down here but what shows up in the in the image are these uh big dust lanes
extending up over to the left here is the it's called the volcano nebula
and then there's another one over here to the right these are actually um ifn which is integrated flux nebula
and this is um dust basically serous clouds of dust
around the halo of the milky way galaxy and they're illuminated by the combined starlight of all the
you know stars within the galaxy so that we're looking at the basically the
you know the dust lanes that the outside observer would see um when you're looking at our galaxy but
we're peering out through them but these are some of the faintest structures that
you can go after and shoot and so i was really happy to see these come through with this telescope system and i've shot
color data here also turn that on
um i haven't processed this out yet but this is kind of what it looks like with the star layer removed and again it's
kind of messy because i haven't gone through and cleaned it up yet but uh you will really see
those structures in the in the clouds there with the stars turned back on
all right so real nice photo at one point i remember and i think it was in our
astronomy group they mentioned a lot of folks thought it was noise and kept trying to get rid of that
medium because they thought it was some sort of noise in their photos when they were shooting at m51 you know m81
and m82 and i guess it was either discovered later or
we realized that that belonged in the image yeah
it can be hard especially shooting from a light polluted location um to kind of
separate that uh structure from the background and you know
without enough exposure with a lot of light pollution it can look pretty messy
um you know i look at this image i have on the screen now and i see you know even though i was shooting from dark
skies i don't think four hours of integration was even enough to to clean it all up i mean i can i can you know
work on it with noise reduction etc but there's definitely
especially when you look at look at it without the stars
definitely could use more explosion like that especially in the deep
background but i was pretty happy with you know there's a lot of
i mean they do look like cirrus clouds you know there's a lot of fine structure in there incredible but it's really
really hard to to pull that structure out i mean you can look at where the image started this is kind of like the
raw stretch and then this is that how did that
boost the contrast of those structures yeah and you that's definitely good data
there and it's um if if it's gonna be a start and you're
gonna keep working on it it's definitely a great start once you're seeing the actual data there
i think it's uh i think it's a good looking photo on its own even if you don't continue
you know trying to or getting more data to add to it and or cleaning this this was a one-night uh
image and i'm gonna try to keep it like that okay like i said you know i got got out to those dark skies i totally collected
this data all in one night so i kind of want to finish the image like this but i'm about halfway through actually
yeah i'm blown away i mean i think it's yeah it still looks great yeah um
i kind of like the one night warrior kind of thing like you know i could sit here and i could add
you know 50 hours on for my backyard i'd do it if i wanted but um
i don't even know it would probably be a detriment to the image overall if i yeah because my skies are you know
portal six i like pollution so it would take a lot of integration to get what i got in just a few hours there
that's the benefit of dark sky jeff y says i think it is dark matter
damage very difficult all right so um i just want to kind of
wrap up today with to show a few videos i've been working a lot
on these short form videos um for either instagram or facebook reels and uh
tic tac and those those platforms that
take these you know vertical crop short format videos but i've been trying to polish them up and i think
it's a it's a good way to reach a larger audience you i'll show here my instagram
reels feed and we can click through some of these but you know that one of the things with these videos is i
always um you know add the the commercially available music that
you know you can tag to these to these videos that scott you don't know of any issues playing that on this stream right
uh i just as long as we don't have like uh you know copyrighted music or
something like that well that's i mean it is copyright i can just play them without the music i mean yeah let's do
that okay otherwise they just shut down the whole stream so yeah because it's um it is copyrighted
music i mean they it's it's available for you to choose on these um but i will
say that you're going to look at some of these and the image is going to be dancing around and it's dancing around the music that's not there so just okay
bear with me maybe you could hum it along the way i'll sing it
um but actually i can play these out of my uh if anybody wants to see them
you can go to my instagram profile oh this is my username up here the vast
reaches um my website links to my social profiles and then also
um you know i use the same username on all the other social platforms so if you
want to find it you can get get to it there what i'm going to do is i'm going to pull these videos out of a folder
that don't have sound so okay we can just look at them that way okay
i don't want to like break up the streamer or whatever happens yeah that's always a drag when that happens
all right so i'll just i'll narrate these how about that so um it works i've got a few of these here let's see
which ones will be interesting okay so this is one um
i'm a backyard astrophotographer here are some of my pictures that have been featured by nasa so i just kind of
went through and and uh did a short video on the the nasa apon awards that i
i received so that was the soul nebula this one is the jellyfish
with the planet mars up at the top of the screen that was all captured in one shot
one session then this one is the arc 273
galaxy pair interacting galaxy pair and that's a long focal length image
with the edge hd but one i'm rather proud of that's super
let's see this is uh this is another look at the soul nebula
so kind of zoom in on this image and one thing that i always liked about this image is that you know as i worked on it
it kind of felt like it started to stare back at me i really got the impression of this face
here right kind of scary
yeah it's like it looks like a demon or something yeah
so i pulled the stars out there and you know it helps accentuate it a little bit more um
this one here is uh my shot of m 100
and this is a 28 hour exposure of that galaxy pair
fy says he doesn't want you to go to internet jail so right
wow you've seen that look yeah you see what i'm doing here i've kind of animated the
some depth into these videos it's something i've
if you watch like the the painting and the zooming uh you can see that i've added depth information to
the star field so it gives you the impression of flying through space that's cool
i hear like star trek theme music playing in my head
you're gonna watch it all to get the real soundtrack um
this one is the uh this is the cat sign nebula you know it's interesting too
by looking at this thing moving and tilting it seems like you're you're collecting
some information visually that you might not get if you were just staring at it
without it moving around yeah i totally agree with that you know what i mean i think you know like on
this one for example you know i've i've got foreground i've got background stars yeah nebula's floating in the middle
and then the the background galaxies are all on a layer far far away so you do get that
like it's more of an obvious participation in viewing it you know yeah to get uh it's almost like viewing
it like a like a like a macro uh photograph you know like you get this
idea like it's almost like a miniature model of the galaxy it's awesome
pretty cool you really enjoy that that's great
uh this is the james webb space telescope i think i shared this on a previous global star party but not the
animated version so as the jwst was flying out to its parking orbit
i was able to catch this sequence of images with the jwst moving
wow and it was moving past the rosette nebula so i zoomed out and got this nice view of the rosette beautiful
zoom in a little bit and then it'll zoom back to the to the telescope but
i i like this format because i think it communicates something in the images that you don't get with a still image
you know i posted the jwst is just like a streak in the image and said this is
jwst but this kind of brings it to life that's what i'm doing yeah
there it is it also gives you well it gives you an idea of just how huge the structures are
you know those are much further away than the jwst but they're that huge
when you look at it from our vantage point that that sense of scale was something that i couldn't communicate
with the still image and i think this does it jeff wise says it makes these objects
seem more like a place or position instead of flat
yeah here's my um unidentified objects near
the moon uh posted on may the fourth be with you [Laughter]
you can imagine the imperial march behind this this image
it looks like they came out of hyperspace for that one yeah yeah that was idea and this is zooming around that moon
image i just shared with the group earlier
again you know the the focus pull effect you know you get a lot of depth of perception in the moon shot
beautiful yeah it's a beautiful shot it's really one of the more beautiful
full you know full disc images i've seen of the moon
this is uh the flaming star in tadpoles area nice that you know i did the st still
image and then i you know just kind of animated it
one doesn't have as much of the star depth effect but it's still there a little bit
that was a pretty nice looking image though here's a
look at saturn go on the raw video feed
then the in color then the final processed image
everybody likes a good saturn especially when you
you catch a glimpse of the uh i don't know if that was a northern or southern pole
but it looked like he had the hexagon there yeah previous years it was a little bit
easier to capture when now it's the rings are starting to flatten them out and uh it's becoming less visible
here is the uh this is a planetary nebula called sharpless 2 71.
it's a pretty complex little planetary nebula very tiny actually and uh
this one's the subject of a lot of scientific study because it's suspected that it's a triple star system
that in one of the stars basically um you know ended its like red
giant phase in in a planetary nebula but uh because of that
triple star interaction there's a really complex developed shape here where it's not
as regular as some planetary nebula you'd see
yeah let's see we'll finish this off with the solar time lapse
this one dances to some music so it seems a little jarring without the
music but there's 45 minutes of activity and that active region actually i showed
a picture of right at the beginning nice that's a good look at the solar
scope setup too yeah look at that
it's alive
that's cool yeah those sunspots remind me that we've
been getting a lot of aurora warnings and
possible activity the one time i did have a chance to go and try and chase it though
there was absolutely nothing going on so i um i just shot at the uh i shot at
the night sky and was happy but um you know excellent
excellent images and i like the uh the creativity you use in putting a lot
of them into these these sort of videos yeah i'm having fun with it you
know yeah i think the music selections also add to it a bit so i
encourage anybody that wants to see i'm just going to hop on over at one of these yeah what i think about that is outreach
i mean that's um it's a perfect way to take the images themselves and
generate even more interest um just because we know we know that no
matter how beautiful your images are when they go out in the wild they're often consumed for about four seconds
and then there's a decision whether they're decent or not and a like button pressed or
yeah or they just move on and with this they'll stop and stay a while and
start to travel through your images more and through it you know
i could see you reaching a lot more people in terms of um you know getting interest especially
your saturn image probably of all these beautiful images your saturn between your saturn image
and the imperial um the imperial uh force coming over the
moon i don't know how many think that that's absolutely real but i'm sure there may be a few that uh went
that went to the grocery store to buy uh some water after in toilet paper after they saw your image
so um very creative way to share the universe with the rest of
us well thanks yeah beautiful fun to do
so yeah like i said you know hop over check it out if you want if you want to see
them um in living color it's you know it's a nice format for a for looking at it on the phone
it's a little awkward for looking at it on the computer i'll give you that but
right okay um it's time for us to take a 10 minute break and
stretch your legs and get a cup of coffee and a sandwich or whatever and um
uh we will be back uh with uh daniel higgins and uh
uh preeta uh peter uh proud i believe is how it's pronounced i i might have
absolutely it's a french name peter thank you
you said peter probably i'm excited to have you on so all
we're going to take 10 minutes and we'll be back with these guys
so here we go
check one two
so
[Music]
well welcome back everybody you are watching the 93rd global star party uh
with our theme of uh collisions and creation and up next is a little change in our
schedule because nico who would who had this time slot uh is having some
internet trouble down there so um daniel higgins
and peter peter how do i pronounce your last name again just think of it okay that's easy l and the x island yeah
okay so um uh i i have learned a a little bit by
looking at your website peter but i'm gonna let daniel introduce you and talk all about what's
going on with astroworld tv so let's bring you guys on here we are terrific
and i'll bow out while you guys take it over right okay dan how are you doing this evening
sir are you are you muted he's muted
he's muted this always happens with uh
it wouldn't it wouldn't be a video if it wouldn't be a video conference if somebody didn't come on muted
it's usually me okay okay so dan not muted what are you doing
there you go now you're not you know he's a show host because uh because he's making
errors it never it never fails
for those of you that watch the show you know that this happens to me all the time i am a
big brain fart in process so that's that's that's what i am so but but
um it's great to be on and we're coming close to a hundred i plan on being here for for global star party 100
i'm so psyched for that but uh um you know yeah i mean uh i've known pete for a couple of years
now yeah uh uh starting through the pandemic before the pandemic yeah right before
we actually met on a video chat i think which was put together by uh jesse wenke who was looking for toxin
astronomy with folks after being isolated for a while and uh you know and and the pandemic
kind of brought about uh masters of pics insight which is uh an offshoot of a couple other websites
that we've been running for a few years ip48b uh image processing for astrophotography
with warren keller and uh and so you know i've been in astro world
i love astroworld that's the first time i've seen this and this is great because i love to have this i have i have
astroworld on when i'm out my observatory you know imaging and uh it's great to kind of you know
we're always so alone sometimes energy uh and then you know we got all these people in the background and it's great
and i wear my you know obligatory guy with the nasa shirt tonight right perfect absolutely [Laughter]
so um what do you i guess uh hopefully i don't know if you've ever heard of if
you've if you've not heard of our website uh masters of picks insight it's not that
um it's something that i do with ron breacher and warren keller both uh picks
inside ambassadors and uh we're not masters the idea of masters of picks
inside is to make you a master and we do that by uh workshops and uh
we've got a facebook group and it's something that started during the
uh because of the pandemic uh warren and i had a website up ip for ap for
a long time and it started out as photoshop instruction then i moved on to
pixen site uh instruction as a subscription site and we decided one day
hey we got all these great subscribers let's try to get together with folks so we started offering three
uh three-day uh workshops where people would go we would go to a site and we'd
do it all across north america canada the u.s and we would give these great three-day workshops and get to meet
people and we start out we give them data we walk them through
it was from basically from a beginner and by the time you left there we went
we started going through intermediate techniques and uh lo and behold in in may of 2020
we had a workshop schedule in san jose and one in buffalo new york it's where my neck of the woods and
the pandemic happened so i'm an i.t i own an i.t company i said you know we could probably do this
online and what we did is we we uh kind of uh we've put together this site
very quickly and uh i think we had over a hundred uh users uh subscribers from around the
world literally around the world uh we have we're on uh seven continents uh uh our subscription
map is is crazy in the past 30 days we've had over uh 3 000 uh sessions
uh and uh it's just it's amazing to see where people are coming we have you know we have people all across
europe uh uh asia you know new zealand uh australia all around the states in
canada down to south america and we've developed quite a nice little group so uh
can i show my website yeah yeah absolutely okay dan you have any questions for me
no i i just want you to come on board and say you know because i i've been always i've been a fan of master's picks
inside since day one i've been taking lessons with ron from pre-masses of
pixel site and um i can't say you know you know you guys have been
great uh so uh just keep on doing what you're doing yeah show the website show people what you got so so what we have
here is we have uh we're basically uh well we're doing we're doing a couple workshops uh workshops a month and we're
trying to build a community here and uh if you subscribe to any of our
workshops uh their lifetime subscriptions and the great thing about it is that uh
we have a private facebook page which is kind of like a support central for pixel sight with uh ron warren uh and then we
we also uh give a quarterly uh free workshop for for everybody so we
pick a topic and or we have a guest and once a quarter or we do that so uh our
next workshop is coming up it's photons to photos number seven uh this is a series where we
uh go and uh we take an object that's in the night sky that people would be imaging and we
go through a two-hour session and we show them how we would process it so you get to look over the shoulder
shoulders of ron and warren while they process the image it's live to ask questions uh you get
all the data at the end and you get the process icons uh and again unlimited uh video playback
uh and then we have our uh image processing for astrophotography this is where it all started this is a series of
short videos on everything fix insight and i'll go through these these two and i also i also i already mentioned our
quick tips uh our members only uh free workshop on a uh on a monthly
basis so again uh it's warren uh warren is the author of the book uh
inside picks insight uh dr ron breacher ron uh it was a student
of bourne's and and he became our uh partner uh when we did the workshops on the road and i'm kind of like the tech
guy in the mc and the host of things and if you have any problems you come talk to me and
we've got a wealth of sponsors out there uh and uh you know they help us keep our costs down but this is kind of a been a
real um passion project for us so on our and we have a bunch of free
stuff and i'm going to go over that so you know this isn't about having to come in and buy a workshop or anything like
that we have a lot of good in free and for information out there too
uh just uh just so the viewers know this if you and correct me if i'm wrong if you purchase a
workshop let's say you purchase uh dialing down the noise um and that's all about getting you know
working with noise reduction and getting the noise out of your image now we know how fast pix insight changes
updates come out or everything comes around if you purchase dialing down the noise
you are able to go to all the dialing that as they go through the cycle again you can go back to it and get the
updated version of it for free because you've already purchased it the first time yeah so the idea here is that we
took our uh we took our we broke down our workshop into uh
uh nine uh two hour workshops uh by the time we added things down to about an hour and a half hour 45 minutes and uh
what it's what what what was just mentioned by dan so in 2020 we did our
first newbies workshop in 2021 we we we did another newbies workshop basically
following uh the same program the same image but now we've updated it with the
newest version of pixensight so it's kind of an evergreen thing and our plan is and we have it on the calendar is to
just repeat the repeat the workshops we are really there for people that picks
insight can be a intimidating program and we're really there to try to get people off the
ground uh and we start out with our newbie workshop and our newbie workshop
here will show you uh how to get a image out of pixel site in as little as
11 steps you know you don't have to use every process uh that they have that they have out there to do this okay uh
so we show you how to just get familiar with the interface and then next step for newbies now we continue on and we
add more processes uh to it and and tell you how to tweak things and then dialing
down the noise tell you how we go through all the noise reduction techniques uh in pixel insight and then
dying up the detail we show you how to bring that detail out and then we go into uh our master and math series which
again all these techniques uh the thing about you know we're really doing art here right and let me say i've never
seen jason's work before holy cow yeah he puts he puts me to
shame uh and i love the videos and so so it props out to jason um but so if you
were to take if you were to take all these courses here you'd have a real complete understanding of what it takes
to get a good image out of pix insight uh and then we have our um
our intermediate series uh you know put it all together okay and this is where we
go and over the tools for image integration so we take it away from that easy uh
batch pre-processing mode and get you into let's see what's going on behind the curtain there uh
mosaics and other special techniques and a huge workshop for us is working with narrowband uh we had uh we have over 150
people turn out for this last workshop that we did there and then uh we have our ask us anything where we have
solicit people have been through the series to come with questions things they don't understand we put together a
a workshop on that and then as i mentioned we have our photons of photo series
and these are all objects we take you through uh some are monochrome lrgb some are one
shot color but we give you the data and we take you through how to process
uh these particular uh images and again once you've uh you know we once you've
signed up for any of our workshops you have uh access i'll go into the narrowband workshop
so this is our recent narrowband workshop and we go through uh it's we split into
three parts and uh this is our 2021. like as dan
mentioned uh we repeat the workshop so we're debating whether or not to take some of the older workshops off because
we hope people would come in and go to uh the newer workshop uh the interesting
thing though too is we we also along with everything we provide uh
chapter markers uh that will show you what the content is
let me see if i put one of those up here
so you would get a narrow brand chapter marker so you know so if there's something in particular you want to go
to we give you timelines and everything here so again uh it is uh it's it's a
it's a labor of love uh by the three of us we also if as i mentioned
these are the workshops we have our ip for ap tutorials
and these are this is a three-part series a foundation series and like the workshop it goes
through step by step starts out with the interface it takes you through and
these are mainly scripted warren has done these and they are uh
you know we think they're they're high quality content here uh but they fit but we go through and these are a little
bite size i i think of them as like a reference and this is what warren based his book or a book around so you come in
here if you want to know specific something about dbe you come and take a look at the dbe workshop here uh the db
tutorial rather and we have our as as part of this we have also what we call our
workflow series and the workflow series is worn again processing different types of objects
and it's always great to look over the shoulder of a bastard when they're doing this and as part of our
uh ip freight pieces we have also what we call that reloaded series and this is set up
uh there's a lot of information on our website but this is set up as kind of a workflow so if you're if you want to do if you
want to see some uh tutorials on noise reduction we'll have the latest uh
picks in sight noise reduction process is here uh we also
whenever pixin site is updated we come here and we will you know uh version
1.8.9 was just introduced well warren and ron are clued in because
they're ambassadors and we can this is the day this is introduced we have a tutorial ready and you can see what's
the latest and greatest uh in here and these are again they're they're anywhere from you know maybe five the longest
maybe a ten minute tutorial but there's over 200 of them but you can search the site but there's enough information here
to kind of show you everything that you've ever want to know uh about uh
pics insight and again we provide course materials and that is uh chronological
uh process icons so you can see a workflow workflow documentation again there there's so much information here
it's almost ridiculous uh and and we're trying to arrange it so that if people come in it's easier
enough for them to go through and then as as i mentioned our quick tips uh section which is where we throw in we
see we see something that is becoming a question we'll throw this in and anybody who subscribed to just one tutorial on our
site can come in here so uh we've recently won done one on star
exterminator uh warren did a uh what we call supplemental on uh uh deconvolution for
for motion blur to round out stars a little bit more uh i've done one on uh creating
uh synthetic flats and also the the hour-long workshops uh
are also here too so again lots of information uh available for
uh all of our users out there and we don't send out emails when there's no information
and if you want to get a taste of what we do we have a free newbies workshop
just go to our workshop page and this is the entire workshop this is the first workshop we ever did there's
no cost to come here you have all the downloads is it that you would have uh during a uh
if you during a normal uh workshop uh we also have on our
uh ipfrappy tutorials a primer and preview page this is a five part series on the
interface pixel site so you understand it and then we give you a sample of all the things we all of our the things we
do on on the website here and again it's free there's no cost to that and finally we have a
another site that's called easy-pixen site and easy pics insight uh goes through
and shows you how to process simple process one shot color dslr
monochromatic lrgb and uh we go through weighted batch pre-processing here because that's
something we think that everyone needs to be up on again totally free site uh all we ask is for you to register and
you'll get some of our emails but you also get all the data and all the process icons here so
yeah again we we just uh we love what we do and and we've we've made so many friends
uh you know doing this and uh our audience that we have is is pretty
incredible but uh i i does anybody have any questions
yeah i mean that you know it's it's a great it's a great resource out there um
and if you haven't taken advantage of it definitely take advantage of it um it's it's you know and if you if you want to
win a free masses of pics insight tutorial you could have a chance to do
that almost every friday night until the end of the year if you go check us out on the astroworld show on friday nights
at 8 we do it at the end of the show so you can either win a masters or pixel insight
free workshop or possibly an ip for ap uh yearly years worth of subscriptions
because the yearly yearly service so so definitely uh come down and check us out
um we got some upcoming guests real quick and i know we're we're short on time um
but um we got last week if you didn't check it out last week with richard wright um
he was just awesome on the show he did it from starbucks it was great uh this friday we have eric coles who's an
astrophotographer and if you haven't seen his stuff check him out on astro bin he's also one of the um one of the
people at uh the astro imaging channel he's one of the one of the hosts there
um may 20th we're gonna have maxie who's on the show here with us tonight um and
then we're gonna have chris woodhouse who's the author of capturing the universe on may 25th which will be a
taped show um and then we're gonna take the cherry springs break because i think uh i'll be going the cherry springs so
um that being said um i wanted to show a little bit of video uh but we won't do
that tonight because i know we're running a little bit short on time but uh um thank you so much for having us on
yes thank you thank you so much that's great um i think that you know the masters of pix insight it's
it's pixel insight university is what it is yeah right it's awesome absolutely
you know so uh it's definitely um you know worth paying uh to get all that
incredible uh tutorial because it's lots of work to you know if you've
ever taught anything uh yourself you know how much work it is so um and let me tell you we've got some
users that are putting out some great images like i said we have a private facebook group that's tied into it and
uh you know we call it the hive mind because if someone's having problems they get on there and say this is this
isn't working and we might answer it or one of the other uh you know subscribers so it's a great
community and and uh we uh you know we appreciate you having us on to spread the word this evening thank you thank
you so much thanks a lot scott okay thanks a lot thanks guys thank you
bye okay so um really wonderful and a great resource
masters of pix insight up next is marcelo souza marcelo is in
brazil he is a uh he's a master of astronomy outreach
a great educator very inspiring uh he has a background as a cosmologist
and he makes learning astronomy fun uh for his students but he inspires them
to go to take the next great leaps in science and so marcelo is also the senior editor of
sky's up magazine which is a free global astronomy magazine that you can get at
explorescientific.com up and so marcelo you want to come on
hi how are you nice to meet you invitation thing and
here we are now talking only about the eclipse you know i don't know if the other places it's
happening the same thing but for us here it is a very important moment and
i'm talking every day about cyclics here
i am remembering also the activities organized here
i will share my screen thanks for the invitation thank you marcelo thank you and let me
share my screen here
what is something something that i'm ever looking is about the solar activity
then today we had another x-flare
last class solar flare and again again we had problems with the radio
blackouts it's third time third time i believe in two or three weeks at that
time that this happened here i i think that soon maybe you're having a big
event and this is great resource um
spaceweather.com is too yes it's fantastic and they received this today
this happened today again and they have a radio blackout during one hour
that you need to be concerned about and i don't know what will happen but see just
the sun is very active now and we were waiting that this
will happen in 2025 and it happened now let me see what you
have then as we are talking about the eclipse
in meantime in many places they are asking us to talk about the sun
almost every day i'm talking about the sun the process that's happening
inside the sun what happens how that's ending with you
that come to us
something that for me was one of the most important experiences
that i had here our protection the magnetic fields and this is something fantastic it's not
from me it's from nike hauling heads now
this is the moment that people are looking for for having some relatives and i had the
opportunity to make amateur move
about the the solar eclipse in 2010 that i
had the opportunity to to see in argentina in the south region of argentina that's
why [Music]
when i arrived there i've met a lot of people in a hotel
oh yeah and uh i was preparing to
to go to the eclipse and didn't find any car available to go because you need to
go to one of the mountains here you have a mountain here and you need to
go 1000 meters well high to see the eclipse because you have the
on this mountains in front of the uh
in the here you need to go in this place here to see the eclipses
and we need to find a car to make this level it was very difficult because they
rented out the cars then we found one of the car one car
and you had the opportunity to be in front of everybody that was there to
see the eclipse because they uh the travel was to be
near the border of the mountain
and uh as a material i use my own camera
and you see i it was possible to require the
total eclipse of the sun in this moment here is a place
from where that observing the eclipse it's very cold it has minus 10 grams
10 degrees celsius so it's very good for me
and it is a place that i had the opportunity to observe the eclipse here is the clips
i required with my camera it was very cold i i kept my tripod in the inside the car
maybe i use my hand to make the move pretty good though
and the diamond hinge it will be possible to see at the end here of the
soul it is moving because my hand is moving
it has one of the most
i was with my wife there that's great and then trying to get
ready you can share an event like that with uh someone that's special to you you know
that's fantastic fantastic experience for me and now you can see the diamonds
ring that's one of the most fantastic moments that
yes it's a fantastic experience for me
wonderful and here you have the jaundice here
now we are preparing for the total solar eclipse
that should be our opportunity to see an eclipse here tips the next one will be possible to
see here only in 2025 as we will see this is our
time is here we will begin the partial because we have
our time zone is minus three in green each time then it will be at
see 11 25 27 pm that you begin the partial eclipse
and the we are preparing to observe from six
different seats near us being seat we have telescopes in six seats
and it is the biggest event that we organized this was the
last one that organized in 2018 you have more than 5 000 people
the eclipse with your eyes in a bridge here that cross behave here in downtown
you can see it amazing you have a lot of people and it was transmitted live by
a local tv for i believe that 20 sits near us
and here is the report interview
they participate live showing the eclipse at the end of the eclipse this is the age of the
the event that organizes here we have a lot of people
and you have half of the people here that participated during the eclipse
i i show here this is live my tv
here you can see a lot of people there nice telescope there they they stayed there
until i my wife here with my daughters
a lot of people we had the opportunity to close the
main bridge of the city during three hours it was fantastic here
it's wonderful to see so many people enjoying a celestial event
i had a lot of people there such fantastic but before this
we organized another one in 2015 that was in the main public square
of our city it is the same place where we organize the main event for the
observation of this eclipse we will build a headquarters of our group to
coordinate activities in other seats and this is what happened in 2015.
let me see if
[Laughter] the best and it had more than 2 000 people
participating
here you need to have muse you know to make the surveys yeah this time i think that will not be possible because
it'll be very late
it's wonderful it's a big celebration here
so marcelo you're expecting us this moment of the total
oh yeah you're expecting a similar sized crowd
this time now i'm on the show
in the yeah are visiting schools to talk about our projects and to talk about the
eclipse in the spirit this was the activities that we had uh friday
last friday we have more than 100 students participating
and today yesterday and today in this school talk again about eclipse
we are visiting many schools about disputes and i hope you had helped us and you can organize a
big event and the uterus meets live and they will do our best to be in your
broadcast so it's quite thank you thank you so much
a very special moment i hope everybody have the opportunity to see the total eclipse now
marcelo how many people are you expecting to be at your event this weekend
uh we are organizing six seats different seats right okay and here and in our
city that will be our group main group will be here yeah
it will be for us it will be very late but you are waiting more than 2000 people there
wow one thousand one thousand one thousand okay one thousand one thousand still yeah but we don't know maybe you have
more i don't know because the image that i show the of the bridge
we asked them to close only one line of the bridge when we arrived there we
have many people selling popcorn hot dogs and they close the algae bridge
and they have a lot of people more than 5 000 people that was in the bridge observing
the eclipse oh it sounds like fun we don't know what to happen because you'll be very late here right we'll finish
3 a.m man it's valuable yeah 3 a.m and it is from
sunday to monday they begin to work monday i don't know but we expecting more or less 1 000
people they will turn you off all the likes of the republic square wow and you
have policemen there our telescopes i don't know what's going to happen man this will be valid but i hope that many
people participate yes me too i think that we will transmit live and you'll do our
best to to join your broadcast live yeah wonderful thank you michelle i'm
looking for um people that want to broadcast live their views or their
experience uh or to give short presentations on that night
um so i've already put out the rsvp for that if you're listening the audience you want to join uh you're in the path
of the eclipse uh certainly get in contact with me um be very happy to put you on the
program well up next is uh bob fugate robert q fugate as you might find him on
the internet he is someone that played a principal role in
in laser guided adaptive optics technology for large
telescopes but he is an amazing amateur astrophotographer
uh and uh he applies his uh his scientific mind to
his images but he also has this really amazing artistic side and
i think that the images we've seen so far in his uh presentations i think this makes the third or fourth time he's been
on global star party and i'm so happy he's sharing his work with us
bob it's all yours okay um thank you so much scott and
um i'm uh i'm happy to be here i'm i'm just
i was looking at jason's website uh after last week and
or whatever the last time he was on and i'm just i'm completely blown away by
by his images and so so i consider myself
a learning amateur compared to what he's doing
and when people tell me i've got great images i tell them you don't get out very much or
very far because there's a lot a lot better astrophotographers out there than me
anyway let me share my screen and i i have some sad news to start with um
let's see i don't know um i don't know how many in the audience know of david
freed he um he is the
um free world's or the world's expert on atmospheric optics
and unfortunately he died last week on thursday and he was 89 he was a very good friend
of mine and we worked very closely together for 40 years
seems like forever so i just wanted to give a tribute to
him uh here i tried to find some photos and i i think i have some others but this one
was made in 2009 and it's appropriate because it also has daryl greenwood in it
daryl greenwood did the seminal work on understanding
the speed at which an adaptive optic system needs to operate and he has a frequency named after him
the greenwood frequency so here i am
standing between the shoulders of giants so to speak and
i feel very privileged to to have been able to work with these folks any rate um
uh i'm i'm really saddened to um to learn that david has passed away and
you know there'll be hopefully happier times okay um
i wanted to talk about a couple of things one these collisions and
and you know it's generally thought that um probably an asteroid was responsible for
the uh cretaceous extinction event of about
65 or 66 million years ago and so every time we see
a meteor or a close approach by an asteroid it
brings all that into perspective neo-wise came to mind and i took some
images this one on july the 7th 2020 as it as it visited albuquerque
in the early morning hours and it's kind of a nice photo because it has lots of noctilucent clouds in it
and over the next few days before it became an evening object i went to the east side of the sandia
mountains and and used a property over there of a friend
to get some better pictures uh one one of the things that um
i wanted to get and i never really was successful was this really long tail it had
this is not a very good image it's just stretched be
beyond relief and um but there there was a lot of stuff
really far away so it was quite an amazing comment and even though it didn't seem to
get a lot of recognition it um it really really did intrigue me
and i here's a here's a tripod mounted iphone selfie
done with a timer while i was at my friend's place and i just found it amazing that you
could take a photograph and see the comment with a cell phone right
um and uh i tried to get some um you know comet only kind of shots and here was
one of the one of the better ones i got there's quite a lot of color here in the iron
tail and i don't know how well it shows over zoom
and so so um as an evening object just before it disappeared on uh this was
july the 16th i had only one opportunity because my wife was having hip surgery
and i had one night to go out and there's a place uh in the desert managed
by the bureau of land management that's northwest of albuquerque
about 30 miles or so and it's called
the white ridge bike trails in the blm system
and you'll see in a moment why it's called that but here's a shot um
fairly wide angle um just right at sunset
and then later and and all these clouds kind of added to the picture you always say that when
there's clouds you know while it's a feature but a little while later when it was darker
i was able to get this shot and if you can see the white in the picture
here in the landscape that's where this area gets its name of white ridge
this is actually gypsum and so this area um
used to be a sea and um you know this uh
this is i guess it's um calcium sulfate hydrated calcium sulfate
so um you know geologists tell us that this used to be an ocean
and in fact just west of here
um was the largest dinosaur ever found the longest dinosaur ever found
and his and his name is uh seismosaurus um
so you know i'm out there in the desert and i'm thinking um
this this would be the perfect spot i better keep my eye out for a dinosaur
and um so you know if you were a dinosaur and you saw this giant object headed toward
you what would you do well you'd run screaming and that's what's happening here
um so this is this is supposed to be a joke folks uh but any rate um this is the perfect
landscape for dinosaurs and and we'll talk a little bit more about that uh
shortly um or at least about this era
in terms of um you know the age of the earth and stuff
so in terms of uh small impactors that we heard about earlier
um here's a here's a shot i did uh again this was
um just east of the sandias and i'm looking south here this is the
geminid shower in december and i thought i'd try for
you know looking away from the nodal point of the
of the meteors and uh at that and when you do that and look near the horizon they're all
parallel so this kind of looks like you know we're being the earth is under
attack here by by meteors
and then i have one more to show and this one i took in my backyard just by accident
i actually had a new lens and this was earlier in december
it's going in the right direction to be a geminid meteor but it's just early
this is orion here's uh the great nebula here's the belt stars here and
beetlejuice is up here sure um and uh in this in this case i think this was
a 60-second exposure
oh we lost him well you lose me you're back you're back now
okay yeah i don't know what happened um so what you see is the uh winds at high
altitude causing this sort of vortex with the stuff being blown off
and um so did my screen stop sharing yes
everything stopped oh dear that's i don't know what's i don't know what's happened let's see
it's called the internet uh
so let me try again was remarkable is that you could just come right pop right back in you know
so that was good
i'm not sure what's going on that last shot uh bob what what size
lens did you use for that what's that now what what size lens did you use yeah this was a 100 and this
shot of the meteor let's see i'm not sure what why i can't
oh boy cheer again i've tried let's see
it's coming there you go
okay is it back it's back okay so this was a 105 millimeter f 1.4
sigma art lens wow okay and uh it was it was wide open at f 1.4
uh this camera was not uh an ir modified not a you know an astro modified camera so the
so the h alpha stuff here at the here in the horse head and you know barnard's loop is not very
and i haven't tried to stretch it out in any particular way
you'll also see all these little streaks here which are geosatellites uh
i i i don't know if you can see them but you can see um they're kind of like
all over the picture this one here may not well it's about the right length so it probably is
okay um so um i thought the other interesting thing to
talk about in terms of the geology is um
the grand canyon uh and i and then three years ago about three years ago i had a great
opportunity to go down the colorado river
but before i get to that let's talk just a little bit about the geology and and i don't really know much
about this i'm just you know parroting what i heard
on my raft trip as well as what i've been able to get off the internet but
uh the grand canyon is just an incredible place for seeing
back in time through the through the crust of the earth to about 1.7 million years billion years
1.7 billion years 1700 million years
and the first layer here is uh 270 million years so
that extinction occurred you know near the surface
and that's why i guess we we find dinosaurs not very deep um
but the um uh the the most incredible thing was
being able to go down the river and see all of this unfold the further you go down the river
the deeper you go and and let me mention this great unconformity
this is a this is a gap of 1.2 million years that somehow disappeared in various
places so this this layer of rocks um
you know there it just it doesn't show up in some locations and you go from
about 600 million years to 1.8 million years
and so there's there's this 1.2 billion year gap in the in the history of the
of the geology and i'll i'll show you a picture of that later so um
the the river starts at uh glen canyon dam which forms lake powell
in northern northeastern arizona and here's somebody fishing
and just below the dam the the canyon looks like this
so uh in 2019 in late august i was invited
on a photographer's raft trip by a fellow this fellow here dewitt
jones he's a former national geographic photographer
and he he's just an incredible person his mantra is celebrate what's right
with the world and it's really a refreshing philosophy yes
we had two rafts that were motorized and here you see the picture of the crew
this was the senior expedition captain he had been down the river
273 times and this is a new pilot
a young lady who was extremely good and these are the other two crew members
and here's to wit shaking hands with the with the new captain
but these four people cooked three meals a day for us we had lots of room because each of
these rafts was designed to hold 16 people and there were only 16 of us all
together so we had two giant rafts with lots of room for equipment
and i just if you've never done this trip
put it on your bucket list because it's just absolutely
life changing the light in the canyon is is just
awesome yes um and so this is in the upper part of the canyon where
we get into that that first stage of rocks that are about 600 million years old
and we spent a lot of time just drifting motors turned off
just having the current carry us along listening to the canyon wrens i mean the
silence was just awesome so here's an example of those rocks that
are the underlying oldest rocks these rocks are 1.8 billion years old
um [Music] it's just so here are some more examples here we're now now there near the
end of the trip about um 120 miles down down the river
i tried to i tried to not take any pictures without the river in it because the river is really what the
grand canyon is all about so here is a slot canyon and we took a
lot of side trips here's a slot canyon and this is one of the places where the great
unconformity appears you can get a get an idea of the scale
if you notice the person walking here uh and there's giant boulders in this
canyon that get moved by water rushing through it so it's not a place you want to be when
there's a thunderstorm and on the left here you begin to see the vestiges of the
great unconformity and here's a closer up view of it
so the rocks that are in a horizontal layer are the young rocks and the rocks that are
in a vertical layer are the old ones now you wouldn't know this by looking at it but the geologists
know know how to do this sort of thing and they tell us about that so
here i've tried to put some graphics on this to show you that this line of demarcation between
these rocks and these rocks is what they call the great unconformity
i would call it a discontinuity being a physicist and a mathematician but that's
what the that's what they call it an added bonus on this trip was
this young lady got to go uh her name is tayana
and the a couple that was on the trip of two photographers
were able to get her on the on the trip because one of the persons uh had to
cancel and um she grew up in the inner city
of detroit and uh it's it's a heartbreaking story
which i won't go into but um they got her on this trip this was the
first time she had been out of detroit and first time she'd been on an airplane of
course she was just enthralled by this trip
and there's lots of good news about her future but i thought it quite interesting
that she really thought this unconformity was an amazing thing and
she put her hand across it so in my remaining few minutes i wanted
i want to show you some photography at night um i did not get much sleep on this trip
it was eight days seven nights and i was up most of the nights and
of course all during the day trying to you know survive not drowning
in the rapids and so forth um but the light in this
in this setting is just absolutely awesome uh here here's a couple of shots at
twilight you can see uh kind of the blue sky there was there was a partial moon on some of the nights
so i have both you know with and without moons this shot was made in morning twilight
the sun was going to come up behind me it was still probably civil twilight
and i'm i'm laying there in my sleeping bag looking at this wall of rocks with the stars above it
and it just kept getting more and more awesome and finally i got up and tried to take a picture
but you know the visual immersion was just absolutely incredible
in the middle of the night it looked more like this when the moon was out so um
and then in the darkest part of the night it sort of looks like this
um just an incredible experience the grand canyon is of course an
international dark site and um rightly so
here's another twilight shot um so i had hiked uh quite some ways from
where the campsite was where we camped with the with the rafts
down to get and you'll see the you'll see the shot here in a little bit of the milky way in the canyon
um and when i was hiking back in the morning
i saw this shot with the moon here's the crescent moon here
and there was you know this beautiful color in the sky from the sun rising
and i just you know i just had to stop and try to take a picture i
started and i set up and i suddenly realized i didn't have the river in the shot
and then i moved to get the river in the shot and i didn't have the moon in the shot so i moved again
and meanwhile it was getting lighter and i was thought i was going to lose the shot you know i i felt like um ansel adams
shooting that moon rise over hernandez shot when he was describing
racing around trying to get the shot before the light went so um
and then here's another twilight shot this one in the evening and these mountains
were just on fire i mean the sun is way off to the right
here in lighting up those mountains and so i couldn't i couldn't resist
making a composite like this when they
got dark enough to see the milky way um this is kind of this is kind of what
showed up this this turned out to be an astronomy picture of the day by accident
because uh you know one of the astronomers i can't remember which one i had posted this on
flickr i think and he contacted me and wanted me to submit it
so that's the best kind of astronomy picture of the day experience
absolutely so here's another um you know we we camped at night and um
this is actually teyana's tent the young lady from from detroit
and when she first started at night she was she was kind of afraid and so she kept her light
on all night and um but i really i really kind of cherish
this picture and she spent quite a few nights up with me
seeing the night sky for the first time and you know when i pointed out
andromeda that she could see with her naked eye she just couldn't believe it
and this was just was just a huge huge experience for her
beautiful so you know i kept hoping that we were going to camp
every night in a place my vision for this trip was the milky way rising out of the you know
central part of the walls of the canyon and on the second well
i'll get to that um [Music] the river is green and
it's it's 55 degree temperature water
so if you get too hot during the day you just jump in for a while and it instantly cooled off
but at night you're treated to just you know incredible views of the sky
and uh here's cassiopeia here's andromeda actually right here yeah
and then when the moon comes out um you see more of the landscape
and here are the boats tied up the rafts tied up and
if you look closely you'll see there's people sleeping on it that's the crew
they slept on the rafts every night and there's the moon
in the beehive cluster but even when the moon is out you see
the milky way oh yeah that's testimony to health transit so finally
the the second to the last night we've we found a location i had to hike
like a half a mile to get to it but i was able to get the shot that i
had envisioned and and here it is [Music] and
then i changed lenses you know the milky way had rotated
this is uh 40 millimeters instead of 14 and
just absolutely mind-blowing yes so um that's what i had to offer
that's people uh are
i guess the only term we can really use is mind blown it is those are amazing
landscape shots with the milky way and
you know i'm always someone that's very in tune to composition in photography and you're mentioning
vansel adams uh really uh it rings true with me as well so
uh as uh somewhat of a student of ansels he would have really enjoyed your
photography um wow well he would have thank you so much um
i appreciate that absolutely bob thank you so much for coming on and
uh thank you for having me absolutely absolutely it's our honor thank you
okay uh so up next um is uh
uh maxi follari's maxi has been on many global star parties
so many now that i don't even know how many it is um but i would say he's now
become a uh definitely an ambassador of global star party and
he is an amazing astrophotography and astrophotographer in his own right lives down in argentina and uh
shows people how they can make images with all kinds of different equipment including like a modified cell phone so
um maxi uh what's happening tonight hello scott good night everyone thank
you for inviting me again and you know the last gsp it was
my first anniversary to be here with you
so well goodnight everyone what i want to show
you tonight is what i've been doing this a couple days ago
let me share my screen okay
all right do you see it yes excellent
so basically what i want to show you is that i
have this new gear that i
this is a a a lens to [Music] to get a more a field of view
i think it's a to 5 to 22
and i want to i i have to to get practice with this
this lens because it's really difficult to get focus and well i i want
to work with my sets of duo but also with my dcr camera
anyway i was practicing with my dog sophie
taking this picture she was super pretty nice
yeah she was watching me like what are you doing man i want to get inside
but well i i was only practicing with taking single shots
and then a couple of days i started to build this kind of
cover to put it a in front of my newton telescope
this is a that we say a rubber eva
with five millimeters of um [Music] of size uh
and it's already flexible but when you
get surrounded it's really really tough
so i want to to build this because i have
some interpretation with the temperature and
the humidity of the environment so uh to get more protect the mirrors and
the lens in the uh camara corrector
so i i tried to be more a detail
to to build this and and i was really happy to
that it fits really good but i realized when i get to
to get a practicing it was really long so i had to
to short a little bit but anyway uh
this picture marcos santa rosa sent me a couple days ago of
how it looks the observatory in alberti
this is at night you can see and now they have lights outside to to illuminate the place
and and surround around this place it's all
formed it you know it's like a um a lighthouse in the middle of the darkness
but of course when we go to here you can turn off the
lights and and then start to watch
this is the backyard you can see they have led slide but it doesn't
interference you can see is pretty dark and when you watch the
outside and well you can see they put a air
conditioner with cold and hot air and because they
get cut in a warm area
we we put this heater water
this i think is electrical and also we have the bedroom the the toilet
and the bed we we use here in the south davidette i don't know if you know what
it is this is to wash your back
[Laughter] so well
they built this little kitchen to to everyone who wants to to wash dishes
or prepare some food uh this place is going to be really really
um good to to stay in there
so days ago i invited to a friend that he wants to
do some pictures of a really good skies because he's
nearby nico's city he's from longshams
and he's he has a a really pollutional sky so
i invited to him he would say yeah i would try to to to travel so
we met here in chirico and and ran away to alberti and
here's him he's a working with a eight inches a f5
telescope with an nqc six mount
and here's mine with my with the the cover that i build
and my car and his car illuminate and here you can see the backyard of the
the observatory and you can see the lights it doesn't of course it reflects the world but
it doesn't bother too much to you to be here because
it's only reflections not getting to you right
so [Music] this is the the next morning that
i was taking pictures to to see how it looks like it's
in almost in even the past a year it changed really a lot
and i i told marcos to remember that
of course they built this fence to get protect the area you can see
behind this fence is the the crops a farm that they
turn away and beyond that is the farm of the
of the demand who helps nico to get out the the road the last time
and here's us when we finally finally finish our our day
and returns it was the the sunday almost yeah you know he he was really really
happy because he loved to to see the disguise and
he wants to try the his equipment in this place or and of course he
he had to to work with his objects
and well here's a picture that i did uh with the that lens that i show you and my dcr
but in in a single mount
that i work we can see here is calling enablia
i i had a really bad problem with the focus my battery died really quickly
and it was like a test but yeah it's a single shot of i think
three minutes yeah it looks great and i really love the
the field of view you can see here this place is what i had in my back here in my
background is the the same area and
uh this is another one this was in five minutes
but i was struggling with the focus
i i had to get practice because my this alert it doesn't have live view so i had
to do it trying to watch it with my neck you know 1980 degrees
and now it's almost possible and practicing only here's the raw fucus
region i want to try to to see the field of view and i really loved it
because i started to have the reflections of the stars
behind the darkness nebula also here with a antares star
a m4 no m or m22 no no m4 is this place
and of course these are the i'm glow of the camera
and well uh what i want to present uh
and what i was doing taking pictures in almost all night uh when we when we went to
advanti it was the galaxy m83 i was taking pictures like almost five
hours i think and but i was fighting with the wind because
he comes from the north and and the the following and the guiding is
it was like shaking and i had to
trash almost more than the half pictures because i
only could stack two hours of integration and
but anyway i could have a really good data
let me show you this is a single picture in this skies this is a 100
percent of full resolution and this is m83 with these tiny galaxies
stars and almost a another tiny galaxies in the back
of of course a red dots of pixel hot pixels
and well uh this is the the field of view that i had with my scope and the only place that i was a
shooting so when i stuck the
and try to see what i get in this two hours of stacking i have this
this is a um auto stretching but with the screen
traffic function and so it's really shiny and
of course i could have much more data you can see here that there are these
two galaxies but yeah here we have another one
more down i think it was another there's one there
right here another one and here's another one
here in the in the left of the one here down there's a couple more
you know there's really far away here's another one and
another one and it comes popping up so when i process
this picture i [Music] get this
i really loved the the kind of colors that i had
and of course i lose some kind of data in the background i think
with the galaxies but the principal place to to get the spiral arms the nebulosity
the colors of the inside of this nebulosity and the core
uh it really blows my mind you know i remember when i
i taking pic i was taking pictures with my cell phone to this place uh with my modified cell phone and also
with ocular projection and now getting this of course is a huge
advance but
anyway checking this with a cell phone it's a huge advance i think also so
um well this is my my picture that i was only working
these days and i want to try to get again [Music]
12 30 soon now we have i have the the total lunar eclipse here
i think we will have uh not too very good weather
is going to be really cold uh and scott i will try to
to be a doing some a live broadcast
but maybe a little moment i don't know what i could see okay
from here but i'll try to to do some some connections
so well uh thank you
thank you thank you max thank you guys and i hope you liked it yeah thank you so much
impressive galaxy maxi amazing picture good that's ssl thank
you so cesar uh it's great to have you on again um yes
yeah so you're up on your balcony uh with your telescope and um
how is looks to be maybe a little windy is there very much wind
ever ever if i go to the balcony the wind appears it's magic
yes yeah it was perfectly calm before right absolutely yes yes but gladly
in the evening um when i go to the balcony now well you can see some
clouds but i i can touch uh with the
explore scientific and natural national graphics series over a very
right to see old mode um tonight it's unable to to
take some pictures of the sky but something that i can i can make
maybe [Music] ahead in the next week if i have
if we have a clear clear night but i using a very simple
very sample and cheap uh totally
uh cam um in the field that you have uh it's
very that's something that is interesting uh is that this optical tube assembly is very easy
to use it's very easy to to point the object um
really something to enjoy for the moon for planets or or something
of uh deep sky and like never support from the city or
some uh blablar or open clusters
i sh i can show you some picture one picture of the moon because i i
can't show you a live image because uh the moon now is fast behind
[Music] a big tower but okay
yes yeah 15 minutes ago 15 minutes ago
i can took some pictures
and really it's easy to to have a grey
pictures
with some details yes [Music]
so this was taken earlier this evening right uh no 15 minutes ago 15 minutes ago
because in the evening was totally cloud yes yes no no now was now
was it 15 minutes ago yes
the photographer's doing a good job too it's absolutely easy no no no it's not
my my my capacity absolutely no
and it's a great telescope but unfortunately i can't i can't
use for db skies image but i drive
me when i receive one for me the excess 100 i can i can
try to to make some exposure with this the same camera because uh actually many
many uh guiding cameras cameras that
the planet cameras actually are more sensitive like nico use
actually or you know because um sensors like uh m i m x
290 for example from sony are excellent for guiding and it's great for
kids or for for people that are starting to make some pictures in this kind of telescope with
wide-angle field of view it's an excellent option
uh to try deep sky image from
from modes that are
smaller um in this actually i have i tried this because
it's but it's not gray it's only for for makeup five or ten seconds of uh in each exposure
but um if you have an equatorial mode like a exodus 100
you you have a very small portable observatory with a
camera that is very easy to use a planetary camera
a very small telescope and cheap and amount
that is to use a small camera and
objective or this kind of telescope or maybe something bigger um
work really [Music] you have a lot of fun uh because you have a in a small package
yeah really affordable don't have to spend a lot of money right absolutely absolutely
and maybe for for next week i can show you some
try with uh maybe open clusters or something easy
because this kind of mount it's no more that
five seconds or ten seconds maybe but like the system have a very fast
uh racial focus register where you have maybe four
point thirty i think that is four four point four no
more sure um this is this is that is great for this kind of
sensors where you have an optics that is very fast to make
[Music] pictures where do you have in few seconds some image and you can
get fun with a very very small telescope
great well this is my presentation it's very good sure but is it this is the first time in the
year from the balcony you know ah
wonderful wonderful so what's your hand what's ahead for you um uh cesar you're
working still on the restoration of the historic observatory complex is that

within safe um really the the constructions
because they the size of the things is huge and all right we need to have yes
they say it needs to be safe yes first of all it's safe absolutely yeah safe

um and of course that i don't like this because it's actually that we are using
for for cameras and eyepieces um
but we are going to restore the
newtonian reflector of 14 inches um we are to see more
well we have an h alpha telescope of i think that is 90 millimeters yes 90
