Global Star Party 103

Transcript:

movies and loving it awesome great
she must love retirement yep
it's too bad the whole world can't be retired
one day it will yeah i'm looking forward to seeing how that
works out
peter are you retired now yeah yeah diane and i both retired in 2017 and actually she retired a little
earlier than i did but uh you know i i mean i was lucky being a teacher and
loving what i did i didn't really feel like i was working at all anyway yeah
so these last five years since i retired i'm more or less doing the same thing i was doing before except i don't go to
class
some people told me that once you retire you work harder than you ever did in your whole life
there's certainly more passion that's that's for sure
not me you're still at work yeah
i don't think i've ever seen david work as hard as since cobit started uh he has done a an amazing amount of
presentations yep and today's presentation
gentlemen is going to be number 35
wow presentation number one which was in the spring of 1960
at rosland school wow that's cool congrats
thank you that was your first astronomy talk this is three thousand and change two thousand and twenty eight hundred
machines yeah congratulations thank you it's uh it's a lot of fun and
i enjoy doing these and each one i especially enjoy this with this global star party
it's a large group and it's but it's a very informal group boy scotty it set it up
i hope that you know that's that was the hope that people would just enjoy being here because uh
you know uh when the pandemic set in and everybody was on lockdown uh you know
everyone's sort of i think they were sort of starving for um
you know com you know the friendship and the exchange of ideas and everything that you can only find with amateur
astronomers right and so uh a lot of amateur astronomers even if
they only meet each other once a year or something like that those friendships last a lifetime yeah
you can't really say that about a lot of other things you know well
colonel you know the way i introduced you to peter was largely in jail but
the night i first met him so many decades ago he actually said those
things in a luxury david thinking some stories outlined what he wanted to do and he's done it
very proud of you it's a great story
i have to say though we've done very well with the format i remember i don't know what time it was but we did that comment panel and you talked a
little bit about some of your experience and we kind of shared some photography and stories and all that
i remember scott had a story about turning a dobsonian into a water bucket basically chasing
that's right but that that to this day is one of my favorite global star parties i felt like i could have been sitting in
anyone's living room just uh you know sharing the best stories we had from the hobby yeah
well it's kind of it's kind i imagine this happens at most star parties where you know there's a place where
a lot of amateurs maybe they're not observing right at the moment or they're in between observing
sessions with their telescope and they'll hang out and talk you know about all kinds of things you
know what i do find is that they often don't have a chance to give a uh
a short presentation you know there's presenters at big star parties
um you know and there'll be a keynote speaker and maybe a few talks before that um
but uh you know having um you know global star party with about you know 15 to 20 minute
talks uh you can get quite a few on one evening you know and we've done them
every week for a couple of years now and uh hello kareem
it's been a lot of fun kareem how are you hello everyone i am uh scrambling how are you
i was scrambling too i was scrambling too i just got home from a full day of
teaching again and uh it's been a really good week but a really long week and uh
time it's a new beginning there you go it's a new beginning that's right
so are you ready to go to starmus kareem what's star miss i've never heard about
it you've never heard it yeah yeah i'm excited but i am uh i am a
little bit bewildered on how i'll get ready for everything but uh we will we will right and i'll be seeing you on
sunday yes yes we're looking forward to that uh my son is giving our public event this
this month it's exciting all about mount wilson
so very important i uh you're gonna have to be careful here scott uh the canadians are getting
close to outnumbering the americans on screen peter
it's part of our plan right karim i i've i've been keeping that silent but
i guess now it's out there oh don't worry they don't they're not listening to us anyway
[Laughter] you'll see scott's gonna be an honorary
canadian uh the astronomical league has come in here in a couple of years and uh
yeah my best friends in the world are from canada so yeah that's the good news most americans will get to be honorary
canadians anyway there you go there we go you remember you remember uh the movie
canadian bacon oh yes yes oh yeah
conal have you started classes already yes i did just started on monday still
working through the start of things but it was it was as smooth as it could be i think excellent
the chaos was uh in wrapping up the summer courses it was eight credits in six weeks which worked out to the equivalent
workload of 21 in a normal semester and that was nasty yes now things have settled down oddly enough that the
academic year started and i'm i'm looking forward to it certainly the structure actually gives it a little bit
of sanity it does it really does
michael's here or can't wait to see what he's got and john's got a quiz ready for us uh that connell's gonna win as usual
so you know right so i saw my name on the gsp 100 list i was
pretty happy to see that a couple weeks ago
but we had a good event we had a little show uh just about an
hour or so ago with annie and annie found these crazy questions you know
about astronomy 10 crazy questions but i'm interested with the group that
we have right here what is an aspect of the universe or astronomy that just
absolutely blows your mind what would you say peter
well i said if you had asked me that question 30 40 50 years ago i would have had a fancy answer but i think i'm
getting to the point where i've seen everything and i'm so jaded nothing nothing impresses me anymore so now i
have a hard time answering that's so sad
my heart just broke pitiful confident you know one of the things that amazes
me is that you look at you look at the current uh writing about astronomy and all
through our lives and even further back everybody always says this is the golden age of astronomy
yes it's been the golden age of astronomy since 1609 yeah i would agree with that i mean i i
love that i'm not i'm not i'm not criticizing i think that's wonderful yes but it kind of makes me sort of feel
like yeah yeah yeah it's going to be great there's going to be you know the universe is unfolding as it should
[Music] and peter if you ask me the same question scotty
of the process of observing not more than goals more than the pictures more than the
comets it is being out under the stars looking through a telescope or watching
for meteors that is what still gets always
that's cool how about you michael
are you are you there michael oh me sorry you
oh yeah you know there are so many things i um i am fascinated by the
the kind of quantum edge to things that we've run into in the last
few decades a few years for the popular science people like me
who aren't that brainy just the the
concepts of deep time have always fascinated me and and when you
run that back to the big bang and and and watch the expanding dimensions and
stuff it's just mind-boggling i i i love it i i love to look up at the night sky
and and think that that's the the fingerprint of all these things that are going on it's pretty fun
right that's great well it is time to get started but uh
i think i didn't ask john or kareem or connell this question yet but uh as you give your presentation maybe uh you
could start with that so that's awesome uh so here we go uh welcome everybody to uh
if you're signed on uh watching uh from around the world um our we're at the 103rd global star party
new beginnings and it's the theme and we are
we're very happy to be here with you tonight
[Music] with all that man has yet to learn about
the world beyond his own much that he now knows can be traced back to a polish astronomer born 500
years ago his name nicholas copernicus the father of modern
astronomy who formulated the concept that the moon and earth revolve around the sun
rather than vice versa
nearly five centuries later his name has been memorialized in a new space telescope designed by scientists at
princeton university in the united states and university college in london the princeton contribution was a large
reflecting telescope for detecting invisible ultraviolet radiation
university college designed a new system for monitoring sources of x-ray energy
in outer space [Music]
orbiting astronomical observatory copernicus was launched from cape kennedy in florida on august 21st 1972
enclosed in the tip of an atlas centaur rocket it was the largest and most complex unmanned spacecraft ever sent
into orbit from the united states scientists and dignitaries from poland and england attended the night time
launch
from the earth an astronomer can see millions of light years away but only in the range of visible light
cut off from him by earth's atmosphere are the ultraviolet infrared gamma and
x-rays containing secrets of how the universe was born in the darkest reaches
of time and space 500 miles above the atmosphere
conditions are ideal for probing these mysteries that is where copernicus is now on
full-time duty using its solar panels for electric power to find and lock onto
many stars and dust between the stars where stars are born
ground stations around the world receive transmissions from copernicus and relay them to the united states
astronomers everywhere are pleased with the early results material needed to form new stars has
been found where none was thought to exist at least one star system is rotating at
a speed that increases almost daily other early observations remain to be
interpreted as the eye of the new copernicus continues its studies of invisible clues to the creation of the
universe [Music]
this is scott roberts from explore scientific and the explore alliance and uh what you just saw was a 50 year old
science production uh that was put out about that uh space telescope and uh
we've had uh you know a number of space telescopes up uh not just the hubble space telescope
but uh several others and um uh you know and we are going there's a
whole uh legion of new space telescopes that are on the drawing board now and uh
so uh you know with the combination of space-based and ground-based instruments
um for the professional world and for the amateur world uh
amateurs doing uh uh ongoing investigation of new discoveries uh new data that's coming
down you know we are all uh
improving scientific literacy around the world and uh we're on a big adventure
and so the theme of this particular presentation was new beginnings
and it's because you know we are at a point now where we are looking so
far back into time with the james west space telescope that it's causing uh the
cosmologists to rethink you know the origins of the universe
and so it is in a way new beginnings all the time in the world of science
so anyhow i want to thank you guys for tuning in and i'm going to uh turn this over to david
levy who's once again brought on a special guest david well thank you thank you very much and
today i'm introducing my friend peter trevity who is going to be accompanying me on
one more time on our poetry of the week peter i first met him
and um and uh conan will probably be interested in this but i first met him in 1978
i was just in the process of separating from my practice marriage as i like to call it
and uh peter was in kingston giving a lecture to the local organization
and uh right away at the near the end of his lecture he wrote down his career goals
to become president of the royal astronomical society of canada and we all kind of got a good laugh
about it but i don't think any of us are laughing now because peter went on to become
national president of the royal astronomical society of canada he is still the honorary president of the london
center of the royal astronomical society of canada peter um when it comes to uh observing
together that we've done for so many years to me it's not so much the results that
count it's the process the passion being out with the telescope looking up at the
night sky and so peter and i are going to attempt to sing for you a song that peter wrote
called the battle hymn of the astronomers peter are you ready i am ready david
let's go all right mine eyes have seen the glory of the
whirlpool i have
all day
starry skies [Music]
each night
i feel the vastness of oh boy
[Music]
as the nights grew cold around me and the planets hurtled by
across 10 000 parsecs when i watched the globulars
[Music]
[Music]
global star
[Music]
only on the global star party that's right
you know it's actually it's really kind of sobering to think how much harder it is to sing and david and i love to
sing our songs to sing our songs when there's not a live audience right in front of you you know
it's actually quite i wonder if you know folks who make a living performing in music must
know the difference between you know what it feels like in a studio versus what it feels like to do live
performances and so on it's it's really kind of neat when you think about what's going on in your mind as you try and do
that but anyway it's been great fun it's awesome it's probably the 103rd time david and i
have sung that song together
i thought that was awesome thank you guys thank you make it fun man that's great
okay uh so um we are going to uh uh
we are going to transition to uh the astronomical league uh john goss is here
with us and um the astronomical league is the world's largest federation
of astronomy clubs but they are they're not an exclusive organization in
the way that um that they you know they don't embrace other
organizations this one does uh the astronomical league
i would say is a very inclusive group in fact they're going to be doing an
event here with the royal astronomical society of canada which is the largest uh federation of astronomy clubs
and organizations it's not really a federation of astronomy close because every
unit is part of the rasc but they unite amateur astronomers across uh
canada and a lot of uh united states amateur astronomers also belong to the rsc rasc
because of their incredible programs their outreach the educational work that they do
and all the great astronomers who've come from canada uh uh many who have appeared on this program and uh uh
including david levy who has been on all of our programs so um it's uh it's
great to have uh them on um we just finished about maybe about a
month ago the astronomical league convention in albuquerque and that was an exciting time uh and um
you know we had some great speakers stopped by my booth and we broadcasted some talks from live from the
astronomical league convention uh we had shostak who's the lead astronomer for seti uh
gave a live presentation as well that was a lot of fun so you could see the inner goings-ons at
the astronomical league conferences and um so uh you know really want to thank them
for all the support that they give to our community um and if you don't already belong to
the astronomical league uh whether you're in canada the united states or anywhere in the world you can go to
astroleague.org and become a member so john i'm going to turn it over to you
thanks for coming on to the 103rd global star party oh well um
thank you scott that was a nice intro uh uh plug for the astronomical we'd really
appreciate that you know you did mention about alcon we have that every year people ask themselves or other people
what what why should i go to alcon why should i go to something like that but when you think about it this is an
opportunity for amateur astronomers or stargazers really to meet with others
to learn a little bit more about the hobby to see what other people are up to it's it's their chance to speak with uh
oh people in the field like magazine editors book publishers uh university professors
um astronauts um observatory people you know plus other amateurs of all
expertise levels so it's just a great chance to to do that and expand your horizons to discover more about amateur
astronomy i think that's all i'm going to say about that i could go on for another half hour about attending alcon and
things like that sure but uh anyway scott you started out asking you know what well
what events or what facets of astronomy really affects us all
and i i i think about this now and then and it's it's one thing leading into another
well once one part leading into another part and i'll start out with really you get kind of a
personal introspective feeling when you look up in the stars because
you are confronting mass energy space and time you know all all the fundamental
concepts of our universe you can't help but face it so that kind of blends into when you
look at something and you achieve which i know a lot of people call this the oh wow factor
and that's really something that's really incredible a couple months ago i was at the green bank starquest very
dark night i had a fairly small telescope that night but i was able to see the veil
nebula and i don't mutter it very often but i did say oh wow
there it is you know i kind of incredulous but i thought that was that was pretty good and again here i am faced with the
concepts of mass space time and energy time
eternity you know the whole whole range at all but anyway that's not why i am
here tonight i'm here to talk about um our door prizes that the league gives away
every month um and each global star party uh all y'all have a chance of answering three
questions to be put in the list of winners to be to have their names drawn at the end of the month
or at least at the next uh at the next star party so i want to jump into that now and show you what those questions
are if things go well with me
yes good good thank you uh let's start this this
thing here first of all we like starting out with just a friendly warning about
observing this um um some people love observers some people
have done it quite a bit but we do have newcomers and for the newcomers we just want to make sure that everybody knows how to do this safely when it's done
correctly it's completely safe and you tend to forget that it can be dangerous if you're goofing around and
not doing what you're supposed to be doing so be sure you have the correct solar filters placed on the front end of
your telescope make sure that the telescope is not on it it's not left unattended so other people
inexperienced people who come mess around with it and and maybe knock the filters off or
something but when all this is done correctly it's really a pretty safe safe activity and this is going to be coming
up because we do have some eclipses in the next couple years which are going to be in the in the news a lot of people are going to be looking
at the sun and we want to just want to make sure it's always done correctly
the answer is from last week's quiz we had three questions and uh before i start out i will remind
you that if you are participating this week be sure to send your
excuse me be sure to send your answers to the secretary at astronaut at astroleague.org uh lists your answers
but for for last week let's see let's see what they were um question number one
what are the only two planets in our solar system without moons venus and mars jupiter and saturn or
mercury and venus well hopefully uh we've all passed the fifth grade course in astronomy and
realized it's mercury and venus you know we talk about how hard or how easy these questions could be and i'll remind you
that a question is only hard if you don't know the answer so
we'll see what happens question number two who named messier 11 the wild duck
cluster that's a beautiful star cluster look at and it's greatly it's ideally stitched with this this
time here a chance go out and have a look at it you can see it binoculars through a small and through a small telescope
on letter a admiral smith now i read up do your spouse's name smith or smith
well on the internet it's pretty much divided both ways um of course there's charles messier or
edwin hubba well it's admiral smith question number three
what term is used for the condition when three celestial bodies are arranged in a straight line this is always one of my
favorites because it's such a such a screwy answer i think uh a triplex b
apparition and c syzygy well susachi is it i think that is a cool
name if i ever had a cat or something or an animal like that i think i would name it syzygy
so the correct answers from from this week's uh or actually last week's door price
competition cameron gillis who i don't see on here tonight uh uh daving
bill manley adrian bradley who i don't see on here tonight and ani eunis so thank you for participating in that
now let's get on onto the big questions for this week
again send them to secretary at astrology.org question number one
for all you observers out there for observers in mid-northern latitudes what well-known asterism
is found centered at the zenith when darkness falls in late september late august and early september
said a the great square b the teapot or c the summer triangle
so think about that write them down question number two
what planet i i often ask this one a lot what planet is closest to earth tonight
um these things change all the time is it a mercury b venus c mars
it helps us know uh our place in the solar system and how things are in the night sky
question three which moon is the most massive is it jupiter's ganymede
saturn's titan or pluto shawn well we'll see
so be sure to send your answers in to uh secretary astro league dot org and uh there'll be a drawing um later on
for that before i get out of here i plug our next astronomically live
session which is another three weeks uh on september 16th that's a friday night seven o'clock eastern daylight
time we're having brent maynard uh who will talk about preparing for a night of image capture so if you're into if you
want to begin amateur uh imaging this might be a good place to start we're also going to have a little focus
section uh hosted by molly wasser uh who is the deputy director of this right uh the
international observing the moon knight from nasa uh which she'll be talking about that program i believe
international observe the moon night is october 1st if my memory serves correct so that's a
chance for everyone to get out and look at the moon so anyway thank you for putting up with all this and be sure to send all your
answers in to secretary at astral league.org thank you scott i'll turn it back to you
so here we are um you can see that uh i can see levees
signed on here and we've got uh young navin on as well and um
so anyhow we will get on with the next part and thanks for sharing uh john thanks for
sharing your views on you know what uh impacts you most about astronomy that's that's totally cool
okay so uh up next is professor kareem jaffar he is from uh uh john
abbott university and he is from the royal astronomical society of canada the
montreal center kareem is uh somebody i think just almost completely
utterly devoted to educational outreach and astronomy um he is uh
he does amazing uh events in canada uh where he lives he's very involved with
youth in astronomy uh and he's going with me to do a major star party event
in yerevan armenia uh at an event called starmus and so we're all excited about
that and um but uh i'm going to turn it over to you karine thanks for coming on to our 103rd
global star party oh thanks scott we're really excited i cannot wait for a starmus i'm trying to uh trying to
scramble to get everything ready on my end so that i can just enjoy the experience i watched the
special that you and david eicher and uh i believe michael also yeah michael back
it's also the three of you put together i watched it last night while i was prepping today's class and just got a chance to enjoy seeing
how passionate the three of you are about the the astrophotography week leading up to starmus and then stardust
itself that's just going to be wonderful i can't wait really i've been
thinking about it dreaming about it and uh so it's definitely a bucket list item
for me what i think is great is that starm the organization starmust made it um
affordable for people to go you know and um you know this this year it's in yerevan
armenia i know that sounds like a long ways away but international travel is not as expensive
as what a lot of people think it might be it's a hop skip and a jump yeah that's right
one of the jumps is a long jump but you know that's just because of the water in the middle otherwise otherwise you get there
pretty quickly that's right that's right and no but even just listening to the lineup i mean we've got
you know kip thorne chris hadfield's going to be there for the canadians that are interested in coming over
um rick wakeman uh we've got uh on the board of directors
yeah and and he's with jericho israeli and on the board of directors then you even have peter gabriel and uh and uh
richard dawkins on the board of directors i mean there's just amazing people involved in this festival
and so i really asked you you got charlie duke charles bolden jim beijing chris hadfield's going to be there
garrett reisman these are all astronauts and charlie duke right as artemis is on
its way to the moon it's just such wonderful timing yeah it's awesome knock on wood knock on wood
it hasn't launched yet we're waiting for that on monday um so i'm gonna i'm gonna share i'm
gonna do a small presentation about the theme today new beginnings and uh i will
say complete transparency i just put the presentation together on the fly now
that i have ideas in my head are just fashionable i didn't have time to put anything uh anything down in advance but
it's because there's so much to talk about when it comes to new beginnings and i thought a great place to start is
actually with the land and sky acknowledgement because i just did the two-eyed scene talk for my students today
and i talked to them a little bit about the respect we showed to the first nations the fact that we we share the
sky with them and new beginnings we are just ending one lunar month and about to begin another
the moon this past couple of days has been this waning crescent that's just
barely visible now in the early morning before the sun rises and we are moving from what the settlers
called the sturgeon moon based on the fish that has its genetic code 135 million years old
for that species and now we're moving off to the harvest moon which indicates another element of
appreciation of what the moon does because the harvest moon recognizes the fact that at the autumnal equinox
the moon's rising around the full moon actually only happens about 20 minutes
apart at latitudes close to montreal higher up you go the closer together the
moon's rising is when you're passing that equinox phase and then it'll go back to being 50 minutes apart for every
single phase of the moon rising you know day after day and you go through all the but during the equinox there's this
special geometry that means that the moon rises
early every evening around the full moon which meant for farmers your day was extended
and you could take in all the harvest to prepare for the winter so that appreciation of the new
beginning and then the idea of what moon is coming is something that's implicit
in the first nations you know i talk often about the mikma moons and there's a book coming out now in october from
dave chapman and kathy leblanc from nova scotia the mikma moon that's finishing is very
ripening and the one that's starting is the mating moon and it's kind of cool to see that this appreciation of what's
happening in nature mimicked or echoed in a lot of different cultures because the cree call it the rutting moon based
on the moose scraping the velvet off their antlers as a mating call and so there really is this connection to what
we're seeing in nature and i'm talking about the moon so i have to talk about artemis one because if everything goes
well artemis one is going to launch on monday and that's a new beginning for
not just the us space program but for everyone because it's humanity's return to the moon and the artemis one is an
uncrewed mission just to go by the moon make sure everything's working well and then the artemis ii crude mission won't
land but it will go around the moon and it will include a canadian astronaut in
the contingent on the crew going there and that artemis 3 if everything goes smoothly will indicate
our first steps on the moon since 50 years ago this december
so that is a incredible new beginning for everyone interested in space exploration
we are celebrating it this saturday as part of the family day at the montreal aviation museum which is something that
we do every summer and the reason why i'm pointing this out is twofold first you've got my wife there with all of our
rask material giving it out and answering everyone's questions from last year or actually from the last pre-coveted year
but secondly because the organizer there is a nasa space educator diana phillips
and today all of a sudden diana phillips got the information from a sponsor
that they are sending her for the artemis launch so she's going to be there on monday if everything goes well to
watch the launch in person so i just want to do a shout out to diana because i know how incredibly excited she is but
she tries to catch our global star parties whenever she can so i wanted to point out like this is just an
incredible opportunity for her on monday our space oddities will be talking artemis we're going to hopefully
share a little bit of the live launch and then during our weekly show we're going to be talking about all things
artemis and i'm going to be discussing a little bit about the orbit and the decision for when the window opens for
the artemis crew to or for the artemis mission to actually launch in the sls
system and how it's actually going to operate to go there
before that on sunday we have our next public event and for me this is another
sort of a new beginning because this is the last event co-hosted with the space
club while my son is an executive of it and he's the one presenting it because he got to spend two weeks at mount
wilson as part of the soar program so he's going to be talking about his experience
and we're looking at a new executive for the space club and he himself is starting a completely new beginning at
university of ottawa next week in the honors physics math program so i've
already told him that he has to make friends with connell and make sure that they can chat and share experiences
because connell's right around at the same level as him because coming out of the cejap he goes straight into second year at university when he goes outside
of the province the other way it's a new beginning is as i mentioned this is our first week of
classes here at john abbott and all the way back in gsp 48.
now scott gsb 48 that's like june of last year that was just after i had done the
co-hosting with russell of gsp 45 our big marathon for international astronomy
day and you had asked me can i come back and talk a little bit about what i'm doing at the college with my students and i
gave a whole presentation in gsp48 about the way my students approach
observational astronomy outreach the way in which we connect with the rasc montreal center
and we had our shad event again this year and it was incredible to see a few of the students who didn't have a chance
because of covid to be out in person to have that opportunity but you know talking to my students the
last three days i was worried i was going to be giving them whiplash but yesterday in the clubhouse one of the students joined in
and by the evening he was talking about binoculars and getting advice and a couple of students have already borrowed
telescopes from me for the weekend a bunch of students have stayed back to ask questions about
everything and even during my intro to the night sky i happened to mention
the uh the black hole picture at the center of our galaxy and i gave them the sky news magazine that showcases it
and the students wanted to talk black holes for about three four five minutes and they still had more questions that i
said we're gonna get there we're gonna get there you just gotta hold your horses you gotta build up to it but the excitement and the interest in
learning at the new beginning it just it drives you it keeps you going and tomorrow i have my first meeting with my
honor science cohort because i'm now the honor science coordinator here at the college another new beginning another
new hat to put on but it's one that i'm really excited about because those are students who
really they they're ready for leadership positions they're ready for outreach they're ready for involvement on these
campuses because they're go getters they're performers and they want to know more about how everything connects
together and so i'm looking forward to trying to take a little bit of what i do with astronomy and bring it into the
honor science in a way that encompasses all of steam not just stem but also the art component
so talking about the art component one more new beginning scott mentioned james webb space telescope and even before we
get to the beginning of the universe the cosmic cliffs from the carina nebula
one of the first images released by james webb space telescope has led
to an enhanced understanding and more theoretical work being done on
the new beginning of stars being born because hubble could not look past
the edges of that dust curtain there and when you compare the hubble picture
to the james webb picture the james webb picture not just it's not just that it shows more of the
stars but these cavities these pockets that show as the stars are being born
the space that they're carving out for themselves inside these dust clouds enhances our understanding from what
we've had from examining the orion nebula and other star-forming regions
but what scott was alluding to is something that i did put into my presentation which is when you look at
the deep space images coming from james webb even just that first one that was
that was presented by president biden you compare it to hubble to james webb
and we were all blown away by the number of additional galaxies by the resolution on those galaxies and that resolution on
those galaxies is where this new cosmological conundrum has come from because what we've determined based on
the redshifts and what we see morphologically is that there seem to be a lot more
spiral evolved actually what appear to be well organized
galaxies very close to the dawn of time very close to when the first formation of
materials would have been happening and that doesn't match with what our understanding was of the way in which we
started from the big bang reached the cosmic dawn and then started to have structure forming in the universe
so the very beginning of time itself is currently under consideration
and so our theories and our understanding over the next few years is going to constantly be challenged and so
we have to be open to a new interpretation of those beginnings that matches with the actual evidence that we
see and with that i'm going to put in a caveat that it's important to recognize that
any redshift measurements have to go with distance in order for you to determine
whether or not it's a reliable measure of what you're seeing for these galaxies so
the redshift measurements themselves have to be as precise and as accurate as possible and you need more than one
measurement in science to say that this is a verified observation so as much as i'd love to jump in front
of the train and say yes yes all of cosmology is wrong let's rethink everything we can't that's not responsible science
responsible science is to say we have evidence now that throws question
on our understanding of the way in which matter formed and galaxies evolved and formed structure
and now we need to design what our next observations what our next experiments even what our next telescope
is going to be in order to further delve into this particular question
so with that i'm going to again mention said
my new beginning my new challenge my new experience i have not flown anywhere in many many
years because of my own medical condition i was very afraid to and i'm taking on the challenge and i'm
really excited about going to starmist going to armenia being part of this incredible festival and especially on
the thursday night getting up on the mountaintop in garni with scott's
crew of telescopes whatever he brings us and even if there's no telescopes i'm just going to sit there pointing out
stars and pointing out constellations pointing out asterisms telling stories and listening to the stories of the
people of armenia and the guests that come from around the world because this is an opportunity not just to share what
you know but to learn from others as well so with that from the rac montreal center
thank you very much scott back to you fantastic presentation as always
that's great okay well um everyone we are bringing back uh
uh libby in the star she's been gone for a while she did go to the
to the nebraska star party and she's doing what any young lady should be doing at this time
and that is enjoying her life at school and she's right now at a football field uh
uh you know uh beaming in live uh from from her other activities here
libby thanks for coming on to global star party hello
um i'm on my phone right now so bear with me um i do have a presentation so
let me see if i can get to present
um how do i present on the phone okay i'm just gonna kind of share with
you um the stuff um on this slide even though i can't share this slide um so while i was
at the nsb this year um i got to meet some amazing speakers and one of them that i got to meet talked a lot about
quasars um and i was kind of interested about quasars because i was like you know i've
never heard about this before so um i wanted to kind of do a little
presentation on quasars um so first of all i want to cover what our
quasars so quasars um astronomers first began to notice them
in the late 1950s and early 60s but quasars aren't stars they're actually young galaxies they're very distant from
our planet earth but they're but how are they so far away and we can still see them well quasars are very
bright they're even brighter than our own galaxy these playgrounds are highly active and that's why they are so bright
so basically quasars they're really bright objects that astronomers started to notice and we thought they would
actually be very close to our planet earth but apparently they're not they're actually really active young galaxies
they can be even up to 100 times brighter than our own galaxy
one thing i've heard um about quasars being centered galaxies so
with recent studies astronomers are now believing that quasars are the centers of galaxies after more
research we have another term for quasars active galactic nucleus aging is
simplified basically this means it's the center of a forming galaxy because they give off so much radiation powers a super map
so they can power a super massive black hole as a matter in a quasar
as matter and replace our a creationist heats up and it generates
radio waves x-rays ultraviolet and visible white this makes quasars visible and this is
why they're so visible to us even though they're so far away um i have a picture here but i can't
share it with you but it's um it's a model of an active galactic that can
apply and the um and it's kind of like a model of like
the building of it but i wanted to show you guys that i can't but um it's the accretion that's that
heats up that makes it so visible from our planet the quasar becomes so bright that's able
to outshine galaxies so um
another like type i wanted to talk about a type of agn so these are called safer
galaxies on the other hand there are galaxies that are not classified as quasars but still at the bright active
centers where we can see the rest of the galaxy an example of this type of aegean is a saber galaxy
uh messier 77 if you guys have ever seen that um it's
pictured on the slideshow but i can't show you guys that is pictured though um over on the other side if you guys
have ever seen it it is a classified sacred galaxy um the safer galaxies actually make up ten percent of the
galaxies in the universe however they're not classified as plane drivers because they're much younger galaxies
and usually the safer galaxies have more like construction to them and you can
kind of see them better but the um and the younger but the um
typical ones they're a little bit more loose um
so actually recently i just got back from the nebraska star party and it's been a
while so i want to come on here and talk about it but um
i had an amazing time at the star party this year um it was great to meet a bunch of
different people because i'm so used to coming on the virtual star party and be like oh you're
muted but here i was like oh it's an actual audience
so i was so glad that i got to experience presenting in real life because a lot of time
times it was weird because i know i do have a lot of viewers on
here but it's weird being in real life i get to see how many people that actually is
yes and i actually got to speak with a bunch of other different speakers and i
love getting to meet a bunch of different people um a lot of great memories were made
um i actually wanted door prize while i was there for a telescope and i remember like actually crying when
they said my name because i was like oh my gosh and i was waddling back that is awesome
i heard i heard libby i heard you gave a terrific talk at nebraska's star party so you
must have been really uh energized by the whole experience i think that's great
oh thank you whoever said that thank you um it was it was kind of
it was kind of stressful at the same time because like every single night we were staying up late to like three
like out at the park and then like three at the earliest and then we would like sleep in the car a little bit then go
back to the hotel because we didn't bring a tent so i would like show up i would like show up
with the presentation and be like oh i'm probably gonna be super tired i'll probably just be like you know what let's do this you know let's do this
but i got there and i was like super nervous i was like oh my gosh this is more people than i thought
um i got to meet a bunch of people my age who were interested in astronomy
um i know i made a couple friends there and um i would like to thank kent from
export scientific for helping me a lot during this um during the star party i
forgot to bring a lot of things and luckily kent was there to help me um well it's good
yeah there was a couple storms that moved in and out and i really loved watching it and watching the lightning
and it was super pretty to be out there and i mean it's just like there's no better feeling than being out on the
road and like it being completely open it was absolutely like beautiful out
there with all the sand hills i'm already i'm very happy on the calendar for next year i want to go back
and um i want to stay on campus of the star party so that way it was a
30 minute drive um back and forth from the hotel to the nebraska star party
right um i really liked i think i would like it better if i
stayed on property and everything but it was beautiful even the drive back and getting to see all the pretty stars and
like i mean you could like the first night that i got there it was
storming but like the next night when i got out there and i saw the stars once it started getting dark i was like oh
wow this is super pretty and then it just got better and better by the minute because it just kept on getting darker
my eyes were adjusting and i mean everybody was super friendly at
the star party um i didn't my job sony and telescope since it's such a big
telescope um i had to carry it up to the hotel room every night
like on the little thing i would like put it in the bucky and like bring up the mirror box and everything and
the hotel people be like what is that like it's a telescope but um a lot of people were really nice
um and even some of my telescope um telescopes since i was setting them up like one night i
didn't really have time to i mean i had time but it was kind of difficult to set up an observed so i went down job row at the
nebraska star party and like everybody was super nice and they're like hey we're looking at
messier 50 something and i'll be like oh my gosh it's so cool and they'd be like yeah so this is actually this and
everybody was super nice and caring and it was just so fun to be at like
seeing how many people there really are who join and
it was just weird being out there too because where i live in bensonville there's so many walmarts that like every
corner that you turn there's a walmart but there wasn't a walmart for a good five hours where i was at
so it was just it was just super fun being out there and i really
enjoyed it i got to meet a bunch of new people um my
um speech on quasars is actually inspired by one of the speakers who um
spoke at the star party named diana who spoke about quasars and her um
research on quasars so i thought it would be a good idea to kind of come on here and talk about it
because i was kind of interested after she started talking about it and her research and everything
that's great that's great so um did you libby did you think that um the nebraska
star party was kind of like a good event for a whole family to come to or
do you think it's just amateur astronomers or how do you feel about the event itself
so actually at the i went to the nebraska star party board meeting um
the last couple of days and i suggested that they have an amateur row for amateurs
to come and set up and maybe yeah and i would definitely say it was a family
event because i saw lots of little um little kids there who came up to me
and were saying hi and i was like and a lot of them said that their parents brought them there and that they
were enjoying it and even they had kids store prizes which i was into the kids store prizes and
i saw lots of kids at beginner field school and i definitely think it's definitely a family event because you can come out
there and camp and i mean it's just absolutely beautiful i mean the sand hills and like
the sand hills and all like the like amazing like nature that's out there i
would definitely say it's something that like a whole family could come to because
even if you don't have a telescope or you're not sure or you didn't bring yours or you only
brought a pair of binoculars everybody is always willing to share their view of you
yeah and they're always helpful and even just going for beginner field
school i went to beginner field school every day and i got to learn some amazing things that um
you know i like yeah it was just amazing that's cool that's cool now nebraska's star
party is also known for its super dark skies it's probably the darkest skies you've ever been to i would imagine right yes
it was how would you describe it um well i
the first couple nights it was stormy so i was pretty upset by that but if i had
to describe it in one word i would say like pitch black it was
and then the stars you could see your shadow from the milky way and it was
it was everybody took the red light thing serious i got i had some red
lights they used and we were really cautious about making sure that the car lights didn't come on yeah and
everything and everybody was really good about that and i mean really valentine nebraska there's
not a lot of things out there like people so i mean they were talking about it and
the less population they're like the less population the less light that's true
i know they were even talking about as meeting um at the board meeting that we finally got
the darkest ink skies and i would definitely describe it as that because i mean
even at my house the sky is black but you won't see stars but when i went out
there the sky was black and you could see the whole milky way across the sky
and um i downloaded i downloaded nightcap on my mom's phone because she has a really nice phone camera
and um even without nightcap and with nightcap just putting your phone up to the sky
and taking a picture she captured multiple stars galaxies and
constellations so amazing it's amazing that's great well libby thanks for taking your time
out uh to be with us on this global star party we hope to have you back soon
in this remote setting in this remote setting that's right
that's right it's beautiful that's great thank you for having me on
thanks so much okay well we are going to um we are going to
go to young navin uh santel kumar
who is uh giving his next presentation i uh naveen i did not get your present the
name of your presentation but um but uh present perhaps you can present
it now but i i want to ask you uh uh the same question that um
that i was asking other people here tonight out of all the things that you
have experienced about astronomy and the universe what is the one thing that really just
blows your mind i'm just
the most thing i'm curious about right now is the big bang theory i still plan i still plan to learn more
about it and um hopefully i i gather more knowledge about in the coming years and i um and i
hopefully i i get an answer for it i think you'll be one of the guys that'll be studying hard to figure it
out that's great that's great and what's what is your presentation tonight
today my presentation is going to be on exoplanets because i thought the theme would be is about finding was about life
and like new new beginnings and things like that so yes
relevant to that so yeah great okay but you get the stage so let me share my screen
you see my screen uh it's coming up
[Music] yep how to find exoplanets there you go
exoplanets by naveen santo kumar so
let's firstly talk about what we know about exo planets we know that nasa and esa and amateur astronomers have find
about 5 000 exoplanets we know maybe more but they're still finding them every day
so many pla many planets they've found traces of life
they have they haven't really we don't know if there's life but there's a lot of earth like planets like earth with all the
earth resources and that may sustain like life but the good thing in the future we
might be able with a new set newer new and newer satellites and space technology and telescopes and all that
crazy stuff coming we might be able to find find and gather more knowledge about um exoplanets
and now i'm gonna and um i'm i'm gonna we're gonna talk about
methods to find exoplanets technically so i have six ways to that you amateur astronomers can start
finding exoplanets alright so let's talk about it first thing is radial velocity
it's basically watching for wobble like a planet like so
it's basically for on the fact like the star doesn't really remain completely like
stationary or like it doesn't stay still necessarily
while it orbits in we can find it by its orbit technically so it's like by figuring out the gravity
um because gravity pulls on everything and stars can pull planets and plants
technically pull stars so like for example like we're like on earth like technically earth
and like the eight planets in our solar system are technically like pulled by the sun's gravity right now
or else if we weren't in within the sun's gravity and like the sun's radius we'd all be just
way out in the middle of lower floating i guess like stars maybe instead yes so
yeah that's radial velocity let's talk about the good things and the bad things it's great for finding big
exoplanets in close orbits it's great for measuring how big an exoplanet is and it uses ground-based
telescopes and amateurs can do this pretty easily not so good for finding exoplanets in
this in orbits not so good for measuring diameters for exoplanets
and it's not so good for finding little teeny tiny exoplanets like our earth and
stuff all right so let's go to go to the second method let's transit
or the transit photometry method it's basically about orbits so as a
planet orb orbits around the star they technically light blocks star
technically which is the planet which makes the planet easily visible to our telescopes technically so
it's it's um the light that comes to our the from the star like the planet that comes to us so we get to know it's there
all right now it's it's so this is this is a pretty easy method it's like the am it's like an amateur method so it's it's
a direct imaging or as we know directly taking pictures as you see we point a telescope from an
observatory up and we take a picture of a couple stars and we directly just see
exoplanets we zoom in and if you see it's basically using infrared which is which ends up
like this so you get to decide like you could see like hot spots and like all sorts of
fancy stuff like that which you could see and you end up with images like this planet b planet c
planet d that kind of stuff so now let's talk about method number four microlensing
did you know gravity can basically bend light it's it's true so
when when a star passes through in front of another it bends
technically the light like a lens making it magnifies it making it brighter
if the lens making star has a planet it makes the star even brighter so it
magnifies the star so you technically have the star right here the lens which is the exoplanet and you
get to view it from earth so yeah let's talk about method number five
astrometry stars and exoplanets can get pulled together and it gets crazy and all that
stuff so they they pull any and they get started on unexpected paths when
then we notice a star moving irregularly in comparison to other nearby stars so
that's that's going to signal us with an exoplanet so that's let's go to number six timing
variations it's basically like tug of war like a game of tug war where you have to pull
on one side and pull on the other it's basically when the star firstly starts pulling on us
on like a planet and then it pulls and attracts another exoplanet and that tug
of war makes gets some sort of unusual path pattern or algorithm
which telescopes can read and we know it's it signals like um
in in exoplanets there in that specific area all right that's all that's all
for my presentation thank you that was a pretty short quick presentation and hopefully it was
helpful and hopefully you can start finding exoplanets on your own with my information
scott you're in me by the way myself how about that is that better
oh yeah you know no it's a very good presentation having on
exoplanets and the way that they're studied um we have uh we're associated with an
organization called the mark slade remote observatory and they use a six and a half inch uh
refractor uh to do to detect exoplanets and so um
you know the thing that's amazing i think is that you can use fairly modest equipment
but careful uh recording techniques and do follow-on observations with the test
team uh and you can make observations of exoplanets especially like eclipsing
ones okay where you can watch a light curve there is a
there is a something called a diffuser and diffusers cost
two or three hundred dollars okay but they fit in like a filter okay and this
goes right in front of the lens and that diffuser looks like ground glass but in reality it's a bunch of tiny little
lenses and what it does is it takes the light spreads it out over all these tiny
little lenses and then instead of the starlight falling on just a few pixels
of your sensor it now falls on hundreds or thousands of pixels
and what that does is it gives you a better signal to noise ratio it allows you to
eliminate some problems like periodic error in your mount
you know little drivers scintillation problems that can mess with your photometric data and uh
so um with a very modest uh investment you can be making real high
precision uh photometric studies um so if you're ever interested in that
uh gavin or anybody anyone else that's uh listening get in touch with me and i
will hook you up uh so that you can find out more about this diffuser and you can start doing the
diffuser photometric method so it doesn't take a lot of fancy equipment uh the
i think that most of the software is free and uh but the diffuser is really a
remarkable uh advancement pretty much pretty much finding exoplanets is a
pretty much any amateur astronomer can do so that's why i wanted to share this and be pretty useful for everyone isn't
that amazing yeah i mean that would have been something uh years ago that would have probably only
been left for the professionals to do so it's great that we can do it too yeah awesome
all right uh so up next naveen thank you very much again and uh hope to have you
back on global star party real soon um thank you again
uh our next speaker is uh author and space artist uh michael carroll and
michael um his uh presentation is deep time and
exoplanets so um we are getting a nice uh double dose
of exoplanet presentations here i love it and uh mike cole thank you so much for
coming on again on global star party well it's great to be here thanks so
much um naveen did a great job and um so
i will be able to skip a bunch of my spots
anything to make it easier yes yes right so i'll uh cut to the chase the main
part of what i'm going to be talking about uh tonight is um some views of some of my favorite
exoplanets that we've discovered but before that uh let me go into screen sharing here
and let's see if this will work
there we go can you all see that yes
okay excellent so here we are new beginnings um
first i want to talk a little bit about deep time you know we've all talked about uh how telescopes are
like time machines and we we can look through them and we'll see the way
the the andromeda galaxy was 2.5 million years ago i think that's the
distance but i was thinking about um
what would happen if somebody else was looking through a telescope from the other end
that gives us a different perspective on deep time yes telescopes are like time
machines and if you had one in andromeda it would be like a time machine looking
back on the earth itself light is moving away from the earth like uh
like the uh waves in a pond when you drop a little
pebble in so what happens if there's some somebody with a maybe a little bit different
architecture looking back our direction seeing light from the earth today what
would they see as you know we look at the sun and we're seeing the sun as it was about eight
minutes ago the it takes that long for light to travel
we can do the same thing by looking at some of these other nearby and not so close
objects so let's have a look here i need to rearrange my
screen so i can see hi um michael is is this is this an
illustration that you did yesterday solar system it's fantastic
thanks so much well it's fun to think about things in in these terms kepler 22
for example is a a somewhat sun-like star i think it's a k-star a little bit smaller and cooler
600 light years away um if somebody was sitting out there today
what would they see looking back at the earth
my screen is not moving oh there we go um kepler 22 is an
interesting system uh it does have a super earth apparently right in the
habitable zone uh in the inside edge so it's probably a little toasty but it's
big enough that it may well be a water world and if you had somebody out there
with a telescope floating on the surface of that ocean today they would be seeing the
renaissance on the earth they would be able to see if they had a really good telescope
they'd be able to see leonardo painting the mona lisa that's cool
if we move out just a little bit more to the orion nebula and look back at the earth today again
light waves from the caliphate of cordoba are just reaching
the trapezium right now but go a little further to the great
blue giant denim beautiful blue star uh it
people in orbit around deneb will be seeing the roman empire of constantine that light
is reaching deneb today this moment let's go on a little further what about
uh 5 000 light year away the garnet star
cpi is that the way you say it cpi it sounds about right
okay i've seen it written but i haven't heard it anyway uh out there
we would be the the light from ancient babylon ancient egypt the minuen empire
that light is reaching the garnet star today as we speak moving out further the large magellanic
cloud we see the end of the neanderthals our beautiful
kind of almost twin galaxy sister galaxy andromeda is looking back at the
beginning of the ice ages and the first great uh
fauna of the ice ages we'll see way out there at 10.
4 million light years i think that is so just a little bit different way of
looking at the telescope as a time machine and and noticing that light
and the way light travels really does help us to uh to envision traveling
through time so let me [Music]
here we go nice effect
so it's uh you know we're we're familiar with this somewhere out there there may
be somebody on an earth-like planet looking back at us and saying
what were they thinking so new beginnings in our search for other
worlds there have been quite a few it's been an exciting time ever since uh
the kepler observatory got going we've had some breakthroughs in
our search for earth like and other exoplanets
naveen did a great job of covering some of these techniques that we use to
find other planets transits of course are what kepler uses
are used in its uh spectacular mission uh just watching the
the light levels of the star drop as a planet goes by and as he mentioned you
can see all kinds of things about a planet when it does that
um these diagrams get very complex when there are multiple stars then of course
we've got the uh uh the microlensing method where you see a
brightening of an object because of the warping of gravity but it brightens up twice if it's got a big
planet alongside of it so this is a another technique that has has
really come to the fore recently it's it's uh matured didn't used to work too
well uh but it does now and now uh here we are with radial velocity looking at a
normal star here it is sitting just plopping out to a little nice yellow light but then oh wait something
mysterious happens yes that light changes it shifts in color
goes uh toward the red and then it goes back to normal what could be happening but then wait it
gets blue it's because that star is wobbling back and forth toward and away
from us and because of the way it does that we can time it and see
um how massive the unseen planet is that is tugging away
on that star and by the way um even our own sun gets yanked around quite a bit
by jupiter primarily a little bit by saturn but um if you look at the way our sun
has moved if you set back around 30 light years or so this is what you would see
this is how much our sun moved in the sky wow it's pretty
yeah it's pretty amazing so what did we find with all those
initial things the first 3 500 or so planets that we discovered with the kepler space
telescope alone this doesn't even count all those other techniques but uh larger than jupiter planets there
were about 102 out of 3 500 that's not a lot
jupiter size planets 229 that's more but what's surprising is how
many neptune-sized planets by far the majority of things we have found out
there are about the size of an ice giant in our solar system
some of this uh is within the data it's skewed a little bit because you can find
bigger planets much more easily uh but nevertheless we are getting an interesting curve
super earths earth uh planets between the size of earth and neptune
um come in second to close second a thousand of them over a thousand
uh in those three thousand so a third of the planets that we've been finding are
super earths earth sized planets come in at 674. so
if you combine those two you find that planets about the size of the earth
that may have some similar conditions depending on their their orbits um
they're the majority um so let's talk about a few of them the
habitable zone is is a very very important uh part of the equation if you're
looking for um an exoplanet that is earth-like we uh
arguably have three planets in our habitable zone venus is probably not
quite in it it's uh close to the sun mars may well be in the habitable zone
if it had more atmosphere it would be quite a different place earth is
smack dab in the middle and again the habitable zone is the area around a star
where you can have liquid water on the surface of a world
there are habitable zones different for each star unique for each star
and if the star is bigger and hotter that habitable zone will be a little bit
further away if the star is a red dwarf a nice cool thing that habitable zone
will be very very close probably equivalent to the inside of mercury and in most cases
so um looking at kepler 62 there's some interesting things going on up there uh
62 f and e are both well within the habitable zone of this little red dwarf
there are several other planets that are pretty close to earth size but very very close to the sun so
they'll be really hot worlds but let's take a look at what we might see at kepler 62 e
and f oh by the way if you want to see some nice images of
planets envisioning exoplanets i did for smithsonian and what i like about this
book is it it shows off the work of my colleagues it has lots and lots of space art by very
very talented people so um if you want to pick one up you can
browse through some of these uh beautiful views of of exoplanets and science has gotten to the point where we
have enough data that we can make a pretty accurate guess hopefully uh as to
what conditions are like now kepler-62e is on the inside edge of that habitable
zone it is likely a super earth so it's uh big enough that it's going to
be covered in a global ocean it's also big enough that it's probably got multiple moons but
it is tidally locked to its red dwarf star it's close enough that it's going to
keep one face toward that star at all times then the next step out of course is
kepler 62f and it's also a water world but it's
probably below the freezing point so although it has a global ocean like its
sister world that ocean is going to look very different it's going to be a lot quieter
here we are at kepler 432 i think all the little
uh boxes are in in the way of my screen here but um this is
one of the earth-sized planets that are orbiting in the habitable zone of a red
dwarf but there's a problem with red dwarfs they're very cool so you have to be
really close to them to have liquid water and we call red dwarfs flare stars
because every once in a while they blob out big chunks of radioactive material like this one is
you can see the tongue of a flare to the lower right and that's not very
good it gives you a uh an area that's a lot like a surgical
unit nice and sterile um there are some things that might
enable these worlds to have life for example if you get a strong magnetic field if you have a big molten core
you will have a natural shield for some of this radiation
also again these worlds are mostly tidally locked which means that you're going to have an entire hemisphere
that doesn't get all of the radiation that the sunlit side does and you can
imagine something along the terminator where you would have the best of both worlds
this is another one of those tidally locked planets uh there are many of
these we call them eyeball planets because they keep one face toward the sun
which means that uh it's hottest right at the sub solar point in the case of an ocean world a super earth
you'll have a global ocean that begins to freeze as you reach the terminator
the line between day and night but the sub solar point that points right at the sun is going to
be nice and toasty and maybe even boiling in some cases
here's another one a more terrestrial version of an eyeball world where you
would get desert conditions uh way over toward the uh side that faces the star but along
the terminator you'll get liquid water and in jungles and shopping malls so
of course nearby we have found proxima centauri b this is
very exciting proxima is uh is a red dwarf you can't see it with your
eyeballs uh 90 of the stars in the sky are invisible to us without a telescope
they're all red dwarfs you know in a lot of the science textbooks they talk about how the sun is
an average star well it's not really true the sun is bigger than average
at the average star stars are these cool small red things uh very very ancient some of
them and it turns out that at proxima which is a mere 4.2 light years away
there is a probably a super earth we're not quite sure of how big it is we're
not quite sure how close it is to the star and what that does is it gives us a
range of possibilities proxima may be an ocean world a
super earth uh something like this uh on the left but it may also be even
bigger something a little closer to a uh subneptune
world here we are looking at it from an earth-like moon uh it may have a whole
lot of uh atmosphere and be too close to the sun for
its habitable zone so that would give you a more venus-like world or it may just be like home sweet
home and wouldn't that be wonderful because um we have technology today that
is on the verge of the capability of getting to proxima in 50
or so years so people are envisioning flotillas of micro uh micro spacecraft
writing laser beams out to proxima to show us which of these versions
uh we really have out there there are some weird weird planets out
there folks i love this one uh this one is so close to its star
that it's falling apart uh the solar wind is tearing it to pieces and we can
tell because we've only seen this in the transit method but the the thing is dragging a tail of
debris behind it and so we think that it's uh just just uh it's just a mess
not a good place for a picnic it's way too close to that uh that star of of
it's so uh let's see a strange case of trappist-1
my current favorite system is the trappist-1 system because it has seven
countim seven planets that are roughly the size of the earth they all orbit super close to each other
so you would have tons of eclipses you would have tons of uh planetary
conjunctions the the night sky at trappist 1 would be absolutely
spectacular let's take a look at a couple of the the worlds out there um
earth size not necessarily earth-like okay so we'll keep that in mind uh some
of them here's here's uh one of them the closest one trappist-1b
is probably molten it's very very close even though the star is uh is a nice
cool red dwarf i think it's fairly big for red dwarf um
you probably have a stormy stormy toxic sky with uh
oceans of magma this is trappist 1b
well let's move out a step or two uh and
then we'd be able we're getting far enough away that we can have liquid water on the surface and
conditions that may be quite earth-like at least a thin atmosphere as opposed to a kind of venusian or a jovian thing
these are rocky worlds but as we move out they're becoming more and more icy
um a lot of times we'll view these images by uh from a viewpoint of looking toward
the star but what if you turned around i thought it would be fun to look away
from it here are three the three next outer planets uh all roughly earth
size um to give you an idea of scale the one on the left
appears about the size of a full moon in our sky okay so so you would see this
view periodically it would be spectacular
there we go and then finally if we move way out to the edge of the system we'll be able to
see it in all its glory all of those planets trembling back and forth
eclipsing the star it would be pretty chilly out here uh
probably frozen carbon dioxide and methane and such but uh but still an
earth-sized planet so a fun place to uh to tromp around
so there is the amazing trappist-1 system
and i really think the telosians are out there somewhere we're just waiting to
find the right exoplanet to find them of course they do have a nasty edge to them
if you watch the menagerie but um but at any rate somewhere out there
there may well be life and who knows how intelligent it is we're still looking
for intelligent life here but i think there may be some out there somewhere
so there you are you fun ex planets
all right i love the illustrations michael that was great you know oh thanks
um can you take over my screen and get rid of this
there we go i've lost there we go thank you i i lost my little mouse right
so michael of course you're a working artist uh are you do you produce new work all the time or
is that do you go um i do i i'm doing a lot of writing these days
too i'm working on a new book for springer but uh i get to
illustrate my work sometimes and that's fun too i can write
write stuff that inspires me visually as well and then hit it from both angles so
uh so that's kind of fun wonderful wonderful i look forward to seeing more that's great all right
thanks okay all right um so we will um we will take
a 10 minute break and we'll be back with a more global star
party stay tuned
you're still there peter [Music] i am david and so are you
yeah how many how many more songs does peter and david have actually probably
none right now there are a lot of songs but um
for a while i'm going to go back to the readings and uh but then every now and then we
learn i love the songs i think it's great
yeah that's a good question how many we actually have because there were there were only really three or four
that we really enjoyed doing and did often yeah we've done those two those are we've
done two already yeah so we used to sing take me out to the ball
game in gregorian chant at star parties you know something like take me out to the ball
game you know so then you can add the gregorian chant
you know style to almost any song that you might have
and it drives people kind of uh it's sort of irritating which makes a lot more fun
you know so especially it's two or three o'clock in the morning and you're out at the star
party field and um you know but i'd like to take the words to one of your songs and apply the
gregorian chant uh tune to it so that might be fun to try
um peter i've written to scotty ian i've asked him to add your name to the regular list
thank you i hope i got your address right and uh yeah i'd love to have you on as often as
you can come on peter that would be great sure
uh michael carroll says hey scott caroline and i have an art show this weekend so i gotta go pack our cars
thanks for so much for giving me some time to join and always a blast thank you michael
that's great and dr bradley has appeared
and i fresh off of a loss didn't do so well
but now i get to forget about all of that and worry more about the global star party
which is a lot more fun than losing in baseball how bad it is
but is it more fun than winning in baseball yeah it can be on par with winning in
baseball that's a good it can get close that's a compliment
it's uh yeah we didn't hit very well today and we uh and it's cloudy so i couldn't do any uh
outreach while i was um you know while we were playing i i catch often and a lot of times i'll
talk to the batters and i'll tell them you see that star over there that's capella and you know try and you know
get him worried about the stars then we can strike him out yeah well that's great
um do you enjoy the movie field of dreams i've seen that i would love
one of my um pictures i want to take is to go to iowa
at night and capture the grandstand or the field
of the field of dreams with the stars over it i think it would look awesome i think so too i've been there
that's a that is an image i would love to capture
so but i'll settle for i'll settle for a lake i'm hoping friday
the conditions look promising to capture the cygnus region
setting to the west and um capture both a river which sits next to
saginaw bay here in michigan and i think there will be a beautiful there's a
beautiful image to be had with the river the the bay
and the in the cygnus region setting out over that bay um that's that's going to be the plan i
have to walk through a quarter mile of uh a wooded trail
but if i'm successful out on the other side will be this wide open expanse
of a uh beach a uh river that runs alongside
the uh saginaw bay it'll be a beautiful scene
so i look forward to seeing those results are you familiar with the work of freeman patterson
i am not i will have to look it up okay freeman patterson has an adrian bradley
heart okay and you know his pictures
yeah i will uh i'll see if it looks like he and i are inspired the same way different imagers
are inspired in different ways when we take our pictures i do a lot of uh
i have a success story i have i took a night picture of one of the lighthouses that i love to go
to and one of the keepers of the lighthouse saw the picture instantly handed me fifty dollars and
said this isn't going in our gift shop this is going in my house and i was very flattered
that uh he thought so much of the picture he just wanted to buy it outright and
put it in his house so i yeah i flipped it into a different
image of the lighthouse with the milky way going by it and i took a few more
and um the nice thing about it is i was able to
uh he showed me how to turn off the big lights around the lighthouse it never turns off the lighthouse itself we want
the boats to still be safe but um he uh showed me how to
[Music] do that and it just made for such a fun experience taking pictures around the lighthouse
without the big bright lights present so it's sleepless nights but very much worth it
to be back out there under the stars oh yeah freeman patterson was born in 1937 and
he still lives and still is working but uh
he has an adrian bradley heart i believe i for the
yeah see i think there's a difference when you know when you can look at the night sky
like you um the v and know
almost every every major star in some minor ones and you know what the sky is going to do
and where it's going to go i think it just helps you to um
really capture it you know there's so much that you can do
and all i'm trying to do is bring the sky down for others to enjoy and show
show why we love the night sky so much i i try not to do it you know because it's a pretty picture
and it can be a pretty picture but the beauty of the night itself is what
caused me to try and capture it and um so wonderful to hear you say that
yeah it's yeah i'd like to encourage you and the others on the show tonight
to come to the arizona star party next month i would love to come i want to come you
know why i'm gonna miss going to it is because i have one of my
buddies and we're going to end up about two hours away from you david
in oklahoma while we're getting rained out you all
will have beautiful skies and i'll have to tune in to see
the presentations and i'm going to look at my buddy and say see we should be over with david
over in arizona how about you and your buddy kind of as you're driving along kidnap him and take him dollars instead
there you go he'll he'll be upset and so will our wives but i'll tell him it's
for a good reason because the sky will be the same
um it'll be the same beautiful sky and it'll be among friends so don't worry
uh when when he comes to and he's in arizona i'll tell him what's happening but no i would love to come
to that in fact i need to plan i need to make plans so that
because i would like to [Music] like for all of us to meet in person
while we have the time to meet and enjoy the stars together so that is uh
yeah definitely enjoying the night sky and uh you know i'm sure we're all probably
going to be getting boosters to take here um within the next couple of months i think
that's usually the case but um but we'll be we'll be ready
excuse me guys i'm gonna i'm gonna cut out it's been a long evening so far it's been great thanks for having me and was
a lot great fun thank you good to meet you peter yeah
nice to meet you adrian we'll talk again
all right and as customary i'm going to start my
um drive because i'm going to be presenting
i'm the anchor so i'll be watching and listening in
the sun the source of energy for life on earth
stored in fossil fuels the sun's energy has powered modern civilization for over 200 years but the use of fossil fuels
has resulted in dangerous global warming and a changing climate to the extent that the united nations and the european
union have declared a climate emergency transitioning to clean energy is an
urgent imperative and europe is committed to achieving net zero emissions by the year 2050
but this will be extremely difficult if we rely only on existing renewable and low carbon energy solutions as
intermittency of supply pressures on land use scalability and toxic waste limit how quickly and effectively
existing energy sources can be rolled out
the european space agency has been investigating a new solution that could overcome all these problems
solar power delivered wirelessly from space to earth
europe has the technology lead in building and launching communication satellites this deep know-how can be
built upon to develop and scale up solar power satellites
huge orbiting solar farms built up of many similar parts that will be mass-produced launched into space on
low-cost reusable launchers and assembled together in orbit using advanced robotic techniques
once completed these satellites will collect the full power of the sun's energy 24 hours a day seven days a week
and beam it wirelessly down to earth to receiver stations which will turn it back into electricity and deliver it to
the grid space-based solar power is thus a
continuously available inexhaustible sustainable and scalable source of energy that could help europe meet its
climate and energy security goals this is not science fiction the
fundamental technologies are understood and are already being demonstrated on earth and in space today
[Music] however there are still many engineering and policy challenges that would need to
be overcome to make this ultimate energy source a reality as early as the next decade
other nations are already working on realizing space-based solar power
if europe also wants to benefit from this game-changing capability accelerated investments in research and
development would need to start now to determine if space-based solar power can indeed offer another source of
affordable and abundant energy for our green future and in doing so launch a new european
space energy industry that would provide enormous opportunities for innovation and economic growth in space and on
earth
[Music]
[Music]
[Music] well hello everybody this is scott
roberts uh back from our little break here uh it's a very interesting video
there and um but it does show how innovative and ingenious uh the human
species can be when it's really challenged to take on
you know the really tough stuff to answer uh you know the needs of of a growing
population and um uh you know to create a you know a bright future for
everyone so um coming up next for us we're doing a
little schedule change um uh we have connell richards
who's giving a presentation i have
he his presentation is about dark desert skies that's right i love dark desert skies i
do i think many of us do yeah thanks for coming on con of course
thank you for having me on it's it's been some time uh the last i saw uh some of the gsp crew would have been
around alcon which i was happy to attend uh back at the end of july um a couple
weeks back certainly had a great nice to meet you in person you know what's that i said it
was nice to meet you in person oh a pleasure pleasure it was great meeting you as well i met scott many of the league officers
john briggs many of the the gsp speakers that we
have seen over the past couple of years and it was truly a pleasure to see everybody in person and and get caught
up and during that trip i had the opportunity to do a little bit of astrophotography um out at the
albuquerque astronomical society's dark sky site and i have some pictures for you tonight coming from that one of
which is my background right now a picture of the milky way over one of their observatories
now uh before i begin how is my uh audio and picture is that all okay it's all good it's wonderful
i'll share screen here and bring up my presentation
is that presenting okay very perfect wonderful on the title slide here uh is a picture
i just took with my phone out the back of the van um on the way to
uh the albuquerque astronomical society site it's called general nathan twining observatory
uh that's their main club dark sky site um
somewhere in the realm of of portal one or two i think if you look at the sky quality there
um it's it's 21.7.8 something like that it's it's pristine almost
um with the kind of skies they have out there because of not only the the lack of light pollution but also the wonderful elevation they have there
about five thousand feet um and they're they're quite far out as well and as you can see here in in the
area there really isn't much around in the way of obstructions or things to block targets which made for a great
night of observing now i was there for two nights the first of which was wonderfully clear it had
been raining quite a lot that day because of the monsoon but that kind of settled down in the evening and we found
ourselves right in the middle of a nice patch of sky that had opened up for us and unfortunately
the second night was clouded out but of course we had a great time i got to see some of the facilities in a little more
detail talk to some of the club members get to meet some other folks and learn about their experiences
so no matter what it was it was definitely a worthwhile trip now
i want to advance this here as you go in uh they have a nice little
painted sign there telescope's only beyond this point i thought that was a fun little aspect of the trip you know
the kind of thing you stick in a scrapbook or something like that but it kind of set the um
tone for the night now this was taken on thursday night of of the week of alcon
you can see it's a little bit cloudy that day the day before it looked about the same
and right around 9 or 10 o'clock as as we started heading into astronomical twilight it cleared right up and
according to the club members the seeing was a little rougher than it usually was but i found it quite okay uh compared to
the east coast and the skies i've i've seen there it was certainly a beautiful night for
sure but to talk a little bit about some of the the things they have there some of the club members had brought out their
telescopes some some of the telescopes just belonged to the club they had some big dabs there 12
16 inch i think there was even a 20 inch there and inside you see there's this nice
domed observatory where they have a 15-inch cave newtonian that they
put in this dome and they said it was quite the effort to put this observatory together but the observatory dome itself
i was told was actually a grain silo from a friend of theirs out in kansas
how they got it down to albuquerque and down there is
an interesting story i'm sure i'm not sure that they moved it in one piece but that's
that's quite an undertaking uh for a home for such a large telescope but i
did have the opportunity to look through this for most of the night on wednesday night they had it trained on
m11 the wild duck cluster and i looked in there they had a 100 degree eyepiece a 90 degree ip something
like that where it's it gives you that kind of space walking experience so that was really fun to to look into
and let the telescope do all the tracking and and reveal this beautiful open cluster and perfect resolution
now i got a picture at night as well as you can see uh the nice red lights in there you can see the ladder going up to
the eyepiece the focuser and the controls and everything like that
now because it was uh significantly brighter in the dome compared to the light of the stars at least that's how
the camera saw it i wasn't able to get as many stars in the background through the dome slit but i thought it was
really cool to get a picture at night of the telescope looking out through that slit it would have been at the wild duck
cluster at that time here's what the observing field looked like
you can see over to the left they had one of their imaging domes um imaging is a little out of my
experience but it certainly seemed like the folks over there were having some fun uh they had a really nice setup over
there and i'd seen some of the astrophotography they'd pulled out of their gear and it was absolutely
tremendous you can see there are a couple of dobsonians some large binoculars set up
until then the largest telescope i'd looked through was i think a 10 inch and it was the first time i saw jupiter i
had to be six or seven at the time and i barely remember it but this was my first time looking at a truly big telescope at
a deep sky object i got to see messier 51 in a 16-inch dobsonian and the spiral
arms were absolutely stunning it was the most detail i've ever seen in that galaxy by far and i certainly hope to
recreate that experience again but over the observing field you can see
uh what the sky looks like i'm looking east in this image so just
over the top of the frame and out of you you would have cygnus and the milky way and all those summer constellations
and down here it looks like we have a couple of satellites hanging around and you'll see this in the other images
there is this cloud bank that was kind of surrounding us maybe up to five six seven degrees and it stayed there pretty
solid for uh the few hours that we were out there observing but straight above our heads
we had a tremendous starry sky and it was the darkest i'd ever seen by far
truly an unforgettable experience here we go over to the milky way looking
south you see there's a little bit of light here that's coming off of socorro which is the next major city to the south of
albuquerque we were kind of in the middle between the two just off of i-25 and i know we all recognize this the
southern milky way stretching up in sagittarius now where i live at 41 degrees latitude
of course this is a little bit lower i think i had about maybe a little bit of a five or six
degree advantage by being down just past albuquerque so this was a little higher in the sky a little better place for
imaging and of course it was much darker so i was able to get this beautiful shot of the milky way uh the teapot of
sagittarius there uh the scorpion dangling down just above the sky
and then you can see m6 and m7 the lagoon nebula up here sagittarius
star cloud a lot of the wonderful deep sky objects uh that we tend to cruise with
binoculars and small telescopes and sagittarius and scorpius they were all visible in that image and i was really
satisfied with how that turned out and then later on uh at a later point point in the conference
you can see there's this little bend of stars down here that's corona australis
and i'd never seen that constellation before so it was interesting to escape where i so normally observe at
the 41 degrees and get a little farther south and get a little bit better sample of what the southern sky has to offer
down here as well as a better view of some of these targets which are normally low in the trees or
low above houses and kind of hard to see where i live the next image here this is kind of
looking west southwest you can see socorro is down here that would be off to the left and i didn't see this until
i loaded the images onto my computer and i was quite surprised with what i found down here is actually a thunderstorm
with the monsoon season and and the flat layout of of the way western new mexico is
you can see for maybe 20 or 30 miles and there were some thunderstorms to the south and that's actually lightning in
the clouds there kind of uh backlighting these this this little cloud bank just
above the mountain and that was a really incredible experience i've been trying a couple times throughout the night to get that
on camera by centering it uh it wasn't seeming to work out so well so i thought
i'd just get some images of the stars and i thought i'd get this with the mountain of in the foreground that little silhouette there
but i was fortunate enough to get that thunderstorm over there which was really a nice addition to that image some some
icing on the cake and then we go back to this dome where they had the 15-inch newtonian
of a good chunk of the milky way right over that and this is probably one of my favorite
images you can see it's behind me now in my my zoom background um this should be looking through uh
cygnus right here here we have the neb uh here we have aquila the eagle coat
hanger hanging out up here and then just a couple of clouds as well but you can tell it was pretty transparent
and uh for for something that was not much more complicated than a point and shoot
with my camera i have to say the sky did all the work it was really a tremendous location
here we have another shot i thought i'd be a little more artistic instead of looking for something specific
uh but here we have the big dipper just over um oh thank you
i have that just over the dome of the observatory um it kind of looks like it's you know pac-man eating something
up um with the dipper just kind of hanging down in that slit but there's the dipper extending up
uh ursa major kind of falling behind the dome there kind of silhouetted um a little bit of light pollution in
these clouds uh but it does have some artistic effect there it didn't have much of an effect on our seeing or our
transparency or kind of washing out some of the deep sky targets we did have some really good seeing at least in my
opinion uh compared to much wetter and more turbulent eastern skies of places like
pennsylvania and virginia west virginia all up and down the east coast but anyway here we have the big dipper
and at this point i was wondering i have a dslr and a tripod um i've never used
the really high iso settings before they never had a lot of use to me for these kind of wide field nightscapes
but we all know messier 51 the whirlpool galaxy is right there and i wanted to see what would happen you know if i
could just try and get that so oh it's not on this slide but the next slide here we have m51 and you can
tell it's a pretty grainy image i've enlarged it and blown it up and enhanced the contrast as best i could
certainly not the best image of the galaxy but i thought it was a fun experiment to point the camera where that was and see these little pixels of
m51 and its companion galaxy in the dipper i didn't think i'd be able to do that
but i set myself a new photographic record at 23 million light years for the farthest thing i've ever photographed
and regardless of the quality of the image i thought it was a fun exercise just to test out my equipment and see
what i could do but i want to go back to this slide this was one of the star trails i did
and when i was looking at this in photoshop later on it was a little bit blurry because the milky way that's been
blurred over just like the stars and normally if i were to take this in a more light polluted sky you'd just see
the stars streaked over as normal but you see the clouds were moving the milky way was moving
all the colors were brought out over this exposure and when i enhanced the contrast i get
this kind of pastel effect so it wasn't as i guess you could say scientific as the other images but i
wanted to be a little more artistic with this one and blend everything into uh what almost looks like some art so you
have socorro down here and the clouds and the thunderstorms the milky way stretching out over that
you can kind of make out the teapot of sagittarius and some of the different clouds
there would be antares right there and then an airplane that took off south of us and was flying up towards
albuquerque all captured in this image which i thought looked really cool just a nice combination of science and art
and a lot of us talk about ways we can combine that and i think i found uh one image like this one that did that
particularly well i was pretty happy with how that turned out so with all that said the
astrophotography was great the skies were great but certainly the people were the highlight of me attending alcon i
was thrilled to meet so many faces friends i'd seen online meet them in person and it was a pleasure to meet
some new folks as well but this is a picture that i think would look familiar to to many of the gsp
audience john briggs has been on many times before talking about his astronomical lyceum and i had the opportunity to
visit that on the last day of the conference and for those of you who are unfamiliar with it it's a collection of historic
telescopes and memorabilia books magazines spectrometer
all these different things that john has collected as a member of the magdalena astronomical society and a classic
telescope organization as well i could never deliver the astronomical lysenium the
justice it deserves john certainly did a great talk when he was telling us about all
the things he'd collected and preserved over the years but that was a highlight of the trip and like i said no man could do that better
than john himself but he's talked about it many times on this program before and should you find
yourself out in magdalena in western new mexico this place would be worth a visit
and i've included a couple shots of the very large array as well this was along with that tour looking down the double railroad tracks
where they have crawlers a little bit like they have at something like kennedy space center where they mount these
giant rockets or in this case radio telescopes onto this crawler and they move it over railroad tracks to
different locations so essentially how the vla works they have a
triangle of telescopes so you have 13 mile stretches of rail
uh all separated by 120 degrees pointing in different directions and they're able to move the telescopes
out along these rails there are four different configurations that change the resolution of what the vla can do and in
this case it was in the deconfiguration which means it's closest all the telescopes were kind of nestled
in the center and a little fun fact for those of you who have seen uh the film adaptation of carl sagan's contact this
is the orientation that the telescopes were in when that movie was shot mostly because they were so photogenic
but it was kind of cool to see them all together and get some other pictures like these where you can see them clustered with storms in the background
as you go into the vla it's this vast plane kind of surrounded by mountains it's almost like a crater
or a bowl shape and that's intentional because they pick this location a lot of
the radio noise from our cell phones and our cars and all these different things is blocked out by those mountains and that
a lot allows them to get much better observations so as someone who hadn't had much experience with radio or radio
astronomy it was really interesting to learn how they had done things and watched them do their observing in the
daytime just move the telescopes around and point this array around and do some interesting research
here i got a little bit closer you can see all the dishes pointed in the same direction
and then we have another dish they have 28 dishes in total 27 of which are divided among the three
rails this one is in what's called the bird bath position so essentially they point it up directly up and that keeps kind of
out of the wind as shelters as as best they can do and you'll actually see this when they
get more wind than they usually do so when the wind gets up i think it's over 30 or 35 miles an hour all the
telescopes go into this position now radio telescopes like these can observe in almost any conditions
but the wind is a major threat because it can start to cause forces and start to distort things and possibly damage
the telescopes as fragile as they are so they put them up in this position to keep them safe
and this was one that was kind of set to the side for service and that was really interesting to see
now i moved on to one final array i have just a couple more images this is the vlba which is the very long
baseline array and this is a series of ten telescopes that extends from hawaii all the way to
the virgin islands and there's one as far north as i think of vermont
it might see the sun sitting down there all right the dish
right in the background everyone
um daniel i think that you've just logged on can you mute yourself uh yes
okay all right thank you all right all right is everything good so far the
the audio and visual and all that yes it is okay it's great it's great
so here we've got the very long baseline around like i was saying it's this huge array of telescopes and similar to the vla they tend to
point them in the same direction and get kind of a 5 000 mile long uh array of
telescopes that they're able to image things and study things with all these different astronomical objects uh that
are very bright in radio sources and this was just outside of pi town which we were going to to see
a 40-inch dobsonian which one of the magdalena astronomical society members had built that was james totoritis
oops here we go let me advance i have another shot of the vlba dish
there the one in pi town and finally a couple pictures of the 40 inch
that we were brought out to see out in magdalena you can see there are three different images here of the the telescope in
different positions it was a little bit cloudy that night but fortunately i was able to see the ring nebula through it
uh even though the skies were kind of partly cloudy i'd never seen it that bright before in a telescope i mean a 40 inch is truly a
monster you can see the people standing next to it for scale and i'd never seen that kind of
definition and outstanding brightness from the nebula unfortunately i couldn't see much detail because of how cloudy it
was and soon after i stepped up the ladder it went black but western new mexico and even albuquerque
itself as urban as it is was a great location to to meet so many other to meet many other astronomers and
get to know some of the alcon officers and gsp members and and get to know a lot of more
a lot of amateur astronomers that we have seen online for for so long
uh i know many of you have met in person but it was my first chance to get down there and and see some new people so it
was certainly a joy and i hope you enjoyed the astrophotography and some pictures from
the great radio telescopes of the west vlba bla and even this giant optical telescope
the one out in magdalena that was a 40 inch so thank you very much thank you that's
great i i'm curious um connell was this like some of the darkest skies you've ever visited
they certainly were um i've been out to darker places before cherry springs uh
which has black forest star party um i've been out to cherry springs before and those were pretty dark skies i
enjoyed that quite a lot uh tas's site uh south of albuquerque about an hour and a half that was very good
but the elevation the dryness uh even the remoteness of western new mexico i've never been that far from
from civilization you're really getting out there like i had with that picture of the dirt road
that beat cherry springs just by a little bit because of how many factors uh
work in those locations favor i mean cherry springs is a great place has some good elevation some good darkness for
pennsylvania and the east coast uh but when you get out west and you're eight thousand feet up and it's 30
humidity and there are no lights for dozens of miles that that all works great transparency
all of that yeah that's right absolutely awesome well your photographs were awesome very inspiring and makes me want
to go back out there and wonderful wonderful thank you very much for sure
okay um connell thanks again uh up next is uh
uh nicholas eric aries and uh otherwise known as nico the hammer and uh nico you
want to come on hi scott how are you how are you guys
well i hope you are you are having a great night a great gsp and
and tonight uh well you know last week i was talking and showing
how i captured saturn from my home with the with the dops onion yes always
and this these few days i was working with a
jupiter we are we are months ago maybe to the
opposition but uh i wake up really in the middle of the night maybe at 3 00 a.m
and take a shot of jupiter because we we was having a good seeing
nights this last week that is is not normal in this
in this time in the year and let me show you the
results okay are you seeing my screen yes
okay as as always i will start showing you
how i i i did the the capture this is one of the the videos you can see well this is my
my hand tracking shagging and and and you can see that
the scene was stable and maybe a little blur or a little movement but it was a really
clear night and as you know i used to to make
four captures for each image because i have the monochromatic
camera and in this time jupiter was with the the red spot on the front and we have
seeing looks really good we have io transceiving or just
about transiting the planet and uh here at the left
this this other moon is ganimed and i was waiting a good scene night
because i was to try to capture some details on anime so let me show you
the result of this video
let me see here and here you have the
four channels this target the red channel the green the blue
and the the light the luminance channel
and this is what i get when i sharpen with wavelets in in resistance wow yeah just
was stunning when i saw the the staggered images i said okay this was a really good night
and i was lucky that we have no clouds no humidity so i take
four four entire sets of videos so i i get different
positions of the of the transit of io and the
the the red spot and this was the the results when i stacked
under rotate in wing chup all the channels this was my the the first capture of the
night you you can see even not details but some
shape of io is like a little a little ball there
and [Music] and i also chase these two white storms
that are forming below the the red spot and the for the last month the response
is it seems to be moving down uh we are talking with other
astrophotographers that capture and make a planetary imaging
that uh it seems that the red spot is moving a little down or maybe the the contour is moving up
we need to wait to see what happened there and this was the second set you can see
i uh a little closer and
this was the the third set and you can see here
io in front of jupiter oh yeah it was
me going near the the red spot is i love the
the transits when jupiter has the the response in the front it's
it's really beautiful to observe you are watching with your eyepiece and you see five
minutes later and you can clearly see how it moves now not the
you don't see the the movement but if you wait some minutes you can see the the the change of the
the moons and and the rotation of jupiter is amazing and this was the the last one that i i
took you can see there again
and i make two two sets with with less
magnification magnification no no magnification with less roy you see when you capture you you can
[Music] set the camera to to focus on a
small area of the sensor or you can bring the the resolution a
little bigger and i i made two sets with
the the the two moons you can see ganimede here i really love this kind of picture
with with the moons and the transit and everything spectacular and
here again with io in front of jupiter and anime and i was really really happy
when i see this a little little details or or in the
shapes of ganime and this was the
it was the the great uh detailing i get i i always try to to get some detail or
colors on the moon of jupiter's and this when when i see ganimede i was really
shocked you can see here a little closer and it was not not only really real
funny to to be there and showing the observation and the capture
is really great to get this these images and and to show this is the
real the real moon on a far planet and it's it's really it's really
shocking when you when you think about the the distance we we always talk about the distance in
in astronomical distance but the we
we think that this the solar system is well this is closer now it was six uh 600 million kilometers to
a little bit far away is even bigger than the moon
so you can see is really really far but it's really really good uh to show
that even with a material telescope and with no tracking and
no equatorial mount and everything you can even get this kind of details
it's really good yes it's really nice nico just to remind me what what size
dobsonian are you using it's a 10 inch dubster
the monochromatic let me stop sharing i am using here here here yeah oh this
camera okay it's a guiding camera yeah camera but this works really fine
absolutely absolutely and uh the software you like to use you is
it i yes i was using for a long time a shark up a software um
for the last month or maybe two months i started capturing with a fire capture because
talking with some guy to talk with other guys we found that this especially camera
gets more more frames per second with some configurations that you can do
to the fire capture that in shark cap i was limited in that way
so i am using shark up when i try to get some deep sky imaging with this the same
camera but for planetary machine i am using the fire capture and then the
processing i use the all free software i use pip
to center the the planet in every frame i use a auto stacker to
select the best percentage of the frames to stack in one image shark up for
for the sharpening the details and photoshop just to make a few adjustments of colors
or fix the background sometimes the the blue channel brings your background
very blue and just for details i see i say that's fantastic stuff
you're you always uh uh present work that is so um
beautiful and uh and so detailed and uh you know i often um talk about you to my
astronomy friends because many people think that you have to have some of the world's most
expensive equipment to produce images like what you do and i think you have to have a good
telescope good mirror it needs to be collimated a good camera uh but you need great
skill and that's what you have and uh so thank you for making that presentation
oh thank you scott and i i love to to share this kind of thing that
what you can do when with the the scope and the camera that you have
you can do a lot of things and you keep learning i keep trying different
capturing methods different processing and you always keep uh
making up a new step uh so it's really it's really nice to share with this with
you and with the audience and as always if anyone has a question you can write
me or call me anytime great thank you thank you
thank you very much okay um
uh up next uh is um we're gonna stay down in argentina and uh we are bringing
on uh cesar brolo uh cesar has been working on
uh restoring the observatory project he's been talking about for the last uh few months
but they were finally i think able to get him to do some more work which is great
i'm really glad that someone like you cesar is out there doing that because preserving um our astronomy site
heritage is also very important thank you scott thank you very much it's
it's really great that you show um you you
make the the possibility to show us our works that we
return to the to the works again um we
have now a project where we
considering put in new conditions
three telescopes they all size fracture 10 inches
and they boost up highland refractor of seven inches and
we receive a donation and all an historic uh
telescope that for uh from an amateur astronomer in san miguel
their daughters a contact us one year ago and
then donate us to the association
and we are thinking in install this uh
30 centimeters near to 14 inches uh telescope
um in of course in in the facilities of the san miguel
observatory and if we have
uh these three uh these uh three telescopes working and
maybe one year we really we feel winners because this is a
we have had a huge a huge
work let me i can
show you some pictures some presentation
string
let me know if you are watching the presentation now
we saw the whole presentation yes of course
yes yes i i know that you sent us the best way to show slides uh
in in our zoom uh because it's actually helping yes i saw the video but you know
sometimes all people like me are more difficult to learn
the things but we told that from any a lot of uh um
global sub party we we uh called especially to the new ones when the people are um a little afraid
to show fans you know to share the screen and say no worry we call it that they say you are in the global safari
yes you have troubles to to share the screen you're a member of global support that's right that's how you get it right you
have to make those those errors absolutely it's a requirement yes yes absolutely
and we we started again i i tell you uh
because i tell you because uh we advanced more
in the things about the the situations where the
local government of san miguel have more tools to to take position of of the
facilities and we start to to uh to work um
now we can start to work especially painting the domes the first
thing and i can show you in this presentation something that i have
um the the first thing is is where where are they i took this picture
of um you know maybe i don't remember when but
we have a small eclipse solar eclipse maybe nicolas do you remember was in the in
the summer but i don't remember when um in december in december thank you the yes a small
part of a sun but i couldn't take a picture because you can see that we had
a beautiful uh sunset without we closed but cloudly i never
we can took the we can't took the picture of the sun with a little part of
the moon but i can show you thing you can see my my
cursor here is the size is the size in this
first of all that i can i can explain splat explain to the people is that here is a
celostato here and here well in this part is where
actually is the um size
of 10 inches telescope refractor telescope yeah okay refracture is the big one
really is a treasure it's a threshold because this is uh [Music] 254 millimeters objective yeah
work like an ed is a instead of lead out of left
but they used a very low dispersion glass and it's very interesting because
uh it's no more that an f10 it's very short for the because maybe
you know you know skoda that uh in the in the end of the 19th century or or the first
time of the the 20th century
uh the 20th and 20th century uh do you have more 15
like ff race or focal racer number uh
in construction size or for a early gusta would stop hiding that
gaiden was buy it bad size and this size telescope have
a a focal uh racer of uh focal ratio ratio
sorry of um i don't remember maybe it's a it's very
short for the time maybe it's a it's it's a telescope from
1920s maybe um we are um [Music]
as we are watching uh and we are start to cleaning the objective and we have
some signs of in an informational in the in the cell of the glasses
looking forward i ca i i can give you this information exactly of the
focal length um of course that we disassembly the part
and we keep in a box like a really a real treasure
well here we are starting this is the the the the pier and the
and the equatorial mode of the gustav height and gustaf island we have two telescopes uh
together uh one of seven inches and another one of
uh five inches um
work really good and in good conditions they are the clock
work very very well and we are thinking without
remove the clock you know we are thinking input uh
two stop step motors in rec in
right ascension and declination
here do you have the motor yes yes tell me the motors uh is that a weight driven
mount uh the the motors are a stepper motors
with the higher high torque yes high torque nema motors
um it is it is the first one where we are talking about to put
[Music] a ps pmc a system to drive
the problem is that in the declination we don't have that answer that
as is typical in this telescope we don't have a
will and a worm because they use you know the system of
uh something like a pivot bible with that yes but we can
our idea maybe it's not make a go-to telescope if not a driver for
we are thinking maybe in some type of things about some encoder or
we are thinking how how resolve this maybe we can make we can put uh uh
in this area um for in declination we can put uh here
where where we have a wheel we can have a
worm and an um background and
well we don't know but but our first idea is put a system where you can
you can uh choose between the clock the old clock and a stepper motor
with high torque of course but very precise for for the
um maybe we can guide or you know we are thinking and hope
prepare this well something that was very important to to make the first step
uh was make a safe door it is not astronomy it is
it's something where you you need put the same step the first step
and here is um here is the director santiago mayesi
working too uh in in and he's a here you have a
i a went from from from the you know uh from the the government uh to to to
support us to work you know um um and here we have first of all from one
year ago we have a metal door safe door because we have problems where
some vandalism and now we have yes something that is very important we have doors
strong doors and alarms this is very important here you have a
view of of the the dome and the the smaller telescope the the
second the secondary telescope that this telescope is is uh of the
the telescope of five five inches and was uh to use
to put a photographic plates
here is the people enjoying and here you can see the the secondary and the main telescope
here you can see in the more details the the the amount
if we can put um um how do you say if we can put a
will um will and warm system here
we we are winners we feel really very happy
i think that we can we i saw that really we can we can do it this
well i i go to change
to share another part of the screen let me
[Music]
[Music] wait a minute sorry no problem
cesar we asked everyone else in the uh program what
what really blows their mind about astronomy
you know exploring the universe what is it for you what what what is so amazing to you
for for me is uh now is is the idea of
of uh how the gravity gravity uh can
uh distorted and change the the
the gravitational lens gravitation yes where do you have
nothing and nothing is pulled by the gravitation like like a jelly like uh something that
don't have sense really really if if i start to think in
my idea of of uh how how gravity because
if you can say oh the space time
or something say is for me the idea is fantastic because
it's for me something about new beginnings new uh to
understand where you have nothing to pull because
how many molecules of hydrogen or do you have in the emptiness and this
emptiness is totally crazy how is bullet and default and
change the shape where the light because for me the light is still going in
in the right way but you know sometimes it's like you need to
feel like uh like a train yeah the train thing that is going ahead
in a in a in a in a line um but
uh the train is i think the train don't have a a will to
to change the direction uh but you have
the idea where all all lines are totally going to
different places uh to go uh are
bullied and change the shape
by by uh totally uh how do you say totally um
uh invisible forces is is it's amazing
yes yes and and yeah gravitational lenses are
something that a cosmological friend that they have tell me for example something that's so crazy like
in a part of a picture uh of uh of the gravitational lenses of chance
shane's web yeah you have the same galaxy it totally
how do you say totally distorted distorter and you have a part and another part and they put in
they make interferometry between up one part another part and
they have different measurements of distance
because where do you have the path of the light more longer longer sorry no more longer
longer uh do you have you need the life needed more time it's totally
amazing it's totally uh over or i
um i can share you a little more but for in another
and this is the the telescope that we uh
this is another uh guide of the group nicola valvey
nicolas is an archaeologist and he went to to
he went to variloche 1 1 600 kilometers in
in his land rover ship to to carry the telescope and this is
the telescope that we receive um uh asked
us to use of course that something something um
something uh funny was that nicolas told me oh caesar is a great piece for uh for
the museum no no it's not for the museum we can use totally
the thing between the thing between uh the thinking between archaeologists and and opticians and say no no we can use
completely we can put in a mean condition and use totally totally act uh in in a
in in a grey way to use let me show you more
okay well here you have the pieces and we are
finding we need to to make uh another uh
another part of this because we have the all the declination mode
modulo and we need another one that is for for a right ascension
you can make a a really big dope sony and you know caesar ah yes but yeah
yes i know i know but as uh we we have an empty
dom um we have another another mirror for for dobsonian
but this one we we think that we need uh respect the the original design
and yes and really we need to to make the the
this like like a a a totally functional telescope yes
the corresponding restoration yes absolutely because because uh
is is a is a great telescope to to you know to use for astrophotography for measure
and 30 centimeters is a great a great telescope to put in works yeah here the
here this is the the finder uh this is beautiful because the the the
owner uh was a a beautiful man you know the beautiful
kind of people and and something wonderful was that the daughters
[Music] really think that in in donate this telescope and we can make a great
uh work and of course here we have uh the opportunity
well we we need to make another pair of this
because something that you can you can see is that nicolas is archaeologists he use
uh the archaeological rules that using in for for
digging and excavations and it's very interesting because it's it's a great
way to show the size of the things
this is the the mind soul is from the 1945
1950 i think this telescope the the owner made okay complete
telescope wow the optics here yes yes
he made the the optics and i i here do you have a picture of the
original setting oh yeah and we need to put in this condition the
telescope yeah or better because we are going to make a go-to telescope yeah
it'll be better i'm sure yes absolutely we are thinking in make the tree
telescope sorry the tree telescope at the same time because
it's cheaper and we can put all in the same way for example sun
to the the the painter uh to the painters uh or uh all together
with the tubes and disassembling the things the the all mechanics things that we need in the tree telescope
is much better make all this for for the the
the three telescope here in santiago mayesi with santiago last year we disassembled
the cell of the size telescope because the circuit was vandalized here
we have a worm and on a wheel
and here we are going to put um
going to put the the two stepper motors and it's more easy to make a go to telescope
and here the problem is that we need again the
system the back focus completely system i think that
i saw maybe in our friends of friends of
historical observatories that made it possible to
to recover uh some pieces that maybe they have or
somebody told me that maybe it's possible to to get an another
similar part and we can adapt especially if it's a size part you know or all about
schedules and no sorry schedules it's the drop sketch uh um
[Music] plans about the the about size or design
is welcome because we need to to make a new back focus system
um and we don't have money to of course no well maybe yes i can afford
and i can help but we need more help to have to make a very
strong and because it's a it's a 20 20
it's a 10 inches telescope you know you can see that this is for public outreach um
maybe you can put together a web page where people commit yes yes and we'll we'll we will help to absolutely
sure yes we we are awaiting uh the permission of the
government to to to have
the condition the the vicia vital cosmos that's it that is the
the how do you say the association that to to have the
legal condition to receive healthy receive donations yes absolutely when i
have that i'll advise you and we prepare uh completely
the things because all about materials and of course that i
am important in argentina i am thinking how uh import without problem with rece
receive the some materials without a
as donation the problem sometimes is that custom here is a hell
and it's terrible and you say you receive this this is a lot of countries you need to pay by donation but prices
every every time i remember the customer that received the donation the
price of the the eyepiece from from from explore scientific he needed a
paid a lot it was it was incredible of course that he loved the piece and he
had the pieces more than i i i need to pay taxes like
as a new ips is ridiculous it's crazy
yes and this is very important to to think how ho work um
well you know it's this it's a great this is this incredible cell
incredible cell of size yeah it's amazing very heavy
oh yeah ah yes i love them made to last yeah yeah yes hi adrian how are you
i've now switched to my home setup so ready to
go and uh making sure everything's working and everything is
here you can see that the two yes here you can see two
254 millimeters it's incredible size objective is it's a
piece of art yeah
you can see the number it's beautiful beautiful yes
yes i prepared a new a new presentation next week with the pictures
that i took in my laboratory of of the the glasses cleaning you know because we
are starting i'm here totally amazing with this look the size
of this it's me yeah
we with uh santiago mayesi we was working
completely from the noon to the to the afternoon and
near to the night six hours to remove i'm making a little
nose to to remove each screw very handy you know sure
was a craziness we remove uh um
how do you say uh not the beast another one i remember i i forget the name in english the hornet hornet nest
yes okay i remember the old one fortunately without the name
i've got any living ornaments yeah yes but we removed it
let's see well this is my presentation okay
all right for tonight and here something that was really fun
okay really we say we don't um we can't fight right now expect to
expect to to make focus uh
here is santiago mayesi showing the the telescope with the sun and making focus
of the sun right now is a very well known astronomer from
south america yes he is yes
well this is my communication we can hear you just fine over here thank you very much to have a space like
me thank you very much okay all right so we are going to um
uh from argentina back up here to arkansas uh and um
uh we are going i'm i think maybe uh to
dr daniel barth's uh property out there yes hello all right
so looking forward to this one how are you good good you got good video
good video and we are out here in the dark with uh
i'm hoping you can see this with the edge of it i think it's a pair of
big binoculars right yeah that's that's my pair of uh very large binoculars those are uh five
inch aperture and i'm trying to adjust the light here so they're visible yeah but yeah
we're out here with my students uh folks you want to say hi to everybody
community around the world [Music] they're so enthusiastic oh come on can't
we say hello hey guys from argentina so uh we're out here and we're doing our
very first uh live astronomy lab okay here at uh lovely barthland ranch and
observatory and uh i have a hilltop home up on what's known as round
mountain and uh we have about six acres in the backyard and we're screened by
hills and trees from the lights of nearby cities so we've got the milky way as a naked eye object and we're just
starting to pick out uh scorpio and other things and do some constellation sketching
but the theme of the star party the global star party is beginnings and uh i
found a beginning in the news that i was just so excited by this is something we've been waiting 50 years for or more
and many of you go out with your telescopes and you take a look at uh
you take a look at jupiter and its moons or saturn and its moons and people have speculated for
many many years that jupiter's moons were co-formed with the giant planet and the same thing with
saturn's major moons how could jupiter capture satellites as large as
europa iowa etc and uh really very very difficult for
a planet like that to capture satellites so big people figured out for many years
the speculation the theory was that there must have been a
circumplanetary disk a disk of dusty material orbiting the equator of jupiter from which these
moons would have condensed in exactly the same way as
the planets themselves condensed from circumstellar disks of material
protoplanetary disks as they're often called and we've been photographing plural planetary disk for about 25 years
uh hubble captured one shortly after it was launched and people were like wow look
at this protoplanetary disks and there's gaps in the rings ng with gaps in the
rings that must be where the new planets are forming and kepler satellite bore that
out etc now the atacama large millimeter array the alma telescope array down in chile
they have detected the first circumplanetary disk which is so very exciting so
this is around a giant jovian and there's a disk of material and there are
gaps in the disk which indicate large moons like europa like ganymede
like io forming there right now and this has been we've scott we talk
about this on my how do you know program many times the history of science is often competing theories
and one doesn't get selected or decided upon until we have the technology to do
the experiments to gather the data that says yes this is so
this has been a beginning that we've been waiting for uh for
people been speculating for more than 50 years and we've been looking for this heavily for more than 25 and uh
we find that the uh hubble wasn't quite
enough and webb could probably do this but hubble wasn't quite there yet
and the atacama large millimeter array is actually seeing this uh this circumplanetary disk in the microwave
range so this would be within the range of uh webs far infrared cameras but
we'll see and maybe webb will image this one day and we'll get to take a look at it in infrared
but that's a beginning we've been waiting for it's like waiting for this actor to come
on in from the wings for such a long time and it's finally here so this is very exciting and folks i'm
going to keep this very short because my students are here tonight and they are my priority
and uh i'm so glad thanks for coming on i'm on a student's iphone right now because my phone didn't have the
reception yeah to look in so i was able to send one of my students a
link and they're very generously letting me use their phone and i'm not in my office we're out in
the in the deep dark and the sky is fully dark now so we're going to go back and enjoy the constellations and wish
everybody a good evening excellent tell madison her contribution to science is
greatly achieved or has been achieved and is we are very grateful well i will let her know and uh thank
you all very much and we'll talk to you soon i'm going to get rid of this bright light i'm drawing bugs like crazy good night club hey good night have a good
night good night everybody hi everybody enjoy that night sky out there
no grumbling no crying
so anyhow um uh adrian i uh i've been asking everyone else i didn't
have a chance to ask daniel barth but uh he often tells me what kind of blows his mind about uh astronomy and
his own uh views of the universe what what does it for you
well it's um whatever it is it makes me drive two and
a half hours on back-to-back nights to go and see it right it's
i was thinking about it on my way in um because i figured you'd ask the question
scott and uh yeah i think the i think the answer is knowing that we belong to something
a lot bigger than ourselves yeah um i think that
you know when i image the night sky against the backdrop
of things on earth or you know nature like trees and lakes and
things it's my way of showing that you know we're a part of all of this
this isn't an unknowable you know background
it's it's more than a background tapestry it's more than um you know stars that are distant
you know pumbaa has it right they were a giant ball he thought they were giant balls of uh plasma
and um and yet so as timon they were you know whatever timon said they were i
mean they they're everything at once um until we finally developed the technology to fly close to one
um we have to use you know other other forms of science spectroscopy and things
to know what they are we study our closest star and at the same time there are um
you know the the ancient traditions and um
you know the the ancient views of stars what they meant so to me it's all about a belonging
and for me kind of a personal new beginning is that um
one of the favorite places of mine to do uh nightscapes
the keepers of the lighthouse basically said yeah we would love to
have an an astronomical event out in our um you know out at our lighthouse park
um they they apparently are aware of how dark the skies are there too and i told them if not this year i would
definitely try and arrange something so that we could
have a dark sky party there and it warms my heart because it's one of my favorite places to go
and um i will go ahead and uh share a screen so that i can
pictorially share um you know what i mean
when i come out here let's see first i'll share the um
i'll share an image here so this is what it looks like
um these bright lights this is the lighthouse and you would say well there's no way
you could do any kind of astronomy outreach here
well i was told how to turn those lights off and they you know they said they said
come on out you know whenever you want to shoot and so this next image
i turn you know the lights are turned out look at the difference you know with the lights out
look at how much more you're seeing i didn't intentionally frame this for the lighthouse to be looking at
andromeda that's just kind of how it turned out you have the andromeda galaxy here and
you have this part of the um cassiopeia region where you can barely
make out cassiopeia and down here is the light of m33
sitting next to this lighthouse so so it was it's a thrill to be able to
come out to have permission to turn the bright lights off we can't
turn off the lighthouse because it's got a important function it keeps shipwrecks from happening
but um but we can still turn off the camp basically the park lights
there are there is some other lighting out there and i can demonstrate that with
this image you can see that these that the lighthouse is lit by
all sorts of other lighting coming from behind me there's a uh
there's a stain quarters and see if i got those numbers yeah 1857
when the original lighthouse structure was built um so it was uh there's lighting from a
building behind me and then there's campers there's a few campers left
that are camping out at this park so the light is still
it's still light paints when it's completely dark there's a couple of lights
that are still on and the lighthouse glows a little bit red
because of a red light that's behind but that that red light's being overpowered right now but you can still see
andromeda here the heart and the soul the double cluster
um and other other objects here that are part of the winter milky way and over here the
dipper slot the dipper slid in now you know you're at a sky that's
really dark it looks this is maybe a level darker in pictures
than um if you were out here and you were trying to find the little dipper it would be
difficult there's your north star here but as difficult as it probably would be to
find a little dipper in this picture it's just as difficult
when you're looking over the lake and
the view looking over the lake has this look and notice that there are
clouds and they're dark which means you're looking out at at least a portal 3
zone eventually i will get a sky quality meter but the clouds tell the story often and
when the clouds are dark enough that's telling you
that you're you're in a dark enough zone to where you know the you're in the darkness zone
where the milky way shows up his naked eye and it's why i like this place a lot and
so to be able to composition too yeah this was i did a lot of that with the trees you got a triangle here yeah i
purposely yeah i purposely composed did some geometric uh composition here sometimes i do use
some of the photography techniques um you know if i want to
if my imagination sees this sort of composition and says hey we can put the
milky way in between them here another good example of that uh turning up and looking at the milky
way here's another it's more of a compositional thing but you've got
all of these stars in the sky you're looking directly up so you've got the trees surrounding the
lighthouse um you know there's a little bit of a
blowout here on the buildings but um but it's okay and if you remember from
some other global star parties i like to look for certain features
in this part of the milky way to see if i've got them and like that barnard's e
did just show up um m11 the wild duck is right here
this little clump of this little smattering here and you can see there's a little bit of
trailing there's names for these uh these these are next to my list to
get names for but m over here with m
17 and m 16 and back further would be m23 right here but um
where i was standing you know this was this is the sort of so there's
there's some compositional things i like to do at the lighthouse and here's another one where
you've got clouds some bright lights which you also have
and i do believe these these are just artifacts i don't think those are actual objects
sagittarius is here and that where my hand is is m22
barely shows up so while tracking may not have been the best a lot of what i did with the
compositions here was to um i did a lot of framing that's nice
yeah you you have a really good view of what this camping park looks like
this is the uh yeah for once i didn't look out and over the water a lot when i was there
um i do have plans on doing that later but uh that's why i like to shoot at the
park and it's it can be a wonderful thing to um
have a place where you're welcome to do night photography and when i turned the lights back on i found that
there was some wildlife photography that i could do there as well and they're the raccoons looking for
food i believe this is the mate just sort of sitting here waiting
for mate to go out and find them something but that wasn't the only place in one
one more quick looking up at the uh the cygnus region
the cygnus region is important to me because it is just as bright
as the galactic center and it is also
um yeah it's a beautiful part in the sky and there's a the great rift starts over
cygnus in this part the great rift um a huge dust lane
starts here and goes on through towards the center of the uh wow look at that complication that is totally cool
look at yeah looking up and seeing all those stars yeah so
powerful yeah and that's like that's like a giant refractor aiming it
yeah it really does and if you notice the uh light beam from the light yeah you can see the
rays coming out yeah points at something um some of it most of that it was kind
of by accident but i'll accept the uh how it works it's basically pointing at deneb in the seder
region yeah as if to highlight it and say you know this is yeah check this out check this out
and somewhere in here i don't think i yeah right here if you can but you can
barely see there's a little bit of the veil it's very faint and
oh yeah yeah it's very faint and it's you know but there's a little bit of the veil there
and um you just sort of you have to know that it's there to be able to go oh yeah look at that so
that's and a lot of it when the sky's dark enough you accidentally get things like that in
your composition or you know if you're shooting in the right place so that wasn't the only place though i
went ahead and there's a dark sky lodge and tavern and i tried to frame it
um the barbecue here is very good and i tried where is this again
this is in the thumb of michigan this is in port crescent okay it's uh there is a
dark sky park that is there that about the same if
similar if not sometimes a little better darkness sometimes the point of bark
lighthouse has better darkness sometimes this area of the thumb
has better darkness but it's um it's a nice place they have a bridge
that if you go through here and if you decide to go through the trails you come out at the other end
here you have the dipper trying to sneak in here you need to go back there so that when the milky if if the milky way
would cross right in the middle of that you know yeah that would be the cygnus region will cross
the middle of that but the shot that i wanted it's
i didn't go once you come out through this it's pretty here i did some sun i captured some sunsets
here yeah and i would look for the cygnus region will be where the sun is
right there and i did i'll show a couple i did go ahead and do some sunset pictures
that day and i had vowed to come back to shoot at night well
i looked at this and i said and this is a different take i looked at this and i said eh maybe not tonight
and and i left it alone but i do have every intention of walking back through
that trip because i've been on the trail so i know where to go just need a big bright flashlight if
it's just me what i did instead was um i got to the bay so i showed you the
picture of the bay this is saginaw bay now if you go towards where the sun is
you see this bar right here behind the bar is a dark sky park port crescent state
park and so that's where i went and that's where i took this
picture you have the beach behind where
we're now on the other side oh look at that and i was able to get a two-minute
image yeah i love the sky yep i picked up the sky glow yeah i've
seen it's got all this drama from the milky way uh but it's got this beautiful line
of composition coming in from the water and then it goes into these pastel like colors
everywhere you know and then diffusing into the night with stars ablaze everywhere that's just
really really beautiful well i appreciate that scott and um
i mean even using the light pollution to effect with these trees um this is a composition
and there's a little bit of uh of some halo from
a two minute version of this image but i've left i've put the um
you know the other image there are a couple of easier ways to get your sky
seamlessly involved with you know a still shot of the ground
um sky replacement is something that a lot of folks will use to take the marry the two images
together so that they can get this sort of detail you can get this sort of detail in two
minutes a very solid two minute shot gets you
these stars and these dust lanes there is some processing that you do
with your um with photoshop to highlight the dust lanes there's the great rift
that starts with cygnus and goes through to where we can't see it anymore because
it's going below horizon and through the light pollution the difference a striking difference
between light pollution and sky glow stars shine through sky
glow easily in light pollution however um stars do not shine very easily
through that and so there but you can still use both to affect especially if you're like
highlighting these trees and the kind of where the milky way and the trees are
there together and then you've got again this is this is a
an image that basically shows that you know the cosmos we're part of
the cosmos yeah we're in the cosmos this isn't just
a background it's every bit for me these stars in the sky and there could be worlds around each
one of them so when you talk about reducing stars or removing them
you're removing you might be removing an earth-like planet somewhere out here that's right you know
in the you know that if we knew that
this little star for instance if we were to if we were to look for this star and
then we were to say okay this one if it's discovered to have a word an earth-like world around it
you know then that makes this image you know imagine what that means that
means we're looking at another earth-like world so that the possibilities are there we have we've
found a lot of exoplanets that are candidates you know we've yet to [Music]
discover one and maybe with the help of james webb we'll discover a planet that has the same mix
of um organics that earth has in the same you know the same ratio so
so the hun is on but um so that's you know imaging the sky and
doing it in different ways to try and highlight one
places to go in michigan if you want to see skies that are dark enough to get images like this this is one of those
places it's port crescent dark sky preserve um there are a couple of dark sky preserves
in michigan i've yet to visit and they're on my list to show their beauty off as well
but my plan is to go back here um
we're going back this is a even steeper pano now imagine this scene
but nothing but stars up here and the milky way is setting over the water the cygnus region
somewhere in the middle that would be that's one of the shots that i'm after
but in order to do that i just got to get through that gate over that bridge and walk through
with my baseball bat if i have to whatever makes me feel better um usually animals don't want to mess
with you no that's true you just you know you walk through
you don't carry any food with you yeah i don't care any food i no food or else
then i might be inviting trouble yeah and so then once i get out here
it's a wide open sky i can set up a i can set up this same composition if i want to do a
panorama i would have to do it in increments i find that you can do a panorama if you
um shoot 30 seconds each just long enough to get the sky there's a number of ways
to do it you really you can do it any way you want you can do a two minute exposure
another two minute exposure but just keep in mind that the sky moves
so whatever exposures you decide to do you know they just need to be
[Music] if you go to stitching together there just has to be ways for any software that stitches them
unless you do them yourself in photoshop like um gary palmer who's an expert at all kinds
of um these things gary palmer can manually stitch together
a panorama and make it look as seamless as this looks and um
i use lightroom to do that so this is that's one of the shots i'd
like to take at night and i've shown this one that's another one of the shots i'd get on the beach here
this is the sand bar there's the pitted bog river and there's the uh saginaw bay
you know which empties out in the lake huron and um
take a picture here and uh so that those are the goals
and let's see yeah that's that's basically it that's all i've been up to the last
couple of days and um i leave you with
this picture of me waving at an old stadium we get to play
at in detroit and just say even anything that's been built
that's a part of uh whether it's been built by hand or it's been built by nature
um you know all made of the same elements same stuff
and stuff so whether it's a modern park like this
everything you know everything's a part of you know there's the moon so you could consider this an
astrophotography shot right even though it's uh
it's an old pitch a picture i took of the rays you got that bright star over there too yeah and you got the bright
star that's illuminating i didn't get the disc here because i shot this with an iphone and then i tried to
process it and so you have um yeah you could consider almost anything
at all if you really broaden your horizons almost anything can be
considered astrophotography or landscape this would be considered urban landscape
and uh at the time the rays were ahead that the tigers ended up coming back and winning
but um but yeah so i'm going to go ahead and end the
presentation here so deep dee can uh yeah can come on but uh
i'll let everyone know how my uh foray into the uh unknown
and if i get those shots that i want to get or not and um yeah you were you were definitely
uh uh blowing your audience's minds with their with your
nightscapes so thank you they want to buy some yeah i launched the website so i'll put
that in the chat and then skype yeah i'll copy it and send it over yeah
good for you yep so that's that's my new beginning as well all right it's
uh it's https adrianbradley.photography we managed to get a domain that was to
the point no dot com no dot org or what you normally see it's just adrian
bradley.photography and there are a few prints there will be more prints coming
especially those that do well social media will likely become a print that goes for
sale so uh for those that are would like to purchase
some of my work i've finally created a vehicle for you to do that and um
you'll be able to go to that website adriennebradley.photography if you're interested in purchasing
now if you see something a global star party and you're interested in having it on the wall i'm there's no shame plug
um i will work with you to get it on your wall absolutely absolutely so we
can you're going to sell a lot of work there so i i would love to but more importantly scott thank you for
this forum which allows us to talk about what we love which is astronomy and all of its forms
and um it's it's quite an honor to be able to just share the work and it keeps me going
while i go out and get all of these pictures because it's my contribution to
[Music] astronomy outreach it's the purpose for the pictures so yeah it's great
thank you okay so we are we're going to move from uh
from michigan and now we're heading all the way around the world to nepal and uh
young miss deepti ga tom is joining us once again here on global star party dt thank you
thank you for coming on again
good it's all been good i like your uh space themed background
oh this is
[Music]
likewise uh biology chemistry and etc so i was studying about the impact of
astronomy autopsy uh how it is impacting all of this likewise in our daily life
and today i pick up the topic about astronomy chemistry like how the
chemistry and astronomy are related with each other so i found something from my studies
myself and so uh i'd like to begin first of all uh
let's talk about this phenomenon chemistry or here is uh we know that from astrochemistry and
we can study of the abundance and reaction of molecules in the universe and the interaction with the
relationship it is actually quite a lot of chemistry used in various uh areas of
tsunami our weak application is in the identity of spectral lines uh it
filament and molecules images are like advanced specific frequencies so we can use this
fact to try to identify the composition of astronomical objects from the light they use
areas the way can be particularly important using the studies of our collections where the boys can have very
interesting conversations for instance the curiosity rovers which
was landed uh recently on mars is carrying human knowledge came cam
and there is a tm cam was designed and tool to answer the questions related to merchandise that all depend on chemistry
the type of raw its uh chemical makeups and the crystalline structure within each of the substrates extra chemicals
examine our chemical composition processor for stars planet comets
intricillar media and scientific scientific will use the artificial satellite distributors etc and explore
how uh atoms molecules ions and free radicals interact outside the earth atmosphere
and contribute to our understanding of geological processes in other planets
us i recently mentioned about the kim cam which was used in the curiosity rovers uh
on mars and contribute to our understanding and examining monitors on other planets and
outreaches to understand the conditions under which life might form and
in this episode like how long about how scientists look participate atoms and molecules in space in which the ones
they have uh discovered so far like atoms and molecules are pretty much
everywhere uh from the iron heavy center of the earth to the hydrogen which
involves of the skins start nuclei and their attendant electrons
it makes sense that that astronomers will want to sort out what it of them wanted to make up with
astronomical objects and swim in the space between them but they cannot exist without grave hunk of star
and they must do the analysis remotely and as always in astronomy using only
light that that is suppressive leadership we can take this uh object in the lab and examine so we have to uh
think of the alternative luckily for astronomers elements and molecules when heated or excited or transit and
anything with discrete wavelengths of light uh the radiation is the atoms compounding
fingerprint uniquely identifying it whether it lives on earth or is it
in um german officials that is uh joseph von from
discovered that when we pass the sunlight to a prism
separating it into component color dark line appear across the spectrum not
contain marinade notice we measure the specific wavelength at which the line is appeared and the tricky things about the
spectral line is that this change based on how an atom is moving relative to uh
you and just as a side and become higher in speeds is a fire truck approaches
longer wavelength if an atom is going away from you it is squeezed to shorter
wavelength yeah it is coming toward you this effect uh is uh we know that it is
called some doppler 6 if our planets are starting a star back
and forth is its own orbit for example astronomer can see the spectral line
shift from stress to space as the star moves relatively to the telescope
if anything is clear it still can stream or hold up your space
is to normally investigate with every increasing spectroscopic sensitivity
they will be able to find out more about the molecules make of other solar systems already they have found exoplanet
atmosphere that contains carbon dioxide oxygen ozone water mixes and many more
so that you know i believe or even would even get extraterrestrial civilization at least
they are very green by looking for synthetic molecules like the sclerosis carbons with lsophone
the most visible uh the next use of this uh chemistry uh is in the most visible
area we can see that this travels is in construction of the process
for heat resistance
we are foreign the chemistry and astronomy likewise in other space biology medicals jewelry
um furthermore like uh studying over this all astronomy is
linked with everything we are using and for example from in biology uh you
can uh you can be dedicated with the equipment biological equipment psycho
x-ray and different kind of medium like the developed development of the
astronomy can result in the development of the equipment which are used in the field of virus in the field of
medical field and recently uh yesterday i got to know
about the cloud computing uh cloud computing is something i will
keep and stores information about medical personnel of our medical field
and we will be long-lasting and are very secure
and if it is in the development and i was very curious about knowing about that company what is that and i think uh
i have studied about and um i collected uh many more
resources about that so i was planning to study about more our external cloud
computing i found it's interesting how relative being related with ic and being related with astronomy or
i can also build it with everything so today i talk about the
chemistry so if i continue my study and i will be sharing with you
thank you thank you deepti thank you well deepti i wanted to
i've asked everyone else um on the program tonight uh
what blows your mind what is the most amazing thing to you
about your understanding of astronomy and the universe
okay almost the understanding of the universe yeah what just is so amazing to you
uh it's just annoying about ourselves or knowing something related to us
uh i often say this uh like uh it is said that we are made of starters yeah
and we are a part of startup so we are the life commons starters uh so it's obvious that we are the part of it and
we are by declaring direct immunity so i would like to say or
i like to point out that it's obvious to study of ourselves and uh
like over those it's a word talking about the mystery doesn't work
from interesting to of course while studying about astronomy about the universe is
interesting itself and some kind of history and some kind of
like we just knowledge oh this way that's something uh give us
energy to know about the universe and study about it
i i would agree with that that's that is um you know when when we think of uh
you know all the way from the iron in our blood to the calcium on our bones
uh to absolutely everything you know we are somehow um
reflections uh and energy you know intrinsically connected to the universe
so yes well that's that's great it's a great way to close uh the 103rd global star
party thank you deepti i'll bring on uh who else is on with me still adrian's here i think caesar's
somewhere in the background but um yep i decided to hang out for the end
okay well i want to thank everybody in the audience we had a great audience today um
and uh you know thank you uh to the audience as well for sharing your own uh
inspiration about you know what inspires you about astronomy and and the universe
itself and um we will be back uh probably next time
you see me i will be in yerevan at the starmus event uh hopefully introducing
uh some people that uh are presenting there and um
we will uh also be uh trying to put together a
global star party while i'm gone um uh in that country so we'll see how it all
works out um but until that time you guys keep looking up and uh
we'll see you at the next global star party good night good night
and here we go good night
