Transcript for part B: 

oh that's beautiful
we have more moons than i thought
yes i wish
[Music]
[Music]
hmm
hello kareem good to see you hey david hi everyone
hello
hi samantha hello nice to meet you all
except for cream yeah it's never nice to meet me i understand
it ropes me into so much stuff i don't do anything of the sort i just
give you ideas whether you choose to go with them or not that's up to you i can't say no to good ideas though
i can tell you those lots of people i email never reply but you just reply and so then you're stuck
i'm banking favors for the future [Laughter]
david how's everything in arizona oh everything's doing well as i was telling david and scotty wendy is doing
much much better excellent that's really good to hear and how are you doing karine
i'm recovering i'm recovering i've got uh not 100 of energy back but most of it uh
trying to get used to this clean-shaven-ish guy in front of me i still do a double take half the time the
so the stubble helps but uh it's very weird
wendy is getting used to her buzz cut yeah it's
you know the like when we have to do these changes it doesn't feel like it's in our control but we can make the best
of them uh my wife loves the clean shaven look so she's actually upset that i'm going with stubble she's waiting for
me to get rid of it so i said you know for mother's day it'll be gone yeah
my partner had to shave to wear like masks at work at covet i was like nope this is not working for me
he had a goatee i was like no he looked like his brother i didn't like it
what wendy also likes clean shaven hello
carol carol you're muted
that's better i guess terry can hear you hi david hello how are you how's it
going
hi karim and bob is here hi carol how's it going
good oh it's been amazing learning from bob the last uh few gsps it's been
incredible okay uh who is this is saying that
it's kareem from montreal from way up north okay hi kareem hey bob
i haven't been online but i've been watching you from afar i i took a few weeks off
okay well this is all pretty new for me i think this is my third third only third time on so
you know i came on once or twice and then just stayed so i hope you're just staying now because uh it's been fun
well yeah i hope so too you know if you do this more than a dozen times scotty will never let you go
again don't join the mafia yes
thanks for the warning no no samantha you you have to do this a dozen or so times
are you trying to take all my evenings away from me i'll talk to phil we're writing it into your contract
i already work like three to four days a week in the evening a week
i'm glad you specified that because three to four days a week was not sounding too impressive no no no i meant in the evening one of
them with the telescope i mean we're all astronomers but i have high school students up till 1am in the summer
exactly it's a remote telescope so it's it's and it's a remote telescope in a different time zone by three hours so
yeah it's in california and i'm in uh the eastern time zone so and see fun though look
right there you've got a topic for your next visit that's how it works
we'll talk later cream you brought it up not me
i'm losing my voice from this weekend i worked all weekend too so
and then what you'll what you'll find is pretty soon carol will rope you into being part of the astronomical league as well and then you know your weekends are
gone that's right we're always looking for good people what a nice invitation oh i'm not a good person
[Laughter] cream can verify that
i will say despite my best efforts she has yet to cry when i give her work to do so
no no you haven't made me oh wait did you you haven't made me cry yet you tried you tried to make me cry
in the new year you were gonna be the first one to make me cry in the new year didn't work not happening [Laughter]
and maxi i see he's here he did you did anybody see his pictures from the uh eclipse this weekend it was great
yeah i was in the show and people were i didn't realize there was an eclipse down south
in the south house here and then people i know i'm terrible i've been so focused on what's happening
up north if you ask maxie would become canada south for us
i'll come become ross canada itself we could have a canadian embassy in
maxie's backyard telescope
do you hear me we hear you how are you guys
good good great good to see you good to see you too kareem and everyone
we see everyone except scott this is this is the only problem with this setup is we miss seeing scott half the time
pay no attention to the man behind the curtain that's right that's right
i'm picturing the old wizard of oz musical where you like lift over the curtain and there's a little guy sitting there
controlling all the knobs that's right
great and powerful oz yes i'm gonna change that in my address book
that's from now on
carol for uh the rest of the astronomically live shall we introduce scott that way the great and powerful oz
i think that would be wonderful let's test it out in about a week from now [Laughter]
is that norm yep norm hughes is with us
yay yeah that's great
but now there's nobody competing with derek to be the first one with their name up when we go to break
yeah it's time to get started folks so here we go
on october 20th 2021 dozens of astronomers gathered near las vegas
they pointed their telescopes at the sky and waited for the moment that the light from a faraway star blinked out
it was an event so minuscule it would have been easy to miss yet the data gathered by scientists from
those few seconds helped contribute to the success of nasa's lucy mission
as the astronomers observed this star it appeared to blink out as asteroid uribetes passed in front of it urbidius
is one of seven trojan asteroids lucy will visit over the next 12 years the trojans are clustered in two swarms
that orbit the sun at the same distance as jupiter though they're as far away from jupiter as they are from the sun
these asteroids are remnants of the early solar system and by analyzing them up close
scientists can hone the theory of how the planets formed and ended up in their current locations
as uribides eclipsed the star a phenomenon scientists call an occultation took place whereby a shadow
the size of the asteroid passed over the region the best known example of an occultation is a solar eclipse which
occurs when the moon passes between the sun and earth blocking the sun from our view
leading up to the occultation astronomers predict the asteroid's shadow's path across earth and set up
dozens of telescopes along a line that's perpendicular to that path spread out under the asteroid's shadow
they count the seconds the starlight blinks out as the asteroid passes in front using the asteroid's known velocity it
is possible to calculate its width by observing multiple occultations of the same asteroid
scientists can catch different sides of the asteroid and combine their two-dimensional silhouette projections
into a three-dimensional shape model observing an occultation is one of the most reliable tools scientists have to
gather information about lucy's target asteroids and prepare for flybys of each of the missions targets
the team will continue to observe occultations until lucy's last flyby of patroclus in 2033

hello everyone this is scott roberts with explore scientific and uh the explore alliance and this is
number 92 of the global star party and um very pleased that you're here to watch this
um i have with me tonight some of the great astronomers from around the world and
we are going to start our night tonight of course with david levy
moving on to david eicher carol org from the president of the astronomical league is with us and many
more uh are with us as well and so i hope you really enjoy tonight's presentation
david levy uh starts off all of our global star parties uh he uh
you know characterizes each one uh uh based on a theme that we uh have
going and uh but he always ends it very eloquently with some poetry or reading
that's always inspiring and so uh david i'm going to turn this over to you but thank you for coming on to the 92nd
global star party we're getting close to 100 yes we are scott and thank you it's good
to be here when i first started in astronomy in montreal
isabel k williamson this was long before the days of kareem isabel k williamson suggested that i
start the lunar training program and that program involved looking at 300 craters of the moon with a telescope
identifying them and creating them in into my own map and i did that
i finished it by 1964. but as i was doing it one of the
creators that i noticed was one named rabbi levi and that was kind of interested me but
it wasn't until more recently that i found out more about gersonitis or rabbi levi ben gerson
who um who this crater is named for and it's actually very difficult to find
examples of his writing but i have found some and uh
there they really are he really presents a lot that is cause for thinking and for reflection
one of the things he said is about peace and i think those of us who are um
witnessing the uh fighting in ukraine right now the war in ukraine will agree with this a peace
that comes from fear and not from the heart is the opposite of peace
and the other one is something that comes right out of um
the 20 the 19th psalm about uh day of today yielded knowledge
night and night yieldeth wisdom and uh grusoni's rights do not lose
sight of wisdom and understanding but preserve them always
and on that note i give it back to you scott thank you thank you very much david thank you
yes uh we are of course all uh you know watching what's going on uh in
the ukraine every day and you know our prayers go out to the to the innocent people out there that are
being affected so thank you for bringing that to our attention david you know
so um uh we are uh uh we're now going to move to uh
uh to carol org carol is the president of the world's largest
federation of astronomy clubs the astronomical league they have over 300
member organizations they are very much friends with other
you know federations of clubs including the royal astronomical society of canada
they are getting ready to have their next astronomical league conference
which will be an in-person conference they've asked me to go along to help broadcast it to those of you who
cannot make it but it is a tremendous event and the
in-person aspect of these events are very important because you actually get to meet
people and make friends with people that you might not otherwise get get a chance
to do and i would say that those friendships are you know something that all of us that
are in the amateur astronomical community hold near near and dear
the um you know i can't i can't tell you how much i value all the friends that
i've made many of which are appearing here tonight on the 92nd global star party uh carol
kellorg is no exception and um so uh carol i'm gonna uh i'm gonna put
the spotlight on you thanks for coming on to the 92nd global star party
thank you scott for that wonderful introduction some of it might be true i don't know anyway
yeah but yes uh after three years after two years actually we're finally going to be able
to meet in person in albuquerque they have been very patient and they've
hung with us for three years in a row so this one's going to work
and david thank you for those uh wonderful words you uh gave us
to keep it all in perspective as we see the good in this world not just what's going on in the outer so thank you for
sharing that thanks okay let's uh let me share my screen and we need to
look at the questions
let me move this screen a little bit over here
okay
my apologies errol uh you have yeah close that window yeah
see okay
and they'll work just like that carol if you'd like okay let me go up here
and see if we can all right
okay we like to begin each meeting with the
precautions if we have door prizes later on they're awarded we want to make sure that the
proper precautions are used many of our amateur astronomers don't need these notifications but for anyone
new in the hobby we want to make sure they're not looking at the sun through one of the optics and
risk the uh of having some eye damage so we always like to put that up there
okay let's get into the answers from the last star party we had on april 19th
and some of these were dated for that specific night question number one for that event
uh they were talking about uh the next day after that event two weeks ago tomorrow morning 45 minutes before
sunrise what four bright planets can be found spread apart in a line like jewels
on a celestial necklace in order from east to southeastern horizon yes
yeah you're you're not sure you're not focused on the presentation window oh sure you can't see the uh so you might
want to unshare and then go back and share with your presentation window oh here we go yeah all right
yeah that's where i need to be you can see it now still not no no not there okay sorry about that it's all right
yeah you're i think you're focused just on the um yeah powerpoint i'll get there i've been on
three different computers the last three weeks so yes i'm an amateur at this also
let's see here okay
and
it might be easier if i unshare you or have you unshare and then go back and share
okay all right all right got that all right yep
okay
and
you see now let's see your computer's working
you see anything just yet we see questions it looks like question
three all right okay we're in the neighborhood sorry about that okay and the answer that first from
tomorrow night 45 minutes before sunrise what four bright planets can be found
spread apart in a line like jewels on a celestial necklace in order from the east to southeastern
heritage the answer to that one was c which was jupiter which was venus and
jupiter number two question
let's see the answer that first one was uh c which was jupiter venus
uranus no i'm sorry it was it was b jupiter venus mars and cider now we go to number
two a major planetary conjunction one that the public will be definitely interested
in knowing about occurs on the final morning of april it can be seen about 40 minutes in the southeast before sunrise
what two planets are involved that was venus and jupiter then the third one from that last one
the location of the galactic north pole on the celestial dome lies just east of
what well-known star cluster the answer was b coma
berenices and the correct answers from that one
were cameron gillis john williams andrew corkel
josh kovac i'm sorry andrew corkel let me get the other two
and then the answers for april for the grand prize winner which was
josh kovac and michael offer archer over ricker so now
let's get to the questions for tonight may 3rd for this
part for this part i think what i'm going to do is stop the sharing because you're still on your same slide so it'll
work out just fine if you just read the questions so okay that's what i'm going to do yeah and my wife has promised me a
new computer before we have another one we're gonna get this solved no problem
anyway okay all right so let me get to the
yeah let me okay question number uh one the james
webb space telescope's mid infrared instrument that's miri
finally reached the super cold temperature needed to operate as designed
the questions what are the approximate temperatures in kelvin
fahrenheit and celsius what are the approximate temperatures in
kelvin fahrenheit and celsius uh when they got the temperatures cold enough to
operate the instruments send the answers to secretary astro league dot org
that's number one question number two who is jessica
watkins who is jessica watkins
again send the answers to your secretary at astrolage.org
question number three how many moons does the planet mars have
how many moons does the planet mars have and again send those to secretary
astrolage.org and finally
our friend from canada was talking about some things we probably need to do in a couple of weeks at the astronaut
montreal live event the featured speaker for that will be dr
jessica novell who especially and the topic of her talk will be caravacanism buckle
uh cairo volcanism volcanism in the solar system
and that's defined as the eruption of water ice and dissolved volatiles
onto a body's surface pluto's moon sharon
shows evidence of that resurfacing but the discrepancies between the estimated
surface age determined from crater counts and the estimated time
of that start raised questions about sharon's history i'll be on there along with
chuck allen and terry mann from the league as well as scott roberts and david levy do regulars of course on this
and finally this summer talking about alcon the dates for that are july 28th
through 30th 2022 and to get registration information
go to the league website at astrolage.org and all the information is there
registrations are coming in very nicely and we'd love to have you in person uh
like we've said earlier this is the first time in three years we've been together for one of our national conventions we're looking forward
immensely and as scott was saying earlier two years from now we'll be teaming up with the with our neighbors
to the north and canada for the first ever joint convention with our two groups next year
we'll be meeting in baton rouge louisiana so with that i'll turn it back to you
scott thank you very much sorry for the interruptions no problem so that that would be a meeting in uh jointly with
the royal astronomical society of canada correct that's correct and i'm talking
off the top of my head but i believe we're doing it right before canada day the end of june in 2024
right before canada day right after that awesome totality that we'll all hopefully get to see with beautiful
clear weather throughout the path that's graham has guaranteed that the total eclipse will be visible before we
go so everything's good excellent excellent thank you carol thanks very much and
if you don't already belong to the astronomical league we do encourage you to join you can join as a member at
large and i have posted the um league website but it is astro
league.org so thanks again carol yeah we're 22 000 strong and we're always looking for
other good members so yes love to have you thank you thank you so much sure okay so um
that was wonderful and uh um we do appreciate the astronomically for
coming on to global star party each week to share their questions
and to challenge our viewers part of the
door prize assortment is going to be a couple of books we're going to talk about the
author of these books here a little bit later which is michael carroll but coming up next is you know i talked
about friends friends that you make at astronomy conventions and stuff like
that that actually go on to be real friends and certainly david eiker is one of those to
me but he's a friend to many many thousands of amateur
astronomers and people also interested in history this guy has so many facets to him uh
that his friend list uh well his contact list at least in his phone must be uh
almost bursting the uh the memory banks of of that uh that smartphone so
uh but i i'm very um uh pleased and honored to uh consider you know to be a
friend of david eicher and um yeah we hope that uh you attend some of the
events where he's there live uh one of those is going to be starmus and david
we'll talk about that uh in just a few minutes but let's bring him on uh to talk about uh his latest uh
insights into uh minerals of this planet earth
david thanks scott thanks for having me again it's a great joy to hang out with you
and with everyone here and and consider many of them friends um and uh i have some bad news though we
still have not worked through all 5 000 mineral species yeah we're still working on this so that's good news
hang in there with me we're getting you know much of the way done here but but at some point we'll go back to pure
astronomy here but this is planetary science and it's uh looking at how the universe likes to make
um planets if you will with these pure minerals and so i'm going to go through
a few more tonight and i'll share my screen and i will see if i can share a
slideshow and i'll see if i can start a slideshow um
and we'll see if we're in business and can you see a big red crystal yes
that is not what we're going to talk about tonight that's rhodochrosite that's just a
placeholder and tonight we're going to talk a little bit about magnesium and calcium minerals which are
fairly common minerals and we'll show a few examples of those those are pretty common
elements as as well but if first before we do that we'll talk a little bit about what
minerals are again as we always do thomas jefferson long ago said i believe in a divinely ordered universe
before his time even isaac newton one of our founders of modern science gave us
the quotation truth is ever to be found in this in the simplicity not in the
multiplicity and confusion of things the universe is ordered not by
supernatural design but by the principles of physics we don't need to
uh invent crazy things as richard dawkins likes to say we don't need to
magic things into existence but understand the way science works in our world and that's what brings things
together even minerals they demonstrate that because their atoms are assembled in precise ways by
electrochemical attractions that's what brings them together that are inherent properties of the atoms that make them
up and guide them into assembling into what mineralogists call a crystal lattice and that makes up these minerals
in specific ways and specific forms just as we as citizens of the universe who are made
of the stuff as we've talked about many times that are uh elements that are created in
in the explosions of massive stars or the collisions of massive stars or the uh
deaths of low-mass stars all of that stuff makes up the approximately seven octillion atoms in
each of our bodies as well so when we look at minerals we can look
not only at what makes up earth but uh we know that spectroscopy uh tells us that chemistry is uniform throughout the
universe of course and so we can imagine that many of these uh substances are
combining in similar ways on other planets throughout the milky way and and the at least 100 billion other galaxies
that exist in the universe so one of the things we'll look at tonight just for a little change of pace
is magnesium making up some minerals one of the many many common minerals
that that counts magnesium as a principal constituent is brucite that's magnesium
hydroxide it was named in 1824 by francois boudont in honor of archibald
bruce who was an early american physician and mineralogist and he was editor for many years of the american
mineralogical journal back in the day it comes in many many colors white light
greenish grayish bluish honey yellow brownish deep red brown it's a member not
surprisingly of the group of related minerals called the brucite group
and we can look at the crystallography of bruceite here just very quickly it's a
trigonal and uh contains magnesium oxygen and hydrogen atoms that magnesium
magnesium hydroxide there that you can see in the simple ball and stick
diagram so we'll look as always at a few examples of of things that show some
magnesium and some calcium minerals again these are kind of mixed up a little bit because these are kind of how
i photograph things in various shelves um in cases so they're not quite cleanly
sealed off but this is bruceite here which gives you in in many examples this
kind of uh sea foam blue-green color uh in the mineral this is from a famous mine in
the kalahari manganese field in south africa and you can see this kind of color that
you often get and i'll just kind of walk through some other related minerals that that are
largely magnesium or calcium are rich here
another one from the same area here in south africa it's called sterminite this
is calcium iron aluminum manganese sulfate tetrahydroxyborite so there you go you
know we're getting some some large numbers of elements involved here and those are the kind of uh
caramel colored crystals here that are on the the dark stuff is a really manganese rich um
sort of country rock if you will that the crystals are on here so this just gives you a an idea of the similar or
the same chemical elements uh just arranged differently with some companions and giving us
really really different looks even though there's some made up of fairly similar constituents here
how the universe likes to make planets so this is a mineral it's a fairly common one as well it's a magnesium
mineral called aimsite this is a chromium aimside and and the
chromium gives it a sort of a purplish color here but you can see there are little triangular crystals here this is
magnesium aluminum silicon from a fairly well-known region in russia
and uh quite a common magnesium mineral is spinel here which is also fairly
dense and it's sometimes even used for jewelry and so on as well it's in some
pieces of marble here and just to show you the same mineral being contaminated
with little uh what what mineralogists call chromophores that are some random
atoms that color the minerals uh differently even though they're uh the atoms are in small numbers relatively
giving spinel here from myanmar uh as cramer would say you know in the old day
or seinfeld that's burma to you and me um but that's magnesium aluminum oxide but
spinel from a different locality here in kenya that's almost identical uh is
bluish from a different contaminants here so also in a chunk of marble here
so little subtleties can change the look of minerals very dramatically even
though they're very similar constituents just as people over all the people and
most all of the life on earth is almost nearly identical in terms of
dna but we have a great range of different looks and differences as people
if we could only learn to get along because we're almost identical we can put that out to back to that mine
in russia there perhaps this is boricite which is magnesium borate chloride from a famous old time
mine in england here which gives you these sort of light green colored crystals
here a fairly common mineral this is a nice one too that's a mineral called clinical or and this is a
chromium clinic or it went by the name for many many years of camerite this is
magnesium aluminum silicate hydroxide from a famous region this is the only
really good region where you get this deep purple sort of a grape juice purple colored crystals of this mineral
in turkey ferrierite magnesium rich is are these
orange things that look like little things that might come alive in an early
episode of star trek when the you know props budget wasn't so large yet
this is a magnesium sodium potassium calcium aluminum silicate hydroxide
there's a three ring circus of elements there in this one with some other associated minerals from
a fairly uh well-mined region many years ago in italy in sardinia
this is a weird one it's a fairly common mineral as aggregates as little uh
clumps of of crystals called cortiorite however this is a gemmy variety of this
mineral that's called iolite it's nicknamed iolite this is magnesium iron aluminum silicate
and what's weird here especially from this region in madagascar is that you can cut it and slice it and polish it as
this cube has been polished and cut and that shows if you could turn it here
and look at it closely it's what mineralogists call and physicists call
pleiacroic that is it appears violet blue in color along one axis and golden
yellow along the other axis it's perpendicular so very odd optical properties of some minerals
exist here's another uh somewhat uncommon mineral magnesium mineral called called
botryogen it gets its orangey and yellow color from iron
mostly that's in it this is from my a well-known mine in argentina
this is a rare mineral called uh grand didierite that's another magnesium
mineral and and it's rare in this kind of a gemmy again seawater blue green
color another mineral from madagascar that's a fairly recent find of the last
decade or two this is an unusual mineral although it exists in nice crystals in many
specimens called credit this is from a domestic mine in nevada here it's a
calcium mineral that gives you these sort of deep violet crystals often
and this is a colorless not terribly exciting some mineral collectors think but one of these colorless minerals a
calcium mineral called hydroboracite uh which you can guess is borocite that's hydrated
and it's from a german location as well and gives you these nice needle-like or acicicular crystals
here's more borocite this is an unusual one from bolivia and those are the orangey crystals there that are
dipyramidal from a bolivian mine
this is schticktite a magnesium mineral from australia just again giving you a
range of color and and crystal types here from more or less the same elements all of these
lazulite is a very deep uh rich deep blue mineral the best specimens of it
come from the yukon in canada here and there are a couple of other associated
minerals here with it this is an indian mineral there's a
region in india that that contains a large number of hydrated minerals um
that that is a vast storehouse that has millions and millions of specimens the
interesting mineral here is calvin site here and the very common mineral is the
white still bite but the sky blue stuff or peacock blue stuff is called cavensite
it's another calcium silicate and here's yet another fairly common one that's often found in the
same indian location this one's from morocco however another calcium mineral
with these blocky cubic crystals called chabazite
and again that just shows you you know a great range of colors and types
of minerals of basically the same constituents but but arranged in different ways and forming of course
with different temperatures and pressures and chemical blends and so on give you this incredible range of
colors and shapes and as as scott said early on we're excited this year because
we're going to have the sixth starmust festivals for the sixth time uh we're going to be focusing on the theme of
mars and how the first martian missions that is mars iii from the the then soviet union and
mariner 9 the united states uh just a little over 50 years ago made it to mars
and and started to give us our modern view of the red planet we will have many many speakers they
were just about on the cusp of announcing a huge um array of additional speakers
there are some astronauts and some astrophysicists and the founder of starmus and the famous
jill tarter and even ordinary uh uh guys like me will be speaking
we also have some rock and roll there because we want to use our both halves of our brain both
hemispheres as we like to say the science and then having some fun and so there'll be some rock and roll with some
of our friends who are on the board like brian may and rick wakeman and peter gabriel and others and mr scott roberts
will be coming along with us and putting on a huge star party we think we'll have a thousand or more people at the star
party out of the 3 000 people at starman scott i think you're going to bring a dozen or more telescopes along yeah and
we're joining up with a local group of amateur astronomers there as well so that's going to be a lot of fun so
if you're thinking about coming to starmus maybe bring your if you can bring a grab-and-go telescope you can
join us and and that star party so it's actually pretty easy believe it or not to get to armenia if if you can get
to europe it's not much more than that to in terms of the travel logistics and
cost and the festival because we we think we'll have three to four thousand people there this year and there are
many students in armenia and we want to make it available to them physics students and others so it's going to be
really really cheap uh this time and and the armenian government believe it or not some governments are interested in
promoting a good society and making life uh better for everyone and believe it or
not the president of armenia who's helping to arrange starmus is a physicist
so we had a chemist who was the most senior politician in germany now we have a physicist who is the president of
armenia and he's helping to sponsor this and we're excited about it so if you can
get to over there into that part of the world in september you will have a fantastic
time with us and if not you're going to hear about all this stuff astronomy nobel prize winners astronauts
and i think there'll be some famous rock and roll people there giving a talk with me uh and playing their guitars as well and
you'll hear about this afterward if you can't join us in person yes that's great
well david thank you so much i'm really really looking forward to starmus and
um it's it's going to be absolutely fantastic as soon as i come back from starmus i
get ready for the arizona dark sky star party uh which is uh something that uh
we have hope to have david eicher speak there as well so uh we're gonna be
uh some exhausted uh astronomers i think but it's gonna be a lot of fun and we're
really looking forward to all of this if this is tuesday it must be arizona we'll be thinking or if it's saturday this
must be year event we'll be thinking one or the other oh yeah we'll be upside down with all that but
that's that's okay that's okay it's been a long time coming so yep
well great um thank you so much uh for coming on with us david and
we are going to uh uh reintroduce uh robert uh fugate who
has asked me to call him bob so bob i really appreciate you uh coming on to
global star party again this is your third time we were joking that uh if uh you know once you get past
a dozen of these things then you can actually never leave so
so but all right um i i certainly appreciate the
hospitality and the uh other talks i've i've really enjoyed
the the others other star parties i've been to and um
have uh actually looked up some old ones on youtube and find them all very
fascinating so thank you thank you i think this is a great service so thank you very much for doing it thank you
thanks for coming on and sharing your knowledge and passion with us thank you okay um
i'm going to try to get my screen going here and
so this might fit this this first location i'm showing here might fit right in with
david's talk this is the bisty wilderness in northwestern new mexico
and um i show it only because um i did um
i tried to to shoot a lunar eclipse there in 2015 and
it's a very unique kind of place it is a wilderness area you can only hike
to get to get wherever you're going it's very large [Music]
it's quite easy to get lost and there's no cell phone coverage
and so one needs a gps a really you know an actual gps device that um
that you can plot directions and and maybe even some maps
um so this is a kind of an ancient uh forest
area i guess it has lots of petrified uh trees large very large ones
and lots of uh erosion and hoodoos and just unbelievable kinds of rock
formations like i said it's very large and
it it is useful to go there with someone don't go out there by yourself if you do
go and it's quite the place to reflect
on the universe on your life on most anything you'd like
i went in 2015 with a friend here in albuquerque and
they have no facilities there's just a fence with a gate and a parking lot
and so you're all on your own and we we wanted to get to a particular
place that was several miles in and we wanted to be there at first light to get the correct light light on our
landscape so we started hiking before sunrise
and that's really scary it's very dark there but the sunrise was just gorgeous
and this area is very popular for astrophotography for doing uh nightscapes and so forth
and there have been a lot of really kind of famous shots this one was
an astronomy picture of the day in 2020 actually yeah
and um i think it also won some
astronomy photographer of the year award um martin zajac is the photographer and uh
so it's just uh an incredibly incredibly cool place that um
that you should take an opportunity to visit if you can so um when i was there in september of
2015 there was a lunar eclipse and of course we're talking about shadows
tonight and i wanted to share some of my clip shots this is a shot from the parking lot
actually you can see in the foreground here um the fence and the gate and a little sign
reminding you that this is wilderness and abide by the wilderness rules
um so this was the night before the full moon and i just wanted to get uh just kind of
capture what it looked like you know before it got really dark
and here's the night of the beginning of the eclipse it's just
it's just awesome to be in a place like this and witness um a total eclipse
um and i want to point out if you can see my cursor yeah i want to
i want to point out a little bit of coloration on the edge of the umbra there
and that's due to ozone in the atmosphere and so i want to show you later
the umbra and the ozone and just keep that in mind in 2018 i went to a place
northwest of albuquerque about 35 miles called cabozone peak
um this is a core of a extinct volcano uh it's similar to
um [Music] the one made famous in the movie
i can't remember what it's called now something tower devil's tower maybe but this one is just not quite as tall
um so this is a this is an image i made uh before the lunar eclipse
and it's illuminated by the full moon here you can see maybe um orion
to get you oriented and this was in january of 2018
and then when the moon got over and got into the earth's shadow we got this picture
and the cluster next to it here is the beehive cluster um
you know there seem to be a lot of eclipses around beehive and i tried to orient my location
so that as the moon set it would go right behind the peak here
and i was pretty successful i got this shot and this was almost at sunrise
so the lighting has changed a lot and you know there's a lot of pink in the sky and so forth
so that was uh one one thing that i i messed up on was
when the when the moon got fully eclipsed and it was dark
the coyotes started howling and it was quite the chorus i mean it
was unbelievable and i kicked myself now because i should have just turned on my phone and
recorded it um because it was really quite something they were
you know they were uh either upset about the fact that something had happened to the moon
or they were enjoying it maybe both and then uh last november we had this
partial um partial eclipse uh it was really close to the pleiades
and i shot this one in my backyard um and then in 2019
um i went down to magdalena now this is this is john briggs's place
and uh this uh mobile dome here is up on the hill behind his house
and um so i went down there hoping that um you know i would be able to witness a dark
sky when i as i drove down there were all these clouds around you can see the clouds and
actually in the in the left corner here you can see the moon try to put my
cursor over here on it it's barely barely visible in the clouds so i was
i was really kind of uh disappointed but as the evening went on
it got more and more clearer and um
and it and except for some very high thin cirrus which kind of was kind of cool because
it made the stars a bit bigger and and you really didn't see it
unless you took like you know a fairly long photograph but anyway this was my setup here um
it's an old um um
it's an old uh mount and i've
i haven't used it so long i've forgotten what it's called i'm sure you all recognize it it's a any
q6 uh mount and uh i had i had borrowed this
takahashi um epsilon 180 ed
which is a f 2.8 uh newtonian camera is on the other side i i had a
d850 mounted to it and um so and then i had my laptop here on the
card table and then i had a tripod with some other cameras
so i wanted to everybody of course understands this but i wanted to
um here's a here's a nasa graphic on the
shadows cast by the earth during a lunar eclipse and
the dark part is called the umbra and the other part of the shadow surrounding that is the penumbra
and so i wanted to try to capture some images to visualize that
and this is what i came up with wow so um what i did here was through that
telescope i took seven or eight stop hdr images
as the eclipse progressed so this is at the beginning and you can see the umbra start to come
in here and so then i had this series of images which i processed as
hdr i put them in photoshop in layers and i rotated them
so that the curves lined up so that you can visualize the umbra of the earth's shadow in this
picture and it gives you a feeling for how big the shadow is in comparison to the to
the size of the moon and then um at the at the
height of the total eclipse uh this is the actual
um orientation of the moon and the umbra at that time
and you'll notice it's a little brighter on this side than this side and i think that's maybe because it's closer to the
edge of the umbra you know rather than being it's it's rarely goes through the center
so um so it's rare that the that the uniform that the illumination on the moon is
uniform but the the bonus here is
uh this blue ring and the blue ring comes from
ozone in the upper atmosphere ozone the the peak concentration of ozone is
at about 35 kilometers above the surface of the earth
and it's of course not very dense but
it has a strong absorption for
wavelengths visible wavelengths longer than about 500 nanometers
the absorption in the red is several hundred times higher than it is in the blue
and so what happens is the blue light gets through you know in this from this layer
and the red does not and so that's why when you see pictures like this one on the
you know just before totality here you see a strong blue tent
and that's uh caused by the ozone so while i was while i was uh taking
these pictures um i was setting up another camera
um [Music] and with a wide-angle lens because i wanted to try my goal was also to try to
get you know a starry sky with uh with an eclipsed moon
and um so i got this shot wow um
and this is a composite uh it's actually you know a couple of a couple of uh
pictures put together you can see how the stars are sort of bloated here and that was because there
was some remnant of sub-visual cirrus at high altitude that kind of
softened the stars and enhanced their color so i thought it was kind of cool
but when i looked out and saw the moon the eclipsed moon just hanging there in the cosmos
it just really blew me away i mean it's just like three-dimensional yes and so i
so i work to try to get a photo of it and here's the the landscape that's just east of
magdalena there uh at john's location so um
that's kind of what i had this had to show about shadows that's beautiful
uh bob the image that you have of the that presentation that you have of the
uh earth uh earth shadows against the moon yes
how did you separate those exposures were you able to make lots of exposures and then just
pick one yeah i mean i took i took um you know i took exposures every
few minutes right as the as the uh the clips progressed i just took
more and more you know every you know i was actually on a cadence so that i tried to get
um get them with um some similarity right some progression and
but each time i took one of those pictures i took an hdr set so i i
you know i exposed for a lot of different times so that i would cover the
you know several stops that exist between the illuminated part of the moon and the shadowed part of the moon
and um you know there are it's like seven stops between an eclipsed moon and
you know one that's not eclipsed and so then i just processed each set of
those hdr images um and put them in layers on in photoshop
on a big canvas and then i just moved them around you know to well i
you know i looked up i found out how big the umbra was and i you know made a little graphic in
photoshop a circle and then i you know for each layer for each image i
just moved it into place and rotated it and lined it up with the circle so that
the shadow the circular part of the shadow lined up with the circle that i had on the graphic just a incredible
display i mean it becomes it's an astrophotograph that is also a visualization
right you know so that just conveys that one image of all of that just conveys so much information
and uh to be very honest it's the very first time i've ever seen it done so it's uh it's beautiful um and uh
inspiring and i think a bunch of people are going to try that okay well next to clips coming up so
i just wanted to add i just wanted to add that i really did enjoy the uh
different eclipses that you photographed over the years and the different appearance of the moon
and one of the interesting things that we're going to look forward to on the 15th
is the luminosity of the a fully eclipsed moon there's actually a scale
called the dungeon scale that you could use to determine the luminosity of the eclipse moon from l equals five where
it's a very bright coppery red it will equal zero where the moon just
almost disappears and we might be having an l two or one this time
for the simple reason that there we have had some major volcanic eruptions in the
last few in the last few months one in an undersea volcano near in the
near the hawaiian islands put a lot of dust into the earth's atmosphere and then one just recently
did the same thing and uh with with all that dust we might get a dark
eclipse this time the darkest one i've ever seen was december 30th 1963
was an l equals zero at mid totality i couldn't see anything where the moon was
housed amazing yeah thank you okay great thank you
great okay well thank you again um bob and i hope to have you on future global
star parties that i think you're you're raising uh the bar for each of us every time so i really appreciate it
okay i i do plan to i do plan to get out into the new mexico desert for this
eclipse so hopefully it'll be clear and hopefully i'll be able to operate my
equipment in a way that brings forth a new image great wonderful okay
all right so um uh and thanks again uh our next speaker is uh
samantha jewett um kareem jaffer professor kareem jaffer
from the royal astronomical society of the montreal center is going to introduce her um
and samantha is also
involved very involved in astronomy outreach with the royal astronomical society of canada so we're going to
learn a lot more about her i'm really happy she made time to be on this program very happy that karim introduced
her so karim i'll turn this over to you thanks scott um it's great to be back
and before i introduce samantha i actually wanted to take a few moments uh if that's okay
i wanted to share an in memoriam samantha and i are on the national
education public outreach committee and one of our members from the sudbury center in the north bay astronomy club
here in ontario canada linda puglia just passed away suddenly this past weekend
and we are heartbroken she was one of the first people actually met in uh in
outreach at uh the rasc back in the 2019 general assembly in toronto when david
was doing his biography talk linda had just brought the sudbury
center into the rasc and sudbury center joined us in may of 2019 she came to our
general assembly to represent them joined the education public outreach committee at the same time that i did
and we were just we became fast friends she was a girl guides leader for a long time
really runs uh and organizes a lot of their members and public outreach star parties in the national parks in ontario
killarney park over north bay area near the lake and it's just it's a big loss for us
nationally as well as especially for the sudbury in the north bay center so i thought a great way to memorialize her
for us is the way in which i remember her most fondly which is at our last
online ga she and i decided to do an entire comedy routine to start off the education and
public outreach center so i have a few jokes for everyone to help remember linda
so uh scott david i think this is right up your alley why does a moon rock taste better than an earth rock
oh it's a little bit meteor
[Laughter] do you know what the astronaut said after his first meal on the moon base
since the artemis is taking us back there i have no idea the food was good but the place lacked
just a little atmosphere this one is especially for david eicher
why should you never trust an adam
oh you got me they make up everything oh no
all right one more one last one how do you know when the moon is going
broke it's down to its last quarter
[Laughter] you see why she's going to be missed those were some of her favorite astro
jokes so i thought this is a good avenue to share them and uh that was good samantha and i have
both been privileged to work with linda and she's been working on developing a beginner's outreach certificate that
our public outreach members when we have an audience that just comes out for one night it gives them a chance to look for
a couple of things and get a little sticker or something on their way home to say that they've learned a little bit
about the night sky so that's the project that linda was working on last and hopefully that'll be available at
the rasc by the time the fall rolls around and we're hopefully really back in person in full
now samantha and i have been working on another whole set of projects that she's going to talk about with you
tonight she's our resc outreach coordinator our remote telescope guru
and whiz and just an all-around awesome astro us astronomer slash astrophysicist
in training uh she does have her degree already um but i'm gonna say in training
because she still has she still has to get out there with the telescope for us to see like you know her navigate the
night sky and show us that she's star hopping in all the wonderful fun that we talk about every tuesday night so
samantha tell us all about what the rasc is doing right now for the artemis mission outreach
thank you so much for that wonderful introduction cream and thank you for sharing those kind words about linda i
echo them completely she will really be missed um so as kareem said we have been working
on so let me just share my screen so you can see some lovely pictures in addition to my face
um sorry my screen's
don't want loading like share my screen it's just the lag time from the moon to here that's all it is
oh where are we i am so sorry i don't know why i'll share my whole screen okay here we go
um you see all of my windows i apologize uh so
there we go the big project we are working on is celebrating humanity's return to the moon so we have a number
of celebrations but before we dive into this i'm going to tell you what i even mean by humanity's return to the moon
um so why are we even celebrating well the csa the canadian space agency approached
us and said we want to get the public excited about something called
the artemis program now the artemis program that name sounds familiar uh greek god is the sister
program to apollo like artemis is the sister to apollo uh it took me too long to get that it was
embarrassingly long and now it makes so much sense however this is the next stage in deep
space exploration and lunar exploration but i see deep space exploration because it's going to lead to so much more
it's led by nasa but uh through the artemis accords there is a variety of space agencies across the
world as you can see all the symbols down below um i said the canadian space
agency is a part of it we are contributing um our knowledge in a lot of our robotics and this is just
all the space agencies have come together to agree on a way to peacefully
and collaboratively explore space and starting with artemis mission
so exciting thing this year it launches artemis one let's go the artemis mission
is in stages so artemis won they're testing on everything they have a brand new launcher they have a brand new
capsule called the orion capsule it's the size of a minivan designed for four astronauts so i don't know if i'd want
to live with three other people in a minivan for uh the time that they're up there but
kudos to the astronauts this is why i appreciate them and i'm glad they're going up there and not me um the artist
one is doing kind of a loop around the moon to make sure everything works and that is happening um they're hoping in
june this year uh now we all know how space travel goes it could be pushed back but it's only been pushed back by a
couple months or weeks recently so look to james love like it's getting it feels like it's actually getting close
artemis 2 is going to happen in i think right now is estimated 2024 but don't
quote me exactly on the dates because they change and this is the first crude test flight so it's going to take a similar do a
similar thing as the artemis 1 mission did it's not going to actually land on the moon but it's to fly around the moon
cool thing for canada is we're going to have an astronaut out there and this is the furthest we've gotten
because we weren't heavily involved we were not involved in the apollo missions and then finally artemis iii which uh is
hoping to be happening in the year or two after artemis ii will have the first person of color and the first woman to
step foot on the moon which is so exciting um this is just super exciting
with these three missions but on top of that we're not gonna like just go there and
come back like we did last time we're building a base there starting with building a space station about 1 6 the
size of the iss when i say we i mean humanity as a whole because i like to think of this all together working
towards this it's going to orbit the moon and it's going to be a base a waypoint for eventually if we do more
deep space travel the waypoint for the at the module i told you that takes the astronauts from earth it'll go dock to
here and then they'll use this point to go back and forth from the moon so what are they going to do on the moon
well a lot to experiment we are building a base camp or in my brain i like to think of it as a really decked out
tripped up camping site on the moon so no more just a flag we are having
experiments there will be rovers we are going to explore the south pole to look at liquid hydrogen oxygen and water um
and there's just collaboration from all over the world to do this this is this is like the iss
but further um and to also this gives us the opportunity as well to learn
about what we need to to do deep space travel with the iss we can just ship all
our food but we're gonna be farther away and if we go to the mars go to mars we are too far away to keep on shipping
supplies so we're going to do experiments of how to grow our own food on the moon and how to um use the
resources there so this is kind of not only to explore learn about the moon and earth and everything it's a stepping
point to um learning how to travel deeper in space so everybody's like why do we go
back to them we already did this well this is a place that's familiar quote-unquote familiar but
a place that gives us the challenges that we're going to have deeper in space so incredible
decade plus of stuff coming up i am so excited that i am getting to live to see this because
uh everybody knows i'm a little young to be alive during apollo the last apollo missions were 50 years ago this year so
twice my age um but it's just so cool for
to see us doing this again so i i said that is why we are
celebrating how are we celebrating well the rac or the rask is
doing several things first of all we want to educate people on how to view the moon and learn about the moon
themselves that's what we're all about amateur astronomy getting out there looking at the sky karim said i was an
astronomer in training because like really the only thing i can expertly look at is the moon but i learned so much just looking at the moon and i love
it this is my photo with my cell phone camera which is not as beautiful as bob's but i'm very
proud of it because it was one of my first times i took the telescope by myself so we have several resources online um
let me see if i can get to them so i will just show you very quickly
what we have here we have all about this artemis program if you want to look in deeper talk about
nasa there's online resources to learn about this and the moon in general we um
we also have indigenous knowledge that we are sharing that we've sharing from other um
indigenous educators we have a list of helpful books we also have a lit we have
done all of our uh webinars we put them in one place to show you how to view the moon walk through that tips and tricks
we have a whole um half an hour i think there's 10 or 12 up eight episodes that goes through how to
view all these beginner targets on the moon we have target lists so what even look at the moon and if you we also have
certificates so if you are our asc member and you complete our moon certificate you get a lovely pin
we tell you about use flaps and websites i even painstakingly made a map
with our target list for every single lunar day and every single view so if
you want to know what is on the moon that lunar day find your lunar day and those are the targets
you'll be able to see in telescopes or binoculars that's great work um
and we also have resources to learn how to sketch the moon because it makes you a better observer if you look and start
sketching um what you see you really start to notice more details and i found that while i was going well
was and and continue to go through our list of lunar targets we even have reference images here for you to test
um i will go into what this the sketching the move webinar is more about so
confined all that brass.ch moon resources all free you don't have to be an rasd member just check it out if you
want to learn more so on top of learning about the moon we want people to share their views of the moon we are
accepting submissions from anyone you can be can be a video it can be what you're you're sharing um
a 30 second video about what you the you're feeling about first seeing the moon a video of what you uh that
you've taken of a moon it can be pictures it can be drawings it can be anything we want to see what you see
when you look at the moon and you feel and that is at rastati sharing them sharing dash moon
so these are some submissions that have already come in we are using these we're sharing them on our social media as well
as um a webinar they'll get into this was done by an 11 year old it is amazing
um it's pastels gorgeous um and they submitted it i just i love this
photo that's amazing um sorry this is from one of our outreach
people i started talking to her about this and she said hey the moon was the thing that got me into um astronomy
i took these in high school with a film camera and developed them with my teacher and she said nobody really like
did i just took it with my camera up to the eyepiece and she still had these um
she didn't tell me how many years later but i thought these are really cool and then we also have just gorgeous
astrophotography um these are just three of many and we're still accepting submissions so if anybody has beautiful
views of the moon they want to share with us please do we also have we are launching again for
the second year in a row a specific a creativity program for youth ages 5-17 we're expanding the age
group this year called creation station um it's basically anything you can send digitally to us any uh that a youth can
send digitally to us so it can be short stories videos comics drawings um
multimedia things collages poems we are sharing on our website as well and we're
collecting them and it doesn't just have to be about the moon we do have a specific section for the moon but this is anything space related um
and kareem is one of uh the masterminds behind this as well you see he's got his hands and everything
um and these are two things we got last year um they are mixed media we have a poem with a wonderful drawing and we
also have a plaster scene and drawing of an astronaut
so another way we are selling the moon is as all of us amateur astronomers do is
have star parties we've had we've connected with rask centers all across canada they are both hosting online and
virtual star parties it's already gone underway through the month of april in the first 14 first 14 lunar days when
you could see them or the first days you could see the moon during the evening because we weren't going to hold the star party at 5 a.m unfortunately we're
lame like that um and they've been online and in person i want to share with you a couple of the
online stuff that you can go back and watch uh ras toronto had an excellent one they had a speaker that talked about
the artemis missions they shared live view of the moon they had reflections um from one of the rash toronto center's
daughters you can find that at risc toronto's youtube another one that scream and i were both
involved in uh we hosted the tina forget she's the
seti artist and residence director um and she's just an amazing artist she
has this whole series of woman impact which are creators named after woman uh this is one of her images from that but
she taught us in an hour session she only drew for half hour how to sketch a lunar crater
and you can go back and re-watch this great tips on what drawing materials to use how where to start and just to do it
and how it makes you a better observer we had some sketches from as you can see
prob um jessalyn is a very experienced artist
from and all the way to david lee who had never drawn a moon crater before and this is what he got out of it in a half
an hour destin is actually a youth she's uh 17.
oh my goodness that's really nice we have some talented people here like oh
my um so these are gorgeous things so if you just want to know the basics
10 out of 10 watch that webinar it's one of my favorite ones i've ever participated in um and been a host of
i i'm sorry all the other webinars i've been a part of um and as we all know international
astronomy day is coming up on may 7th so we've got to do a lot of stuff if you are located in canada i really encourage
you to look up your local resc center and see if they are doing anything i know a number of centers across canada
are doing things on the friday and saturday and most of these are in person um some of them are the first time these
spencer centers are doing things since uh covet restrictions lifted so great time to get out and view through a
telescope but if you can't we are hosting and this is for all our international folks too we are hosting
our shooting for the moon webinar which is a webinar just celebrating basically what i told you about but views of the
moon across um across canada because we are locating canada as well as just how the moon in
general and where we're going we've also connected with astrofest in montreal who is hosting canadian astronaut david st
jacques um for a talk and so we are they're doing it in french there and uh
the csa is um live streaming is french talk online as well but we are offering
an english pre um a pre-record version of that talk in english for the people who cannot join in on the uh talk at
astrofest in the planetary montreal followed by a live q a so we are going to tune directly into the planetarium um
montreal and there's going to be a mix of live and online questions so we're going to be gathering questions from our
audience um and slightly ahead of time for the people who've registered to ask questions then we are going to hop in
after all of that to a national live stream we have reflections from people who remember apollo and where they
their journey to doing the moon now we have i think oh it just it ballooned today um i think
six different centers from across canada showing us their live views and um
parties that are happening and just tuning in and we are going to share those that moon content i was talking to
you about and just talk about um artemis in general so if you i encourage you to
register it's via zoom we're going to live stream on youtube at 8 pm but the davis ajax section is only via zoom just
because of the technicalities of it so bit.ly shooting for the moon and if you want to learn more about
anything i've talked about it's all in one place rast.ca artemis parties um you
can always also uh conte go to ras.ca and go to contact page find us
find find myself i'm sure if you google me and rask i will come up and we hope you can join us and just are excited as
we are about this next stage in lunar exploration
thank you
scott you're still muted there we go i'm unmuted now
i thought i was going to sneeze and i did not want everybody to have their ears blown out if i did that but
apparently for some mysterious reason i didn't so anyhow um
samantha thank you so much for coming on to global star party um i know that uh
you know that you have a very very busy schedule and so if you can find any time in the future to uh come back on we
really would appreciate that so thank you thank you i'm sure kareem will find a
way to get me back on i'm sure he will okay all right
you enjoyed it thank you okay so um uh next up is uh molly
wakeling molly has been on lots of global star parties in the past she has a program called
astronomy's universe and we always enjoy her take on
on the science of what she images and her beautiful astrophotography
she dives into also explaining how she makes those astrophotographs um you know a
wealth of knowledge uh an extremely talented astrophotographer and the first winner
of the wilhelmina fleming astrophotography award by the astronomical league so uh it's great to
have you on again uh and uh thanks for joining us on the 92nd global star party thanks scott and glad
to be back again i've been away for a little while my schoolwork has got me very busy but uh
scott finally just texted me and said hey you should come back on and my cat is
also interested in uh being on on online tonight yes i think he just wants to be
fed as always um yeah so let me um i was going to share my screen but he's sitting right in
front of the button okay you need to go over here thank you
this is orion by the way name um
i put up a picture of uh one of my lunar eclipse
takes because i wanted to share it but i didn't focus my talk on it so i like this one i'm very happy with it
absolutely um beautiful thank you all right here we go
there we go okay um yeah so uh thanks scott for having me back again and um
taking the light and shadow in a little bit of a different direction i decided to talk
about the iris nebula so the iris nebula is
a combination reflection dark nebula region it's eliminated by a central star
and the dust reflects some of that light as opposed to an emission nebula like
the eagle nebula or the swan nebula or a lot of stuff in cygnus that absorbs
ultraviolet radiation and then re-emits it as as this deep red light instead
this dust is is reflecting the blue light from the central star and it glows
blue as opposed to to red or blue from oxygen and the dark nebula is made up of light
absorbing cold molecular dust which i'm going to have a slide on a little more on that later
so if you want to go observe or photograph the iris nebula it is up just off the edge of the
constellation cepheus or cepheus i've heard it pronounced both ways i'm not sure um which uh in
the good time to see it in a northern sky is actually not when it's oriented this way but when it's oriented upside
down uh when it's up high up above the north star so
over here this is the star on the on the edge of the w of cassiopeia to kind of
orient yourself there and so it's opposite cassiopeia on the opposite side of cepheus from there
um kind of halfway between the two bright stars of cepheus and um
a little ways off to the side so um yep that's where that's located
so some fast facts about the iris nebula even it's actually the nebula is it has
a higher uh is brighter magnitude than the act than the central star actually because of all the light that it's
reflecting over a larger area at magnitude 6.8 it's pretty bright
it's 300 light years away and about six light years across so quite large not as large as some
emission nebula like the rosette nebula which is like 150 light years across but
it's still that's a lot of gas and dust being lit up by one star and something that is six light years across
which is um depending on how you measure the width of the solar system at least 12 times the width of the
complete solar system and more if you just are counting from the sun to pluto
the molecular dust contains organic molecules and some of those organic
molecules are quite large when you don't really think about there being organic molecules floating out in space but
that's one of the constituents of of these dark nebula are some of these larger molecules that i'm
going to talk about a couple slides here and the blue glow in the center is so
that the star that's at the center of there is a hot young star so it's still
glowing very much in the blue part of the spectrum just like how a really hot flame from a propane stove is blue
and emitting tons of energy dumping that into the nebula
so i like to show what the objects i talk about look like in other wavelengths besides visible light
and there's not a whole lot of images that were that are done in other wavelengths of the iris nebula because
it's mostly optical and some infrared so i have a piece of software called aladdin that is
sort of like a sort of like planetarium software but um more for like framing targets and you
can also see it's got a whole database of every kind of data that has been taken on some
part of the sky everything from radio to gamma rays and lots of other information as well so
when i can't find pictures online i'll go to over to the aladdin software and load up some of the databases and see if
i can find an image in some of these wavelengths so the image here on the left is um i
couldn't find like a like a real um like a real radio wavelength image that wasn't
just huge pixels um so this is a more microwave almost
getting into into far infrared um yeah it looks funny just because this is
like a like a patchwork of data put together here the image on the right is far more interesting this is spitzer telescope
data in the infrared so um if you go back and look at
this is a monochrome image of it you can see how we can't see through part of the
dust cloud and infrared light allows you to pierce through some of those dust clouds and
see a lot more than you would be able to see otherwise and get some really interesting information out of that
i'm looking at the uv database this is the best one i could find there which is only a partially cut off picture
of of some overlapping fields of view in uh near ultraviolet so it's again
this is a hot young star so it's emitting a lot of blue light which means it's it's definitely emitting lots of ultraviolet as well so it's really
bright in that ultraviolet channel then over on the x-ray side of the house from xmm
newton pretty much you can just see some of the star sources that are in there these are probably newborn stars that
are being formed in that nebula
all right so uh digging into a little bit of science a good thing to talk about with the iris nebula is molecular
dust clouds so a lot of so nebula like um
like the dark parts of the trifid nebula and a lot of these dark nebula you can
see in taurus and intermixed in places like cygnus
um it's all made up of what's called a molecular dust and a lot of that is is
actually molecular hydrogen which i have a picture for down in the lower right corner it's two hydrogen atoms that are
that are bonded uh and they're sharing electrons it's actually different from like the
covalent and ionic bonds that you learned about it is a specific hydrogen bond um that makes it very stable and
very symmetric you also find a lot of carbon monoxide which is useful for helping us detect
where the hydrogen is because molecular hydrogen's really hard to detect but wherever there's molecular hydrogen
there's also carbon monoxide so we can look for where the hydrogen is by looking at the
carbon monoxide which does emit light um i think it emits some infrared light i
think it emits some radio light as well and on the heavy on the much larger organic
molecule side of the house the heaviest organic or i guess i should say the largest organic molecule that has
been observed is something called benzonitrile which have the chemical formula here
carbons hydrogens and nitrogens a lot of organic stuff there and other aromatics
which is uh types of organic molecules that i think aromatics are the ones that form kind of
ring structures if i recall it's been a while since i had chemistry um so yeah lots lots more than just um
than hydrogen there's a lot of organic molecules up in these dark molecular clouds too which is really cool
these clouds are very cold they uh they're not absorbing and then re-emitting
ultraviolet light because a lot of these molecules they're emitting energy from vibration and rotational states which
are much lower energy than something like um an excited hydrogen atom
and or um yeah and so they tend to be about 10 kelvin which if
you don't speak kelvin and speak fahrenheit is negative 441 degrees fahrenheit it's just a few
degrees above absolute zero and in celsius that's negative 263.
the particle density of these molecular clouds basically how many grains of dust how many uh well really
how many of these molecules it can be a hundred particles per centimeter cubed or more which
can sound like a lot but that's still like a pretty healthy vacuum but um it's
it's it's enough of a concentration that the reason we conceived a lot of dark nibble is because it's blocking out the light from the stars behind it
molecular clouds are where new stars are born that's that molecular hydrogen eventually through gravity starts to
coalesce into a star and so our star was born in a nebula
like the iris number and as i mentioned earlier they don't they don't emit optical light but
they do emit down in like the radio microwave kind of millimeter area due to
the molecules vibrating and rotating in these specific energy states that when
they change will release some energy the picture on the bottom is the carbon monoxide map of the milky way kind of
showing where these molecular clouds are located and yeah they're all over the place
this picture here is a picture i took of the snake nebula when i was at the texas star party which is
this guy here got some really cool shape and i also kind of see like a bowl here
so that's a lot of fun yep so if you want to observe um oh i
forgot to change this title aside observing the iris nebula as opposed to the snark manual in
general this is from my last talk um so a good time of year to observe the iris nebula is uh if you don't unless
you want to be up early in the morning june to december is a good time when you can catch it before midnight
up in the northern sky so i don't i i'm not sure if it's at a low enough declination for some of our
southerly observers to be able to see it may be pretty low on the horizon for them at certain times of the year if
it's above the horizon at all but for the northern folks it's it's all it's actually circumpolar for most of us
so um yeah there's always a time to go to go check it out the star and the reflection part of it
are relatively bright and see you should be able to see that from more light polluted locations i
haven't actually visually observed the iris myself i'm kind of making some some guesses based on other types of similar
nebula but if you want to be able to see the dark nebula against the background of
stars you're really best doing that out at a dark sky site where you can actually see those background stars and
then see them being blocked by this dark nebula it's um it's not particularly small but it's not very large either it's about 18
by 18 arc minutes for kind of that main portion of it so good to look at in longer focal length
scopes like dobsonians but you could also look at it with refractors it um
still still a pretty decent size photographically you can do it in some light pollution in fact i'm i'm
following a thread on the um uh i think it's on the zwo forum on on facebook about somebody
trying to image i think it was this nebula trying to figure out how much dust they'd be able to pull off on the background from the city something i
haven't had much luck with but um it's so it is better photographed out in dark skies where you
can see again just like in visual more of those stars in the background and be able to actually see the dust better
against that background of stars uh larger field of view you can catch a lot more of the dust because there's
there's dark dust everywhere around this area it's not just concentrated around the star
so there's lots of stuff to be caught in the background um but you can get lots of detail on the core with um
uh yeah with smaller fields of view so with longer telescopes
i do want to note that if you are a narrow band imager who likes to use a lot of narrowband filters imaging from
the city even though there's a lot of blue light here this is not oxygen blue light this is reflection blue light so
there is pretty much no narrowband light here so you want to do broadband so your
red green blue filters or using a one shot color camera without a narrow band filter
and of course i have to show off my favorite picture of it and this is actually one of my one of my top 10 favorite pictures
this was done out at a dark sky site back when i lived in california and this was done with my takahashi
refractor which is 530 millimeters of focal length so it's actually a really nice target for shorter focal length and
it's actually make a really cool target even for for camera lenses um there's so much dust going on here in the
background um this was about a little it's like a five hours 20 minutes of exposure time
so when you're out under dark skies you can get away with much shorter exposures because you just get so much light coming and it's not being overridden
by the light pollution and yeah so this was done in a bordeal three and a half sky and i'm very pleased with it and anytime i can get
color out of the dust getting this this nice brown and being able to see kind of different
color gradations i'm happy and real happy with how this came out so yeah that's what i got
that's all you got that's pretty amazing any questions from the audience or any
questions on youtube uh people are saying beautiful images uh dan said the snake looks like the design
from the teox head in stargate um
so i so i have a question yeah uh i'm image from my backyard in
albuquerque which is pretty bright and um i have like 20 hours on the iris
but i don't see much color in the dust and i've always worried about the color of the dust
you know is it mine is like um i don't know i could show it i guess but
it's it's just kind of gray yeah so when i've tried to image
anything with dark nebula from any kind of light pollution even from portal 5 i've struggled to get any color out of
the dust um and i on the on the facebook forum that i was reading i made this point on there but
then people made a counterpoint showing images that they've done from portal 6 and portal 7 where they actually got color in the dust by doing 20 or hour
plus exposures so i don't know if i'm just not good enough for processing yet or what but uh i've
always struggled to to do dark nebulae from from the city um but i was 20 hours you may be able to
eke some out you may have to go and play with the color a little more with with my iris nebula image from a dark sky
site i didn't have to work hardly at all to get that color to pop out um because
i didn't i wasn't fighting the background but some people showed that it can be done from the city so um
let me while i've got you and you're the expert let me try sharing my screen sure
and you can look at it
oh yeah yeah that's actually quite nice um
very nice but you know it's doesn't and and i i asked some of the local
astronomy club guys you know because they seem to get more color um
but um yeah i i don't know
yeah i mean you did you did you did get quite a lot of dust there um
yeah i think i think maybe your best bet would even be to um i don't know how
exactly to isolate the dark nebula but to mess with the color temperature of the image okay
and uh maybe maybe mask out the stars in the core when you do your color temperature change so that those stay
accurate but you may be able to redden the um the dust a bit by um
so the dust really ought to you know have a more yellowish brown color you think you know i've been asking myself
that question because i i mine came out that way i've seen a lot of other people's come out with this brown red
color i don't actually know how accurate that is i wouldn't expect the dust to have color
but um yeah i well it does have some red in it actually there
the dust that is um near stars there is some hydrogen emission going on
from hydrogen atoms that are not bonded to molecules most of the hydrogen is going to be
bonded but there is some hydrogen emission that will go on if when it's being energized by a star so yeah i
guess there is some some red in there from that but i think having it be gray is is also
acceptable from an accuracy standpoint okay i'll i'll try to do some more work
on it that's a nice image though you got a lot more dust than i've been able to so awesome [Laughter]
great all right well thank you very much molly i hope to uh see you again
uh probably not on the next global star party because i know how busy you are yeah of course you're always welcome uh
and uh thanks for an amazing presentation thank you thanks for having me okay all right so um
up next is uh uh will be uh dan higgins and pete uh from
astroworld tv who have popular programs on youtube
uh but they are uh i've been on their program before they're fantastic
and they really get people uh take them to the next level in their astrophotography uh through their
presentations through their insight and through working through all the little problems that uh can attack
astrophotographers as they learn their craft so uh dan uh thank you for coming on let me
get both of you guys on the dan and pete show
there we go and let's add on pete myers here we go there you go
there we are you guys have the stage i got a black can you see me because i have a black screen i'm sorry yes we can
we can see you you are okay cool how's it going thank you uh thank you scott for those those kind words i mean
we really try and keep it light on uh astroworld as as you know as you know um
we have a bunch of people that constantly just come back and a lot of people that are in your audience now um
but um i i gotta tell you i gotta speaking of the mistakes that we make
and and the i you know dark nebula as molly was talking about you know i i i i got the big mistake and i'll premise
this right if you watch the show you know i love to make fun of myself so so i may as well and um so uh one of the other co-hosts
eric was um imaging the dark shark nebula and i said you know what
let me give it a shot i've never done dark nebulae before let me give it a shot now prior projects before all i've done
really is narrowband i'm an abortal eight plus guy on long island it's pretty pretty horrible and uh
so i said i set up my sequence and i done ready go to bed let it run all
night let me see what i get in the morning in the morning i go in the morning i open up a picture i got nothing
what i forgot was to switch my sequence from narrow band to broadband so i got eight hours of the dark shark
in h alpha so so so i got nothing so um i thought that was kind of funny
uh peter you're there yeah i'm here all right good good yeah so pete is uh one of the
members of astroworld 2 and he is with me tonight um
you know pete why don't you want to talk a little bit about uh what we do well it's kind of interesting is is that
basically it's really just a very informative um kind of giggles the last very very intuitive we
we definitely have reached out to a lot of guests including scott you've been on as well as uh we've got a multitude of
guests from bob dylan a lot of fun and it's interesting is that typically we'll have anywhere from what between 50
and 60 viewer members on and the nice thing about what we've got is is we've really started to kind of take this to
the next level it's the point now where people are really starting to tune into the astral world
show we've gotten a lot of good feedback we've gotten a lot of good
gifts in drawings and i think this whole asterworld is a testament to the detail
that dan has put into into making this you know it's kind of like the hardest thing is getting it started
once the inertia takes over it kind of just perpetuates itself but you know kudos to dan for initially starting this
uh this astroworld uh show and it's really just taken off the year lately
yeah and it's and it's been really really it's it's been a lot of fun and one of the things that we do and if i
don't know if i could share my screen i think i can let me just uh share let's see yeah i could just do it
right on my screen so so one of the things that we do every week um now that we got it all sorted is a picture of the
week and it's not it's not a picture of the week based on the aesthetics of the picture it's
partially because of that but it's all based on the voting of their peers this
is not this is not something that we take in the five of us or the six of us look at it and we pixel people
no this is all about the picture and and how the peers look
at it so we throw it online we do a we do a voting and we announce the picture of the week every week and if i could
show a little bit of of some of the pictures that we have uh let me see if this pops up um
and can you see that okay so so this is one of the pictures uh that
one picture of the week from andrus um i can't pronounce the last name he is uh
from europe uh he's one of our members and then we got um mark ellis who had the veil nebula
this was the most recent winner from uh ro ophiuchus this is from jason trevino who
who won the picture of the week that week and we have a bunch of pictures that have won across the past couple of months and
what we're doing now is we're taking this and at the end of
the year what we're going to be doing is um making an astroworld calendar that
goes out to the membership with all the pictures of the month because we'll be doing a picture of the month as well so i think that's going to be kind of cool
yeah the nice thing is is that you know and as i said once again this is a testament to dan is is that we do
two shows a week it's on wednesdays and fridays typically the wednesday show will start at 6 00 p.m eastern standard
time and then the friday night show is at five um eastern standard time so typically
i'm just finishing work and dan's already had a couple hours playing catch-up but typically the hours
on the show dan where they go probably between maybe two to three hours you know yeah hours depending you know
if you know if we stay on target too but we usually don't we kind of the the the the
comments in the peanut gallery and the chat boxes kind of throw us uh yeah it's off the loop and sometimes we throw
ourselves off and uh you know we call that off the rails and we do we do that every once in a while
just to get an idea of some of the guests we've had on we've had charles bracken who is the author of the deep sky imaging primer and charlie
absolutely just had a blast and he truly wants to come back a second time we've had dr christian sassy who is
general manager of i telescopes bob denny who is actually going to be getting an award at the aic show for
what he's doing on alpaca he actually had a ball on the show i mean it really is just a very informative show and as i
said we've got a lot of guests lined up we've got people that truly just want to step up and say hey i've heard about the
show how do i get on it so yeah and let's not forget all the astrophotographers out there uh sean
nielsen uh doc ron brett breacher juan keller
pete pruell adam block and and molly uh you're next
by the way i'm going to be calling you up because you're going to be next so so um you know so so we got we have we have
a huge amount of here doug strobel t.j conley simon lewis i mean we've had a bunch of people on the show so i mean
it's been a lot of fun you know it's such a small community this astro photography and and it's it's
interesting is is that when i look back at when i started scott you and i shared this last time we were on the show and
how you got started we really didn't have this kind of a forum to be able to tap into and get information i mean
literally we had to go out there and oh yeah it was hard and so you know i i think that now with
the technology with the cameras the fast optic scopes this really is the golden age right now for people that want to
take pretty pictures let alone for scientific and citizen science i mean we really are experiencing either way that
you want to go i mean it's it's all right there with the yeah and made all the better
because of the kind of community that amateur astronomy is it's such a sharing
giving community you know if you want to go from point a to point b as quickly as
possible uh there's just no better no better community to be involved with
and then you enhance that with shows like yours okay or being able to do something like global star party where
you know people around the world can connect um i i think it's awesome you know
you know i was thinking dan it's a shame that you couldn't come out to aic this year because it's going to be on a friday saturday it would have been the
perfect time to do the friday show at aic i know walk around but you know it's not to say that in two years there'll be
another aic so we have to plan that yeah absolutely and you know i'll be doing a
live portion of the show when i'm at cherry springs come uh a a month from
today i think this is the weekend so uh you know that's i'm so i am so excited
to go to church it's been three years i'm so excited to finally go to a dark sky spot that's under you know
portal eight you know you know i i might be able to do some one-shot color who knows i don't
know that's true maybe but it's it's a lot of fun uh we got the
members are and and the people that come week after week and day of the day on the show are really what what makes the
show and it i got you know it wouldn't survive without without everybody
showing up and uh i gotta show thank you to all of our people that that
support us so and if you don't know anything about us you can go to
www.astroworldweb.com you can look at all the pictures of the week winners you can look at all the guests we got coming
up uh i think tomorrow right tomorrow yeah we have um um richard wright from
starstone software tomorrow night um so that that's coming up then we got eric coles coming up on the 13th from the
astra imaging channel so he's going to be coming on um it's going to be a lot of fun we got a lot of people coming up
so fantastic that's great well um
guys thank you for coming on uh we have we do have just a few minutes left here
yeah absolutely yeah anything else that you'd like to uh uh discuss before we go to our ten minute break here no just
just come to the website check us out check us out tomorrow night um and we'll be there every wednesday
and friday night wednesdays at 9 eastern and fridays at 8 eastern some of the hardest working guys in astrophotography
are right here so that's awesome
okay well that's great uh i want to take uh just a couple of minutes here to um
uh thank uh you know all the people that have been on this first segment
we had david levy you know carol orange from the astronomical
league david eicher you know editor in chief of astronomy magazine talking
about minerals and crystals of uh magnesium and calcium uh
just uh you know his his collection is just so intriguing intriguing uh bob fugate uh
showing just just an astounding images of of uh the uh lunar eclipses and uh i
loved the image uh uh well i love actually i loved all the images but one
that's now sticking in my mind beyond the one that showed all of earth's shadow you know with the with the circle
of moon uh images there is uh the one it looked like the moon was just like rolling off the the bluff you know so
it was just uh i kept imagining what that might look like hung up in my house you know like a
giant uh 40 by 60 inch metallic printer that'd be awesome
really beautiful so uh samantha jewett uh who is um uh you
know astronomy outreach uh assistant at the royal astronomical society of canada
very cool molly wakeling with astronomers universe you know we all love that it's great um
of course dan higgins and peter myers
coming up next will be michael carroll a space artist and science fiction writer author
he has uh uh he has um provided a coup actually more than a
couple of books we're going to um we're going to uh give away we're
going to uh these two books here that have uh you know there's signed editions of
uh two of his science fiction books here plato's labyrinth and living among
uh giants and uh so hopefully you guys are entering into the
astronomical leagues contests and uh you know you'll be offered
to select one of those books if you so choose if you win um
up after michael will be carrie or karina l'etelier
she is in chile she also does amazing nightscape
astrophotography you're going to want to watch that marcelo souza down in brazil will be
joining us uh uh later on tonight uh and uh norm hughes
uh joins us he's i think he's in the background here been watching on as we've been uh running this program cesar
brollo uh with caesar's south sky universe maxi fellaris if he's still not freezing
to death will be on with us and then of course adrian bradley with his beautiful nightscape so
so we've got more to share and we really appreciate that you have
joined us and are watching on the global star party our 92nd edition
so let's go to break and we'll come back in about 10 minutes
[Music]
well hello everybody this is scott roberts at to explore scientific in the explore alliance and you've been
watching the 92nd global star party uh we're now into our second part of the
global star party and up next is author and space artist illustrator
michael carroll and michael has as i mentioned earlier in our program
michael has uh donated a couple of books here actually there's a couple more that we'll also be
uh using to give away uh for some of the um for the door prizes that the
astronomical league coordinates but these books are beautiful and
you know i would have read them myself except that i just didn't want to get my fingers too
much all over them uh you know start underlining them as as i do with books but you'll see that they are
beautifully uh signed and anyways really happy to have michael
carroll join us uh and um let me uh bring you on michael
there you are there you are perfect shirt as well you got your moon shirt on you got your moon is that the moon
behind you as well that is a moon that's gaining me
all right well wonderful well you said you'd take five minutes to talk about uh
your your artwork your books uh please take a little bit more than that because we're really happy to have you here well
thanks it's uh it's great to be here let me share my screen
and i will [Music]
see if we can get this to go okay
so um i'll just uh give you guys a few uh comments about these books but um in doing so we can
talk about some interesting things about the the cosmos in general
um living among giants is is really a non-fiction book about how we are
going to explore and ultimately settle the outer solar system
we've been looking at mars a lot lately throughout my career mars has always
been human exploration of mars has always been 20 years away but with things like artemis and some
other breakthrough technologies i think that it's really possible that mars is going
to be happening in manned spacecraft exploration
soon and that means that we need to take a look even further out the outer solar
system is full of resources uh natural resources for us to
use and um utilize as we explore further and
the the question may uh cross your minds is it even realistic to talk about
travel to the outer solar system with humans at this point it took cassini i think seven years to
get to saturn that's way too long for people to go sitting around twiddling their thumbs
and watching dvds but look at these um notice these numbers
at the turn of the last century in the late 1800s early 1900s
the average family in europe or uh or the us
uh ran on essentially two or three horsepower that's how many horses people
owned on average um half a century later we had aircraft
that ran on a thousand horsepower half a century after that coming up to
about now we have um airbus 320s and boeing 737s
that operate on almost um a hundred times that they're equivalent
to the combined armies of genghis khan
in an aircraft and these things take off 737s take off
every two seconds around the world so there's a lot of advances in
transportation it is reasonable with this um curve to think that
in half a century we may have ways of getting out there there are
some cool creative propulsion systems that have are being studied and so
we cast our eyes out to the outer system of course you can't uh land on a gas or
ice giant a big balls of atmosphere with very dense cores but
we can if we want to hang around out there deploy giant balloons and even build balloon cities
uh science stations to float among the clouds of these um gas and ice giants
what's really fun to think about though and a little bit more practical is exploring the satellites around them the
natural moons um the problem with the moons of jupiter is radiation you can
see that on io you get a deadly dose of radiation in a few
minutes on europa you get it in eight hours ganymede and callisto are a little
better targets but it sure would be fun to explore io wouldn't it be great to
run across all those volcanic flows and look up the plumes well there are places
that we could go that are sheltered from that uh radiation pouring from jupiter and they
are lava tubes a lot of the eruption sites on io are attached to lava tubes
and you can go down there and there's not much energy coming through so you can imagine
hanging out there the problem with a lava tube of course is that sometimes they refill
and that would not be good europa next one out the ocean moon
we would love to go there as well and it's a little bit easier and of course it's got a 100 kilometer deep ocean who
knows what's down there to explore in the future callisto is one of my
favorites it's got these ice towers uh imagine being a tourist and looking
up at these great pillars of ice ron miller shows us
a view of tourists on enceladus out at saturn of course we'll have
tourists eventually at titan where you can the the gravity is one eighth what it is
here it's less than the moon and uh the air is so dense you could actually
fly under your own human power and you can also go sailing
or take a boat out a submarine maybe surfing so
in the future uh traveling to a world like for example saturn might be a lot like our cruise
ships in the aegean sea or in the caribbean where you have uh
day trips to various different islands and then you go back to the mother ship
to move on so one day we'll have tourists i think standing at the shores
of these great methane seas on titan or the deserts of pluto
living among giants talks about the practical ways that we will use to get out to those
places and i know we have some physicists with us i know
karima karimen's background and so the other book plato's
labyrinth is is uh especially for for that kind of
discipline it talks about quantum physics of course we uh who look at the sky are interested in
the uh where it all came from the universe how
big it is how old it is the planck satellites has given us an incredibly detailed view this was from wilkinson
uh this overlay now is from planck some astrophysicists uh quantum
physicists believe that there are bruises in the universe where other
universes are bumping up against us tying into the multiverse
uh scenario james webb telescope of course is going to help us to
lock down not only the size of the universe but its age so
um plato's labyrinth just talks a lot about uh not only quantum physics but its fallout
as it were here's a guy talking to himself and from the future you left the toaster on
[Laughter] we also touch on
waterhouse hawkins who was a the world's first dinosaur sculptor he
was commissioned after he did a series of dinosaurs in england he was commissioned in 1870 or
so to do some for central park but because of some politics his dinosaur
statues were destroyed before the public could see them buried in central park
and to this day no one knows where they are but people are still searching for them so
waterhouse haka is a very colorful person that that novel visits and
it also deals with atlantis that great um continent that plato talked about
many of the characteristics that plato mentioned for atlantis
are actually found in the greek island of santorini was it may have been a
historical description of santorini uh at its eruption 1600 bc
or so uh this is what it looks like today uh with ten times exaggeration
vertically but there are all kinds of guesses as to what it was like back when it was thera
the hub of the great minwan empire so it's fun to
take science and turn it into a novel form that's
what plato's labyrinth does and other books in the series by springer called
science and fiction a bunch of novels that have a section at the back for the
uh the science behind the story so hopefully those will be enjoyable to you
guys wonderful wonderful that's great so uh michael how many
books have you written um i'm working on number 33
[Music] it's a book comparing different stages of the earth
developmentally to other planets so
wonderful see if i can stop sharing here i've lost my cursor
almost got it uh
all right here i can stop you're sharing it's easy for me can you great i will my cursor no problem
i like the little like drop and you know some some others
that's great so michael how how did you get fascinated
by i mean i i would think anybody would be fascinated by the universe but what
was your tipping point what what drove you into a lifelong uh journey into uh doing all this
well aerospace kind of runs through the veins of my family my grandfather was a
major general in the air force and kind of in charge of experimental
aircraft at the end of world war ii my dad was an aerospace engineer
and um one of my earliest memories is going out back uh in a a nice
pristine colorado evening with him and he we were looking up at the stars
as they'd been plastered across the sky for eons except for one of them one of
them was moving and uh he pointed up at that one and said that is echo one it's a big balloon
that they bounce radio signals off of and i said why do they call it echo one
and he said well because there will be more and of course he was right
amazing amazing well you you have uh you've given us a great evening here
with uh your beautiful artwork your illustrations and uh you know some lucky winner of
your books will be really diving into them so i hope you come back very soon because we're gonna be giving
away uh two more books uh and i'm trying to read one of the lords
of the ice moons and i cannot see the other one right here but uh i think the other one's drifting
on alien winds which is about the weather i think you're right weather on other worlds so
yeah wonderful well thanks scott wonderful thank you so much well it's been a great evening i will
hang around for for more great discussions yeah wonderful that's great
okay so our next speaker is uh carina lately
did i pronounce that right karina yeah perfectly
i think your volume is a little low uh can you hear me now perfect right now
perfect okay yeah yeah so karina uh lives in uh chile
where where is it that you live uh are you in uh la serena or where where are
you right now i'm in santiago the capital city but i live in temuko in the
southern part of chile and you do wonderful photography and astrophotography
and so you know i imagine you're going to treat us to some of this tonight but
tell us a little bit more about yourself okay well my name is karina i like the
constellation it was just a coincidence but a pretty good one
i have 35 years old and well i'm from chile i'm an industrial
engineer actually i studied i also have a master's degree in logistics and
a graduate certificate from mit in logistics also but i quit my job around
four years ago to dedicate myself 24 7 to astronomy popularization and also to
astrophotography landscape astrophotography wow that's very inspiring uh and and a brave leap
uh for someone to uh to take you know because i mean you have the the comfort
the uh um you know the uh security of having uh you know a nice
job like that but um or jobs like that but uh uh
you know what was it like to say okay this is my last day in doing this and going full time into astronomy
outreach well it was kind of ex it was pretty scary
because most of the people tell you how you gonna leave how are you gonna make some money and i was
uh i i keep telling everybody uh i'm gonna i want to wonder how to earn
money how to generate money but i really want to do this i mean i really want to wake up every day doing this
uh sharing about the night sky sharing about different landscapes and nightscape and use the wildfield
astrophotography to as a tool for a astronomy popularization so
yeah it was kind of difficult actually my boss i told her hey please fire me because i want to start living from this
and i need some money to start with this because i don't know how i'm going to do
it she told me i believe in you so yeah i'm going to fix this and she fired me so
yeah i get fired for astronomy wow i think you're the first one for me
to meet they got fired for astronomy so congratulations i think that um
i think that the uh world of uh the worldwide community of astronomy
will uh benefit uh your your images are breathtaking i i give a i i
told you and you know this i i give a uh lecture uh on occasion to astronomy
clubs and stuff and it's called it's called the uh power of astronomy uh but i was really
inspired by uh karina's uh uh images of people out in front of the
milky way you know and uh of course my talk is all about the
uh you know transformative uh experiences that people have in
observing the milky way uh you know and that healing effect that it can have you know the the way
you can get a new perspective on your life the universe your place in it all
of that and uh karina's uh uh images are not only
poetic but they're beautiful uh and um so i'm gonna let you show your work karina thank you
okay thanks to you but i gotta say that i got so inspired by you scott when we
got that uh told that lecture about the power of stargazing and it was
mind-blowing because you talk about so many things that i didn't know before
that that start like uh it was like a puzzle that all the pieces
start like uh you know like connecting it was so exactly sorry about my english is a
little rusty i don't have the chance like to practice my english here every day
so you're doing just fine you're doing perfect no problem we can we can understand you clear
thanks a lot so i will show you some of my work on some of the chilean night sky
give me one second just to share it um
okay so as i told you all i'm trying to use the landscape astrophotography
it's still in the screen sharing says double click to enter full screen
mode oh there it is i think i already fixed it
great so as i told you all uh i'm really trying to get to use the
astrophotography there wildfield or landscape astrophotography as a tool for
astronomy popularization as you know this is the most similar to our
white uh view uh when we use the wide-angle lens you know it's more
similar to our view to our eyes how our eyes are watching so the people is like
you're turning on a switch to watch what is invisible you're photographing what is invisible to the eye because of the
you know the limitations that our eyes have so well about this picture is in the
atacama desert i was telling uh today earlier to scott that it was
such a mind-blowing night sky it was i'm pretty sure it was aborted minus one because it was so mind-blowing that you
you were able to see your own shadow on the shadow because of the just because of the bright of the stars so
let me just continue as i was telling you i am an engineer i quit my job to dedicate myself to this about four years
ago and i work with astrophotography attile and we're trying to
make more people fall in love with the nice guy with stargazing with
astrophotography deep sky or whitefield that's what we're doing
normally we don't know how to call it like if we're such an icing or something like that but
we're converting astral lovers we're converting more people to watch
up rather their feet yes this is uh well this is our staff
well we tried to create very new ways to
for disclosure for astronomy disclosure so we make tours we
make workshops we make astronomical and astrophotographic camps with people that
really wants to learn about this and they really believe that they don't have the skills to make this so what we're
trying to do is to tell them hey anybody can watch to the stars is something
open to all of us is not just something private it's not something that you have
to spend like a lot of money it's just you just gotta get very far from the city you know all
these light pollution hubs and start watching up and it's easier to connect with the nice
guy when you know it so what we try to do is that to teach people about a little bit about the night sky so they
can know it they can protect it you can't protect something that you don't know
that's basically what we do and we also developed this community of pastoral lovers called casadis de estrellas that
is the star hunters to all the people that really wants to start stargazing or
astrophotography and don't know more people involved in this you know this is
like some people call us weirds or nuts or crazy people because
we really like to be like outside in the field with the cold and
very sleepy and not so comfortable but
we don't care about that because we're connecting watching to the stars so well
we invite all the people to join our community and to keep converting more people to
astrologers these are some of the activities that we
organize with astrophotography atilla we try to also work a lot with
ancient cultures from here local ancient cultures and studied astronomy they had
to plan their lives you know like uh when to hunt
some animals when to start uh i don't know
different things in their lives um what else let me just go on
well and i was as i was telling you um we really have to struggle with
astrophotography as just landscape photography but because we really want to
get the people into the astronomy by this tool i mean it's not just the landscape but
it's the landscape with the night sky it's not just to take that photo is to know what you're photographing in there
what it is in there actually uh all this recognition of the constellations on of the deep sky
objects i make it all manually and to all my students in the workshops
i encourage them to do exactly the same with their photos to know the the nice guy
buy their photos through their photos about light pollution i just wanted to
to get in context uh about the worldwide situation you know 83
percent of the world population more than 99 of the us and european population lives under
light polluted sky is like you know uh many people doesn't know that you are able to watch in the
night sky uh the milky way that here in the southern hemisphere you're able to see the largest
galaxies are the naked eye like the magnetic clothes that they are huge i
have friends from colombia that when they came to chile they cried when they
saw the magician clouds because to see those very big galaxies just at the naked eye is
mind-blowing and here in chile oh i just
well here in chile we have less than one percent of the population
living under very dark night sky and around 30 percent of the population
doesn't live in night skies where they can be able to watch more objects more deep sky objects they
just can see like very bright stars like i don't know the southern cross or orion
but no more than that so they don't know what they're missing well about my
my work this was my very first photograph and it's such a bad one but it's like i
don't know it's like your first child i don't have child i don't have children but the first one even if it's ugly you
love it mine is very ugly but i love it because it was the first one my yeah
it was my very first photo uh what you see in the corner is a light uh
i don't know how to say it i didn't get sorry but it's not uh a meteor it was something from the public
luminary and the one in the right is in atagama in
the mountain range of the makeup and it was the very last photo i made so
it's not impossible to to reach like
more quality in your work in your photos or even in the knowledge you have or
someone had about the nice sky but is to be constant to keep going to the field
to watch up and to keep practicing i think since i quit my job
i have been studying more than when i was in university i keep studying like
every day about different things in in astronomy in photography to keep
developing these skills that i have that there are nothing if i don't study and i don't
keep practicing and learning more so anybody anyone is able to
to reach their goals if they really put their heart into it so about light
pollution should i say totally more than 30 percent of the people live in places where artificial light does not allow us
to see the stars this is so sad because people are very used to watch their own fits or
their own cell phones you know like the very black mirror because they don't have the chance to
watch up actually the last video that i show you this one about
light pollution uh is a time lapse made in dubai one of the largest uh hubble light
pollution actually i went to uh the desert of la ba near to dubai
and it was so light polluted they were so proud of all the night sky they had
and they turned on all the lights off and they told us all the people the tourists in there told us and now please
uh watch to the stars but it was such a bad nice guy it was portal six or
five something like that yeah so that's that's a big challenge in
so many places not only for human beings karina but for for all animal life you
know they all need the dark exactly actually in here there are many places that have
that are um they're so such a great nice guy for example in the
maui region we have a place called uh i have a photo
another slide that is a place that is under a portal one night sky and there is a project a
mining project and also an energetic project that it's gonna
uh screw everything they're gonna
they're going to kill that very yeah they're going to kill that very good nice guy well
about the astronomical tourism we have i think we have a
very a huge opportunity in here that people are not taking advantage of
that we have some of the best night skies in the world and
we really try to to to use this as an engine for the
development of people of the uh of tourism
but uh we really need more support in this part we really try to encourage more
people to make astro astronomical tourism as really need more
hands in this showing the stars uh kitchen how to watch to the nice sky
i i gotta say that most of the people that is making astronomical tourism is
because of the photo they want the photo with the milky way behind they they're not really taking these kind of
stories to know or to learn about the nice guy is because of the photo but
after the tour they get so much more than just the photo and they say it it's like hey i was here
because of the photo but now i know where's the solder froze and with that i can just
orient myself and know what is the south the north the east and the west and it's
all because of this term these are some of the opportunities that
we're having here uh making a mix with different kind of tourism
uh mixing with astro tourism for example with the different ethnics different
ancient cultures from here um with stargazing without the stargazing i
mean not using telescopes even they're making there are some companies making
trekking like during the night to watch different landscapes on the night sky or using
binoculars or i don't know make making horse riding during the night it's just to be
innovative it's just to to be more creative to mix it and to make it more attractive for people it's not just the
technical part so this is some of the uh the other opportunities
that are here in astronomical tourism because i wanted to get to
this about the chill and night sky so you know here we have why we have
this very good night skies is because this privileged latitude we are in the
very end of the world you know so if you go to the atacama desert there
are places where you can see the major ursa you can see it
uh all out actually i have a photo of where's the major uh with reflection in laguna legia
and it's amazing to be able to watch objects on constellations from the
northern hemisphere from here but if you go to the southern part wait that's that's not fair
we struggle to see crux and we can't see it up here
you could see ursa major for your latitude and the height that you can get to in
chile i i i i quit
now i have to come to chile sorry it's a very beautiful presentation i'll
talk more later but i had to complain you can see ursa major that's amazing
yeah that's the cool thing about that we have so many it's so it's such a large country that you have
so many different uh views from the night sky for example if you go to the southern part
you're able to watch uh the milky way during january
uh very very early during the morning but you can see the the
galactic core during january and it's like mind-blowing and to watch
uh in the transition transition night sky for example
during autumn or default or during spring but you can see
the scorpion with uh orion together in the night sky
it's so mind-blowing when you know the night sky and to and be able to see that kind of uh
phenomena like they're together oh my god it's so nerd for some people when i was when i
am in those those transition night sky and it's like wow i gotta make the panorama now because i have both out i
have this very wide uh landscape and i can have both in the
night sky in the same night sky again i want to say unfair but i already
knew that that happens in the southern hemisphere we have our uh folklore about why orion and
the scorpion don't stay in the sky at the same time but that pretty much breaks the folklore right there because
they're the in the sky at the same time you're welcome to come to chile yeah i
i i'm working on it right now actually yeah i want to skip okie text and go to chile
yeah i i'm thinking that's a that would be a better argentina yeah
well and what about the night sky in atacama desert you know it's the driest
the driest dessert right in walls so that's why they have these very perfect
conditions these very perfect conditions to stargaze to observation to
astrophotography actually there was a time i was making a sort of photography with a friend he was
with his telescope and the scene was so perfect that he was able to make uh
uh well to to use his equatorial hormone for
i don't know it was photos of 15 minutes of following because the scene was so
good it was so dry that the sky was just perfect very stable
yeah and well also in the atacama desert you
have more than 300 nights a year with no clothes
man yeah
yes you could easily become an insomniac in chile with uh
those night skies yeah it's difficult to go to think going to sleep with these
nice guys yes yeah and and i know what you're talking
about um with uh seeing the large and small magellanic clouds seeing them so big it is such a surprise
to see how big they are you know in the sky yeah those photographs always they
always look like two little patches but when you're under this night sky in chile and you see that it's just
wow you know very large very big very impressive much brighter than i expected
you know so uh it's um but of course i was at ctio
uh observatory complex it was also very very dark you know so uh i it makes me uh smile to think
that uh chile wants to become the astrotourism capital of the world and um
so uh you know and that would be safe haven for uh for any astronomer that wants to
experience this so carrie i think that you're going to be able to make a lifetime career doing
this and you know we you know we're all encouraging you to keep on very strong in to get it but
we're now we always say that since we more
how can i say it uh most of the people that is working with me in this project
we all quit our our jobs to dedicate ourselves to this so now we are poor but
very happy you know it's like poor just financially uh talking i don't have a house but i do
have my car and with my car i can move whatever i want to go and i can have the chance to get this kind of
night skies for example this is sodical light but it was so so bright that one of the
person that was there with us was telling us hey is that the sun that is racing no because
it was just 4 am so the sun was racing at say 7 00 am it was so bright that for
these times it was not difficult to catch it this was in antufagasta and that was
this is about the north this is also part of atacama desert these landscapes that are so
how can you say it like oneric landscapes that mix it with the nice guy
and this very very bright a airglow that you can see all very green
or very orange because of the air glue
but that's not all because we also have other places if we start coming to the south we have the the
center north part of chile that um where's the elky valley but the elk
valley is not the only one that have very great night skies for example this is pretty near to montepatria it's
another location in the limari valleys that have excellent nice skies and
they have so much richness in culture and archaeological
things for example they have many petroglyph geoglyph uh
most of this are located is the tree is strategically
uh aligned with the nice sky for example there is a stone that had like holes and these holes they used to
put water on it so they use it as astronomical mirrors to reflect some
constellations there is a rock they have all the the holes are in the form of a scorpion
so during the winter when the scorpion is in the senate is reflected in each of
these holes when they put water on it so they knew that they were very close to
the new years for this uh these people for example the agitas or
incas that they celebrate the interim during the equinox
uh in june 20 and with this kind of uh
of this art in the rocks they knew it how to predict it well
this is also under the elk is in kochiwa's valley another
valley pretty near to the elk valley it's part pretty near to the elky valley that it's
really mind-blowing portal 2 night sky the ergo was kind of orange
and green at that time and i don't know if you can oh there is the magnegenic clouds
you have both in there yeah and well this is also uh
some of the places of the ancient cultures located in there that are
strategically oriented with some night sky phenomenas for example where you
have the moon racing during the winter or during the or during the summer and is
and you can see the sun during the summer or during the solstice
like aligned with some some of the mountains this is in the center in here is uh more difficult to get good
night skies as you have santiago that is huge you know almost the half of chilean population
lives in santiago so it's a pretty great hub of light pollution but if you
go to the mountains like i don't know maybe one hour driving you can get into the mountains and lose this light
pollution and get some of the best night skies yes in here is portal 3
we see that's the name of that place uh this is also near that place with
some of the the people that really wants to learn about the nice guy some of my students
and well we also have the snow you know less than what than one hour driving you
get to the mountains in the middle of the snow and one hour driving the other
way to the west you have the you have the the ocean
so it's everything is so near everything exactly in one day you can go to the top
of the mountain to see the sun rising and during the afternoon you can see the sunset
during the same day wonderful wonderful
so this is the place i tell you that there have uh there are people people with mining
projects that are gonna i don't know how to say but this night
sky is have a deadline because of these projects because they want to put all the
companies in there and the light pollution will increase a lot and this place is amazing actually it's
so similar to iceland this is another this is another volcano
this is plankton volcano and actually because of the weight of my
equipment i try to not make like a lot of tracking because they're too heavy
and i'm very small so i try to don't uh do don't
make too much trekking but in this place you can get that you can get there by car and it's boring why
not portal one yeah night sky the air low was almost visible at the naked eye
you can see like the different tones in the sky and well you have all this holding part in there with mikey giant clouds well
karina and it's the southern part of chile this
is the last one that i wanted to show you with the video rico volcano you have so many volcanoes
that actually there are places where you can align them for
example this place is you have the volcano aligned with the southern celestial pole
so it's like yeah exactly to to be able to find those places and
those enlightenments are this very mind-blowing and well this is the
most active vulcan in chile
on this kind of sites where you can watch the night sky is just really mind-blowing and you can reach them i
don't know maybe walk in 20 minutes less than 20 minutes
these are this is volcano guaca volcano
loki mai and this way is volcano jaima well
you have in here you can see in this 360 degrees you can see around 5
volcanos and you can be in the very middle of them
well that's some of the the things i wanted to tell you about this chilean night skies
and let me
let me um make sure i have your website
um that i can share with them there's obviously some people that now want to get to chile as soon as possible um yep
and i'm one of them but i promised maxie we'll be waiting first
big chili i have to go to argentina first so
it will be it'll be higher on the list in new zealand i think i think we're so close
we're so close with argentina we can make argentina and chile make it the same trip maybe that's how
we will do it wonderful wonderful thank you
excellent presentation yeah thanks it's going beautiful presentation
my uh my uh serious comment is that i love the fact that you've taken
the night sky it's not just about the pretty pictures or the
processing with the type of sky you've got you really don't need to do a whole lot
because the milky way's that bright you just have to capture it and you're capturing it out of the love of the
night sky to present that and say this is how beautiful our
landscape is when you add the night sky to it and that the focus
is on that that's that's been my focus for imaging as well and i really appreciate seeing
just how far you're taking it just how far it can be taken as far as outreach goes
so that's uh it's wonderful to see that and hopefully
you know if it's as self-sustaining as it needs to be to where you know you're able to do it
for quite a long time thanks a lot well we're encouraging more people to do this
because the more we are the more people when we can convince to protect the nice
guy and to enjoy them and to connect with them yeah and to make this
perspective effect you know to make this
change this mind change right just because of watching the night sky
actually the very last thing i wanted to share with you if you want to make like the virtual tour
in my website you can see many yeah you were telling me about
these three 360 degree panoramas so
if you're not able to travel yet you can just visit them by
this 360 panoramas
well and thanks a lot thank you so much thank you thanks to you guys
okay so up next um uh we we will go from chile to brazil to
marcelo souza who just finished up his uh his um
i forget which year it is i think the 14th annual aeronautical and astronomical uh event
and so that was uh it was nice to be part of that and um
uh marcella i want to uh turn it over to you
hi thank you for the invitation nice to be with you all of you
chili has a wonderful sky i was there and i used to do very tea
and some peta pacama in the sky is very beautiful but here in brazil we also
have a beautiful sky yes you do i will show here because the
this friday last friday we having a celebration here because they we have
the first black sky park of latin america here nearest near where i live here in brazil
and i will show irisha in
i don't know if someone talks about this because on may 12
it's announced that you have a groundbreaking milkweed result from the event horizon
telescope and what everybody's talking about is that she
probably they will show very immediate the first image of
sagittarius a the supermassive black hole at the
center of our galaxy they already was responsible for the first image of a super massive black
hole that is made here and i think that what
is being shared is that probably they will show an image of the black hole at the center of our organics on may 12th i
don't know if someone knows more about these announcements but
he's right today i say you'll be fantastic yeah everybody's on pins and needles as
we would say in the united states about this so if you're in into astronomy
uh and understood what the event horizon telescope group did uh it is uh it's mind-shattering uh to
think that they were able to actually image a black hole and uh we think they're about to do it again so
yes this will be fantastic if the if they announce
the what they are imagining and and the sun only to show because the
sun is very active i have another x class solar flare
and probably you have another one very near
then this is the message i received today from space red i got you right for my flash because the
uneven potentially very active sunspot group image today and the sun is very active
it is time to look to the sun and to take care
because we are if you have a strong
activity in sample we will have another event like it's carrington
this is what i'm concerned about let you see what will happen in this view
andy we are preparing for the eclipse for us it's very important because the
next one for us here will be only 20.5
there this is important for us here now we have the opportunity to see
how the eclipse the solar eclipse the lunar eclipse sorry and foreign this is time him with you
for ready to be during the night now you begin after
before the 11th and the 30th pm then we will be
doing out the night here in the streets with telescopes see if you have people to to
see the eclipse with yours this is our next year we have here in brazil and
lots of eclipse that's it you can see also in
united states in 2003 but see near us here in brazil
will be a partial like solar eclipse on andy
this is the path of the eclipse is unrational eclipse and here in our
city here is the north asia of brazil they are organizing many activities here
mainly near the situation here they are organized many kinds of
activities for the eclipse in our city we will see like this
the partial eclipse and almost 42 percent moderation of the sun
[Music] and the next one for us will be only march of 2025 the oh
total this is the reason that we
hoped that we have clear skies well because it will be an opportunity for many
people here you know this is the next one 2000 this is for time and data simulation of
the next eclipse and this is what you prepare in this directivity that
we want to organize during the eclipse that is to measure the distance between the earth and the moon
at the moment of the eclipse using only trigonometry to do this
you have only the triangles
here and then we can make use the only geometry we can
and the proportion of the two
triangles we can measure the distance between the moon and the earth
now i have it from since c i believe that you have it
two weeks that we organize events with
one day after the day day after day the first one was the
the international meeting of astronomy the fourth that is quite participate thank you so
much to anticipating our events we are amazed off the event in the field of our
seats this is our group right we have here many students that
participate in our groups and most of them participate in the project that you
have in support of the uh the consulate of the united states

this is a guy from here that produce a program about our events
yes part of what's happened here
yeah the invited speakers that's why here you know i'll see it that
participants are here perhaps also this is dark sky park
near us that the first dark spy part of the latin america our students talking
about astronomy and this this student
she has a nice steroid with her name he is a famous as photographer here in
brazil this guy is a student to 17 years old
that he already solved the icelandic equations and his work with zyracus
equations raising the lushy of high school here
i'm very smart we're talking about asteroids because we are working with asteroids now
well and they bruno points the girl that i said yes
she has a nice sterilizer for her name that's bruno points the name of the asteroids

organized the international meeting we organized the driving of another event
two days of skype
he had characters and we have cars there people arriving cars
and they see our presentation there and we have a big screen to talk about
astronomy and the participation of the characters here
this is your telescope that you donate to us we use it for today yeah the event
here is our team that participate in this presentation and the
is the biggest shopping center for our city here is the first
international black sky park in latin america is located near us here
in our forest the big forest that you have in the others and here you have the inauguration
of the dark sky park this last friday here is the
party the recognizing that is and here is the event that you had there
[Music] only 10 000 people that live is there it's
very small city and they are celebrating this we are doing a new achieve to that that
is a planetarium in in an open space we use a green laser to
show the constellations there and here we are seeing the
south vision with the southern cross carina
and the the only the big machine cloud that you could see
and they also we saw the false cross and the geo boxing omega centauri is a
fantastic place and they have an
i don't know i hear the sounds but they can say they are playing
the star wars
what a celebration yes
that is wonderful
you see the lights here how the lights this is only the headquarter of the
the dark sky park that's located 20 kilometers far from the park
inside the park they don't have artificial lights they don't have power
and the park is so big that it has part of the park in three seats different
seats here's the everybody's looking for the south and cross here i was showing using
the green lazy i have presentations here
and here and they also we organized events
after the the celebration for the young startups tomorrow in
schools us we already visited 31 schools
we are here i think that in the end at the end of may will be
we will be in 40 schools different schools here are the students that participate
in these events
here they are looking to do some refugee glasses special trends program it's wonderful
and one of the students today she received the congratulations in the
councils i don't know how to say anything but the city council houses this that to say
where you have the people that make the laws for the city then they give
they send congratulations to these students here for her participation in the project he
is responsible to produce c apps for
smartphones she's very young and she already knows how to make apps and she's doing app as
far as ceremony like a variable stars now about the us
space exploration about the audio rockets that you have in the world
so this is our activity thank you very much for it
wow wonderful wonderful congratulations on your successful events and uh your continued
uh inspiration in all the education you're doing in astronomy with your team
marcelo it's wonderful it's wonderful i'll remind the uh audience too that
that marcelo is the senior editor of sky's up magazine it's
a global astronomy magazine you can get it by going to explore scientific dot com forward slash skies
up i'll put that in the chat here for you to go and get your free downloads
but right now i'd like to introduce norm hughes norm is uh
often on our chats i believe this is your first time on global star parties is that right norm
yes okay all right so let's uh let's go ahead and bring you on and uh we're
really happy to have you uh be part of this um let me welcome to the big time norm
yeah let's bring on the real amateur now here we go i love real amateur so it's
it's uh it's wonderful because um uh amateur astronomers well the the name
implies that you love astronomy you know amateur exactly and so
and uh certainly we know that you do and i do yeah about probably 90 of these global star parties
i've only missed them because i work so yeah that's a this is pretty awesome stuff i'm honored to be here so yeah
we're honored to have you so we'll see if i can get it over to you but uh before i do tell the
audience a little bit now i know that you're in the chat all the time and people are always uh
telling you hello and howdy and all the time but uh and i i see you joking with you with the
your friends also in the chats and i love chatting there with you as well but uh uh tell us
more about how how did you get started in astronomy i mean what bro well long story short
i went to carlsbad new mexico in 2011 never looked through a telescope my life mid 50s or early 50s
my boss was in charge of the dark sky program there and his name was chuck burton i don't know if you have ever
heard of him named charles burton he's pretty known in the telescope industry and he had a beautiful picture of orion on
his wall and i started questioning about it and that's when i learned he was doing the star party so he invited me to the next star party to come just hang
out with him okay so i walked up and he had like a 30 inch dobsonian i looked at what do you think i looked at saturn
and it just blew my mind oh yeah and uh so shortly thereafter he uh let me go ahead and share my screen and i'll show
you a picture shortly thereafter he um uh okay you see my screen
not yet this takes a little bit of practice you you have to go and press this
and then you select which which uh you're gonna see all your thing you select it and then you commit to it all
right i've got them also i got it selected um you see my desktop the moon not yet i think there's a button you
have to basically go share screen there's like one more button to hit yeah and then it'll actually do that there
you go there you go i thought i hit that i hit it but it didn't want to work so all right so let me uh
so anyway he um the the park had a telescope that nobody was using and he
said why don't you sign it out learn how to use it and um
sorry the picture's small but i downloaded this off of uh my facebook page so here i am this is an
atlas eqg with an 11 inch orion my first time i didn't even know what alt az was
and so i'm reading the manual so my wife snuck out and took this picture so this was my start in astrophotography
so he didn't give me the hand controller he said you're going to learn the sky by push too and so for the next two years
i used this telescope every night at my house that i could and at star parties and learn the nice guy and then i
stepped off and bought my own telescope and kind of spiraled downhill from there so [Laughter]
um and i bought an lx90 which was a great scope did a lot of
moon and sun and and super super super short dabbled with orion and stuff really
bright and then i got um i got the bug i found a website which
i'll show you here in a minute that got me into actual photography and
i dabbled in it for about three years and then for the past probably three and a half years and then about six months ago i started i thought
well i'm gonna get serious that i played i mean i didn't have my perfect polar alignment i just took pictures and
stacked them and a little fuzzy here and there and had problems but i was proud of them you know so i decided six months ago that i would
get super serious so i tore the telescope apart fixed it did everything to it greased it all that kind of stuff tightened up worm
gears balanced and double balanced in polar line and got my gear all set up and and
this is my setup now so um it's a full-blown
run from the house it's totally automated um and look at that
12 inch mid 81 millimeter um williams optics and then my little 60 millimeter guide scope that's a 294 a 290 and a
canon eos r8 um and so i switched these cameras back and forth and this is mono and of course
this is color so this is my setup now so um that's uh i'm fixing to build me a
little observatory as soon as these spring storms break so get it built on top of it right now just
put the 360 cover on it so sure um so yeah just a couple of quick
pictures that i've taken now i'm going to get off onto some programs for you guys um this is uh
all narrow most of us narrow band stuff um of course this is pac-man um
and this is a color image and then uh this is my orion i just finished
um i wanted to try to capture the dust and so i set off
this is 276 images ranges anywhere from two seconds all the
way up to 600 seconds and i wanted to capture this dust here and i
think i did a fairly decent job at it there this thing's loaded with flaws that the data didn't want to play nice together
it took me forever right now with this image i want to give a shout out to sean at visible dark if you guys aren't using
his tutorials you should because i probably had 20 tutorials i watched to get to this
point um and if i could if i had the minute i would show you i would show you where we
started with my orion and uh to get to this image but most of
it was done with shawn's tutorials so he has some amazing stuff so that was my orion i was really glad
i got all this dust back here so and there's a little waterfall you have the waterfall in orion there's there's
the waterfall right there um it's a little h.a out oh yeah check that out yeah it's it's there well it's
called the waterfall you can it has a name i don't know what it is but i mean a designation so
um then uh uh i just when i started i thought i said getting serious that is my m51
this was my first ever galaxy to ever shoot and uh of course i got a lot to learn
i'm still new at all this processing stuff my rosette nebula
um and then this one i'm kind of i was glad to have i was after this i mean this is
m46 everybody knows what m46 is a beautiful cluster with a ring nebula out in front of it
but what i was after was this little guy right
here you see him right there that little guy that's um
pk 231 plus 4.1 there is no information about it on the
internet to know how far away it is whatever whatever whatever there's nothing about it but that was that's what i was after i saw it in another
guy's image and this whole thing is just lrgb 20 20 minutes on each filter
and this was all processed with one of sean's
start to finish tutorials and it turned out pretty sharp so and then this is one i didn't get to
finish my witch head so i needed more data to fix this up here you know but this is a tough object to get
but that's just some of my images um i flex i've just started getting really serious at it but i do want to real real
quick is run through a couple programs that i use i i mentioned this in astral tv's chat one night
and nobody's ever heard of it and this is a program called astro coaster this is a great program it's free
if you're like me i use the skyx to control everything my telescope
camera filter will auto guider everything and i don't use sharp cap or anything
like that this thing as much as this thing costs it has a terrible fits viewer when it
brings up your images um so you can see that's what the images look like in a program as expensive as pixel side so
they're pretty terrible so for a lot of years i've been using the
um astro toaster and when you set your you can use it on any with any program um when you say your output file
then when you set up toaster and you go to settings you just pick your input so you're going to grab that folder where
your other program is putting your images into and it'll just pull them in as it dumps one in azure filter pull it
in and stack it it's live stacking on the go it's a great way to see what your data
looks like you know before you get into the heavy you know processing that we do with the images
this is quick down dirt you can make all kinds of adjustments on it um you know you you load it up you monitor
stack and refresh and it'll just keep bringing images in as you're downloading them off your um
uh camera so it is dependent on um
deep sky stacker so you have to have deep sky stacker that's how it runs its algorithms through deep sky stacker so
you have your deep sky stacker folder right here just you just have to pick deep sky stacker in
x86 and other than that it's a very simple program to use it'll stack them
when you get fresh the new image see there's my light pollution with all my led lights
so that's the power of this program and just hit auto expand and it does an algorithm to determine what's the best
settings for the image and it takes a second it's these are big files so it kind of struggles and then it does that and you
just start playing with your adjustments and and tone it all down however you like and there's all kinds of contrast and
but it's a great program it's free and it's great for on the fly
so um it's at astrotoaster.com if anybody wants it like i said it's free he just released a new version it's got
um like toaster like t-o-a-s t-o-a-s-t-e-r yes sir
um you can do different stacking modes you pick your uh here you're going to pick whatever file
you're using you know to do it and then you can go into stacking mode it could be used for narrowband images you can go in all
kinds of stacking modes you can assign your channels and it just works it's a it's a great little
program and it's it's it's awesome i use it every time i image i just watch my images as they come in
to see what the data looks like um pretty pretty pretty nice a pretty nice
program and it's free so the last thing i want to do not going to take a bunch of time is i want to
introduce you guys to a website um let me pull this up over here
i've been a member of this website for since 2011. um it's called nice guys
network it's owned by a friend of mine named joseph sardina out in new jersey
we're really good friends um there's this is where we live broadcast all the time i'm surprised
somebody's not live broadcasting tonight um there's many people that have channels on here
and we just do live broadcasting and you come in and everybody chats and and everybody can talk and it works on any
platform phones it doesn't matter you can you don't have to be a member to come in you can just
go to not newnightskiesnetwork.com and you can just there'll be a blue button here that's what's called big blue button new
night skies new dot yeah new.nightscattersnetwork.com
and there'll be a blue button here you just click on the blue button and you'll go into their page and the chats over there i wish
somebody's here but right up in the corner there's three dots and you hit that and say leave meeting
and say okay and then you can type your name in and rejoin the meeting and then your name will be in chat so you don't have to be a member to come in and visit
um but it's free you can sign up if you feel like you ever want to try to dabble off
into live broadcasting um there's a lot of us that do it
um from all over the world with people from australia new zealand um england
canada all over the united states that come in here in live broadcast some nights you'll see three or four you know you see people during the day from from
like australian stuff and a lot of sun and stuff like that so i just wanted to kind of introduce people to this and
give you something else to put in your things to play with and come in and visit sometime at night skies network so
it's a great little program but that's about all i have scott i just wanted to um come in and
and enjoy the program and yeah we're really happy that you joined us norm i
got to find out those are those are great images and proof that once you get off into this
hobby you tend to you just go with it it takes over
and you know you start like everyone starts with an image and the images then uh
you know they they begin to show more and more detail as you keep going and
after a while you're when i started my journey my images were obviously terrible you know i lived in a bordeal
eight sky and you know but i posted my images anyway because i want people to know that you don't just
automatically make pretty images right it's a it's a long road to get there a lot of
it's also too i think we all develop an idea of what we do it for
and as soon as you get that then your images start to take shape you are after something specific with your orion image
you've got plenty of images with the orion nebula and the running man but you were after something specific so when
you worked at it you ended up once you got the results you uh you could sit back and go wow i
may have gotten more than i thought i was going to get yeah easy i did um but yeah you're right i mean i got tons
of friends that are have never looked through a telescope and they love to see my pictures on my facebook
page and stuff you know yes that's that's that's why they keep you going after a while they become to expect that
you're going to post something yeah and then you're yeah i get asked all the time how come you haven't posted anything in three or four months so well
it's raining you know yeah it's been raining for three or four months yeah this is our tornado season so so yeah
that yeah that that's that's part of uh the the reality check uh yeah i wanna
some of the images that i've been picking as i've been watching the presentations um i decided you know what maybe we'll
maybe we'll share a little bit of a reality check why it can be so hard to get the images unless you go to a
beautiful place like gary basically what had me wanting to retire right now and
just pack up and move to chile under something like that for
i've only gotten a taste of dark skies from uh okay techs and i don't know norm if you've had a chance to build a border
one and look at stuff yeah i lived in new mexico i lived in new mexico it was mortal too okay um for
three years yeah you've seen a dark you saw a dark sky for days on end so yeah i've seen i've seen
so many stars you could you could make out the big dipper you know yeah so but my friend joseph sardina that owns
that side and another one of my friends and scott you've had um francis walsh on once showing you
um i think he showed you the observatory down in texas that my two friends have
we have a lot of gatherings down there it's a border to sky so it's a that's what we're going for the solar eclipse
right down there in texas uh in hill country right yes i challenge you all you're going to be
at a portal 2 sky because i don't know that i'll be able to do it but someone might the the lunar
well the moon is going to be around um antares i believe when it's uh
when it's you know blood red and as you can see from the image i've got the
galactic core is going to be underneath that until i realized that i had signed up to
bowl that weekend i knew exactly what shot i was gonna go for
i was gonna go somewhere dark hopefully it wasn't gonna be cloudy and this was gonna be epic and then i realized i had
to bowl and i said no i'm gonna be in vegas
so it's i hope somebody gets the image and look that i would love to get and uh
you know we're going to make sure that this never happens again where a nice astronomic event gets blocked by
anything else in life that's it it hurts me to know that i have to
i'm gonna be following it online but um i i'd rather be out there doing it i mean
i may sneak out of the bowling center and try and steal a shot before
running back in yeah we'll have to we'll see what happens you know maybe maybe fate will be on our on
my side i don't know but uh that's yeah that's gonna be a really
cool day um a lot of people will be looking up in that day and i'll be encouraging i'll be
encouraging bowlers to look up uh forget about your scores and just go look outside at that eclipse um and
maybe if i can't see it maybe i can get a lot of other people to appreciate seeing it and um
you know i hope that that works out so great images norm yeah thank you
yes if you didn't chance norman if you uh i for some reason didn't get the uh url
correct for uh the net night sky's website but if you could either post it here in chat or
yeah i'll put it in chat okay and then appreciate you um let me have some time and and i hope to it again i
want to do some um that we get in the summertime maybe some other star parties have for live views for you to fill in you know be awesome
that's what i'm working for so yeah and i appreciate the time and everybody uh um
everybody's been great tonight i appreciate it thanks god thanks for being a big part of it oh yeah thank you
bye-bye okay all right so uh gosh adrian uh what did you think i know
that you were really impressed with the the night skies down there in chile so yeah uh but uh yeah you are no slouch
yourself you make beautiful um deep sky images of our milky way and um
uh you know i'm i'm uh always impressed to see what you have you know because you're
you're a great photographer and uh it shows every time i appreciate that and
actually that's the way that i'm going to do my presentation scott is to show
what does a nightscape photographer do when his area is just too too cloudy
so this is this will be a journey of what i shoot
when there's nothing to shoot and what you do when there is something to shoot so
[Music] let's start with um
let's see we'll we'll start with one of the books that i'm writing and trying to do
is this place on a rare clear night in my state is point o bark lighthouse park and i'm
interested in making this a dark sky preserve i'm trying to get in contact
with the folks that um work with this start that take care of
this lighthouse um it's a portal it's a true bortle three sky out here and um
it would be nice if headway could be made things like the light that they have here they had here that night
if that's turned off if they're able to turn off some of the other lights on designated nights where it would be
stargazing this place would be perfect for that um so
this is one of the one of the bold goals that i have is to make this and you can see kind of milky
way here is with the exception of the lighthouse we'd let the lighthouse do its thing
because that's you know it's it's an important function but if the rest of the lights could go
off for a specified amount of time this would be a beautiful place to image
however the reality in michigan is this clouds
um so here i am i thought i was going to get a pretty good night and then clouds
drift in a couple of the places that i go in michigan i think it's going to be a good night
and clouds drift in so i just take pictures of the clouds
sometimes i get fortunate and the clouds recede
and when they do i'm looking for a couple of images in particular
well here we have a lot of clouds so you've got the there's that same area and you've got
that you know the kind of a cloud slash um seashore mix
so you try stacking your images and i'll see if i have the stack
um not seeing it it may be this one
well this is so this is the this is one of the images that i took
there was a stack but i'm not sure i brought it in the folder and there's i
won't worry about it i'm going to give you i'll give you all a story behind this image we'll stop
here on this one where you've got some cloud cover and you've got some uh you've got the milky way rising
yeah look at that
uh we lost your audio adrian okay can you hear my audio now got it
now yeah yeah the mute is in front of it and if i if i touched it
i know how it does yeah that'll uh that'll be useful for you later scott but right now the story
the story is um so it's a heart it's a heartwarming story because
this is this was one of those ways of using night photography
the gentleman who passed away on one on january 3rd
i worked on processing the donation that he gave to
our astronomy club and so in looking in a death certificate i looked for the time he was pronounced
dead it gets morbid but it gets heartwarming 8 25 a.m on january 3rd i looked at my
um sky safari pro i looked at sky safari pro put it in on
january 3rd 8 25 am and to my surprise this was the sky that
was up at that time but the sun was right on the horizon where around the
area where in my picture i've got a uh like a glow from a distant canadian town here
that's where the sun was and the summer triangle was in the same position
so this photo i told that to his brother i said this photo
shows you what the sky looked like except in january the sun had broken the horizon
and m15 had broken the horizon over here we want to pick out a star
forum we thought about maybe one of the stars of delphinus this uh top star here it has a name
but we wanted to designate it in honor of his brother and what i told him i
would print this out for him and mail it to him and he could put this picture the
picture of the sky at the time of his death with his ashes
and as a memorial so this image is destined this uh summer triangle
rising is destined to be a memorial picture for a gentleman who passed when
the sky looked like this on january 3rd so to me
our night sky images can mean more than just a picture and
even the type of outreach that we do may go beyond just pointing at the north
american nebula or delphinus the dolphin or the coat hanger and saying look at
that it may have even deeper significance to someone out there so
you know that there's a lot more that these images can
do and um so i this image
you know taking the image i may not have thought of that but then going back and referencing it
it takes on even more meaning so that's um you know i think the importance of
showing the night sky can go beyond these sort of things this
is a similar type of image it's the small version so i'll zoom in
so the quality may not be as good but this is a view the uh church that was over here st paul
on the lake i gave them this image because they may be able to use it this is the
view from their church and um this was the moon rising over a
lake that their church is uh excuse me situated on and so i shared it freely
with that church and that is uh that was basically what i did
to um share the work that i'm doing so now you're seeing a lot of there's a
lot of other images here and we're going to so we're going to use those to tell the
story you know shadows was a part of the story that we uh tell
and here we have shadows on the moon there's a difference that capturing this
quarter moon and the next quarter moon i'm gonna show can make
just by the location of the shadows there's lunarex
and lunar v this is this is a quarter moon a first
quarter moon captured when the shadows sat in this location
revealing these features on the moon that this makes it look like an x and it
looks like a v and they're mountains and ridges these are craters
that border this region and because of where the shadow is
it creates this little illusion for us and it's one of when taking pictures of
the moon it's one of the illusions that i've tried to catch
numerous times this was one where i was successful catching it this one and maybe this may have been 30
minutes later um i was unsuccessful there's the lunar x but you see the
difference it's harder to see you recognize it the shadows over here but what you
recognize is that you've got this region and you've got the three craters that border
that side and then the lunar v is here but it just looks like a part of the terrain
so when you take your photo can be important shadows
can play a big role in the areas of the moon that you try to look at
but of course where we are it can be cloudy so this is what it looks like to the
naked eye sometimes when you go out and you can't see anything in the sky
you take an image and your image looks like this
there's no clouds at all in the sky this is what we're faced with a lot
so there's my bowling ball that i'm taking with me to vegas
and that was it that was all that i took a picture of
so what do you do well you do a few things you go out
nature you go out and shoot at nature so then you you share the cardinal
you look at the baby owls and you um
let's see those are the only two you go to baseball games where
one of your stars in detroit that's one of his 3 000 hits
that was hit number 2998 and your favorite team
your captain of your favorite team breaks it back but the team wins that night so you take your equipment and you
go out and you shoot that then when you have the opportunity you shoot um
you shoot images like this where now you're aiming at people this is little luna who um
was a part of a uh was it it was a um
the rainbow connection it was a charity event where a lot of donations were made
and that was the very last picture this was the very last picture i took after we got this cute photo we just
said okay we've got enough so so we stopped there then
we take our this is my daughter whom i took out to dinner before coming on
and um she's all growed up in 16. so we have to point our cameras at other
things when our skies look like this where you can barely see any stars so
so you end up learning how to do photography here's a here's a nice landscape for you scott
couple geese flying oh yeah in this area right here so this is regular landscape photography
but then if you go to a portal once right i mean it's still all part of the universe yes it is
so we call it landscape astrophotography because you've got a landscape like this
it's photography but then you can go out here
and now you have astro photography and this is the sky glow that you saw in
chile and some of the red colored sky glow this is of course oaky text i have a
choice between coming back here or going to chile i i would take the
option to go to chile i still have to figure something out there but uh okay text will be cheaper
yeah yeah it will but i will tell you this is just beautiful to see
um a couple of the pictures that i took out there last time were pictures that accented
the colors but represented what you see with your naked eye
and there was one of the zodiacal light with the moon in it i didn't find it in time but it's okay and i think i've
shown it before um and then the panorama i think this was
yeah same camera um the skies are absolutely beautiful
and right now here's the pleiades over here mercury and the moon will be close by
um glenn roberts who i think was on uh earlier this would be something great to go out
and try and photograph if you can at sunset um it makes for you know these things make
for a beautiful photo and the panorama this was the group i was with university lowbrow astronomers
and it's he i even got stars this was interesting i have stars in the reflection on this truck
that's neat look at that oh yeah very interesting oh and there's
a beehive right above it so you never know what you're going to get
when you take photos now of course if you go out and you get your modified well actually before i show the modified
camera view this is with a non-modified camera if i am not mista you know it's not this is
not a modified camera and this is how much data you get in a border one sky
the hydrogen alpha regions do show up not maybe not as well as with a modified
camera all of these streaks are very likely planes satellites maybe a meteor
lots of streaks in the sky on a sim this was a single 30 second exposure
and then then you bring in your modified camera
and you get all this data in 30 seconds and you even get things that you
normally don't see at my normal latitude like the cat's paw
and the um lobster my goal is to try and go somewhere where
i can get even deeper and see if i can get a little more i have to be careful where i venture out
though there at night when i go to okitex and of course this image for readers of skies up magazine
is the original image that um you later saw
and what i like about this image is the fact that you saw the other milky
way a lot of milky way photography is done with the galactic center
but especially at a dark site you have the opportunity to take other
regions of the milky way and make them just as prominent with orion over here maybe this is the
witch head a little bit of it maybe it isn't or maybe it's this area right here just around you know
next to this it could be this area here but
the whole point being there's nebulosity here that you can capture because the skies are so dark
and you can focus on different regions of the milky way and you don't necessarily have to shoot
the same places that um that we all shoot you know when we're aiming to get uh beautiful skies
so so when it's cloudy and you have nothing better to do continue to take photos
and hone your craft because you never know when you get to a clear sky like this
you want to be ready to take advantage of it and if all else fails if we've learned
nothing else we just need to move to chile or to argentina with maxie
and just get better skies and then life is that much better so uh
so that is my winding presentation what i've been doing over the last couple of months and what i'm looking forward to
all the way in september um in the meantime there are some dark
skies to the north in michigan and it's my hopes to go back there and
take some photos as the milky way does continue the galactic core i like to call it i don't like to call it
the the picture behind me is what's going on with the um galactic core
in the early morning before sunrise which is when i took that picture behind me
and um that was the portal 2 zone and that was a minute long exposure and i was
that was the first time i saw that much detail including the region um behind me
a part of the galactic bulge that you know i was quite pleased even though i missed the initial shot i wanted to
take that was 30 minutes away the sun came up before i could take that one but
i would do it again because this was a wide open field and it was beautiful just to see
so uh so with that i'll turn it over to you scott all right thank you for always
having me on and even when i have to be late i'm always happy to come and share my images
always welcome thank you so much all right so um uh we are
uh we we uh we're uh expecting to see cesar burlo to come on uh this
particular episode but he promises to be back on sometime next week so
um we are going to finish the uh global the 92nd global star party with
maxi falaries down in uh argentina and uh so we've
crisscrossed the world a little bit here but um it's uh always great to have maxie on
with his amazing images of the southern hemisphere maxie how's it going man
hey scott adrian norman and hi everyone well that's
we missed the the last gsp last week but
you know we have too much time to to to
do what we do so basically um well i
i was doing last sunday the the 24th of april i think it was yeah the
sunday 24th let me share my screen um
i was trying to do some solar images and
because the sun has too much activity but not in this case it's my
my background uh let me show you this picture that i did
of the sun you can see the dark spots uh
really really clear even i i was i i was struggled with the wind and the
clouds but sometimes i had some kind of a windows
that i could take in shots but also when i realized and the
in the moment the the sky going very clear i saw
the moon like this oh i like that you know i i i it's very cinematic you
know like yeah something you would see in a movie you often tried to catch the moon like that at times
it's an awesome way to show the clouds mixing in this is another one
with a little more exposure but it's like a smoke but it's clouds
and and of course it was really writing and
this is what i the the one that i really like because the
it's like a fog across the moon it's very very
particular picture and and this is only one a single image uh i
don't i did it with my zwo and the telescope only
um i think it was at 0.0001
seconds and a 100 gain i think
so basically that uh that was i doing that sunday it was a really good
sunday but then i had to prepare because the
the friday 29th i have to
do a presentation for the 28th edition of pro science
this is a [Music] um a program that a
organization teacher of physics and he invited me to do a presentation for the
first time you know i oh that's cool yeah and the most cool is that i
start in astronomy i don't know almost 20 years ago
in the 8th or 9th edition because i always
go i went to um the astronomy
meetings to do observations i remember controlling the course a show was showing us the joke the joel
a box cluster the omega centauri and another southern
objects and it was really cool and in that moment
a also i realized that i wanted to do astronomy well of course then
astrophotography so uh you know that's the good of this uh 20 years ago
i was going to that presentation and 20 years later i was presenting
to everyone so this is a part of the group that came
here are some people that i know but also here back here is my my dad i'm my brother
so i was really really happy to they went to be there
and here's me doing the presentations
these are a kids from a school that came more later
but they they are very curious i don't know if they are excited to go there
because you can see it was really cold that night
but uh then of this i we did some
a little of celebration but we have too much
light pollution but we try to do some some kind of
uh i did a presentation like an hour maybe explain explaining a little more
of a the story of the astrophotography but
also what was in the past doing the observations doing
drawings and and that's was the kind of a moment that
you can capture something in the history of astronomy but now you can do it with
a cameras you know of course i did of course with a hubble telescope
it's a very very special camera the
the the mirror is 2.4 meters of diameter
and that's a huge one that i think nobody
can get that but i want to try to show to the young
people and of course everyone that wants to to learn about it and that you can do
it with small telescopes like this you know here's a maxwell
that i practically started and well uh
they they like the the the presentation and they they give me a little
um a present that says that that they thanked me
to to be there and of course i'm really grateful to to be part of that
so the next day the 30 the 30th of
april we have a here in the south the partial solar
eclipse i went to a rural a place that
you know you can see i i didn't know that if i could be there because
it was a really close cloudy day and it was really cold also
but and i was really tired uh i i
woke up from a a little nap that i took and
when i saw this open skies i said to my girlfriend
do you want to come with me okay let's take some mates and try to to see what we get and also
taking pictures so you can see the cows when we arrived to this place
we went we cannot uh across this this farm
no no you a weekend but hey we stay in the in the in the entrance
but this cows it was almost almost almost 40 cows here
moving moving but then they went off
so i started taking pictures with a
a mylar filter that i had but
you can see they're starting to get in some clouds and anything in this case is
i don't know the reflection i can see it uh it's starting to to go in doing the
eclipse but then the the clouds cover up and i'll say okay that's it that's all
that i get but well here's belen
watching the the sun i i take this picture surprisingly but she didn't like
it so i realized that i have a little window
very above the horizon uh and i say oh maybe i will i can wait
and then i i start to see the the sun going down and with this particular
a shape of the moon but this is this wasn't with the filter this was
only with the lens uh very carefully taking with the
diaphragma because the light was really bright even here in the horizon
and and taking pictures very fast exposure
and i remember i was running because i want to see if i could go with
a with this between these three big trees and taking
with us a little trees there and this is another one
this is a practically above the horizon and you can see look at that that's cool
that's the old kind of eclipse that i have here in my life
beautiful i i can i really really love to to try to
to capture it so [Music] i hope well let me show you
this is the saturday image of that day
let me see if the animation goes okay for example
i'm here you can see my cursor of the mouse
i'm here this is a buenos aires promise but i'm
practically i'm here so there was really cloudy and
let's you can see the the darkness let me
put it back here's the open it
window that i have in the clear sky but
look at here more to the south
let let's go back that
here in this place in the ocean is the shadow of the moon
it was minimum but oh yeah but you got it
in more going up oh sorry er
start to you can see the edge of the of the earth
in the day and the night but here the this is this is the the shadow of the moon
part partial
let's see if it goes with the animation but i don't know
so because in this place it wasn't it was in in day time
in that place even the it was darkness so well
this is my little presentation i hope you liked it and well i hope to
i think i will go this weekend to take pictures with small equipment to
let's see what i what i get maybe to the raw fucus place i think
but i hope the next week to to get captured with the with a
total lunar eclipse from here yeah absolutely
wonderful maxie thank you thank you that was a beautiful image thank you
good stuff yeah that was a great capture yeah thank you guys the moon with the clouds
are pretty spectacular yeah i i posted on my flickr account if you
want to see it let me i will share it here in the in the chat my
flickr page here yeah
i have a flickr page too so oh excellent you can share your screen if you'd like
maxi okay [Music]
okay oh yeah let's get it this is my flickr
a page this uh what i what i started to do
a couple i think one year ago almost were here's the total solar
eclipse in the 2020 yeah
this i really love too and of course well the moon some
galaxies here the telescope and the moon
in the field uh this is the reprocessing
of that moment
here's another one it's more like a sharpness
and this here is with the flares i i really love this picture
and of course of the topic of the of tonight was the the lights and the shadows and this is a really good one
example of that it's beautiful
i i i can imagine now if the eclipse uh
occurs because we have too much solar activity so
it's gonna be fantastic yeah i hope that in 2024 you can make it to see the total eclipse
yeah i hope it too i hope you too wonderful
all right gentlemen well thank you very much i want to thank uh all of the people that were
on global star party tonight that would have included david levy um carol org from the astronomical
league david eicher from astronomy magazine
bob fugate he is the actually the father of uh laser guided
active optics he was on earlier samantha jewett from the royal
astronomical society of canada uh we have molly wakeling with astronomy's universe
dan higgins and peter from astroworld tv we're on we had michael carroll
space artist and science fiction author um carina letelier
showing us amazing skies in chile and her incredible astrophotography of the milky
way down there marcelo souza from brazil norm hughes who's right here with us
right now uh uh maxi fellary is also with us and adrian
bradley with this beautiful nightscapes our dayscapes as well so yeah anyways it was a great um
global star party i really thank all of you for participating and i want to thank the audience for watching from
around the world and uh i wish all of you a good night and i
wish that you all keep looking up thanks scott we'll be back next tuesday with global star party 93 as we march on to
100. take care and good night take care guys good night
