Global Star Party 144

Transcript:

place that she's living in and it's just lovely that is
great okay we're going to run this whole
video on April 8th 2024 portions of the United States will get to enjoy the
sight of a total solar eclipse the last time this took place was back in August of 2017 so this is a good time to
refresh our memory as to what's going to happen why it occurs and let you know where you watch the show in the sky a
solar eclipse occurs when the moon moves between the Earth and the Sun blocks the Sun's light and casts a shadow on the
Earth when the moon completely covers the bright disc of the sun that's a total solar eclipse this differs from a
lunar eclipse where the moon moves behind the Earth so it's now the Earth blocking the Sun's light on the moon
creating a shadow on it with a red tint to remember the difference just remember what object gets darker with the solar
eclipse it's the Sun and during a LUN lar Eclipse it's the moon because the Moon Shadow is relatively small a total
solar eclipse is a pretty rare event to see in order to do so you have to be on the sunny side of the planet and within
the path of the Moon Shadow and that path is affected by the Earth's rotation moon's orbit and where they are in their
orbit around the sun there are a lot of moving parts that go into creating this incredible site and speaking of parts
during a solar eclipse the Moon is actually casting a shadow consisting of two parts the Umbra and penumbra the
moon's Umbra is the part of the moon's shadow where the entire sun is blocked by the Moon in space it's a cone
extending about 232,000 Mi behind the moon it's when the small end of this cone hits the Earth that a total solar
eclipse can be seen those factors are why only a limited number of locations on Earth get to actually see it so if
you find your area in the path of totality this year treasure the site because on average that same spot on
Earth won't see another total solar eclipse for 375 years the area around
Carbondale Illinois however has hit the cosmic jackpot getting to experience this year's Eclipse as well as the one
from 2017 but their next view of a total solar eclipse won't happen until the
year 2343 when you check out an eclipse map
that depicts the path of totality keep this in mind while many Maps will show a circle representing the Moon Shadow
the true shape of the Umbra is more like an irregular polygon with slightly curved edges this is due to the fact
that the moon isn't a smooth sphere it has mountains valleys and craters on its surface all of which affect the passing
sunlight and shape of the resulting Shadow NASA's lunar reconnaissance Orbiter spacecraft which has been
orbiting the moon since 2009 has provided scientists with incredibly detailed photographs terrain maps and
other sets of data that have allowed us to better understand the shape of the moon's surface this in turn has given us
the ability to create more finely detailed maps depicting which specific areas on Earth lie within a solar
eclipse's path of totality regions outside the Narrow Path depending on their distance from it we
get to witness a partial eclipse to varying degrees as you can see the pumers shadow passes over almost all of
North and Central America as well as Greenland Iceland and the Western British Isles this 2024 total solar
eclipse is therefore giving millions of people the opportunity to share in this rare and dynamic interaction between our
earth sun and [Applause] [Music]
moon on April 8th
[Music]
2024 the gabt solar Patrol program is a heliophysics program aimed at citizen
scientists and K through2 students both locally nationally and throughout the world the goal of Gabbert solar Patrol
is to monitor active regions on the sun in order to understand how they're connected to explosive events that we
categorize under space weather participants can remote in and actually control the telescope themselves so a
common observing mode with the gabt solar Patrol is that we'll have classrooms actually operate the
telescope themselves collect some data and then generate maps of what the Sun looks like at radio frequencies they're
gaining a really unique experience that I think is is really special to the gabric program um and that's the ability
to walk through the scientific process from the very beginning from the steps of collecting the data themselves all
the way to reducing that data and interpreting scientific results um from their studies I get excited anytime I
get to operate aope and so I really enjoy it when other people get to have that same opportunity and that same
learning [Music]
[Music]
process [Music]
[Music] well hello everyone this is Scott Roberts from explore scientific and the
explore Alliance and welcome to the 144th Global star party uh I'm here with
uh David Levy uh who is um uh trying to get focused in here from his his place
out in California and uh David are you with us yes I am okay okay here we go
there we go yeah anyhow um it's uh the theme tonight
is detection and and uh this is something that uh Thrills every
astronomer when they find that elusive object they've been going after um uh
and some of these detections of course involve just uh straight up discoveries
and um so um and on David is currently
uh spending some time with Jean Mueller who's made uh well over a hundred
detections of Supernova um asteroids comets and uh and
then of course David himself has made so many discoveries of of comets and asteroids as well I think he's probably
got a couple of supernova under his belt as well so um but uh David thanks for
coming on and doing this with me and uh spending I know that you're supposed to be um spending time with Jean right now
but uh uh thanks for uh uh L in from California well thank you can you all
hear me I um I you couldn't have
chosen a better theme than detections for this week because I have here Jean
Mueller at her home in uh just North of San Diego and um we're just having a
wonderful catchup visit Gan Mueller is one of the most famous and wellknown
astronomers in the world in the world that's right Jean has discovered
107 Supernova or detected as as the theme of
today is one of the nicest people in the world too
so and she's one of the nicest people in the world and my one of my very best
friends my friend for life that's right and uh I really so wish there was a way
we could get her out to see the eclipse but but um but but uh in
absence that I'm having a lovely lovely visit
with her my quotation today I also have to do from memory because I left my book
of quotations at home and so what I am going to do
is my favorite one of all of the quotations and that is Gerard Manley
Hopkins those of you who have studied oh yeah we have another visitor today and
that is James cat who is here and he may well want to eat this telephone if he
doesn't like what I'm saying but um if she for those of us who have taken jard
Manley Hopkins in high school or in college one of the most boring poets you
can imagine he has the rhyme scheme that is so difficult that you can't even follow it it's uh and and uh and his
poems are almost impossible to interpret very very difficult and the best part of doing Hopkins is when you go to another
poet except when Gerard Manley Hopkins was an undergraduate student at balal
College at Oxford in England and while he was an undergraduate he wrote a poem
about a comet and it is has so much heart and so
much soul to it I wanted to share it with you today I am like a slip of comet scarce worth
Discovery in some Corners seem Bridging the Slender difference of two stars come
out of space or Suddenly engendered by heavy heavy elements for no man
knows but when she CES the and Spins her skirts out while her Central Star shakes
its cocooning Mists and so she comes to fields of
light millions of traveling Rays Pierce her she fangs upon the flame cased sun
which today by the way has a big group of very active spots just coming on a
group that's almost the size of Jupiter and it's going to be a big one uh but
that's not part of the poem millions of traveling racep sure PL
sun and the sun's white as full as Gideon's
fleece but then her tether calls her she falls off and as she dwindles sheds her
smoke of gold amidst the sistering planets and then goes out into the
cavernous dark so I go out my little sweet is done I have drawn heat from
this contagious son do not ungentle death now forth I run I'm feeling that
the dedication to Gene of This Global Star Party of detections especially in honor
of the master detector of 107 supern noi
comets asteroids and a love of the night sky that is second to none and thank you all
very much for allowing me to share this time with you thank you so much David
that's wonderful and again happy birthday to you Jean Mueller I know that you're back there and uh um David thanks
for for uh uh coming in at this time so all right okay so that's that's
wonderful um we are um uh our schedule's
a little uh mixed up at this point but uh I think what we're going to do is um
we're going to bring uh I had John Goss on uh John Goss is with the astronomical
League um and his uh his talk is about
Mercury so John you are you're up next here well thank you thank you Scott
thank you um thank you yeah thanks for having me on I mean this is a certainly
a privilege for for me to get up here and talk about stuff that makes it sound like I know what I'm talking about but
we'll see how that goes You do know you're talking about well so sort of you know with the whole idea of detection
that that's kind of what it's about and we all want to see things um in fact we
all see them in different ways and that's how I'm going to start out um with my little talk here a number of
years ago uh my my wife and I were uh listening to the radio while we
were driving leaving uh a major city major US city and on the radio uh a
report um a night sky report by a local amateur astronomer and you know how how
these things go they talk about oh these are certain planets you can see you know at right after Sunset you'll see Jupiter
High in the high in the west or or high in the East wherever you'll see Saturn
the moon's going to be up that type stuff so there he was talking about it and he said Oh and before I forget that
bright object you see next to the Eastern excuse me the Western Horizon is Mercury
and I started thinking no wait a minute here I I was kind of following Mercury um out out of another another
interest and I knew that mercury was not going to be a bright object low in the west it was going to be there yes but uh
it was going to look look fairly dim so my wife and I were talking back and forth about this well you know I better
check up to make sure that I'm I'm not an error here so when we finally get home I looked at my records notes and
all this and I could see that uh that we were both right in a sense in a sense you see uh
what he what what the report was was talking about was the um published
magnetude of mercury was going to be fairly bright huh was going to be let's say uh 0 point plus 0.5
magnitude now for those of you who are unfamiliar with how magnitudes are well this is about equal to the bright star
uh prion uh favorite in the winter sky and it's easy to see it's one of the brighter Stars so yeah you could say it
was a bright object but since Mercury even though it was
about as bright as f um it was sitting fairly low in the west right after Sunset so that means it
was sitting in the brightest portion of the Twilight and you have a 05 magnitude
object in the bright Twilight it makes it tough to see really really hard to see you have to know exactly where where
you're looking and if it gets any dimmer than that you just can't can't can't do
it so um I'm G turn on my slides here I
hope show you how that goes so we found this excuse
me um so as I said we we we found mercury in in in the West but I I found
it as being rather dim and you really had a hard time seeing it although the published values indicated it being 05
uh maybe not even quite as bright as five but certainly that is is easy enough easy enough to see so I I I was
did some studies over the next few weeks of of mercury in fact even longer than
that over many many uh different apparitions many passings of the planet so I I get this down right I wanted to
see how well you could see Mercury under these published brightness uh mag
magnitudes and what I found out after many observations I was measuring it uh
um after so many minutes after Sunset after the sun has dropped so far below the Horizon um that uh measuring Mercury how
far it was above the Horizon and its pish magnitude and this is what I came to
conclude that if if you have uh a little to no Haze near near near the Horizon if
you wait until 40 minutes after Sunset the sun will be about 8° below the
Horizon Mercury if Mercury is 8 degrees or higher above the Horizon and if its
magnitude is brighter now this is I kind of messed this this this statement up but if the
if if the magnitude of mercury is brighter than 0.5 you ought to be able to see it but if it's less than 0.5 you
won't be able to see it and this is after many different observations I made
now back up again I can say 30 minutes after Sunset if the Sun is uh Sun would be about six degrees below the Horizon
and if Mercury is six degrees or higher above the Horizon if Mercury is Brighter
Than Zero magnitude which as you know is a fairly bright that'd be a fairly bright star if it was a star you can see
it so um this is from my own direct observations so I I put things together
in a chart here for you oh before I move on to that I also came to the conclusion that it really helps that if Mercury is
positioned somewhat above the ecliptic this would put a better viewing for um
northern hemisphere viewings in the springtime which is where we're at now uh it it would help even more if
Mercury was near as app helon but that really only occurs for viewers in the
southern hemisphere in their um spring sky this year I think that's going to be
sometime in November but anyway be that as it may put all this information together
what I was just saying and I came up with a chart like this and I threw in the dates for this
spring this is one reason why I really wanted to be on the global star party tonight is because this whole Mercury
apparation begins right now even though you won't be able to see it
tonight a few weeks ago February 28th Mercury was Superior conjunction meaning
that it was behind the Sun from where we are on earth so obviously you can't see it but over the next week week and a
half or so it swings out from the Sun and yes you might be able to see it if you knew exactly where to look and if
you had binoculus you might able to pick it out in the in the in the low Twilight this this low bright Twilight
that' be one to two weeks after Superior conjunction no Mercury at that point in its
orbit excuse me appears as a small pretty fat gibbus
phase and that's good because the gibbus phase um reflects a lot more sunlight
than a crescent phase so some of the published magnitudes are going to be
listing Mercury is being like minus uh 0.5 or so pretty bright and so that's
why you might be able to see it in the Twilight in the low Twilight let's move on a little bit so
then three weeks after the conjunction which is kind of where we're going to be at next week week um Mercury is still in
the gibbus phase but it's a thinning gibbus it's not really quite as bright but now it's higher in the darker part
of the Twilight and you'll be able to see it really easily and that's the time when people really look at it really
notice it is um when it's about 3 weeks after Superior
conjunction then about four weeks after Superior conjunction on March 24th remember it was behind the sun on
February 28th so four weeks later about March 24th is as far as it's going to
get from the Sun angular wise angle wise and it's still fairly easy to spot but
then as it swings closer to us as it starts coming between us and the sun it gets into that Crescent phase excuse me
yeah Crescent phase which doesn't reflect as much light as that Gib us and it dims significantly even though it's
still fairly high in the evening Twilight it dims significantly and it's tough to
see this year it uh the greatest Eastern elongation is on March 24th uh 3 4 5
days later it'll be tough to see all of a sudden it be like it's gone and this magnitude will have dropped whereas at
at greatest elongation it may it may be like a zero magnitude somewhere in there
but now four days later it's it's dimmer than a 05 magnitude and it's tough to see it's dropping back into the evening
bright evening Twilight see a little bit better here on
on on how you can see compare the two where Mercury actually is in it in its orbit we start out position number one
on the on the chart to your right now Mercury is behind the Sun as viewed from the earth on February 28th well as Earth
orbit the sun well so does mercury a lot faster and it starts catching up so when
it's in that bright gibbus phase is in this green section here that would be around March 15th or
so uh and then on March 24th Earth be there Mercury there and it be the widest
angle from the Sun then after that the uh angle between the Sun and uh Mercury
decreases quickly substantially and it starts to dim rather dramatically so it's tough to
see so how I started out with this whole whole talk was was um that that the the
car ride listening to to the report and where Mercury was well at that point on that situation Mercury was low in the
sky uh position low in the sky but it was still fairly bright because it was that gibbus face but it was in that
bright evening Twilight so it was tough to see so in a sense we were both right
I said it couldn't be seen easily that's true because it was in the bright Twilight that he said it was a a bright
uh object in the sky and that was that could be construed as being true because it was that bright giv us face some
something to think about there you know uh we see things in different different ways and uh report them in different ways but when you look into it you find
more about this if you talk about detecting Mercury for the first time and how long that you can see it in the sky
to detect it well this helps explain some of that what's going
on okay I just toss in there to talk about
the southern hemisphere because I don't want to leave this out leave them out because this is the global Star
Party unfortunately for them right now that the angle of the ecliptic with the Horizon is fairly uh uh low so Mercury
will not be uh Rising very high in the sky on March 24th well it's nice and high for us here in the northern
hemisphere southern hemisphere no it's low this is a horrible time to look at it but they got us beat this coming
November our Mercury will be much higher in the in the sky than than what we're going to see this march here in the
northern hemisphere they got us beat
in January January 88th of this year we had a really good
site in the morning sky in the East excuse me we had the Crescent Moon
very very pretty uh hovering right next to Red anes now how you like this this phone of mine that I captured this
picture really pulled out the red and darus isn't quite that red in the sky but you have the bright moon next to
Antares and then to their upper right excuse me upper left with very bright
Venus and to the upper right you can see the three stars of the um claws of of
Scorpius pretty pretty amazing and that's what a lot of people were were looking at but if you were look closer
at this spend some time in then looking in the sky you would have seen a very bright object low in the in in the East
or Southeast just above that bank of clouds that is Mercury and it that was about middle
brightness that it's going to achieve at least at least for this run around the Sun but as you can see if it would have
been lost a little bit lower in in in the sky it would have been bumping into those clouds and we wouldn't been able
to see it so to see the planet see it well you got to have a nice clear skies
a fairly uh low Horizon there's no no Hills mountains trees in the way and
then you might be able to see it if the conditions are just right now that's I'm going to leave you
with this so uh thank you for listening to this over this next few weeks go out
and see if you can find the planet uh especially after March uh 15th or so the
20th that's a great time to go out and see if you can find Mercury and when you do when you do you're going to be
thinking what what's all this Holo about you know of course I could see it it's so obvious um but come back a week and a
half later and it'll be gone or nearly so and you you you'll know what we're all talking
about so thank thank you for that Scott thanks thanks for letting me present something like this uh it's all a matter
of detection of your own personal experience with your own eyes right
right uh how many times have you seen um a Mercury well in a way I kind of make it
a little game because it comes around the Sun so often it's it's here for a few weeks and then it's gone and you
don't see it for a while and then boom it's back again and all this so if I'm if I'm at a star party or if I'm out
just observing by myself I'll I'll make a um a special point to find it yeah so
uh being absolutely honest I've only seen it like three times myself um but I think a lot of people
really haven't seen it you know it because you have to be in the right place at the right time in the sky
conditions and then it's like I said you'll be thinking you know what's the big deal it's easy to see well yeah
really a pleasure though is that you always see it in you always see it in Phase you know so um you know and it's
it's uh it's beautiful and it's to me it's you just get a special feeling
knowing that you're looking at the first planet in our solar system so and the
smallest the smallest planet too that's right that's right well thank you Scott
thank you so much John take care okay well up next um uh we are
going to be talking with Dr Ariel Grabowski she is involved with
unistellar citizen science uh program uh and she's going to give us an update
about that but she also is a uh uh I think a postdoc at the seti the search
for extra extraterrestrial intelligence program out there in California um and um so you know it's
always exciting to hear from someone that's uh working with those uh um those
projects and uh but I think her specialty and what she's concentrated on
right now is comets is that right that's right yes great right well thanks for
coming on to Global star party and uh informing us of of uh unistellar citizen
science program we like to get updates about that um uh unistellar has really I
think out of all the people in including ourselves um uh we don't uh the
telescope manufacturers typically don't have a formalized citizen Science
Program there's there's citizen science D with all of our telescopes but uh I
think only unistellar has this program and it's very special so what is your role there Ariel yeah um it's been
really fun working with them for that reason it's a really unique program that they have going on and so for them I
specifically run their Comet program there are are several programs that they have but I decide what comets we're
going to look at and that we're going to prioritize and stuff like that okay all right well I'll let you take it away
thanks for coming on yeah okay let's see let's share my screen here
here here we go okay yes so again I'm Ariel gregowski I am a postto at the SEI
Institute and I um also am an astronomer with unistellar um and today I'm going
to talk specifically about my work with the comet program um in unistellar and
the citizen science that we do so just briefly for those who haven't heard of unisell at all they are a
French company that makes these smart telescopes called EV Scopes um that you
control with an app on your phone and the point is it's supposed to be really easy to use um and if you have one of
these EV Scopes then you can participate in citizen science and so we have several programs comets the one I run um
but my colleagues also run the transient program which is like Supernova exoplanets occultations and planetary
defense um so there's a lot of different ways to get involved um if you have one of these scopes at
unisell uh and it's been really fun so far there's over 10,000 Eevee Scopes across the world everywhere around the
world at this point uh something we like to say a lot is the Sun never sets on unistellar and it's a really powerful
tool for science uh because we always have somebody who can look at the sky if
anything happens that's interesting if it's daytime where I am I'll message somebody on the other side of the world
and say hey can you take a look at such and such object and so that's been a really amazing tool um and so here I
just have kind of a map of about where the telescopes are located and the different models of e Scopes that um
exist which you can take a look at more closely on their website but um right now I just want to talk mostly about the
citizen science we've done in the comet program specifically um and so our goal
with the comet program is kind of twofold our main primary goal is to monitor comets over time now the reason
we want to do this is because comets are always changing they have these iconic
coma and Tails that is what you might think of when you think of a comet um and those are getting brighter and
they're becoming more active as a comet gets closer to the Sun and then conversely as it gets farther from the
Sun um this activity can fade um it's largely due to the um it being heated up
by the heat of the sun of course um and so we have a really great tool the
unistellar network to do this monitoring and to monitor a lot so over the course of a
week we could get a lot of measurements but also over a long period of time um so some of our goals with unisell is to
sort of automate this process where we take that monitoring and we predict
what's going to happen next um and we want to be able to do it for all different kinds of comets faint and
bright um and we want to monitor them for as long as we possibly can that's
going to really help us with the prediction and so it's important that we can detect comets at their faintest
possible point in their orbit um and so that's something that we've uh recently
been able to Define and so I'll share a bit of that um but we also are really well equipped to identify something
surprising that happens in the sky so if a comet outbursts for example um which is when it gets really bright all of a
sudden um that is inherently serendipitous process um we
just hope to catch it right and so our network has been really really good at a following up with alers whenever they're
reported by the astronomy Community um and that's been really great but now we
want to be able to uh do this even faster and monitor more and automate
this monitoring and detection process so nisell can be amongst the first
to discover an outburst and share it with the community instead of just following up um and so we've we've done
a lot and we're making a lot of strides in this detection Department um and in particular I'm
going to talk about one Comet that's coming up to be a very exciting one this fall and that's Comet c2023 A3 suchin
Chan Atlas uh excuse me if I did not pronounce that correctly um but this
comet is exciting because it's going to be a naked eye comet in the fall um and
basically when this Comet was discovered which was January of last year it was very very faint it's actually still
pretty faint um but it was very faint and our e Scopes didn't weren't capable of seeing it at least I didn't think so
and that I started getting jealous of other people observing this Comet um and
reporting that this is going to be a bright one later I wanted to get in on that I want to start you know honing our
pipeline so we can make the prediction ourselves as well um and so I decided to
reach out to our Network and say hey I know that we don't think we can observe a comet this faint um but can we try
anyway um and somebody did and it was there and so this is the picture of that
first detection that we had with an E scope of this Comet which was in April
of last year um so a few months after it was discovered and before I thought we'd
be able to and so we really we learned the capabilities of our EV Scopes to
detect comets earlier than we thought so this is at a really faint magnitude um that we just didn't think we could see
but now that we know we can we can start monitoring these comets even sooner and our predictions can be even better um
but yeah that's the comment right in the middle it's hard to see but that's that's the
guy so what we can do with this information is plot how bright it is over time so that's what this plot is
all those data points come from different EV scopes um and you could see that cluster is
pretty you know um scattered around and that's because the comet was really faint there um and so that means you get
a lot more scatter a lot more error in your measurements and then as the comic got brighter you can see the dots are
more clustered on our prediction line so we just have a little less scatter as things get easier as it gets brighter um
but this is showing something very exciting and that is a peak magnitude of around negative one and the the
projections across the board have been negative one0 which is very bright it's easily naked
eye um so this is exciting so this it'll be coming to parah helan and closest
approach to Earth between September 27th and um October 12th so that'll be the
time where this comet's at its brightest and at this time there's some good news and bad news uh the good news we'll start with
is this weird concept called forward scattering um and so basically this is the idea
that the comet is going to be so close to the Sun uh when it's at parhelion that it will be between the Earth and
the Sun in its orbit uh and so we'll get this weird sort of back lit Comet like
if you um are driving on the highway um and the Sun is setting in front of you
and there's you have like a bit of dust on the road you might notice this effect as well and what's happening here uh is
that the the sun is hitting the dust particles that are in that iconic tail of a comet and they're doing this weird
thing where the particles will scatter the light away when the light hits it but they preferentially scatter the
light forward and so as the angle gets you closer and closer between the Earth
and the Sun this effect becomes apparently more obvious um but what this H what happens is the comet is so bright
but the light's being scattered even more so it looks even Rider so not only is it going to already be a very very
obviously naked eye object it might be even more so we've seen something like this in the past with Comet mcnut so
that's this picture here and this is what I showed in the beginning um it might be a good parallel to what we're
going to see with C 2023 A3 um but in 2007 this Comet showed a lot of forward
scattering so it was predicted to be around -2 which is still brighter than
what we predict A3 to be um but it ended up being 5.5 or -6 and that's that's a
lot brighter and so we can expect something like a maybe three to four
magnitude increase maybe again comets will do what they want and we're just
going to have to wait and see how much dust this thing really produces and how it's going to scatter this light how
much gas it has versus that dust there's all these factors that could change things but um this just shows that it's
going to be brighter than we thought and it could produce something as beautiful as comic MCN did in
2007 comic mcnut was even seen during the day so that's what I have circled there during his parah helan time it's
hard to see but you could see it which is amazing the sun is still out um and
this kind of gets me into the bad news with A3 is that it is going to be uh
visually close to the sun when it's this bright um so you're going to have to really be chasing it catching it um as
the Sun is setting or right as the sun is rising um rather than looking at it in the middle of the night um depending
on the time so that that's going to make it extra challenging it's going to make it look a little fainter because the
sunlight will kind of block some of the Comet light in a
way um but you know the mix of these two effects I think it's going to be a worthwhile object to Chase and try to
find and this fall and then I just wanted to end on what it's looking like
now so this is just a little report that you might get back um if You observe with
unistellar um once you upload your data we go through an automatic process that
just prints out these little reports so we could see what's going on and this is where I get my data points to put into
that light curve I showed you um but so this also shows you a little picture of the Target that you're looking at so
right in the center of that little picture is comma A3 so it's still looking a little bit small a little bit
faint um but it is there and it is brighter it's uh it's an obvious dot in
the center of the that picture so that's kind of good news but it's only going to get brighter so we're just going to keep
monitoring it with the network and we're going to see what happens in the fall So yeah thank you that's it for me
wonderful yes how exciting I mean uh you know uh the capturing uh a comet really
faint U you know beyond the limits of the unistellar uh or what was thought was
the limits of the unistellar is uh is uh very uh promising there's a lot of um
amateur astronomers that I have talked to about uh you know what kind of
Citizen science do they do and sadly many of them don't get involved in a
citizen Science Program um but uh you know unistellar
makes it easy to do and and uh and the results that you get back are exciting
and you feel like um you know that you're really contributing to science so
it's um um you know I think the perfect
accessory for anyone that's uh you know uh thinks that they are a serious
amateur yeah definitely and I'll also say just selfishly as a scientist I
really have been loving having this network of telescopes everywhere um in
grad school I would apply for telescope time and I'd get it sometimes you know um but now I'm getting telescope data
every single day and it it's just been really fun to utilize it's been a lot of
data really really uh wonderful I've been able to do projects I would have never been able to do so I'm just as
grateful for the citizen science aspect as hopefully the citizen scientists are as well oh I'm sure I'm sure um Ben
Cross weight is uh watching I think from Australia this morning or his morning anyways uh on Facebook and he says he
read there's a comet or a meteor coming very close to Earth in 2028 and he said supposedly it will pass
under the satellites and he says who's monitoring that so so if it's an asteroid that's
our planetary defense department so I'll have to ask that colleague of mine what's going on in
2028 right yeah so uh Ben maybe you
should get involved in watching that you know so yeah if it's going to do something crazy I'd love to monitor that
and see what happens sure sure well thank you so much again Ariel and uh we
look forward to seeing you on again on global Star Party take care yeah thank you okay all right so um uh up next uh
we have Robert Reeves uh to talk about uh uh lunar terrain and um uh I'm very
excited to have him come on to uh to the 144th Global star party let's give the
spotlight to you here Robert there we go all righty well in my face okay uh well
good thing I took a shower after I worked uh today U putting up a bunch of sighting uh uh anyway um the theme of um
detection um I tried to apply that of the moon so uh um what uh how do I
interpret that the detection of finer and finer details perhaps what can the amateur astronomer see on some fairly
common Targets on the moon that um um needs a little bit of extra look um
finding finding some details on some common targets so um um I'm going to
scale my Approach To The Moon in that direction today and uh of course as
usual saying that uh if you enjoy what I talk about on the moon um remember
there's plenty more where that came from in my book exploring the moon with
Robert Reeves available on Amazon and uh just do a title search exploring the
moon with Robert Reeves and there it'll be can be on your doorstep in two days
so let's um try the great screen share experiment and uh see if my title slide
comes up do we have postcards from the Moon showing yes you do oh good well
that means we're halfway there all righty so today um looking at
some of the uh common objects on the moon um we look up at the full moon and we see the uh the the the Mario that
make the face of the Man in the Moon the uh of the Mario embrium making the left
eye and um serenus and tranquilatus making the the right eye and uh
various features making the nose and kind of a offset smile but then you put a telescope on the moon and you start
looking it the smaller and smaller details and the novice sometimes gets
lost I mean all these these details crowding into an eyepiece it's not like looking at a a single Galaxy in an
eyepiece or a single planet uh you've got this crowd of details so um uh in
time the obser lunar Observer learns to pick and choose and U look at specific
targets and zero in on on particular details on them so uh let's move on to
the next slide and see the very first one uh thinking about uh um um detection
detecting things that are normally invisible uh in this case uh we're
looking at the Western Mar tranquilatus just above the Apollo 11 landing area
and and we see excuse me we see a feature that is
normally pardon me too much sawdust today uh we see a feature that is
normally unseen because it it only shows up during Sunrise Shadows uh right at
Sunrise or at Sunset and I'm talking about moving up one more slide um the
ghost crater Lamont uh notice the uh ringed cir C
feature uh surrounded by yet another ring outside of it and then a number of wrinkle ridges that progress North and
South this gives it the appearance of a a lunar spider uh but Lamont itself um
substantial crater that formed on the um tranquilatus Basin before the lava
flooding that paved it over and uh turned it into a dark marot so that
crater got buried underneath lava flows but we can still see where it was by the
uh the rim of the crater uh pushing up the basalt and making these ridges
circular ridges so we see Lamont in the center and we notice that there's also a
a second ring surrounding it particularly of the South so U nowadays our interpretation is that Lamont is not
just a ghost crater but a go small ghost basin uh so we used to think that basins
were a any crater over 300 kilm in diameter but now that definition of a basin is
getting flexible we're uh finding features smaller than 300 kilometers
that have distinctive features of a basin particularly multiple impact rings so now Lamont has um evolved into a
ghost Basin but like I said you can only see it for maybe one or two days a month
because after the sunrise Shadows uh after the sun rises higher the sunrise Shadows go away and these very shallow
ridges that allow us to see Lamont by the the sunrise Shadows uh they're
they're very very low they not more than a couple hundred meters high so the Shadows disappear when the sun is
overhead you can't see Lamont at all it basically vanishes so moving on to another sneaky
little Target that uh you can only see one day a month now this is one of the
largest mountain ranges on the moon the Corda mountain range U which is actually
the outer impact ring surrounding Mari Oriental on the Far Western limb of the
Moon uh we don't see the entirety of Oriental because it overlaps onto the Far Side of the Moon but we we see it
just nestled up next to the ri the limb of the moon and the um
uh outer impact rings of it arcing around the near Side of the Moon uh form
the Cordillera mountains which we see here uh the mountain range that has the
shadow behind them and then you look up toward the uh the uh The Horizon the
limb of the Moon and you see the Shadows being cast by yet another mountain range
the outer Rook mountains well actually they're they're called The Rook mountains but we um traditionally in the
outer Rook because right on the horizon we see the sun just kissing the uh the
rim of the inner Rook mountains now that's an unofficial name that mountain
range which is the inner impact Basin uh Basin impact ring around Mario Oriental doesn't have an
official name so we unofficially call it the inner Rooks and uh The Rook
mountains in between that and the cordas uh we um expand the name a little bit
instead of calling just the Rooks they're the outer Rooks but let's get a little bit closer
here and uh look at the cordas um they they span hundreds of miles and here
we're looking at the southern part of it um um Mor Oriental is on the western
limb of the moon but in order to show it easier on a computer screen I have turned it sideways it's uh um it's
flipped over on its side the West is up in this View and uh we see the Shadows
being cast by the uh the Corda range now the trick is let's go to the next slide
and you'll see the the northern part of them uh you still see that shadow casting behind the the mountain range
allowing us to see it now bear in mind up until about 13 days um after New Moon
um the far limb of the Moon Western limb is still in Shadow the uh phase of the
moon hasn't reached that part yet it's still in darkness then about 13 days after New
Moon the the sunrise reaches the cordel A and The Rook mountains and they are
casting a shadow and we can see them the the relief created by the Shadows but
one day later during the full Moon the Moon is very flatly illuminated and we
can't see those Shadows anymore the Shadows are gone so the rook and the cordas
disappear we can see them just that one day a month so uh um another detail
detection you can only um see it at certain times so um you have to time
your um your approach carefully about 13 days after New Moon you'll be able to see these 14 days after New Moon which
is technically full moon they're gone we can't see them anymore
so moving on to another one another thing that happens quickly on the moon
and you got to got to um keep an eye out for it and uh and watch it as it happens
the span of three C the the span of four images of sunrise on tus occurred over a
period of only two hours but look at the tremendous change in the appearance of
the floor of tus as the sun just kisses it you see the Shadows uh streaking over
from from the the rim of U tus crater
and then as the sun creeps up higher after about 20 30 minutes the Shadows have noticeably shrunk another hour goes
by or an hour goes by and uh now we're seeing most of the floor and uh as we
approach two hours into this sequence we begin to see features inside the floor
of t crater uh we're also observing uh another curious effect that doesn't last
very long just several hours so you got to go to uh watch just at Sunrise it's
in it's called the Clare obscure effect that's where the Bulge of a crater floor
a large crater bulges up into the sunrise uh this we can see the center of
the crater being illuminated by the sun before the outer area the outer portion
of the floor of the crater receives sunrise and this is because the Moon is much smaller than the earth it's only
only 2,000 miles in diameter so the curvature of the moon is much greater than the Earth's curvature so the uh the
Bulge of the curvature of the Moon um protruding up the center of a large
crater Flora is much more pronounced than it would be on earth so uh we we
get this effect where the Cent of the crater sees sunlight first long before
the outer floor uh receives sunlight simply because the the the crater floor
is bulged up so much and again that that effect is called the clar Obscure effect
we can see that on a number of craters on the moon but it's it's quite uh prominent on tus and tus is almost dead
Square in the center of the Moon a very popular Target during the first quarter
moon so poke along a little bit here um another very popular Target that has
additional details that uh U you should examine the arist Arcus Plateau up on
Northern Oceanus procerum um well kind of zero in on it easily with a modest power eyepiece
because the the bright Ray structure splashed out from arar's crater down at the lower uh lower right hand corner the
Southeastern corner of this elevated volcanic PL plau but um you look care
carefully around the region uh just off to the west of araris plateau we see the
ghost crater Prince partially buried uh the southern part of it is completely
paved over with procerum lavas only the uh the northern rim of it protruding up
and then above it notice the Pitchfork shaped reels flowing northward uh at the
same time we see Prince crater is tipped to the South so uh uh because the
southern part of it it's buried so there's a high point right along the northern rim of a of a prince crater
because those volcanic rules are flowing North they have to be flowing downhill and yet Prince crater is tipped to the
South and uh in the same region notice the little mountain peaks Pro protruding up uh just uh U up and around the uh ryr
Prince complex there um we call those the The Harbinger mountains and that is
simply because when sunlight or Sunrise reaches these particular mountains it is
the harbinger of sunrise on the Aeros starus Plateau so let's zoom in on the plateau
a little bit and uh look at Schroeder's Valley the uh the hook shaped re flowing
upward and to the West this is the one of the largest sinuous reels on the moon
uh this flowed molten lava hundreds of cubic kilometers of
molten lava flowed down this R and uh emptied out onto ocean as Pro Arab uh
the volcanic fire fountains spraying Ash U up from the U volcanic pit that fed
this this real fed it this molten lava dusted the entire plateau and gave it a
a slightly different shade of color than the surrounding uh Maria so you look at
aristar Plateau many people see it as with a very definite yellowish stinge um
but uh it it it clearly appears darker even if uh you're partially colorblind
so uh lots of U interesting features in this area U uh the U Plateau itself
volcanically elevated and uh pushed up by uh uh the volcanism on
the entire region of the U Oceanus
prum and let's uh sneak up a little further here uh more volcanism but um
evidence that you can see that uh there's been relatively recent volcanism
on the moon I I've spoken about this this before the uh the volcanic vents on
aristar I mean on um um alonsus crater too many A's uh
alonsus crater in this case um the the crater immediately south of tus that we
were looking at earlier with the with the the sunrise sequence but um um as
I've mentioned before uh the the vulcanism of this is very intriguing because we are under the assumption that
volcanism on the moon died out about oh a billi billion billion and a half years ago but here we've got definite pockets
of volcanic ash splashed on the moon uh look on the inside of um of alonsus at
9:00 at 3:00 down at 5:30 position and you can see these dark ash deposits just
with a very modest telescope now I am under the
theory that Ash deposits dark ash deposits on the moon will be erased in
time very similar to how crater rays are erased by the ongoing churning of the
Surface by uh meteoroid impacts so um we call this the gardening gardening of the
surface where meteorite impacts continuously till the soil and turn it over and that will eventually erase
bright crater Rays on the other hand it should also erase dark ash deposits so
uh here we've got these very dark obvious deposits uh indicating something
must have happened fairly recently on the moon volcanically on the moon so
still a bit of a mystery we haven't seen any active volcanism on the moon U
recently but um back in 1958 U Nikolai kerev um took
spectrograms of this area and observed a a strange spectral response of the area
that was convincing enough that uh back in 1965 NASA sent the Ranger 9
spacecraft to crash land in alonsus and look for potential volcanism in the
region uh didn't find any we haven't seen any sense but obviously something has happened in alonsus volcanically uh
in the past less than billion years so looking at other details
uh features that I really love are floor fractured craters uh these are craters
that started out like an ordinary complex crater like cernus for instance
had a central Peak had the collapse Terrace walls that descend down into the crater uh a series of
stairsteps but uh if this crater happened to form near a volcanically
active Maria uh the impact shock that you shattered the crust underneath the
crater um provided conduits for subterranean uh magma Chambers to feed
lava up to the inside of the crater so it welded up in uh into the crater floor
from within it pushed the crater floor up and paved it over with B salt and as
it pushed it up it creates these fractures so posidonius we see is uh U
got quite a few reels crisscrossing around it uh the uh Western one is
particularly intriguing because it's not just fairly straight when you look at it
under high power and and a really good seeing uh it's is very squiggly almost
almost like a coil spring stretched out so it's it's a very fascinating feature if you uh take the time to look at it uh
when the seeing is really good uh another area that deserves
attention and um um um examine ation of finer detail detecting finer detail um
Plato crater on the Northern shore of Mari embrium and the Alpine Valley U
stretching across the Alps mountains now when we were um kids and just beginning
to really enjoy the moon back at the dawn of the space age uh the floor of Plato looked flat black featureless and
uh the Alpine Valley was just this scar through the uh the uh the Alps mountains
we did not telescopically see uh additional detail but today uh we look
at Plato crater we clearly see multiple small impacts on it now if you can see
four or five of these small impact craters on the floor of Plato you've got some really good seeing going on it
doesn't take a spectacular telescope to see this but it does take good seeing so
the the image is calm and not quivering uh the same with the Alpine Valley uh
back in the day we had no clue that that real ran down the middle of the Alpine
Valley we couldn't see it it was we were blind to it uh we didn't know it was
there uh the seaing was usually bad enough that we couldn't resolve it because it's only about 500 meters wide
but it stretches the entire length uh more than 100 kilometers of the Alpine Valley nowadays um it's it's become a
Target to test your uh your seeing and the resolution of your of your lunar
astrophotography U if I don't detect the r running down the middle of the Alpine Valley I essentially junk the picture
because it's not good enough uh another of the oatmeal cookie
craters as I call them the uh floor factured crater um gassendi on the
Northern shore of Mari humorum another volcanically modified crater in
this case we can still see some evidences of the Terrace walls we can
definitely see the central Peak but the floor of it been Vol heavily volcanically modified and got these
cracks and reels running all over it makes it look just like Grandma's oatmeal cookie right out of the
oven uh another real that uh deserves our attention rimus orales one of the
longest linear reels on the moon uh almost 400
kilometers long uh let's zoom in on a little bit and uh we can see it south of
ocean prum down in the southwestern quadrant of the Moon and uh a very
straight linear reel um of it's actually a volcanic feature um a sheet of magma
pushed up from the moon's core and thrust up to the crust through the crust and split the crust open but this sheet
of magma didn't erupt as a volcanic uh eruption so uh basically it split the
surface open the land collapsed between two parallel faults and created the real
now we could trace it up from the south working up through the North and see how the real uh fractures through
pre-existing craters and then we get up uh toward the top and we see those two
small fresh craters overlaying the uh The Reel so uh The Reel has been there a
long time it uh cut through pre-existing craters and then more recently it was
overlin by fresher craters and getting down toward the end
of things uh look at our uh one of our sentimental lunar favorites Tao crater
uh everybody can find Tao because its magnificent race system is I mean it stretches halfway across the face of the
moon during the full moon but at Sunrise Tao shows us a different feature
instead of seeing the ray structure at Sunrise uh we see thousands and
thousands of secondary craters uh let's zoom in a little bit here
and look at the region around Tao there are thousands of tiny tiny pits now Tao
formed about 108 million years ago and that's with an m not a be uh it's fairly
new it formed during the period when the Tyrannosaurus Rex was ruling the Earth
the flash that created Tao surely startled many a T-Rex here on Earth and
as the ejecta showered out of Tao it rain back down on the moon it created
these these secondary craters there literally thousands of them all around
the taer region um look a little further south and you can
see these secondary craters are spread all over the pre-existing craters that
had been there for U since almost since the moon began was was formed um the
region around Tao uh has craters that are up to 40 times older than Tao itself
and then here comes the young hitter Loper creates this blast of Buckshot that Rings back down on the moon and
just Peppers the whole region so one final look here at um U one of
our cinamon lunar favorites the straight wall the black linear feature um seen
casting a shadow at Sunrise it's it's it's a slope not not a not a classic
Cliff but uh as the sun rises this the steep slope casts a dark shadow in the
uh afternoon when the sun is high in the sky the this slope is brightly illuminated and becomes a white line but
what is Vis also visible in this uh image is something that uh we were again
blind to back in the uh early days of uh um telescopic lunar observation uh we
did not know that Ry Bert that uh curved
uh linear reel to the sinuous reel um to the west of straight wall we didn't even
know it was there um we'd look at the Moon it was quivering and shaking and the seeing was bad and we were happy to
see the straight wall but U that rhy of Bert eluded us it didn't become a viable
Target until the era of digital lunar photography where uh uh we could enhance
the view beyond what we can see visually and now Rama Bert is very much a uh uh a
Target that we seek out and uh verify that our our seeing and our focus is
good enough so uh uh another one of these targets that we didn't even know
about when I first started looking at the moon and now it's a very common Target uh just because we've educated
ourselves and gotten much better at knowing what we're looking at and uh that oops Yeah I was supposed
to zoom in on a little bit and uh give you a slightly better view of rabert but the if you can imagine
looking at the moon through our four and six inch reflectors that uh were pretty
substantial instruments back in the 1960s and uh the the atmosphere is
quivering and shaking and quivering and uh uh we can't see that uh Rima Bert but
we could see straight walls so we were we were happy campers but uh it's a whole new world for us now and uh I
always say say there is much to love on the moon and I always ask you to come out and join me on my playground and uh
enjoy what we see on the moon and uh I hope these uh little Clues have given
you something to uh to ponder and look a little deeper at the Moon not just at
the common Target but the other details that are nearby or even within the
target so uh there's a world of geology out there and it's available right in
your backyard the moon laughs at light pollution uh so uh you can observe the moon anytime it's
in the sky even if you're in the big city so uh let me stop my screen share
and uh I have enjoyed speaking to you once again about U the the subject that
I dearly love uh it's been a very busy time for me uh the uh last week I spoke
to the U local chapter of the American Chemical Society about the Moon tonight I'm talking to you tomorrow I address
the astronomy on top chapter here in San Antonio uh this Saturday I address the
public library next week I travel to Corpus Christie and a lecture at the
Museum of Natural History down there so um I I dearly enjoy talking about the
moon and I I hope a little bit of my passion for it rubs off on you it comes over loud and clear Robert it's awesome
so uh thank you so much for this present ation and uh you know and and for all
the um hard work you do in making such incredible lunar images you know that is
uh uh their second to none in my book so thank you thank you for uh participating
on another on another Global Star Party you've been on so many my pleasure so we
really appreciate it okay all right so we are going to move along uh and our
next speaker is Adrien Bradley Adrien I think was uh uh mixing bowling and uh
and astronomy again is that
right all right I found a me butd so if you were watching my little screen you
probably saw me throw a strike I am still in bowling league but I still want
to give a quick little presentation of uh Robert you're still on your
presentation inspired me because I'm going to share my uh phone
screen and let's see where is the share button there it is and I'm going to
share some photos let's see um
wrong pictures to share let me cancel that and share the right app
um I have a share screen that way okay so so Robert I pointed my
camera we the theme was humility and um you know looking up at
the heavens and it's something that um I've always
felt you know was a uh part of me enjoying the night SK just looking up at
it and sometimes I o shoot the moon you say it's in the backyard well this was
behind the bowling alley and I decided to just take a shot at the Moon did not
realize that I ended up capturing the Jura mountains which you're seeing in this
picture um which I'll try and zoom in yeah the juror mountains I caught a
moment that I've heard is known as the Golden Horn where the durur mountains
are lit but the uh sea of rains um is still in Shadow the Bay of
uh rainbows underneath which the Jura mountains at the top of the picture goes
so this was handheld with a camera and I know that there are folks who try and
get this exact image and I just simply aimed up and shot it so sometimes
Imaging can be you know luck or Providence however
it plays a role however humility also includes there are times when things
don't go so well and that's not one of the pictures things may not go well there
could be a lot of haze and a lot of clouds in the sky you know we like to show all these beautiful pictures but we
don't show the pictures all the time when and we tried to go and clouds
interrupted our night or clouds showed up or you know a lot of these
are you know this this picture was an example of I went out there and it was
absolutely raining so humility not only in looking up and
enjoying seeing things you don't normally see like upcoming Eclipse but
also the humility to know that sometimes especially if you live in an area like
Michigan clouds are a reality and you just have
to deal with it or do your best to um
deal with those clouds you know and when the moon like you know Robert all these moon photos
the spirit that Robert Reeves tells us the Moon is always there and even with a
600 mm lens and a decent uh camera now these Samsung
phones um my thought on it is if you have a beautiful picture and all of
those features are real it's a real photo it may not have been captured exactly like my DSLR camera captures it
or like Robert's equipment captures it but uh it might be there
so so I'm actually going to cut it short because I think it's my turn to bowl
again but I want everyone to know when you keep looking up you you may get the
shot that you intended but it's far better to get the shot you didn't intend I didn't intend to get Aurora but I just
aimed North and I tried and um when you're on this journey sometimes it's
about the surprises that the Universe gives you and you never know depending
on where you are what you might uncover you just have to keep shooting and find
out so with that I'm going to see if I can unshare and I'm going to turn the um
star party back over to you Scott okay and I'll be listening in of course muted
but I'll be listening in to the rest of the presentations that are going on keep looking up even if you're bowling get
out of the bowling center even if you're bowling hopefully when I get back there I'll throw another strike uh thank you
Scott I always enjoy being good luck on global star party thank you and have fun thank you okay all right so uh now we're
going to head on down south to uh Argentina uh where Caesar brolo is set
up on his um on his balcony here and uh
sesar how are you how are you good good let's uh let's add you on here to
um it's a clear night is uh it's great for for
astronomy uh maybe maybe first of uh the first subject that we can show live is a
classical or your nebula we can um Let me let me show you the my
screen
okay uh we are um fighting
together something that I need to to to change the position in my
screen is our our presentation uh because it's
over for next time maybe I need two two different
screens now perfect because sometimes you can see that I move the I move in
different [Music]
positions more than one second we are in the
area first of all something that you can see that I change is the the time of
exposition I need to use lower
gain and a lower Exposition now I change it to more
game for example tonight I don't have I don't
have a go to elimation
but as I have a a brly and much better
but than other times uh the position for for for the
polar alignment I can
I'll put in the nebula now in my
screen is the is the remember the time that that I show the
rainbow yes back yes yes it's back because it's
because I using but it's great it's something that
is very near to it's not the idea to to watch uh
to make a picture if
not first of all the line here is a reflection because it's a light very
near to a wiing actually the nebula is beside a wiing and a reflector in the
will need make this make this reflection but I use an
accessory that is not the best for for uh after photography because have a a
little little area of reflection but you can see that I'm I'm
um using the right okay
position for for the audience all that I make is
change this position okay this
gain and
having we are putting this the n in the center only the is watch the the nebula
with the colors and not in live image and not take the
picture and we are working okay
fastly because in few minutes more we are having six seconds okay and the game
it's
okay let's and we are going to have this a live
stack that is perfect for this kind of shows or you know
mhm Let Me
Clear okay is the nebula with the rainbows
colors because it's not the the right conditions it's the city it's the nebula
between two buildings with the windows with lights
but as say a few minutes
ago our friend about the hu the the
lucky that we are to to see something this great it's something that you were
Cesar if you were doing science Imaging absolutely this uh this this
kind of artifact would not matter you know you would uh you would ignore the
artifact and uh be looking just for the data you know itself so
um but uh nevertheless it's still beautiful and uh and you're doing it so
yes you are you are watching something in your screen that you're are taking
with your instrument and um in this time in this
time do you have something at maybe
15,000 years like years and two weldings between no more that 50 Ms and this is
something magic because uh you are
receiving a light from the universe from many many places in the universe um do
remember that for example sometimes in another part of the year in another time of the year in from the same buing I
have a time where I can uh I can take
the a Galaxy the the the Hat
Galaxy uh and this is Magic and this is not uh 15,000 years uh like years it's
much more it's about millions and disappears between your city between the
wildings and it's it's great it's something let me we can we can make
more um I finish that and we can make a
little more game look that something something that
uh that is matching we are watching the
how how the the nebula is
going in the back side of the will to have something of a
scale this is a is a vony of of the buing in front of
me simply is is about the scale of things and this size is no more
between this and this you don't have more uh diameter than the moon or the
Sun the scale of the things are very very interesting look that we are watching
the wheel we can change we can change it uh
to some Southern uh emere object I'm going to
this Southern Cross I'm going to put
less position more real life decision
more
gain look that it's
beautiful the telescope is tracking the nebula and it's not the will that is
moving is the you are watching the the
rotate the rotation of the of the of our planet simply watching a part
of the sky with a nebula right here and this is something that is is wrong for
to say okay it's not it's a bad picture okay but enjoy this moment sometimes
this kind of moment they say come on smashing come on that's
right yes he absolutely great John Ray John Ray is watching on Facebook right
now and he says uh he said that amazing circumstances you can overcome and still
obtain a good result keep going Caesar thank you and he also says I hope
it's not the building moving yes it's not the it's not the wind that that 100 m per hour win yeah
let me
uh put the to have more idea let
me rotate the
CCD okay because the welding is vertical okay to have idea to the
audience what
okay now actually the is is falling and going
to the to the West the the sky in this part and
falling and going to the
West let me rotate one
180° something that I love I can rotate that I don't I
don't okay to have the real position of the stars now I say yes
is the eclipse of a nebula fast wall fast Earth is turning here yes yes it's
something all is we sometimes we uh feel this like a
normal but it's so great that we can enjoy this single
things yeah now you have the the bright position the sky is falling to the to
the west and you as my telescope is
tracking the mod is tracking this Stars you are watching the the the wall of the
building the tower going to the East and
the north on up side it's great a question here um I
know where you are Cesar but NG astronomy watching on YouTube he says
where about in Argentina are you Cesar in buenosaires the capital city
it's a it's a city of uh around maybe 15
million people between the city and the metropolitan area very very very
big sometimes Maxi tell me that from his
City at 200 kilometers one 20 m
one 120 miles maybe even more he can see he can
see the bble of Life of woes yeah it's a huge population
absolutely and a huge amount of Life pollution 15, 618,000
people yes this year mhm we can try we can try
I don't know maybe if I'm lucky let me try if we can go to another
option maybe maybe some something of H for example the ah the remember the the
the CL the cluster that we saw last week I found the name the pair the pair it's
was a it's very interesting the cluster that we found last week I I when when we
I say the the cluster uh with a shade like a triangle
was very interesting but I don't remember I don't remember the remember the the name is the pair the the name of
the class last Friday last Friday uh we uh
Maxi and Nico we were together in a
Observatory of um of San Miguel was a great great experience we uh I I I
prefer next week next week uh that we present because how we have material we
took pictures um uh was we was so so happy to
to be together in a life person um and
was really really a nice experience I try the area
of of um Karina neula maybe
is it's too high for my balcony sorry that tonight was uh I am
not in the rooftop um sometimes for ETA Karina maybe maybe it's a
time that I need maybe wa a little more time but but in
the area OFA Karina maybe we can found another interesting clouds interesting
uh no clouds sorry I don't no I don't need clouds I say clusters
sorry I we I don't we don't we don't need to call to the to the
clouds yeah that's right well Karina is over is beside the
the the the roof of my balcony but but let me
um let me take a trip by I can change the
declination let me show you telescope where
is the light that you are you're watching is the is the
here here we got some stars now yes yes a lot of stuff it's a very rich area
this is more the area of of
vaa
look the the the quantity of
stars oh yeah I need maybe half hour more if you
have more presentations uh to have clear the Karina nebula um I I
can I can show you back yes yes no problem because it's clear it's clear
maybe in half maybe half hour no more um well I I
prepare another another uh lay view of this area
in uh after some presentations okay I enjoying uh the show
and okay I I yes I advise you by by
WhatsApp the when I am ready okay all right okay okay yeah all right thank you
thank you Scott we see you later thank you okay so now we will
um uh we will move across the planet to
uh Nepal uh to visit with deep te gatam
deep te are you available hello there we
go here we are am I AUD yes yeah D it's
been a long time since I've seen you how are you I'm good how are you oh good
very good is your family fine everything good
yeah everything is good just um uh I'm engag my stady and while the GSP is
running uh I think in the US is uh like central time it's uh the p.m. uh it's
like night time but in the Nepal it's the early morning and I have my classes early morning
oh no okay mhm so luckily uh today is
the some kind of like annal event of our department and it's going to be a little bit
late okay Al so like uh today when I see the
theme dediction uh like talking about like as We Gather under the like expans
expensive canvas of the night sky I deeply move by the the theme of detection uh that premes our said
passions for astronomy uh for me detection is uh not just a technical
Pursuit it's a profoundly human endeavor that ignites our curiosity FS our
imagination and connect us to the vastness of the cosmos uh in my journey as an astronomy Enthusiast I have had
the privilege of participating in asid SS campaign organized by International
astronomical SCE collaboration where we sarce the asteroids and uh I have a
three provisional Discovery um searching for this like uh old space wonders uh
left over from when our solar system started is really exciting and make you
feel small like it remind us to take care of Earth and learn about the danger these wandering rocks might bring but uh
they also have secrets that can help us to understand where uh we all come from
like it can demonstrate our own Origins but detection isn't just uh like about
the identifying object uh in the night sky uh it's about the delving in the
depth of unknown uh like peeling back of the layer of mystery uh that swore our
universe whether we studing the interact dance of distant galaxies or tracking
the trajectory of a near Earth asteroids is Discovery is a testament uh to human
igny and our uh like thought for knowledge uh as we G word uh let let not
like let us not forget that deeply personal aspect of detection astronomy
uh it's about the moment of quite contemplation as we Marvel at the beauty
of star uh like it's about the sense of Wonders that STS within us as we like
Ponder the vastness of space and the like uh nature of our existence uh in
the Stillness of a night sky with a star twinkling like a distant beckons of light we find ourself evolved in a
profound sense uh whether we are seasoned professional peering through observative telescopes or enthusiastic
like uh amateure gazing from our backers The Experience unites us in our R
reverance of the like a universe significance or magnificance like let us celebrate this theme of detection not
just as scientific parit uh but is a deeply human Endeavors let us honor the
Curiosity that drive us to explore the cosmos and the Wonder That Binds us to
each others and to the star like let us remember that in our quest to detect The
Mystery of the universe we are united by our s sense uh like and our unwavering
Bel in the power of Discovery like while going through the themes I just remember
the like something I written a year ago like about uh the how I begin my journey
and uh like the dream or like while I see when
I sleept okay so like I prepare poem from that
story uh so like uh U I wrote a small stories and I converted it into a poem
uh in the quiet of the night beneath the star Sky I stand in the O of the
universe with dream that fly as an astrophile my heart beats forther on un known with each sinking star a story to
be S from the Tinder age of nine I gazed of high dreaming of Distant Worlds where
I could fly Jupiter Earth rockets and settlement of far ignited with me a
passion or guiding star then there was The Nightmare also scary on a rocket
with friend feelings quite worried we were heading to the space where things went wrong fuel ran out and we could not
stay strong Panic set in his in his our rocket spawn fast but even in fear dream
Hold Us Ste fast for from small spark of w success can bloom in the darkest of
night dreams break the Gloom so here to Dreaming no matter how small it's what
keep us strong Standing Tall in the Twist and turnone of Life winding stream
our Dream Li the way like a guiding beam thank you that's very
nice yeah I love that so wonderful um we um uh miss hearing your
uh your poetry um deept so yeah like when I the email I saw the poem and it
was like oh I should WR the bo yes that's right so how are things going
with the uh with the naso group group in Nepal okay nasu is currently like busy
in the like Nepal like National eser like astronomy olympi and like a
International Junior olympi is going to H in Nepal uh so the preparation is
going on uh to welcome all the like from all different country uh to the par of
participants from all the way different countries and like recently Nepal Astronomical Society in the occasion of
like women and girls in astronomy month like I uh like corely celebrate uh this
February 11 is the like girls and women esteem or science and like March 8 is
the women's day and so this month is celebrated as women and girls in astronomy uh so recently in March 2 the
Nepal Astronomical Society honor and like organiz a small party type of
programs uh where all the girls and women in astronomy were gathers from the
Nepal and like uh they were honored and they share their journey together we had
like really good time togethers and uh we are engaging in different kind of Out
programs and recently there is organized K2 uh students program in which uh we
organize like different kind of programs for the higher Secondary School levels students like observations and uh
recently there's a declaration of physics tournament like high school physics tournament which is going to
like organized by Nepal Astronomical Society wow okay it sounds very busy sounds very
busy that's great that's great and how many members now belong to
nasau uh so there's a formally um like uh total more than 40s member uh in the
like uh for the like associative and other members in core members and like a
junior and like uh undergraduate members and all other members are likely more
than 50 to 60 and there are more of like who are engaged as a student and are
participating different programs and helping in this uh like um in the Out
programs and this s the enthusias like enthusiastic enthusiasm in like
participating and like uh to be engaged in different kind of outst programs
which is going to held in near their locality
wonderful wonderful well that's great okay so um we are going to move on to um
um our next speaker which will be marchello um uh marchelo soua but before
we go there uh I wanted to talk about the April 8th Eclipse uh and where you
might be able to go um we've been hearing I've been uh seeing uh news
stories I've been hearing personal accounts of people that have made
reservations like at hotels campgrounds you know way in advance uh
where they thought that they were getting a good rate uh only to find that
this uh this reservation was cancelled and um uh due to some crazy um uh you
know maybe madeup excuse one of them that I heard about on the news was uh
the guy reporting that he had lost his reservation because uh they had to do
sprinkler upgrades in the hotel then they come back with uh and he had rented
the hotel for like about $100 a month something like that um and uh uh not a
month a day excuse me and um uh that the the new rate uh afterwards is like 500
and so uh unfortunately there's some of this these kinds of things happening but
let me show you um an
alternative if you're so inclined let's
see I almost never share my screen guys so bear with
me here here we
go
here we are now this page this is explore scientific um
uh.com Eclipse uh and you can see that uh we
have um uh an event here if you just drop down this is called Crossroads of
the eclipses Expeditions uh the cost on this particular event is
$600 but that's by car and you can have up to three people in the car so um uh
you can use this private Campground uh it's actually a private Ranch uh and
it's right on the center line uh in uh Hill Country of Texas so uh we had a
very success annular Eclipse there and um um you know
we expect to have another successful uh total eclipse but if you're up for
camping uh whether you got an RV or a tent uh you can um you can go to this
particular um uh place and let's see if if we have yeah you can see the map of
where it is this is the uh the highway going down to a little town called
Leakey uh which is down here so you can see uh the area um it's it if it was
zoomed in you would see that there's a small air strip there and um so we
expect to have uh Mickey's kitchen uh Mickey's kitchen is um the same uh food
truck vendor that would attend the winter star party and so um we're really
excited to have Mickey's show up for her last harra at the winter star party but
um yeah so that's that's something that uh uh you can check into um uh David
Levy will be speaking at the event uh uh Dena the former president of the Denver
Astronomical Society will be there speaking and then we have other speakers as well um uh that will be at at uh on
the site uh there to share the experience with you but also to be giving uh some uh uh incredible talk so
um I'm excited this will be my fourth total eclipse uh and uh really my first
one where I just get to go and enjoy it you know uh normally when I do an
eclipse I'm I'm working during the event I'll be working this one too but not not
not to the uh the level that I was for the other eclipses so I'm looking
forward to all of that but um uh let's uh let's go uh back to uh
Cesar Cesar are you uh do you have uh anything here to show us uh yes I think
that is is um going we can try we can try it okay
because the telescope is appointing let me show
[Music] you this part of the sky where
is oh I see now
this okay okay we' got
Stars we have trying if we are lucky to show something in Karina because the
telescope is over vaa but we are trying to go to the Karina but Karina is now
maybe maybe let me
check
no no it's the the idea that I'm trting now
it's but let me let me try another thing okay uh it's a little tricky yes of
course that Karina is not Karina is over this part of of the the
roof my God this is the the astronomy From A
Balcony do you have parts and you need to wait the part of the sky that you are
interested yes and you know that's but like U like
the guys used to do like with the uh Leviathan telescope with the under
Parsons you know they they have over the side side wiggle
room but not much you know so yes yes and very quickly to show something that
maybe you don't have the opportunity to to watch something but really I prer
this that lose the the sky um we can try something in the in the area of uh of
the crooks um now I'm going with okay
catalog we are trying with
acrs
[Music]
got Stars again yes is another it's more the acrs
area groups area sou
cross this is crazy because in for example in April I have this part in the
time of the of the global Sur very clear and very easy to to show you but now
it's a mess and tonight the problem was that I I couldn't go to the rooftop
because they are working R roving the deck you know and they say no no I go to
the balcony but the problem with the balcony is that I have some interesting
areas of course that this area is is full of stars but I need to show you
more than only Stars without the
name because it's a it's a full area of asterism yes you have open
clusters very interesting very full of of clusters and open cluster and
especially asterism like this like Signs like uh uh different names
because the the quantity of stars well we continue
traveling well if you have some pres another presentation I I can uh
uh I can uh find found something
in half hour more the area is full of stars waiting
for marelo Souza to finish logging in okay minutes here okay Marcel is is is a
is running now because I can just on yeah ah okay okay okay well we are
searching open clusters here in this
area you're
thing I I'm traveling with the application
yes now in a direct
Ascension I'm going to the
South this is something that I like to to to make
searching this kind I like uh many
many um asterism like this look that it's a perfect C like ciss it's my ciss
asterism the asterism of course that we we can tell to the audience that it's a
imaginary small form like a constellation but to The View at the
telescope is an normally or vacular with the same idea of
constellation and imaginary and
shape with a Stars the people call asterism to this kind of
shapes well Marcel is ready I I'm searching something for
to show to the audience I come back I come back after Marcelo no problem
sounds good okay hi Marcel
excellent okay so marello let's
um uh bring you on hi yeah hi I'm sorry
for the problem here with my computer no problem everything up here at the same
time and the Windows update and then I had to wait almost two
hours for everything to update yes then
I I almost read I need only two minutes it's okay to because I
need to open the presentation here to show and I but I can talk here uh the
moment that I'm I'm organizing everything here I will talk today first
thank you Scott for the invitation and again I apologize for my problems here
but no problem when the computer don't want to work I think that's you know I I
do sales too you know and so I've when I used to use um Windows computers um uh
they're great computers and maybe the best computers for business but uh um uh
I have had more than once the embarrassment of of uh getting ready to
give a presentation and then Windows decides to do an update you know it's
like okay you know of course everybody in the audience understands but um
um you know that's the reason why I broadcast us using Apple products right
now so yeah uh generally I don't know who I
even I asked to don't update but I don't know it still it will still up update I
don't know why yeah but sure I think that everything is right and I I I try
to share my screen if you work then I can show okay okay let me I'll try
on a moment I put in presentation mode and I share
now
okay okay I'm share my
screen I think that's what can you see yes I see it okay okay thank you for the
invitation Scott again thank you a great pleasure to be here I I talk with
something that I am studying now that I don't know
if someone already knows about this that we call Miaki
events it is a recent results from
2013 from a Japanese physicist College
makak her her name is makaki first I will show some quick information about
the the earth and the magnetic fields and these are major of our
planets everything begin to change with the contribution of
vagna the because when you have fossils from Africa and from
Brazil the coast of Brazil North Coast of Brazil Northeast North Coast of
Brazil and part the coast Atlantic coast of Africa some regions of Africa in the
Atlantic coast the fossils in uh far
past are almost are the same then they imagine that in one moment these
continents were together and then they begin to to move and they separated but
nobody believes in him and when we had here you can see that
continent H looks like they like a puzzle you can join
them the South America and the Africa then he now we accept this idea
after the satellites in the 50s 1950s
you have now the idea that the P out continent to together and then they
begin to separate but not the continents as you see the Earth they have this regions
that are tectonic plates and the movement of these tectonic plates that is associate with
what we have now but why I'm talking about this here
we can see the Maes with without the water this was possible with had from the The Satellites after the
50s 1950s then now you know that you have a m
Atlantic here border another separated plates
here in Brazil we are safe from H earthquakes because we are in the middle
of the Atlantic this Mees Atlantic plates and the you have here regions
where the plates tectonic plates meet meet then a part where they are
moving apart separate but why is I'm why I'm talking
about this I'm not talking about earthquake Quakes because this is something that's important to understand
the magnetic field of the Earth this is
our Earth the inner part of Earth we have inner core sorry it's is in
Portuguese another after the inner core you have another core that's fluid the
inner core is solid then have the mle and then the clust and then the
atmosphere H you have a hot in a cross crust and then the heart in in a crust
transfer energy to the other layers of the earth and as they are fluid and
layers they move have movements and then the layers interact
with the others you have a a friction between layers and these frictions you
have ions that is have charged particles and charged
particles in movement they produce a magnetic field then this is the origin
of the magnetic field of the earth here you can see the last part of the last
layers near the surface you have the crust the oan crust that is f the
continental crust and the I don't know how to say how they say I don't know if
it's leosphere and the astinos spere that are the two layers in the mtal near
the the crust this is the movement of the crust that can
separate they can meet then can uh make
a movement to separate but not in Portugese is I don't know the
correct word in English you see here in the bottom is what is will probably
happen in the future with California and here's the magma the
movement of magma the tectonic plates but uh I go fast enough and this is what
cause they transfer energy and have convection yeah the hot like here I
have a model here with water the hot water is less dense than the cold water
then the hot water goes up and the cold water goes down have a permanent
movement in the earth if you imag have this move you have a hot core that transfer energy
for the m and then the part that begins in contact with the hot car now is hot
they move is less dense than the others then go up and the the part that is up
is cold then go down this movement that produce the movement of tonic plates and
is responsible for the magnetic fi and here you have twoes if you have
the meeting of this placeat in the ocean this is one that happening in
Asia that's why is a strong one and causes some think like the
digital glob saw what happened this image from Sri Lanka
before the and this Waters
ER return 400 m almost 400 m 3 343 M imagine you are
near the the coast in the beach on the beach and then you see the water living
and moving almost 350 kilometers far from you and then begin to arrive
the H big wave and destroy everything and this was a
traged a lot of people died before the tsunami after
tsunami and then these movements of the tectonic plates caus these kinds of
earth cakes and tsunamis that destroy this why one the
strongest that I saw in but it's not about this that I would
like to talk today and then now you know the origin of the magnetic field that protect us here on Earth and you
have they protect from mainly from the activity of the sun you have particles
that come from the Sun and the magnetic field particles are charged the
particles interact with the magnetic fields and they entering in the osphere
from magnetic poles but some moments you have very
strong activities in the sun like it
happened few weeks ago and the one that was very strong the
strongest one that was recorded that was caring events in the 19th
century but this what protectors ination
belt that is we call also the fing belt
and the AL radiation belt protect us here on Earth from this parles that come from
the Sun and what is new there was discovered in
2013 H it was discovered by a Japanese physicist that already said M here we
can see the trees have rings these Rings each ring that you we
can see here represents one year and you can see that they have
different sizes the Rings and she was studying the rings of
the trees a Japanese tree and what we already
knew sorry is this H we find a ISO isotope of a carbon
that is a 14 carbon and this isotop is produced in the upper
atmosphere by the incidence of cosmic rays that they interact they produce
neutrons Neutron that interact with the
nitrogen and produce the carbon 14 then when you
have strong activities in the sun we have a bigger production of carbon 14 in
the upper osphere and this isotope of carbon we have register
of them in the trees when we have a big production we find find the radio
isotopes in the trees then she was analyzing a
tree here is the physicist makak a
Japanese here a me of the Tre that she analyzed and she
saw aist she find she found aist of a
strong activity because she found a more H
isotopes of carbon 14 then was predicted then this is is
associated with a strong solar activity it this that she found happen
is event that happened in 7
773 years from our time after chist yeah
here are the the the PS that was found
774 and she found another one that's 90
993 and the only exp one of the explanation
of this register that measure in the tree is probably a
strong solar explosion a strong solar FL that
send had happened a strong Corona Mass injection and this affected the earth
atmosphere but this is so strong and the duration is one of them they found other
events like this uh they register five events
of this that goes until before Christ 10,000 years more l a little more
than 10,000 year before Christ and one of the events is so strong that they
imagine that you are 10 times stronger than the caring
events then if event like this happen today we have many problems with commun
iation with the satellites then was a very strong
event and they don't know the source of these events because as the duration was
a long duration then they imagine they are trying to understand what can
cause probably something stronger than we imagine that can happen with this with
son they proposed that maybe it was uh there
was some information that about a super
NOA but they didn't find H registers of a super
periods then they are yet studing Jing
the source of this kind of events but they have very strong uh very strong
events with charged particles
radiation that interact with the earth
atmosphere and it was discovered in 2013 the first SC is very near we have
11 years only and then they are studying and they they are
find new events like this that we don't know what is then and
we also don't know when it will happen again then some thing that is we need to
more stud about this and maybe we we
will find new data about these events this is
something that i' would like to share today that is a curious event and I have
new results very new results about this something
unexpected nobody was very waiting that this could be
and we are preparing our international meeting in April at the end of ail 25 27
April everybody will be very welcome here I hope you can visit us to
participate in these event and again I show our disguise Up
Magazine the last Edition that is a fantastic Edition thank you very much Scot thank
you thank you for uh your patience and perseverance there Marcelo thank you I
did I did my best I I hope you did very good thank you very much for it's a
great pleasure to be here yeah thank you so much thank you okay all right so we
are going um back over to um Argentina
uh to see what's happening off of Caesar's balcony here yes yes um the
first thing that the first op object that is in a clear part of the sky going
from from uh to the
explaining yes expain there yes let
me something that no okay no was that something of
the zoom control that show me like a a
mo but I don't know well now this is why the things are
appear in this part going so the rotation of in this part is the South
the things are the rotation of the object in the sky are going in this
direction okay this part of the buing is the South the m right here here now here
approximately here is the the S
pole in the sky okay we are going first of all to stellarium to show where is
app point the telescope um Thea Karina nebula is still
behind the roof but we are uh I we can
show uh a CL cluster that is the hand cluster NGC
31 uh 14 and I'll show you where
is okay
now this part of the sky is
going to show to be show show it later because I I have the roof of
vony but now actually this is the direction
the direction is going from from the uh left to the right and here is
where the telescope now is is uh
pointing is this is the the cluster that we are going to to to see now in real
life not in a map many people many people asked me if when I show this this
is real no this is a map we are going to see the real image of of the
cluster it's an open cluster really big cluster the another cluster in the area
of pakarina
is a wishing well cluster Nico
Nico took a lot of beautiful beautiful pictures of clusters Anda Karina neula
and Austin is processing now uh to show the next week uh the pictures with my
equipment uh this equipment the typical Cesar brolo balcony equipment the Appo
the APO telescope apoc chromic telescope I show
you and the the exus 1002 M uh this is
the my and was a pleasure that Nico used
my equipment last Friday in in San Miguel Observatory and uh with his
system of many many pictures uh he took a beautiful
beautiful pictures of many many object of the sou Southern ere well I'll change
my screen to the l view
screen we are going to the to the same the same cluster that I show
you but now now the real cluster okay this is and we can we
can make let me
try you can Center a little
better you can watch my my screen of the class now okay I moving the
telescope look that huge huge cluster yes and we
[Music] can make
an we can make this trip that is a live
stacking because we we don't need now your name
okay the idea is see if we can okay we can
clear
and uh yeah let me change this position
to make a much better let me
make let's gain more Exposition uh we can see four seconds
per s okay what we can see with more
stars or colors beautiful the first thing that we
can see Scot is that we are having different colors in the Stars when I
Chang it yes to the to the more Exposition and less game we are having
more control over the Colors Over the sensitivity of the colors of of the
camera is something okay 4 seconds is okay and the
the game is going to be 200k around 200
right I was just having some memory of shooting uh uh astronomical objects on
film and uh yes every time I see I see just a few
seconds go by and a digital image popping up on the screen uh of um of
stars or nebulosity it's it's always amazing to me even more amazing is that
you're in Argentina okay and we're watching around the world live so this
is really cool yes yes we are making
this kind of experiment nice experiment this is a live stacking and
look of uh we can having uh the the the the cluster
increasing increasing the number of object and the difference color of the
Stars the more interesting here is that we are having we are having
a a different different uh color of the Stars if uh later if I make
a h how do you say a process uh I can get a very
interesting levels of colors and more stars is very interesting is an open
cluster try with a little
more yes yes the thing is here is three raising
more and more but of course that is ready to be
processed the the things are that um that this need to be processed to to to
make uh of
course a different level of bries you
know but it's very interesting
okay perfect we are going to change the
game it's a great a great cluster very
interesting um well this is now the best
that I can show you because the if we go to the itak Karina nebula of course that
is is is covered by the
roof here is exctly thear nebula is in this area and the cluster is here
they are going in this position we are falling no they yes they are no they are
falling they are they are um let
me um yes it's like a like a c CLE circle
circle like a circle circle MH they making this this uh this is the
like they going yes little falling but by the line of the roof and this is the
geometry of the of the sky when you are having the things show watching to the
to the North or South pole that are for example do you have stars that never
never are going to the to the Horizon H the C polar stars or for
example the the Southern Cross in in Buenos Ires you never
see you never watch the Southern Cross h under the
Horizon now it's really really high in in the sky it's crazy because maybe you
are in Florida United States and you have the the the southern CRS in the
best part of the Year cyly Over the Horizon and here
is over your your head it's very interesting the hry of the sky
is well I I think that maybe maybe I
don't know I don't know sure if uh let me let me let me
try
no impossible it's over over
the is is beside the the of the V
and sou cross let check maybe maybe alent
maybe RI we are
trying
Ken let's goope moving that is very
interesting for the audience now the telescope is pointing
to the South East to
the
well maybe I I'll need a few minutes more to to to have a part of the sky
that that is clear if not next week no problem every week yes every week every
week yeah I'll have more for example in
April the the same that that I trying to show you now that maybe in one hour in
one hour maybe maybe in one hour uh I have clear
this part ah okay and in April for example Le it's totally clear and it's
easy to have Aina nebula um something that I prepare for
for for next week too it's a part in the balcony more a
small how do you say pedestal in English uh oh I I forget the name for for the Do
Not dog tail the the thing that where you have in the observatory uh it's like a column like
um well I use a normal tripod and I prepare in the corner of the balcony I
preparing uh uh well it's I can't believe that I
forget the name in English totally it's a pedestal it's a it's a I
forget the names in English too no yes but in Spanish too but well I I prepare
a in a colum uh to to put the in the corner of
the balcony and in the in the corner of the balcony I gain a lot of space and I
don't have problem um of the roof for example this part of of the balcony here uh you have
a lot of positions where for example in this time of the year is going is
have this this part of the sky um if I have let me show you Corner
oh yeah I putting here A Part a pier
Pier Pierre is okay Pier yes a small Pierre in this part in the corner
with the with the ex 100 yes I gain in
this part lot of space to have more parts in the year uh and maybe near to
the not exactly the the the part of the sky the The Horizon The Horizon the
Senate but near to the Senate and more of the South more because when um
especially the the North West is something that I have more space
if I put the appear in in the corner of the Viper and this something that
preparing for for much better shows and more open Open Sky but this part of the
year is where I have the part of the Galaxy very high and I need that this
part is going to to make another position where I have the position where
for example in April May is excellent because I have a Tarina or a lot of
things that I needed today but at the same time I have more more option to
show but but sorry Scot that I don't have more no you us around theide two
hour more no no no I'm sorry it's impossible no it's all good it was all good okay this is astronomy and this is
something that this is astronomy hey you had clear skies we got to see stars okay
we saw thean nebula you know so um and we got to see your setup and everything
so it's always a treat and it's wonderful to always talk with you Cesar so that's great thank you very much
thank you okay thank you thank you to the A and thank you by invite me yes
thank you so much prise a more object next week and I prepare the pier for for the corner of the

that's right that's right okay good night all right good night
Cesar okay so um I just wanted to thank uh our
audience and I want to thank our presenters we had a great lineup today we started the program with David Levy
who over at Jean Mueller's uh home and Jean Mueller is an uh is an old friend
to many amateur astronomers including me and uh certainly David um uh Jean is one
of the greatest uh living discoverers of astronomical objects with over a hundred
uh astronomical discoveries under her belt um you know tons of supernova
asteroids and comets uh she worked on the Palomar Sky survey too on the uh
Schmid camera up at Palomar Observatory so you could hear her in the background she is a little bit shy to be on video
but she was right there um of course you know uh having poetry recited from
memory from David Levy which is always a treat John glass came on next uh from
the astronomical League to talk about Mercury and how to spot Mercury and stuff I you know myself I've only seen
mercury three times uh with telescopes uh but uh it is a
treat to see that little tiny Crescent phase of that first planet in our solar
system that was followed up with Dr Ariel Kowski um uh from the unistellar
citizen science program she was talking about comets and uh you know that's
David ley's favorite subject of course uh if you don't already uh participate
in a citizen science program uh there's plenty to choose from right now and U so
you might want to get involved um uh Robert Reeves came on with his postcards
from the Moon uh talking about uh uh lunar detections uh Adrien Bradley came
on for a short time uh you know pausing from Bowling strikes uh at his local
bowling alley so uh always perseveres and helps us out see AR brolo uh came on
a couple of times here um uh doing his Southern Sky balcony uh astronomy we
went over to Nepal and visited with deept gatam again who gave his uh poetry
an update on the Nepal Astronomical Society and uh her take on detections in
in the universe marchelo sua was on as well um and uh you know always uh very
interest interesting subject this time makaki events uh which I uh still need
to study up on but U uh very interesting to have her on and our audience uh from
around the world uh very happy to uh uh have you uh tuning in from the um um UAE
from London from Belgium from uh all over the world uh it's it's it's
wonderful and really makes Global Star Party um truly Global um and so that's that's
wonderful I'm going to finish this program with uh uh this week at Nasa I
am a NASA solar system Ambassador and have been for a long time uh this
program is part of my uh NASA solar system Ambassador uh project and uh
you've now watched uh if you've watched all the global star parties you've seen 144 four of them so uh really want to
thank you for uh tuning in and um um as
uh my friend Jack horkheimer always used to say keep looking up and hope you find
this uh this week at Nasa uh program
interesting and in Asteroid missions close pass of the Sun a few of the stories to tell you about this week at
Nasa for the first time in more than 50 years new NASA science instruments and
Technology demonstrations have been operated on the moon a suite of six science instruments and Tech demos was
delivered to the South Pole region of the moon on February 22nd by intuitive machines odys
Lander the mission known as im1 was the first successful delivery for the
agency's commercial lunar payload service or Clips initiative and emis
campaign the Gusto scientific balloon mission is the new record holder for longest flight of any NASA heavy lift
long duration scientific balloon Mission it recently surpassed the previous record of 55 Days 1 hour and 34 minutes
while flying high above Antarctica Gusto is an astrophysics mission that is
mapping a large part of the Milky Way galaxy including the galactic center and the nearby large melanic
Cloud preliminary Telemetry indicates that our Osiris Apex spacecraft formerly
known as Osiris Rex recently completed an operation that brought it 25 million
miles closer to the Sun than it was designed to function the close pass of the Sun or parhelion was the first of
seven the spacecraft will make on its journey to study asteroid apus which is expected to have a rare close encounter
with Earth in April 2029 the recent carpet determination in
entirety measurements or carpet DM tests were aimed at helping researchers
examine the quality and ruggedness of a new generation of ground recording systems the recording equipment is
needed for future flight tests of our experimental x59 aircraft to confirm that it can fly supersonic while
producing just a quiet Sonic thump the x59 is not yet flying so an F-15 and an
F18 aircraft were used to make supersonic passes for the recording
equipment that's what's up this week at Nasa for more about what else we're up to check out
