Latest / Made of Stars / JWST Catches a Glimpse of Jar Jar Binks
Transcript
- 0:00Warning. The following podcast contains an entertaining look at astronomy, physics, and
- 0:04space news throughout the known universe. Listeners have been known to learn about astronomical
- 0:08phenomenon, the scientific method, and expanded vocabulary to include terms like quasar asterism
- 0:13and uranus. Listen, that's your own risk. Go ahead. When made
- 0:23of stars, made them stars, mad sizes. When made us stars,
- 0:33you could be from high they would New Mexicomus where all stars? When we
- 0:55are made of stars. I'm West Carol, joined by my good friend doctor
- 0:58Sean Cruisin from Lumba State Universities Coca Cola Space Science Center. Hey, Sean,
- 1:03Wes, it's an honor and privilege to be here with you again today,
- 1:07and I'm looking forward to a pretty fun discussion about some of the crazy
- 1:11things going on in space. Well we're at that part of May. Yesterday
- 1:15was I don't know if it's Timberlake Day whatever we call May first. Now
- 1:19I know it's May Day, it's got that, but you know, uh,
- 1:23May Day, and then there's Timberlake Day, and then we got this
- 1:26weekend. We get the because it's the weekend, it'll be Star Wars Day
- 1:30on Saturday, and then we've got Cinco de Mayo on Sunday. I know
- 1:38that today, the second of May is International Day of Prayer, what National
- 1:42Day of Prayer, whatever the but it doesn't have one of those sort of
- 1:47prayer day, like they don't call it that. It doesn't have that thing
- 1:49that just sort of rolls off the tongue. Although I guess with the state
- 1:53of things, we need to be praying today. But we have the sixth
- 1:59of May as as a significant day. Uh. And it's at this point
- 2:02still it's Starliner Day. That's what we're looking at. And we've been talking
- 2:07about this for a while, how we were leading into this, and as
- 2:09of now it is still a go for Monday. Yeah. And right along
- 2:15with that is my students know it's the final exam day for quantum mechanics class.
- 2:20So I don't think that probably made your docative days, but that's one
- 2:23that they're certainly looking forward to getting over with. I know that. But
- 2:28right after my final exam happens for quantum Mechanics, apparently NASA is going to
- 2:32be launching some astronauts to space with Boeing's help. So so that's that's a
- 2:38that's an important milestone right there, and we're you know, we were talking
- 2:43about this now for a little while about how they were looking at early May.
- 2:46We didn't know exactly when it was going to happen, and we've now
- 2:51known for a little while that they've been trying to get this done, and
- 2:53I guess this first week of May that would still be on course if they
- 2:58can make this happen on the sixth. So this is the Boeing CST one
- 3:02hundred. Its nickname is the star Liner. This will be the first flight
- 3:08of star Liner with astronauts on board, heading for the International Space Station.
- 3:15The launch time is set right now as of the recording of this show,
- 3:21for ten thirty four pm Eastern daylight time on Monday, May the sixth,
- 3:27So if it's a night launch, right that's that's kind of a cool thing.
- 3:31So you know, if you want to jump in the car and drive
- 3:34down to Florida, I'm not sure how, I'm not sure how in stone
- 3:38this launch time is. And as anybody knows, it's ever try to go
- 3:42to a launch, you know, there's often that they will drift off the
- 3:46original launch day for whether reasons or for technical reasons, or for other reasons.
- 3:51But right now, as we're recording the show, just a little less
- 3:53than a week ahead of this launch date ten thirty four pm Eastern daylight time
- 3:59Monday May, the same astronauts, Butch Wilmore and Sunny Williams, will be
- 4:03the first NASA crew to fly aboard a Boeing star Liner. Now we've documented
- 4:13on this show and formerly when Wes and I were on the radio, the
- 4:16long development of the Boeing star Liner developed alongside SpaceX Dragon, part of the
- 4:25commercial Crew program that NASA put into place. Hey, let's outsource our trips
- 4:29to lower Earth orbit to companies and let them build their own spaceships and figure
- 4:33out the launch vehicles and things like that. So that was that's what happened.
- 4:39So the contracts from NASA back in twenty fourteen for these commercial crew missions
- 4:45went to Boeing for their star Liner and they got about four point two billion
- 4:49dollars. Also went to SpaceX for the Dragon and the Falcon nine system two
- 4:55point six billion dollars. Two point six isn't quite it's a little bit more
- 5:01than half, but it's not a ton more than half. So in some
- 5:05rough manner of speaking, Boeing got almost twice as much money as SpaceX,
- 5:11and they have yet to fly an astronaut to space, whereas rides to space
- 5:15on SpaceX Dragon are almost commonplace. So that's that's really the setup. And
- 5:23here comes the pitch Monday, May sixth, ten thirty four pm. So
- 5:29we're kind of waiting, you know, it's an anticipatory thing. I was
- 5:32having some conversations with my friends here at Space Science Center. They were asking
- 5:36me if I was actually nervous about this launch. I like to think that
- 5:40NASA has really gone through everything, because they are definitely not taking this launch
- 5:46lightly. So I am sure that with their partners at Boeing, they have
- 5:50gone through the details of this mechanical operation with the fine tooth comb. So
- 5:57I won't say that I'm nervous. I will say I would have preferred to
- 6:00have seen a completely technically perfect, unpiloted launch of Starliner before we put people
- 6:08on Influentida space. That never really happened. However, you know, Boeing
- 6:13has said now that they have all of the technical problems resolved with this vehicle
- 6:17and it should be ready to go. So gonna just take them at their
- 6:19word and probably whisper a little prayer before lunchtime for Butch and Sonni and today's
- 6:26the day for it. Apparently, now that does exude a lot of confidence.
- 6:30I mean, we're not looking at a situation where they're saying, we
- 6:32feel okay about this. I mean they're they're putting a lot out there by
- 6:39putting astronauts on board. Yeah, that that speaks to their level of confidence,
- 6:45right, And so since they're the ones with the actual technical knowledge,
- 6:48I'm gonna go ahead and defer to them. And and I like to think
- 6:54that it's going to be a good mission. So it will be exciting to
- 6:57have two different launch systems going to space taking American astronauts making trips to the
- 7:01International Space Station. If something happened to one of those systems with a technical
- 7:06issue, or you know, if they saw some kind of faulting going on
- 7:10that they had to ground that vehicle for a certain period of time to figure
- 7:14that out from an engineering standpoint, the other vehicle could continue to go to
- 7:17space. So that's that's the really good thing about having a redundant secondary separate
- 7:24system during the Space Shuttle era, if you know, if they found out
- 7:27that tiles were being two cracked or you know, something else, some other
- 7:30kind of technical problem. It basically grounded the whole fleet until they could resolve
- 7:36that problem because there wasn't another way to get to space. Right. So
- 7:41so now we have these these two systems that should be coming into place by
- 7:45next week. And actually that's a good thing in the long run. I
- 7:48know this is not something new obviously, because we've got multiple different images of
- 7:57the horsehead nebula. But now that James Webb again another example of what James
- 8:05Webb is capable of. We've got a new and it's almost too detailed.
- 8:09It's almost too detailed because it's zoomed in so much of the horse head nebulae.
- 8:16I would just like to say this, and I know that this is
- 8:18not obviously brand new. I can stick with the horse head. That's fine.
- 8:24We're two days away from May to fourth. And this thing to me
- 8:28looks like jar Jar binks coming out of a cloud. That's all I just
- 8:31want to say. And that sort of terrifies me a little bit. Oh
- 8:35jar jar, That's all I have to say about that. Anyway. Yeah,
- 8:39me so want a picture taken by James Webb. I think is probably
- 8:43what he would say so well, let's talk about this. So first of
- 8:48all, James Webb Space Telescope definitely has the lead in terms of capabilities of
- 8:56any telescope that's producing really nice visual images. And we will remind all of
- 9:03the audience right now that these are infrared images. They're not visible light images.
- 9:07In other words, you couldn't see the same view with your eye that
- 9:11James Webb is getting with these pictures because it's coming in the infrared portion of
- 9:16the spectrum. However, other infrared telescopes have also taken extremely detailed and beautiful
- 9:20images of this iconic object called the horse head and nebula. And most people
- 9:26probably when they think of if you're savvy enough in the astronomy or amateur astronomy
- 9:33area, you know what the horse head nebula is. It looks like a
- 9:39little seahorse. It's a plume of a star forming region, and it looks
- 9:45quite beautiful, right. It looks beautiful and optical. It looks beautiful in
- 9:48the infrared. If you know of any picture of it in the infrared,
- 9:52the thing you probably have ingrained in your mind is the Hubble Space telescope image
- 9:58because it is absolutely gorge just filled with detail, interesting colors. Now the
- 10:03colors are false colors, but okay, they're there. It's a beautiful shot.
- 10:09Well, James Webb Space Telescope definitely has the highest resolution, and so
- 10:13recently the science team at James Webb released their own shot of the horse.
- 10:16Said Nebula and this close up, I mean, I think off air.
- 10:24I compared it with Wes. We were chatting. I said, it's like
- 10:26you were taking a picture of someone's face and all you could see was their
- 10:30cheekbone. And man, could you see the details of their cheekbone. Wow,
- 10:35you could see those you know, clogged poors in their skin on their
- 10:37cheek. You just can't tell who it is you're looking at. Yeah,
- 10:43I mean I guess to also nerd out a little bit. I mean it's
- 10:46if you've seen the Deadpool and Wolverine trailer. You might have noticed Deadpool and
- 10:50Wolverine jumping into a portal. You might not have noticed that it appears to
- 10:56be the eye socket of ant man his skull. So you know, it's
- 11:00kind of one of those details that you get. Yes, I was thinking
- 11:07of that exact example. So one of the things though that this image does
- 11:13show, it's let me just say I'm gonna go ahead and just go out
- 11:18on a limb, and I hope I don't offend any of the JWST people.
- 11:22It is not a cool picture of the horse head nebula. It's a
- 11:26cool picture that happens to have a piece of the horse head nebula in it.
- 11:31There you go, that's well, put the piece of the horse head
- 11:33nebula that you can see, which by no means can you tell it's the
- 11:37horse head nebula. But the piece that you can see, you can see
- 11:39a lot of detail in the cloud that is kind of like, you know,
- 11:43the back top mane of the horse itself if you zoom out and see
- 11:48the whole thing. But the one thing you can see in the image in
- 11:52addition to that, is you just see a field of galaxies. When you
- 11:56first look, you think, oh, look at all the stars in the
- 11:58back, But no, by far the majority of those are individual, very
- 12:05distant galaxies, and so yes, that does make this a very cool astronomical
- 12:13image. I won't call it a great picture of the horsehead nebula. I
- 12:16will call it a great astronomical image because of the detail you can see in
- 12:22part of the horsehead. But then this beautiful panorama of galaxies laying back behind
- 12:31the horsehead cloud in the distance is absolutely gorgeous and so so yeah, Okay,
- 12:37James Webb, they probably win the contest. It's like that old expression
- 12:41sometimes it's hard to see the nebula for the galaxies, you know, I
- 12:46mean, isn't it always true? It's true in this image at the very
- 12:50least. Yeah, I mean, you're right, it is. There's a
- 12:54lot going on obviously in the image. But yeah, I mean, you're
- 13:00basically getting the top of one of jar Jar's ears is all you're really getting
- 13:03for the horsehead nebulous So still, I mean, I don't know how you
- 13:07don't call it for the images in the background. Another win for James Webb.
- 13:11And it's always great when we get another update from James Webb. Let's
- 13:16talk about this, Cmeme. We've got a and this is one of those
- 13:22deals where I feel like it's almost like crying wolf, because we talk about
- 13:28it and we say, hey, this could be bad, and then it
- 13:31ends up kind of not being so bad at least that we're aware of.
- 13:35I don't know, we don't really know what's going on, right because they
- 13:39they happen, and I don't know if they're you know, throwing off some
- 13:41random satellite somewhere or maybe there's something that happened, but we feel it's important
- 13:48to alert you. I mean, it's just like, you know, people
- 13:50get upset and they say, why does the weather guy keep interrupting while I'm
- 13:54trying to watch TV, And he's like, I don't know, maybe because
- 13:56there might be a tornado. You might want to know about this. So
- 14:01I guess it's worth each time mentioning these CMEs, especially when they're potentially headed
- 14:07right for us, right right. So, And one of the things I
- 14:11like to do on our show, and I've got a little bit off kilter
- 14:15here, is I like to make sure people know the attributions. So let
- 14:18me go back and just say this quickly. The James Webspace telescope image.
- 14:22It's out there in lots of different places. In fact, people have been
- 14:24sending me links to that horsehead Nebula picture from a variety of different sources.
- 14:28We took our story today from Universe today dot com, so you can for
- 14:33sure go to Universe today dot com during the week of the recording of the
- 14:37show and you'll see that image on their blog about astronomy and astrophysics. The
- 14:43story about the coronal mass ejections coming from spaceweather dot com. That's a website.
- 14:48Both of them actually our websites we quote often on this show because they're
- 14:52great websites. You should try to follow these websites and maybe you'll know about
- 14:56some of these stories yourself as they come along. But there was another big
- 14:58storm on the that launched a bunch of material in the general direction of the
- 15:03Earth. It's coming from a sunspot group called Active Region thirty six fifty four.
- 15:09Maybe you don't have a T shirt with that on it already, probably
- 15:11don't, but anyway, so it's good to know that the sunspot groups are
- 15:16called active regions and they catalog them with numbers. So it launched into space
- 15:20what we call a C class solar flare that is based on the X ray
- 15:24intensity produced by the solar flare event. And that C class event triggered what's
- 15:31called a chronal mass ejection, where stuff is actually escaping from the Sun's surface
- 15:37and launching out through the Solar system. That cme that chronal mass ejection is
- 15:41going to pass by the Earth on star Wars Day. It turns out on
- 15:46May the fourth, and we tell you in part because of a caution.
- 15:48As Wes said, but this is not likely to produce any kind of serious
- 15:54geomagnetic effects on the Earth, but it can trigger northern lights. And friends,
- 16:00let me just tell you that if you haven't gotten a chance to see
- 16:03a fantastic northern light display occurring in the nighttime sky, you're missing out on
- 16:08one of life's great visions or great pieces of scenery natural occurrence. And you
- 16:15might say, well, I live where you guys live, I live in
- 16:18the South. I'm never going to see the northern lights. I have seen
- 16:21the northern lights on three different occasions just in and around the area of Columbus,
- 16:25Georgia where we record the show, So you can, in fact,
- 16:29and so one of the things I would suggest doing is following along with spaceweather
- 16:33dot com. You can even sign up for a service well where they will
- 16:37text you when there's a giant geomagnetic storm that's about to occur and they'll tell
- 16:44you, hey, might be a good opportunity to go look for northern lights
- 16:47in your area. So one of the things we like to do is we
- 16:51like to keep you informed of potential dangers, but we also just like to
- 16:53keep you informed of fun and interesting things that are taking place in the nighttime
- 16:57sky. So when we talk about chronal mass ejections and they're geomagnetic effects,
- 17:03it's partly so you might be able to see a northern lights display at some
- 17:07point in your lifetime. Then if you get an opportunity to see northern lights
- 17:14and I'll also hear the cicadas at the same time, then you're really just
- 17:18you're doubling down on all the sensory you know, maybe also eat a nice
- 17:22I don't know, a piece of cake or something while you're doing it.
- 17:25Start trying to hit as many senses as possible, is what I'm saying.
- 17:29You know. See, what you can add to funny about that is the
- 17:33cicadas that have had their seventeen years, a seventeen year hatch and whatever.
- 17:37They don't come out very often anyway, So they come out in great magnitude
- 17:41where I live, which because I live a little bit outside of town in
- 17:45a forested kind of area, there's lots of the cicadas out there, and
- 17:48there's just this constant hum and it's well, it's not constant. It actually
- 17:53turns on in the morning, yeah, and turns off at night, which
- 17:56is kind of nice. Actually, thank you cicadas for not going all my
- 17:59life. You know, it's maybe a little crazy, hard to sleep,
- 18:02but I would say this, I'm finding the sound strangely calming. I don't
- 18:07why I'm with you. It doesn't seem annoying to me. I mean,
- 18:11I know it's a buzz, it's like an all day long, constant buzz,
- 18:15but it's in this tonal region where it almost sounds like the phasers on
- 18:19Star Trek to me for some reason. I don't know, it's kind of
- 18:22a it's not kind of a screechy, high pitch thing. It's kind of
- 18:25just a I don't know how to describe it, a mid range white noise.
- 18:29And it's calming to me. I kind of like it. Yeah,
- 18:33I'm completely on board with that. And I've also sort of made the observation
- 18:36though that it if you're on Instagram or TikTok or one of those apps,
- 18:42and then you inevitably end up with you know, the ads that pop in,
- 18:45and it's like and it's the other way sponsored content, and it's like
- 18:49a girl in a bikini, and she's just kind of dancing around to try
- 18:52to get you to click on something with their website. That's kind of what
- 18:56the cicadas are doing, except it's the males. Right. That noise that
- 19:02you're talking about is the insect equivalent of look at me, I'm in a
- 19:07bikini, except it's the males. I mean, that's basically what they're trying
- 19:11to do, you know, just from a science standpoint. I'm only saying
- 19:14this for science, and they only have a short time to do. It
- 19:18must be successful, they must, so they got to go on. They
- 19:22gotta get your attention because they got to get the eggs in the in the
- 19:26ground, because seventeen years ain't gonna start too soon from now. They got
- 19:30to get back in the ground. Coming up, after a quick break,
- 19:33we're gonna talk about the devil comet because it's now visible in Australia down under.
- 19:40We'll talk about that right after this. All right, the devil comet,
- 20:04if you will, is now it's it's visible now in the Southern hemisphere.
- 20:11We don't have a look at it anymore. We talked about that how
- 20:14it would become now out of our view. They can now see it,
- 20:18and let's talk about solar wind in this comet. Yeah, so the comet
- 20:23that Wes is referring to picked up that nickname because it had kind of a
- 20:27horn like structure as it was approaching the Sun. Doesn't even really look like
- 20:32that anymore. This is comet. What we know is Comet P twelve.
- 20:37I'm sorry, commet twelve pe Ponds Brooks. And so the twelve P is
- 20:41a catalog number. The Ponds Brooks are the names of the discoverers, and
- 20:45they're both very famous comet discoverers by the way. Anyway, So so Commet
- 20:49twelve p Ponds Brooks went around the Sun right at the solar eclipse. It
- 20:56is right right in the you know, in the the day's immediately surrounding that
- 21:00event, and as it reappeared coming out from behind the Sun, it reappeared
- 21:07in the southern hemisphere, which is why people are seeing it from places like
- 21:11Australia right now. Spaceweather dot com, another one of our websites we would
- 21:15like to give attributions to to has a beautiful image today. This is the
- 21:22second of May. As Wes said earlier, it's a gorgeous image of comment
- 21:27Ponds Brooks, taken by an amateur astronomer in Australia. His name is Michael
- 21:34Maziazo Matiaso, Michael Matiaso. He's from Swanhill, Victoria, Australia anyway,
- 21:41So there's a lovely picture that shows a lot of structure in the tail,
- 21:47and the story on space weather today is reminding us that that structure in the
- 21:52tail is caused by basically waves or buffeting from the solar wind itself, a
- 22:00constant stream of particles coming out from the Sun. And so it's an interesting
- 22:04thing to see the structure show up in the comet's tail that indicates that this
- 22:11underlying wave of particles that are invisible to our naked eye are actually there.
- 22:17Because it wasn't that long ago that we were trying to decide whether the solar
- 22:21wind was really a thing or not. So back in nineteen ten, a
- 22:26very famous strunomer by the name of Sir Arthur Eddington suggested that similar structures in
- 22:33the tail of a comet called Comet Moorhouse indicated the presence of a solar wind
- 22:37or a constant stream of particles coming out from the Sun. We were not
- 22:42able to confirm the existence of the solar wind until the space age. So
- 22:48it was Eugene Parker, who was an astrophysicist that termed the name of that
- 22:56stream called solar wind. He came up with that term in nineteen fifty seven,
- 23:00and then the existence of the solar wind stream was verified in nineteen fifty
- 23:03nine by a Soviet spacecraft called Luna one. So again, knowing that there
- 23:10even is a solar wind is something that's reasonably new about fifty years old,
- 23:14and the fact that we can see it so clearly now in this image of
- 23:18Commet Ponds Brooks is just kind of a really fun confirmation of this constant outflow
- 23:23of gaseous material coming from the nuclear radiator that engine down in the inside of
- 23:30the Sun, the solar core. I want to talk about Martian spiders,
- 23:37and I know we've got the cicadas here. Mars has the spiders. They're
- 23:42everywhere, They're all over the place. They're just crawling around up there,
- 23:47and it's the first thing that we've really noticed on Mars since we sent monkeys
- 23:52up there. That goes that's a throwback to the radio show, by the
- 23:56way, when we talked about we know someone who thinks there's monkeys living on
- 24:02Mars. But anyway, Uh, but there's also not spiders there. What
- 24:06are the spiders? What can we get to the bottom of the spiders.
- 24:08Well, I mean, first of all, let me address the monkeys.
- 24:11Want to send a monkey to Mars? You have an infestation problem, clearly,
- 24:17you have, you know, cause an invasive species to take over a
- 24:19habitat. Yep, And so you know all of those NASA experiments where we
- 24:25send all those monkeys to Mars clearly was a bad idea. Yeah, I
- 24:27mean, it's it's uh, it's it's just asking for trouble. Really,
- 24:32I don't know how they would function in the space suits. I don't I
- 24:36doed they keep the bananas in the suit? I don't know what you do.
- 24:37I don't know how they're eating. But uh, they're they're thriving.
- 24:41And I've seen all those movies, those Disney movies on Sunday Nights where the
- 24:45monkeys get out of hand, and it's it's just a problem. So why
- 24:49would you ever send them to Mars. They're going to make a mess of
- 24:52the place. I don't know. But I mean, now you've got do
- 24:56they send the spiders to deal with the monkeys. What what's going on with
- 24:59the spider? I mean, fortunately, the spiders seem to be a native
- 25:03species, and I would say that those spiders would cause a serious problem for
- 25:07any monkey infestation coming from some kind of invasive species from Earth. So so
- 25:14beware Earth monkeys on Mars. Maybe you know, maybe we sent the monkeys
- 25:19to Mars to deal with the spiders and it's turned into a whole cane toad
- 25:22deal like in Australia. You know, the cane toads are now the problem.
- 25:26So maybe that's it. But no, we're starting to see these images
- 25:32popping up and it's got people talking about it, and obviously people go,
- 25:34hey, what's going on with this? We're just full up with clickbait stories.
- 25:41It really is a great clickbait story and it's but as we like to
- 25:45do on this show, we like to dispel all the clickbait. Although the
- 25:52title of the episode might be clickbait, I haven't decided yet. Yeah,
- 25:55I mean, it's it's a good one because you know, first of all,
- 25:57the horsehead Nebula was certainly a clickbait story. Yeah, uh, you
- 26:02know, the the comment the devil Commet has certainly been fair fair amounts of
- 26:07clickbait going on with that. Uh you know, there's there's always the clickbait
- 26:11in associated with astronauts going up on a vehicle for the first time, and
- 26:15you know, will they survive or whatever that's all about anyway, So so
- 26:18yes, clickbait insanity today on Made of Stars podcast, let me tell you
- 26:22this, friends I have received so people know, Hey, Shawn's into astronomy.
- 26:29Let's I see this fun astronomy link. Let me let me send this
- 26:32to him, see what he has to say. They don't ever read the
- 26:33story. They just they say, they just send me texts and it says
- 26:37things like, hey, what do you think about these spiders on Mars?
- 26:41So I get the text and I say, okay, that's cute, let
- 26:45me answer this. And then the next thing I know, I've got four
- 26:48more texts, Hey what do you think about these spiders on Mars? What
- 26:51are those things? It's like, okay, it probably said in the story
- 26:55that you clickbaited me, but okay, let me try to see if I
- 26:56can explain. And then I'm suddenly being over with clickbait stories. What is
- 27:02an Inca city? Did the Incas have a city on Mars. Come on,
- 27:04let's think for a minute, people, Let's just think apply the h
- 27:08the problem solving skills that we taught you in higher education when he came through
- 27:12the system. All right, so there's where we are. Now, let's
- 27:17address it. You've heard of it. You've probably seen it. It's probably
- 27:19shown up on your phone. Spighters on Mars. It has nothing to do
- 27:23with David Bowie or Ziggy Stardust. By the way, these are actual spider
- 27:29shaped objects on the planet Mars. And if they were real spiders, they'd
- 27:33be very large, like anywhere from three to eighteen meters across, so you
- 27:40know, three to eighteen yards across. These be large, so like a
- 27:44small spider in Australia. Yeah, like like it would be one of the
- 27:47smaller spiders in Australia. But that's another planet. So anyways, these structures
- 27:55on Mars that have been photographed by the European Space Agency's XO Trace Gas Orbiter
- 28:00or the TGO, are actually plumes of gaseous material that are building up underneath
- 28:08a sheet of ice near the south polar region of Mars. And what happens
- 28:14is as the seasons change and as the sun begins to finally shine on this
- 28:18area on Mars that's been dark for several months. The ice begins to melt
- 28:23from the bottom upward, and so then what happens is these fractures that occur
- 28:30in that ice icy layer invoke geysers, and usually that geyser material just shoots
- 28:37right out of the top of the ice layer lands on the outside of the
- 28:40ice, and it doesn't really make spiders. But what happens sometimes is certain
- 28:45regions can be melting from the top I'm sorry, from the bottom up,
- 28:48and the top layer is still so solid that these geysers can't escape. And
- 28:53so you basically have a geyser from melting CO two from a lower level of
- 29:00that CO two ice shield, and it's just splattering into a top yet unmelted
- 29:06layer, and it makes a piece of art that we have now identified as
- 29:11Mars spiders. They are, you know, multi legged structures that look a
- 29:15bit like an ink blot. Some people thought they looked like spiders. There
- 29:19we go, So that's what this that's what these objects are now. The
- 29:23fact that they're found near some structure on Mars called the Inca City, and
- 29:29by the way, it was nicknamed the Inca city back in the nineteen seventies
- 29:32when it was first discovered by one of the Viking missions. So this was
- 29:36an interesting thing. It is a geological feature that we really don't completely understand,
- 29:42although we do think as a group of scientists it is highly unlikely that
- 29:45the Incas themselves colonize the planet Mars. So it's really unlikely that it's actually
- 29:52an Inca city. It just looks like an aerial shot of Machu Pichu.
- 29:57So the structures are likely some kind of geometric fractures in the surface of Mars
- 30:04caused by volcanic pressure from beneath that pushed up through those fractures in a certain
- 30:11pattern and form these line, these long lines of dune like structures or cliff
- 30:18like structures that look somewhat square. And let's remember that that square appearance,
- 30:23or the appearance of right angles or something near right angles, is due to
- 30:27the underlying geometry of the geological structures in that area. So that's the way
- 30:33they fracture, because that's the way they're shaped. And so if that happens
- 30:37on smaller scales, it's compounded to bigger scales, and then you get something
- 30:41that looks like an Inca City near the south pole of Mars. By the
- 30:45way, this feature is actually called the Augustus Labyrinthus, the Labyrinth of Augustus,
- 30:52like Caesar Augustus, right, So anyway, there you have it.
- 30:56Friends, that's the spiders living in the Incas city on Mars. We still
- 31:02haven't figured out where all the monkeys are. We're into May. That means
- 31:07the school year is winding down, and that'll be a little bit of a
- 31:11transition for what you guys are doing at the Cocola Space Science Center. I
- 31:15know you'll have some school groups coming in as the school year winds down.
- 31:18That's just a very popular field trip obviously, And anybody listening, by the
- 31:22way, that's not in our immediate Chattahoochee Valley area that already has kids that
- 31:29come to the school. If you're listening somewhere beyond and a field trip is
- 31:34something that you know you would like to do with your kids at some point
- 31:40in the future, bring your kids in from elsewhere. I know I was
- 31:42there one day and there were kids from other school districts, other cities coming
- 31:45in. That's a pretty common thing for you guys. But you guys will
- 31:49be also transitioning into this summer mode where I know you're going to have camps
- 31:55and things going on there. But again, people are always looking for ways
- 31:59over the summer to keep their kids engaged and not just staring at a screen
- 32:04in front of them their phone or tablet or computer or video game, whatever
- 32:07it is. There's some things that are similar to that there that they can
- 32:12do while also learning over the summer. Yeah, let's let's remind everybody that
- 32:19first of all, no one knows where the Mars monkeys go when the spiders
- 32:22come from below. So that's that's an important scientific thing we have to get
- 32:25out. Yeah, that's true. The other thing is we have we have
- 32:30a brand new exhibit at the Coca Cola Space Science that are It's good for
- 32:34the youngest visitors. We're talking pre K up through about third grade, but
- 32:37I will tell you even the middle school students and of the high school students
- 32:40like to play with it as well. It's called the guzzle Vortex, so
- 32:44it sounds a bit like Augustus labyrinthus, but it's called the guzzle Vortex and
- 32:49it's a it's an exhibit in our exhibit gallery where you can feed aliens of
- 32:53an exol planet type nature. You feed them a special food, and then
- 32:58their food goes through an air maze and flies out through the air and comes
- 33:01back down to the ground, and you can feed the aliens again. And
- 33:05you can sit there and feed aliens for just as long as you want and
- 33:07watch all these pieces of alien food fly out from the air maized tubes from
- 33:13high up above in the top part of the exhibit gallery here at Space Science
- 33:15Center. It's a good way to just have fun. First of all,
- 33:20not everything has to be about education. Sometimes you just want to have a
- 33:22good time, so it's good for that, but you can teach your kids
- 33:27also. You can begin to introduce ideas about could there be alien life in
- 33:31the galaxy? What are planets called that don't orbit the Sun? They're called
- 33:35exoplanets. By the way, how do airplanes fly? And how does air
- 33:39move masses through the air, kind of like in the air maze itself.
- 33:45So there's lots of fun topics that can be addressed with this one exhibit.
- 33:47It's a exhibit sponsored by our friends at Pratt and Whitney and it's a lot
- 33:52of fun and our stay time at this exhibit has been great, which means
- 33:55we just noticed that families and kids are staying there for a long time,
- 34:00having a good time at that one exhibit. But don't forget. We also
- 34:01have our flight simulators, We have our Mars rovers, we have our green
- 34:05screen, we have our infrared camera, we have dozens and dozens of NASA
- 34:09Space Shuttle and other artifacts on our exhibit gallery, and we have our newly
- 34:13upgraded Omnisphere Theater Planetarium, all for one low admission price. Friends, you
- 34:21pay once, see as many shows, fly, as many flight simulators,
- 34:24have a great time on our Space Shuttle Odyssey, play with a dozen Vortex
- 34:28drive cars on Mars. All of these things for one low admission price.
- 34:31So if you're looking for something fun to do as school is winding up,
- 34:36keep us in mind. Bring the kids over to Columbus, Georgia, hang
- 34:38out for a few hours with us here at Space Science Center, and you'll
- 34:42have an awesome time. If you want to know more information about visiting the
- 34:45Science Center or all of the programming that we have going on, well why
- 34:49don't you check out our website. I know it sounds a little old fashioned
