Latest / Made of Stars / Earth Will Likely Be Devoured by the Sun (Eventually)
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 expand the vocabulary to include terms like quasar,
- 0:12asterism and uranus. Listen, that's your own risk, Go ahead?
- 0:22Whom made of stars? Made of stars? Star? Who starts? You?
- 0:33Could be from Highllywood, New Mexico? Mars? Where are stars?
- 0:43When we are made of stars? Joined by my good friend doctor Sean Cruizen
- 0:56from Columbus State University's Coca Cola Space Science Enter. I'm Wes Carol. Hey,
- 1:00Sean les. Good to join you this morning, my friend. Lots
- 1:04of fun space news today. We start today with a story that will,
- 1:11in theory, it seems, put us one step closer to something that we
- 1:15first talked about. It's been a while now, but the story about Tom
- 1:19Cruise being launched into space. Now, there have been a number of celebrities
- 1:23we thought that it would be fun to launch them into space. There were
- 1:26the people like you know, William Shatner and Michael Strayhand. Those were for
- 1:30good reasons, like let's launch them to space. Let's let them have this
- 1:34amazing experience. Of course, we found out later from Shatner it wasn't as
- 1:38great for him as we thought it was going to be because he's, as
- 1:42he's put it, he's getting towards the end of life. It was just
- 1:45too much for him to take in, to see that blank, open nothingness
- 1:48as he got up in it. But Strayhand, I think had a good
- 1:51time, you know. And then there's been some celebrities that we thought,
- 1:53man, wouldn't it be great? I mean, they were gonna send Pete
- 1:57Davidson up there, and you know, maybe could he get in, you
- 2:00know, one of those like Tesla's that shoots way into deep space, because
- 2:05you know, why not. So there's been you know, both sides of
- 2:07that. There's been some hey wouldn't be great to hear their experience. There's
- 2:10been some where you just go, can we just shoot him into space and
- 2:13get it over with? And I can name several others. It's just fun
- 2:15to pick on Pete Davidson because he was supposed to go on the third Celebrity
- 2:21Mission, But now Tom Cruise is supposed to go to space, and it's
- 2:24part of making a movie and the folks at Axiom were the ones that we're
- 2:29going to make this happen. Well, now their second mission to take civilians
- 2:35to space, right, it's a it's a good commercial astronauts to space,
- 2:38getting ready to go up on Sunday. Yeah. So so before we jump
- 2:44into a X two, which is the mission that's gonna maybe launch on Sunday,
- 2:49I'd like to address both the Pete Davidson and Tom Cruise issues. I
- 2:53remember the first time I ever heard of Pete Davidson. It's when I read
- 2:55the announcement that he might go to space. Prior to that, see,
- 3:00I didn't even know who he was, but apparently he's on a comedic show
- 3:04on Saturday Nights or something. He used to he used to be. Let
- 3:07me ask just at what point, like who was who was kind of one
- 3:09of the last high profile SNL people that you remember like watching, like you
- 3:15would tune in and go, hey there, I mean, was it was
- 3:17it back to Dana Carvey or was it will I do like that? We
- 3:25just like had the like anniversary or birthday or whatever for Joe Piscopo, I
- 3:30mean for Frank Sinatra and Joe Piscopo was doing all the rounds, like they
- 3:34had him on TV singing Frank Sinatra songs and I thought, well, that's
- 3:38just great, that's wonderful. So all right, so Piscopo, you go
- 3:42back that far. I mean, you know Kristen Wigg, I mean,
- 3:45I don't know, you know, I know I know some contemporary people.
- 3:49I think she would have. I think Kristin Wigg would have overlapped Pete Davidson
- 3:53a little bit. So yeah, you may have had some exposure. He
- 3:55just didn't leap off the page at you. Yeah, it's I knew of
- 4:00Christen Wig, not because I was watching Saturday Night Live. See that's the
- 4:03problem, right, I heard she was a Saturday Night Live person that I
- 4:06liked in other things. There you go. So you know that's why I
- 4:11don't know, you know. But good for Pete. I mean, you
- 4:12know, he had a shot. He failed, it didn't go. But
- 4:14you know whatever, he was busy in the Kardashians, and I mean sometimes
- 4:17when that and I mean quite frankly, they could have gotten a lot of
- 4:20seats for the deep Space mission with the Kardashians. I don't want it seems
- 4:26like low hanging fruit to make those jokes. But I mean, we could
- 4:30have just made it one quick. You know, how big of a tesla
- 4:32could they One of the trucks, maybe one of Elon's trucks they could have
- 4:35sent into I don't know, one of the cyber trucks. That's we could
- 4:39do that. I'm sure the Falcon heavy could lift the cyber truck off the
- 4:42ground. I mean, I'm pretty sure. I thought you were gonna say,
- 4:46it doesn't have to be like a return trajectory. Just get them out
- 4:48there, just get them up and out. There's all that anyway, No,
- 4:53we we love those fine entertainers. They are awesome people, and we
- 4:56are happy for them that they're famous. Anyway. The other one is Tom
- 5:00Cruise, and let me just say that allegedly he was working with Axiom.
- 5:04Allegedly, so there had been reports of the possibility that he was working with
- 5:10Axiom, and you know, I mean, they were out there, they're
- 5:14out there in the media, and so we thought maybe even this flight.
- 5:18There was a time after the first Axiom totally commercial astronaut mission went up to
- 5:25the International Space Station that that would result in the next round being you know,
- 5:30Tom Cruise, who was going to take his director and videographer with him
- 5:36two Space to actually shoot footage for a motion picture in Hollywood that would eventually
- 5:42end up as a Hollywood motion picture. Maybe it's a better way to say
- 5:45it anyway. So so then so we were thinking, Wow, maybe they'll
- 5:47go. But then then the AX two crew was announced and Tom's name wasn't
- 5:53on there. So so now you and I are speculating, Wow, does
- 5:58that mean he's in AX three. I mean, it seems like it would
- 6:01be to the advantage of Axiom to take him to space because it's a lot
- 6:06of free publicity, and I'll bet he could pay the ticket price. So
- 6:10I don't know, we'll we'll see how, you know, how it goes
- 6:13with the next the next all commercial astronaut mission to the International Space Station hosted
- 6:17by Axiom, Space and SpaceX. All of that that you said, Plus
- 6:21he's just come off of all of the you know, fighter pilot training.
- 6:25You would think he's kind of ready for this, right, I mean,
- 6:28I know, he did the fighter pilot training for the first top gun,
- 6:30then he did the set and now he's jumping off cliffs, you know,
- 6:33I mean, he's doing all kinds of stuff. I think he's probably as
- 6:36ready as you can be to go. Just think that that would at least
- 6:41be able to get him to mission specialist status something. I mean more one
- 6:45of these commercial missions would think that's true. I think that that, you
- 6:47know, that may put him ahead of some of the folks that went up
- 6:51on a X one. You know, maybe I would think, right,
- 6:55yeah, you know, I don't know, and I don't know so anyway,
- 6:58but let's not speculate that. Let's just go ahead and talk about a
- 7:01X two because there's some cool people going up on a X two and two
- 7:05of those people happen to be from Saudi Arabia. One of them is named
- 7:11Ali al Karni and the other one's name is Rihanna Barnawi. And Rihanna Barnawi
- 7:19if the if the mission is successfully launched to the International Space Station, Barnawi
- 7:24will become the first ever Saudi woman to go to space, Saudi Arabian female
- 7:30to go to space, which is a big, big milestone. And you
- 7:33know, I'm not going to speculate on any cultural kinds of situations, but
- 7:39it's just a big milestone that is a female from from that part of the
- 7:43world engage in space flight is a really cool thing. That is really Yeah,
- 7:48that's a significant glass sea that's like bulletproof glass ceiling in a lot of
- 7:54ways. And to be able to to make that that's that's a pretty huge
- 7:59milestone. It is a very huge milestone. And she would be traveling to
- 8:01space with one of the most famous film female astronauts of all time, who
- 8:07is Peggy Whitson, former NASA astronaut, record setting astronaut leader of you know,
- 8:13the Astronaut Corps for a period of time. And then also John Schaffner,
- 8:18who's an American private astronaut, but he's a pilot, flies both military
- 8:24and stunt aircraft, and so he's gonna be the pilot of the AX two
- 8:28mission and serve in that capacity. Peggy Whitson would be the commander of that
- 8:31mission, and then mission specialists would be ali Alcarney and Rayanna Barnowie. So
- 8:37this is a crew that's waiting to go. As we record the podcast,
- 8:41it's just a few days away. They're planning to launch on Sunday, and
- 8:46Sunday is May twenty first, So as we're recording to this podcast, it's
- 8:50the next upcoming Sunday on the calendar. They're gonna be launching if it goes
- 8:54on time, They're gonna launching in about five thirty seven pm Eastern Time on
- 9:01Sunday evening and then arriving up to doc with the International Space Station on May
- 9:05twenty second, about nine thirty in the morning, again Eastern time, so
- 9:09referencing to the time zone that we're in those those two times right there.
- 9:13So so it's it's a really exciting thing. They have a very small launch
- 9:18window, however, and so if they don't make their launch window, they
- 9:22do have another opportunity to launch the next day. But if they can't make
- 9:28that launch window, then there's a lot of other missions that are in the
- 9:31way. This is a Joel Montalbano, from NASA's International Space Station Program Manager,
- 9:37a quote on a space space news dot com where he says this,
- 9:43if we don't get off by the twenty second, and that's May twenty second,
- 9:46If we don't get off by the twenty second, we'll stand down with
- 9:50the a X two mission and turn our focus to SpaceX's twenty eight mission,
- 9:54the SpaceX twenty eight mission. So this is according to to Joel malt a
- 10:00month and apparently they'll have to reschedule the launch sometime after June third. It
- 10:03says Axium, NASA and SpaceX will get together and look for the next best
- 10:09opportunity. You see. What's happening is there are a variety of launches coming
- 10:13up. It's kind of a crowded schedule on the launch schedule. So there's
- 10:16a June third mission for a cargo mission up to the International Space Station.
- 10:22There's also the Boeing Starliner that's going to be launching on July twenty first,
- 10:28and they're making preparations for that mission. And there's also the regular NASA crew
- 10:33Rotation Crew seven going up sometime in July. So all of these upcoming missions
- 10:39they have to prepare for them on the ground before they can launch them.
- 10:41So it's it's gonna just be a little bit of a crowded launch schedule.
- 10:45And so Axium to the AX two mission. If it gets off the ground
- 10:50on the twenty first or twenty second, we'll see this mission carry out.
- 10:54But if not, they may have to wait a few months actually to get
- 10:56those astronauts up to the International Station aboard the axiom Ax two mission. Okay,
- 11:03so um, there's a study that says and this is one of those
- 11:07like you read the headline and you say, oh my gosh, this study
- 11:11says that maybe Saturn's rings are a relatively new phenomenon. But you have to
- 11:16remember that when we're talking about new or time or anything to do with space,
- 11:22that you know, new is a very relative term. So but according
- 11:28to this they're not as old as maybe we once thought that they were.
- 11:31But you know, I'm I'm seeing Okay, it's a newer phenomenon, but
- 11:33it's it's still pretty old. I mean, if i'm if I'm adding you
- 11:37know, the millions of years up correctly, they've still been around for a
- 11:43while, just maybe not as long as we thought before. That's exactly right.
- 11:48So, uh, you know, when you talk about things out in
- 11:52the universe, you know there are extremes, right, and so to say
- 11:56something is young means not young relative to your dog, you know, it's
- 12:01it's young relative to the rest of its surroundings. The Solar system itself is
- 12:07thought to have formed as the Sun formed, about four and a half billion
- 12:11years ago. So the rings of Saturn, we think, oh, well,
- 12:13Saturn just kind of formed and there was rings around it, and maybe
- 12:16it was a moon that didn't quite get to form as the rest of the
- 12:18planet was forming, and so those rocks have just been orbiting Saturn, the
- 12:22main body, four four and a half billion years. Well, no,
- 12:26as it turns out, that's not what recent studies are showing. And by
- 12:31the way, the study we're about to talk about today is not the only
- 12:33one that's kind of indicating that this is true. It's just the latest one.
- 12:37And so there's a study from University of Colorado at Boulder, And by
- 12:43the way, you can read about this on space dot com, or you
- 12:46can just go to the University of Colorado at Boulder's website, which is Colorado
- 12:48dot evu and you can check out their news release section there. So there's
- 12:54a scientist, a physicist by the name of Sasha Kemp, who is the
- 12:56lead on the new study. And this new study examined the dust that was
- 13:03in the in the Saturnian system. The data came from the Cosmic Dust Analyzer,
- 13:09which was aboard the Cassini spacecraft when Cassini went up there and flew around
- 13:13Saturn. Now that spacecraft is no longer, however, the data, the
- 13:18data archives are still there and scientists are still analyzing all that great work done
- 13:24by the Cassini spacecraft, and so this is a result of that. And
- 13:26so Kemp and his colleagues have examined the dust that accumulated on the particles that
- 13:35make up the rings of Saturn. So think about this like you could probably
- 13:39tell the last time you dusted the furniture in your house, right, you
- 13:46just kind of walked by and you do the finger swipe method. See,
- 13:50I have a different I have a different method for it. I've never dusted
- 13:52my house, so that's another way to do. So. Then if you
- 13:58compared your dust with Carol with the dust of somebody who was, shall we
- 14:03say, obsessive about dusting their house and maybe even compulsive, and maybe even
- 14:07they dust at their house two or three times a day, their their furniture
- 14:13on a finger swipe would have very little dust on it, whereas the same
- 14:18finger swipe at your house according to your reports, No, no, no,
- 14:20I'm dust I'm reporting my dusting frequency. My lovely bride takes care of
- 14:26the dusting. I make this joke on her birthday of all days. But
- 14:31yes, my lovely bride handles the dusting. I'm just pointing out when you
- 14:35say, when I dust my house, and it's it's it's very infrequent,
- 14:39is what I'm getting at. Well, And for the sake of my story
- 14:41here, let's just imagine the man cave from which you record this podcast.
- 14:45There you go that Jill is afraid to go into for you know, physical
- 14:48safety, you know, and there's that coarse shelf back there that we always
- 14:52see, you know, the Star Wars characters on. Imagine that shelf,
- 14:56like the amount of dust that may have built up there because it relied on
- 15:01you to dust it there. So there will be a lot of dust there
- 15:03because it's been a long time. And see time is the key aspect here,
- 15:09right, So there, dust builds up at a certain rate, and
- 15:11if a dusting process isn't undertaken for a period of time, a long period
- 15:18of time, you get more dust that builds up. Whereas out in the
- 15:20remainder of your house, where you're possibly or not OCD wife maybe is dusting
- 15:26more frequently, then there is less dust that builds up there because the time
- 15:33elapsed has not been long enough for sufficient dust build up. This is the
- 15:37comparison I'm trying to make with the rings of Saturn, because you see the
- 15:41cosmic dust analyzer was actually able to kind of measure how much dust was building
- 15:48up on the particles that make the rings of Saturn, and they only found
- 15:54one hundred and sixty three grains. Think about that. That's not very many,
- 16:00ladies and gentlemen. One hundred and sixty three. Now you'll have to
- 16:04go ahead and read the space dot Com story to figure out all of the
- 16:07research processes in all the ways that they look for these one hundred and sixty
- 16:11three grains. But just imagine with me that one hundred and sixty three grains
- 16:15of dust, if you can count them, it's not that many, right,
- 16:19And so that leads them to the conclusion that because dust sort of moves
- 16:26through the Solar system out from the Sun in a steady stream, that if
- 16:30they didn't find very much dust on these particles around the rings of Saturn,
- 16:36then those particles haven't been there long enough for the dust to build up.
- 16:41You see. It's back to that time argument. So if they had been
- 16:45building up dust for four point five billion years, kind of like Wes's shelf
- 16:51where the Star Wars characters are, then there would be a plentiful supply of
- 16:55dust. However, if they're you know, very few dust grains, very
- 17:00few dust greens on these particles around the rings of Saturn. They just haven't
- 17:04been there long enough for the dust to build up. That is the latest
- 17:10piece of evidence to suggest that we live in a very special time in the
- 17:15Solar system's history where Saturn has rings. Wow, that's weird, right,
- 17:22Yeah, So for most of the history of that very famous ringed planet,
- 17:30it has not had rings. It's only had rings for something like point oh
- 17:37one percent of its lifetime. But that just happens to be the same epoch
- 17:44in which we're living as human beings. So we've never known Saturn without rings.
- 17:48In fact, the rings of Saturn were one of the very first discoveries
- 17:53by Galileo that suggested that the Earth wasn't the center of the universe. And
- 18:02likewise, it also tells us that perhaps the rings of Saturn won't be around
- 18:07that much longer either. Now. I'm not worried about them going away in
- 18:11my lifetime or even in my children's or grandchildren's lifetime, but within say a
- 18:17few hundred thousand years, Saturn may not have the big bright ring system anymore.
- 18:23We are seeing a highly transient, short term phenomenon, that Saturn has
- 18:30rings. That's the interesting part of the story, right, And so again,
- 18:36this is one story from the University of Colorado, one piece of research,
- 18:40but it is contributing to a growing mounting collection of evidence that the rings
- 18:47of Saturn are a short term in the scale of the life of the Solar
- 18:51System phenomenon, and the rings of Saturn are probably going to be going away
- 18:55long before the Solar System goes extinct. It's a great story. We got
- 19:00another story from another planet, and it just seems like you're setting me up
- 19:03when you hand me a story that talks about the major moons of Uranus.
- 19:08Anytime all those words come together, you go from a Saturn story to the
- 19:15four major moons of Uranus. But possibility of liquid water on four of the
- 19:22major moons Urans that's pretty exciting. Yeah, that's a really cool story.
- 19:26And so there are computer models that are being carried out. So this is
- 19:30not direct observational evidence. And by the way, you can read about the
- 19:33story on Universe today dot com. So the new study is released by JPL,
- 19:41SETI and MIT scientists all working together. Project was led out of JPL,
- 19:45but it is a collection of computer simulations and models for the interior of
- 19:51some of the moons around the planet Uranus. And they include the moons named
- 19:56ariel, Umbrel, Titania, over Ron, and Miranda. And if you're
- 20:03if you're really hip, you might recognize those as Shakespearean characters. All those
- 20:07people, all those names came from works from Shakespeare. So those moons around
- 20:11Uranus are are modeled by these computer simulations. And they say, you know,
- 20:18given their density, given their proximity to both the Sun and the planet
- 20:22Uranus, the Sun providing certain amounts of heating, the planet Uranus through gravitational
- 20:26effects providing certain amounts of heating, it's really likely that four of the five
- 20:33of those have what we would call subterranean water or water below the surface of
- 20:38those moons Aerial, Umbreal, Titania, and Oberon. Only Miranda, which
- 20:45is substantially smaller than the other four, probably does not have interior oceans.
- 20:49So that would mean though, if that's true, that would mean that now
- 20:53we have four more places in our own solar system that are very interesting venues
- 21:00to go out and look for the possibilities of extraterrestrial life, in other words,
- 21:07life not living on the surface of the Earth, and so a really
- 21:11interesting study. The principal investigator on this project, her name is doctor Julia
- 21:15Castillo Rogues, and she has this quote. She says, when it comes
- 21:21to the small bodies dwarf planets and moons, planetary scientists previously have found evidence
- 21:26of oceans in several unlikely places, including the dwarf planets series and Pluto and
- 21:33Saturn's moon mimas. So there are mechanisms at play that we don't fully understand.
- 21:37This paper investigates what those could be and how they could be relevant to
- 21:44the many bodies in the Solar System that could be rich in water but have
- 21:48limited internal heating. So that was the quote from doctor Rogues. And so
- 21:52they're looking at other places that you know, they may not be They may
- 21:56not have a giant radioactive core like the Earth, but there are other mechanisms
- 22:00which can heat their interior. And if there's any frozen underground ice, it
- 22:06could thaw that ice into these liquid oceans and if there's liquid water. If
- 22:12there's liquid water, it's that becomes a very important place to look for signs
- 22:18of life in the Solar System. It's possible that someday the Earth will be
- 22:22eaten by our own son. We'll talk about that right after this. I
- 22:48feel like, with the amount of sunscreen that I have had on me just
- 22:55in my years of coaching soccer, I will be ready for whatever happens in
- 22:59the future if the Earth is swallowed up by the Sun one day. But
- 23:04this is a really cool story. It was actually shared by one of our
- 23:07regular listeners, Colin. He sent this to me a couple of weeks ago
- 23:11and he was like, Hey, this is kind of cool, isn't it.
- 23:12I was like, Yeah, the scientists that actually observed a star swallowing
- 23:21a Jupiter sized planet. That would be, you know, the big one
- 23:26for us, at least in this Solar system. I assume it would have
- 23:29been a large, one large planet in the Solar System where this took place.
- 23:33But this could be ultimately, what would happen to the now This isn't
- 23:38happening like next week or anything, right, I mean, if so,
- 23:41it's time to run up those credit card bills. Well, I mean this
- 23:45thing already happened to this other No, no, it happened to them.
- 23:48I'm talking about us. Yeah, Because if it's happening to us, like
- 23:51in a week or even a couple of months. It's time to you know,
- 23:53really enjoy those credit cards, is all I'm saying. Yeah, I
- 23:57know, I wouldn't run up the credit card bills yet, I would,
- 24:00you know, sell housing, buy coronas and watch the flame. No,
- 24:03it's that's we're not ready for that yet. We're not ready for that in
- 24:07our solar system, thank goodness. But you know, we did have just
- 24:10a minute ago, or in the first segment of the broadcast here, we
- 24:14had a story about the rings of Saturn being relatively young compared to the age
- 24:19of Saturn, And so when we talk about ages of planets, you know,
- 24:23stars can live a very long time, which means the planets around them
- 24:27can exist for a very long time. But there is an end point,
- 24:32and the endpoint happens when the star itself begins to burn out, which is
- 24:37what we're seeing in the story that we're talking about a different star with the
- 24:41planets around it, that the star reached the end of its lifetime. It
- 24:45used up all the hydrogen fuel in its core, and it began to expand
- 24:49out to a ridiculously large size. We call this phase the red giant phase,
- 24:56and it's a phase of that stars go through when they're reaching the end
- 25:00of their life cycles. Now, someday our own son is going to go
- 25:03through the red giant phase, and when it does, it will expand out
- 25:10beyond the orbits of both the Earth and Mars, let alone Mercury in Venus.
- 25:15And so all of those planets could suffer the same fate as this planet
- 25:22that we saw around this other star, which is that they are well,
- 25:26they succumb to the expanding envelope of atmosphere of their parents star. In other
- 25:32words, the star eats them, ladies and gentlemen. That's what happens,
- 25:36right, So that's that's your ultimate fate for planet Earth. We're gonna get
- 25:40eaten by our own son someday probably. And so that's what we saw.
- 25:45When I say we, I mean we as human beings. That's what MIT
- 25:48astronomers saw and reported in the May third issue of the journal Nature that they
- 25:53saw a star swallow a Jupiter sized planet that happened orbiting around it, because
- 26:02they saw the flash of energy that the star gave off as all of that
- 26:07material was converted from mass to energy and gave off a big bright burp of
- 26:12radiation as the star swallowed that planet. So in a statement from the authors,
- 26:18they say, if some other civilization was observing us from say, oh
- 26:22ten thousand light years away, while the Sun was engulfing the Earth, they
- 26:26would see the Sun suddenly brighten as it ejects some material then from the dust
- 26:32around it, before settling back to what it was. And so that's a
- 26:36similar kind of phenomenon that would take place. You know, if somebody was
- 26:40watching our solar system some period of time. The ten thousand by the way,
- 26:44the ten thousand light years away, that doesn't mean it's going to happen
- 26:45in ten thousand years. That just means that's roughly the distance we were from
- 26:52this other star that we observed. The swallowing of Earth won't happen for at
- 26:57least a few billion years, so you don't really have to worry about it
- 27:02too much unless you've got that extended life insurance plan. And so we're probably
- 27:07going to be okay in the short term anyway. So a very interesting study.
- 27:12There's a good article on Live science dot com. You can see it.
- 27:17But really this story, as you said, you know, your friends
- 27:18sent us in the reference and it made a lot of media out there,
- 27:22so it's all over the place out there, you know, all about a
- 27:26dying star swallowing up a planet. Something else pretty cool that was observed in
- 27:32the skies, specifically over Europe Aurora blobs. I had to look up the
- 27:37video of this and just see what these things were at almost it just just
- 27:44my perspective on it. Then you can explain exactly what we were looking at
- 27:47when I've watched I know you've seen it, but it almost looks like like
- 27:52a thunderstorm that's happening up in the sky, except it looks like, you
- 27:56know, northern lights versions of a thunderstorm happening in the sky. And they
- 28:00were just and I just kept thinking, Oh, what would someone have been
- 28:04thinking. You know, I don't know if hundreds of years ago, if
- 28:07they saw that in the sky, would they have wondered if maybe, I
- 28:10don't know, the Sun was about to eat our planet. It boggles the
- 28:15mind to wonder what they would wonder about. Yes, it could be that,
- 28:19or you know, is that the heavenly hosts come to Earth? Because
- 28:22this looks pretty darn scary, right, so probably would have thought that first.
- 28:26That probably would have come from it's the end of the world, as
- 28:30we know it one way or another. Anyway, ladies and gentlemen, do
- 28:33yourself a favor. Even if you're listening to this in the future, go
- 28:38back to today, which is May the eighteenth, May the eighteenth on space
- 28:44weather dot com. Pull it up from the archive if you're listening on a
- 28:48different day, and check out this series of photographs and the linked videos down
- 28:55below in their story. Because this is if you imagine seeing this in your
- 28:59own sky, it's truly frightening, right. Aurora phenomenon themselves are both beautiful
- 29:06and awe inspiring. So if you've ever seen the Northern lights or the Southern
- 29:10lights, they are incredible phenomenon. So imagine what you think of when you
- 29:17see northern lights. There's rays of color and splashes of light, and the
- 29:21skies glowing in reds and greens and oranges and pinks and a variety of colors.
- 29:26Then all of a sudden, there are bright concentrations of light that look
- 29:32like balls of fire in the sky, both white and green in color.
- 29:38That's what these aurora blobs are. And then the aurora blobs themselves begins snapping
- 29:48and crackling as if lightning was on the inside, and there's not a cloud
- 29:55in the sky you can see. And I'm talking about that heat lightning,
- 29:59which is really just thunderstorms over the horizon where the whole sky seems to flick
- 30:03her. No, no, no, you're seeing bright flashes coming from these
- 30:07circular blobs in the sky, as if Zeus himself had written down, you
- 30:14know, on a segue and is floating over the over your continent, throwing
- 30:18lightning bolts at you ladies and gentlemen. That's kind of what it looks like
- 30:19to me. I don't I don't know about the segue, but anyway,
- 30:22so it's kind of what it looks like to me. And so when these
- 30:25were photographed by the people all over Europe back in April, they made for
- 30:32quite an impressive set of photographs and videos that needed some well some splaining.
- 30:38We have to we have to have some splaining on these what is going on?
- 30:42So the April twenty third phenomenon has been explained by a variety of scientists,
- 30:48including space physicist Toshi Nisha Mura from Boston University. And what Toshi Nishimura
- 30:56said is these are not ordinary aurora. Yeah, no kidding, right,
- 31:00absolutely true. He said, they are called proton auroras, and they come
- 31:06from Earth's ring current system, so in other words, they're coming from something
- 31:11that's not exactly the same location where we normally see aurora phenomenon. Protons are
- 31:18dislodged from this, from this proton ring and come down and interact with the
- 31:23lower part of the atmosphere in a way that is highly unusual. So this
- 31:29doughnut shaped ring of current, it's basically an electricity ring around our planet,
- 31:34has millions of amps of current running through it. All of that is just
- 31:41loaded up with these protons, and these protons in certain storms, geomagnetic storms,
- 31:45which are the Earth interacting with a wave of material coming from the Sun.
- 31:49These geomagnetic storms can unleash these protons and they can, on rare occasions
- 31:56produce these crazy looking proton auroras which are just so otherworldly as to frighten people
- 32:04quite frankly. But then lots of skywatchers happen to get pictures of these.
- 32:08Again. One of our favorite websites here on this podcast is spaceweather dot com.
- 32:13Go check out the images on space weather, and they are absolutely beautiful.
- 32:17They're submitted from amateur astronomers and sky photographers all over Europe, including the
- 32:23countries of France, Poland, Germany, Denmark and more so as we start
- 32:29to really wind down the school year, we got a lot of schools in
- 32:34the Chattahoochee Valley area where we're based that are wrapping things up, finishing up
- 32:38their school years. Some I guess maybe you're already done by this point,
- 32:42but a few others will be wrapping up into next week. You guys kind
- 32:45of transition into a bit of a summer mode there at the Coca Cola Space
- 32:49Sign Center, and I just want to remind because there's always and I know
- 32:52you guys do summer camps. We've talked about summer camps. We've talked about
- 32:55some of the different things that you guys will be doing during the summer.
- 32:59But another thing that people can do. They're always looking for ways to keep
- 33:01their kids engaged, trying to come up with things that they can do so
- 33:05that kids don't completely shut down their brains for the entire summer. But something
- 33:10that they're able to do with you guys is to come in, like during
- 33:14the week, whenever you guys are open, come in, take a look
- 33:17around. There's so much to see and do while you're there and enjoy free
- 33:22air conditioning, because I know we've had an actual spring this year. We
- 33:24don't always get a normal spring. We've had spring. It's actually cooler right
- 33:30now than I could have ever imagined it would be on the eighteenth of May
- 33:32here in the Chattahoochee Valley area. But they heat is coming, my friends,
- 33:37It is coming in a big way. You know, winter is coming,
- 33:40Summer is coming, and free air conditioning is always a good thing.
- 33:45Yes, that's right West. You know, once people pay the door price
- 33:49for the tickets to the Atmosphere Theater planetarium and to see all of our artifacts,
- 33:52we do throw in the air conditioning for free. That's right on that.
- 33:55So that's sorry, there is no additional charge. So so yes,
- 34:00I would highly encourage people to come down the Star. That's exactly right.
- 34:06Well, you can see unlimited shows. So during the day you can see
- 34:08unlimited shows that our planetariums. So you can just hang out and just like,
- 34:12yeah, I'm not outside, I'm indoors where free air conditioning is being
- 34:15provided. Once I pay my ticket for admission, which is a very modest
- 34:20price, I might add of eight dollars for admission and what that's going to
- 34:22get you is unlimited shows in our Omnisphere Theater planetarium. Also, we do
- 34:27tours throughout the day of all of our NASA artifacts in our exhibit gallery.
- 34:30And we have an extensive collection of both Space Shuttle artifacts and artifacts from the
- 34:36Apollo program, provided primarily by David R. Scott, commander of Apollo fifteen,
- 34:43through his brother who is a donor and a benefactor of our facility here.
- 34:47So we have a David Scott collection of artifacts here at Space Science Center
- 34:51and they're really really cool. Come in and check all those out. We
- 34:53also have Mars rovers and fund other exhibits like green screens and flight simulators and
- 35:00all kinds of interactives in our gallery. And yes, if you're in the
- 35:02greater Chattoochie Valley area, or even if you're not, come on down and
- 35:06be in the greater Chattahoochie Valley area because we have a great museum here,
- 35:10and we also have great affiliated museums throughout the Chattoochie Valley, including the National
- 35:15Infantry Museum, which is just a few blocks away from us, just down
- 35:21the roadaways. And so come down to Columbus and enjoy our facility and all
- 35:24of the other great facilities, the National Civil War Naval Museums also in town,
- 35:31and a variety of others, the Columbus Museum, which is a fantastic
- 35:34art museum. Come enjoy all of their free air conditioning while you're here in
- 35:38the area. And when you're here at Space Science Center, you know,
- 35:43make sure you mention that you listen to this podcast, and you'd love a
- 35:45tour of the observatory. And if I'm in the building, I will be
- 35:49happy to walk you up and show you our telescope where we do our research
- 35:52here at Space Science Center and train the next generation of students for astrophysics careers
- 35:59at Columbus University and just in general space industry careers right here at the facility.
- 36:04So so come on down, come see us. We do have a
- 36:07lot of fun things going on all summer long. We also have our astronomy
- 36:10programs where we're collaborating with Calawie Gardens to be out at Calawe Gardens their park
- 36:16to do astronomy viewing sessions every Monday night all summer long. So, so
- 36:22all kinds of fun things going on. If you want to know more information
- 36:25about all of these things, check out our website www dot cc SSC dot
- 36:32org. That's a lot of season ss so I like to say it this
- 36:36way. Charlie, Charlie Sam Sam Charlie dot org, cc SSC dot org.
