Latest / Made of Stars / What's that Big Jellyfish In the Sky?
Transcript
- 0:00Speaker 1: Warning, the following podcast contains an entertaining look at astronomy, physics,
- 0:04Speaker 1: and space news throughout the known universe. Listeners have been
- 0:07Speaker 1: known to learn about astronomical phenomenon, the scientific method, and
- 0:10Speaker 1: expand their vocabulary to include terms like quasar, asterism, and Uranus.
- 0:14Speaker 1: Listen at your own risk. Go ahead.
- 0:22Speaker 2: We're made of stars. Made of stars. Made of stars.
- 0:29Speaker 3: We're made of stars. We really are.
- 0:33Speaker 1: You could be.
- 0:34Speaker 2: From Hollywood, New Mexico, or Mars. We're all made of stars.
- 0:54Speaker 2: We are made of stars.
- 0:56Speaker 3: I'm Wes Carroll, joined by my good friend, Dr. Sean Cruz,
- 0:59Speaker 3: an executive director at Columbus State University's Coca-Cola Space Science Center.
- 1:04Speaker 2: Hey, Sean. Hey, Wes. Good to be here today.
- 1:07Speaker 3: So I'm really kicking myself because the other morning I
- 1:12Speaker 3: was sitting at my TV watching the Falcon 9 launch
- 1:19Speaker 3: as the SpaceX was sending up the cargo mission to
- 1:25Speaker 3: the International Space Station. I was watching the launch right
- 1:30Speaker 3: there on TV. Like, they're showing it. They break in
- 1:32Speaker 3: coverage on the news. I had been watching kind of
- 1:34Speaker 3: the countdown leading up for about an hour out. And
- 1:38Speaker 3: then they get closer to it, and they're really counting
- 1:40Speaker 3: it down. And I thought, huh, it's still dark out.
- 1:45Speaker 3: This thing is launching. I could probably go outside and
- 1:49Speaker 3: see it. And then for some reason, like an idiot,
- 1:53Speaker 3: I just didn't do it. And then within 10, 15 minutes,
- 1:57Speaker 3: I start seeing on social media, what is this in
- 2:01Speaker 3: the sky that looks like we're being invaded by aliens?
- 2:04Speaker 3: And I thought, oh, why didn't I just get up?
- 2:07Speaker 3: What am I doing here? But yes, we had this
- 2:11Speaker 3: really cool moment that sometimes here kind of, we don't
- 2:14Speaker 3: have to be right on the coasts. sometimes to see
- 2:18Speaker 3: a rocket go up. And this was one of those
- 2:20Speaker 3: cases and I blew it.
- 2:23Speaker 2: I will just tell you that whatever your story is,
- 2:26Speaker 2: which is a good one, by the way, mine's worse
- 2:31Speaker 2: because let me just say that. First of all, the
- 2:35Speaker 2: giant cloud in the sky that looked like we were
- 2:37Speaker 2: being invaded by aliens that Wes just described that happened
- 2:41Speaker 2: on Tuesday morning. I will tell you that no excuse,
- 2:45Speaker 2: but it, you know, it's just a reason. I had
- 2:47Speaker 2: a Monday of all Mondays. It was a Monday, Monday.
- 2:51Speaker 2: And so my head had gotten off space just a
- 2:53Speaker 2: little bit. And I will just admit right here on
- 2:56Speaker 2: this podcast that I had forgotten there was even going
- 2:58Speaker 2: to be a SpaceX launch. Now, this is sad for me, right?
- 3:02Speaker 2: This is literally my stock and trade. And I forgot.
- 3:06Speaker 2: I was just distracted. My wife and I were out walking.
- 3:10Speaker 2: We live on a beautiful country lane. It's tree-lined. It's gorgeous.
- 3:16Speaker 2: out in the rural community surrounding Columbus, Georgia. But those trees,
- 3:21Speaker 2: they tend to obscure things that are close to the
- 3:23Speaker 2: horizon for the most part. So while my wife and
- 3:27Speaker 2: I are walking at approximately 6.35 a.m. on Tuesday morning,
- 3:33Speaker 2: we noticed like the starry sky. In fact, we even said, oh,
- 3:37Speaker 2: you know what? The International Space Station is going over.
- 3:39Speaker 2: I got a little alert from my app on my
- 3:42Speaker 2: phone that said, oh, check out the ISS. And we
- 3:44Speaker 2: watched and there it was. The ISS went sailing over
- 3:48Speaker 2: our heads. And I said to my wife, I said, well,
- 3:51Speaker 2: it's a good thing that that part of the sky
- 3:53Speaker 2: was clear, unlike all that cloud I'm seeing down there
- 3:57Speaker 2: in the southeast. That cloud that is obviously being illuminated
- 4:01Speaker 2: by the moon, because wow, that looks really interesting this morning,
- 4:05Speaker 2: through the trees that almost entirely obscured it. Little hint
- 4:10Speaker 2: for everybody in the audience. The moon is a waxing crescent,
- 4:14Speaker 2: which means you don't see it in the morning. which
- 4:17Speaker 2: means if you're an astronomer, you should know this and
- 4:19Speaker 2: pay attention. Like myself, I was not paying attention either
- 4:23Speaker 2: to the launch nor to the phase of the moon,
- 4:26Speaker 2: and I assumed that that cloud was being lit up
- 4:29Speaker 2: by the moon. No, friends. That was a SpaceX jellyfish
- 4:36Speaker 2: just totally covering the southeastern horizon. And the part that
- 4:41Speaker 2: looked so bright that I thought was the moon illuminating
- 4:43Speaker 2: the background, was actually the main stage booster shoving its
- 4:48Speaker 2: way back to a landing at the Kennedy Space Center.
- 4:53Speaker 2: And in fairness to myself, which I don't really need
- 4:57Speaker 2: to be fair to myself, I should have said, you know, hey,
- 5:01Speaker 2: this is weird, but it was a really obscured view.
- 5:03Speaker 2: I only was catching glimpses between dense trees in the
- 5:08Speaker 2: Georgia forest. But yet, My brain didn't connect enough dots
- 5:14Speaker 2: to say, no, I don't think that's the moon. That
- 5:18Speaker 2: looks weird. And because I didn't cross that threshold, I
- 5:23Speaker 2: didn't ask any more questions of myself. And I just said, well, yeah,
- 5:26Speaker 2: it's weird that that cloud is just laying there in
- 5:28Speaker 2: the southeast and the rest of the sky is so
- 5:31Speaker 2: clear that we can see the International Space Station flying over.
- 5:35Speaker 2: And I missed the almost end times appearance.
- 5:41Speaker 1: Oh.
- 5:41Speaker 2: Of this unique SpaceX jellyfish cloud.
- 5:46Speaker 3: That International Space Station should watch out because that thing's
- 5:49Speaker 3: flying right at it.
- 5:50Speaker 2: It is. It's like ISS was flying over and the
- 5:55Speaker 2: Kennedy Space Center just took a pot shot at it.
- 6:00Speaker 2: It's almost like it's.
- 6:01Speaker 3: Headed right for it. Well, you saw more of all
- 6:06Speaker 3: of this than I did because all I saw was
- 6:08Speaker 3: the footage from my TV, which I could see anytime.
- 6:12Speaker 2: I mean, literally 15 minutes after I'm back from this walk,
- 6:17Speaker 2: I did the same thing you did, which is, I
- 6:19Speaker 2: saw social media and it was just exploding with people
- 6:23Speaker 2: right here in our own community. We're getting absolutely mind
- 6:27Speaker 2: bending images of this thing in the sky. I literally,
- 6:32Speaker 2: all I could do is shake my head in the
- 6:34Speaker 2: mirror at myself.
- 6:35Speaker 3: I literally saw a post from someone that said something about, uh, uh,
- 6:41Speaker 3: you know, what is this.
- 6:42Speaker 2: In the sky?
- 6:42Speaker 3: And it was someone I don't really talk to very much.
- 6:45Speaker 3: And I went, Oh, please be in Florida. Like, please, please.
- 6:49Speaker 3: Please be somewhere along the coast, at least Savannah maybe.
- 6:53Speaker 3: And I was like, no, they're here. And I think
- 6:56Speaker 3: they may even be more to the west of where
- 6:58Speaker 3: I am.
- 7:00Speaker 2: I'm going to tell you that our mutual friend, Tyler Allender,
- 7:03Speaker 2: who is a weatherman in this community, was posting, hey,
- 7:07Speaker 2: you could see this jellyfish just like I told you
- 7:09Speaker 2: you were going to be able to last night. Tyler. Tyler.
- 7:14Speaker 2: I wish I'd saw your post, but I wish I
- 7:17Speaker 2: would have paid attention. It's not your fault, Tyler. It's mine.
- 7:19Speaker 2: I'm going to own it.
- 7:21Speaker 3: Yeah.
- 7:21Speaker 2: Yeah. I missed it. I missed it. You know, we both,
- 7:24Speaker 2: I quasi missed it.
- 7:25Speaker 3: We both had other things going on. So there was
- 7:28Speaker 3: a reason we were both a little distracted. So it
- 7:31Speaker 3: happened though. And a lot of people saw it. So
- 7:33Speaker 3: if you never got the full story and you're listening
- 7:36Speaker 3: to this, I don't know how you haven't already gotten
- 7:38Speaker 3: the full story, but that's what it was.
- 7:40Speaker 2: Hey, maybe friends, maybe you've missed all of these social
- 7:43Speaker 2: media posts. And you want to just see it because
- 7:46Speaker 2: you're hearing the story. Spaceweather.com. If you're hearing this in
- 7:50Speaker 2: the future, past October 15th, just go back to the
- 7:54Speaker 2: October 15th using the Wayback Machine, the archive right there,
- 7:58Speaker 2: and check out October 15th post, spaceweather.com. They have an
- 8:02Speaker 2: absolutely amazing, not only image on their website, but a
- 8:06Speaker 2: video taken by somebody in Florida where the person taking
- 8:10Speaker 2: the video is actually describing all of the steps. And
- 8:12Speaker 2: you can see that the very... It's an extraordinary sight
- 8:16Speaker 2: anyway to see one of these clouds made from a
- 8:19Speaker 2: SpaceX rocket. But it's super, it's different. It's super extraordinary
- 8:23Speaker 2: when it's got the main stage booster that actually kicks
- 8:26Speaker 2: a secondary cloud into the flow of the jellyfish because
- 8:32Speaker 2: it's kicking its way back to the Kennedy Space Center
- 8:35Speaker 2: instead of landing out on a dock out in the
- 8:37Speaker 2: Atlantic Ocean. And so that's why this one looks so weird,
- 8:40Speaker 2: so unusual that even the Florida people were freaked out
- 8:43Speaker 2: by it. And it is an absolutely spectacular site. That
- 8:48Speaker 2: boost back burn really just punctuating the structure of that
- 8:54Speaker 2: secondary explosion of those engines as they're shoving their way
- 8:58Speaker 2: back to the original takeoff site, the Kennedy Space Center.
- 9:01Speaker 2: So check it out. In the meantime, by the way,
- 9:03Speaker 2: the rest of that payload, the actual Dragon capsule, has
- 9:07Speaker 2: docked with the space station and delivered 6,300 pounds of Twinkies.
- 9:14Speaker 2: And toilet paper and other supplies. Now, some of the
- 9:16Speaker 2: other things, of course, there's food, but there's also new
- 9:19Speaker 2: solar arrays. There's equipment to manufacture artificial retinas in microgravity.
- 9:27Speaker 2: Like you probably didn't know that experiment was going on
- 9:30Speaker 2: unless you're a super insider in the space program. Equipment
- 9:34Speaker 2: to manufacture an artificial retina. So if you're having some
- 9:39Speaker 2: kind of a retina degeneration problem, The space program is
- 9:43Speaker 2: trying to solve that medical issue for you by being
- 9:46Speaker 2: able to manufacture artificial retinas in the unique environment of microgravity. Also,
- 9:52Speaker 2: an experiment is something called organoids, which are part of
- 9:57Speaker 2: Alzheimer's research that, again, can only be conducted in microgravity.
- 10:02Speaker 2: And so the work on the brain's organoids might actually
- 10:08Speaker 2: help the insidious problem of Alzheimer's that affects so many families,
- 10:13Speaker 2: so many loved ones. And this research is taking place
- 10:16Speaker 2: as of today in very soon aboard the International Space
- 10:19Speaker 2: Station because that giant jellyfish appeared in the sky above Florida, Georgia,
- 10:24Speaker 2: and other places. Actually, the jellyfish cloud was seen all
- 10:27Speaker 2: the way up the eastern seaboard and as far west
- 10:30Speaker 2: as Ohio and Tennessee. And I still missed it. How
- 10:35Speaker 2: did I miss it? I don't know.
- 10:36Speaker 3: I didn't even get out of the chair. I just
- 10:38Speaker 3: thought I'm not going to be able to see it,
- 10:40Speaker 3: and I'm just going to stay here. So you got
- 10:43Speaker 3: to see some of it at least, but... Um, yeah.
- 10:47Speaker 3: And you know, this, it ties in also with the
- 10:49Speaker 3: fact that we got so many people who still think,
- 10:52Speaker 3: why are we doing this stuff in space? Why do
- 10:54Speaker 3: we have to be up there?
- 10:55Speaker 1: What a waste of money.
- 10:57Speaker 3: And it's just rich people spending their money and they're
- 11:00Speaker 3: rich boy toys. And no, there's actual science and medicine
- 11:05Speaker 3: taking place up there.
- 11:07Speaker 2: There's all manners of use case ideas for what can
- 11:13Speaker 2: be done in the space environment and in microgravity. And again, obviously,
- 11:18Speaker 2: one of the highest priority sets of lists are those
- 11:22Speaker 2: that are biomedical experiments that have applications to people suffering
- 11:26Speaker 2: from illnesses right back here on the Earth. That's why
- 11:28Speaker 2: so many of those experiments are done up there on
- 11:30Speaker 2: the space station. But in addition to that, they're just
- 11:33Speaker 2: trying to help the astronauts themselves figure out how to
- 11:36Speaker 2: survive in that microgravity environment without some of the adverse
- 11:39Speaker 2: effects that take place on the human body while in orbit.
- 11:43Speaker 2: So all of those are really important research areas. And again,
- 11:47Speaker 2: I'm pretty sure that a lot of people simply don't
- 11:49Speaker 2: know the breadth of research that takes place on that
- 11:53Speaker 2: very important orbital laboratory, the International Space Station. So that's
- 11:57Speaker 2: one of the reasons we like to raise awareness on
- 12:00Speaker 2: this particular podcast.
- 12:01Speaker 3: More Made of Stars right after this. Another Artemis II
- 12:25Speaker 3: astronaut has stepped down from active astronaut duty, Christina Cook
- 12:29Speaker 3: this time.
- 12:32Speaker 2: I don't know why, but I'm just kind of a
- 12:33Speaker 2: fan of Christina Cook. I think when she speaks about
- 12:37Speaker 2: her time in space, it's always very inspiring. She's had
- 12:41Speaker 2: many trips to space, the Artemis II being the last
- 12:44Speaker 2: one of those. And now it looks like it will
- 12:47Speaker 2: indeed be her last trip to space in general because
- 12:51Speaker 2: Christina Koch has now taken a new role with the
- 12:54Speaker 2: National Aeronautics and Space Administration, which required her to step
- 12:58Speaker 2: down from active astronaut duty. As of October 13th, 2026,
- 13:02Speaker 2: NASA has announced that Christina Koch will serve as NASA's
- 13:06Speaker 2: next deputy chief engineer. So a very important role at NASA.
- 13:11Speaker 2: NASA officials wrote a statement on Tuesday that said this, quote,
- 13:15Speaker 2: With this appointment, Cook will transition to management astronaut status
- 13:20Speaker 2: and will no longer be eligible for future spaceflight assignments, unquote.
- 13:25Speaker 2: So it looks like the end of the active flight
- 13:27Speaker 2: career for Christina Cook, but moving into a very important
- 13:31Speaker 2: engineering oversight role at the National Aeronautics and Space Administration.
- 13:36Speaker 2: And as Wes said just a minute ago, she's joining
- 13:38Speaker 2: the other astronauts because now all four of of the
- 13:42Speaker 2: Artemis II astronauts have stepped away from active astronauting. Astronauting,
- 13:48Speaker 2: is that a word? I don't think so. I think
- 13:50Speaker 2: it is now. I mean, you know, I've coined it here.
- 13:54Speaker 2: I didn't say clone it. I've coined it here. Anyway,
- 13:57Speaker 2: Mission Commander Reed Wiseman and pilot Victor Glover became, quote,
- 14:01Speaker 2: emeritus astronauts, unquote, last month. And that role includes planning, advising,
- 14:07Speaker 2: and mentoring duties, but no space flights. Victor Glover also,
- 14:11Speaker 2: after his second flight to space, will now work full-time
- 14:15Speaker 2: at his alma mater, which is Cal Poly State University
- 14:19Speaker 2: in San Luis Obispo, California. My office mate in graduate
- 14:24Speaker 2: school went to Cal Poly. That's a really great science
- 14:27Speaker 2: and engineering school. And now Victor Glover will be working
- 14:30Speaker 2: full-time at his alma mater. So congratulations to both Reid
- 14:35Speaker 2: Weissman and Victor Glover. But what about Jeremy Hansen, the
- 14:38Speaker 2: Canadian astronaut? Well, Jeremy Hansen, the Canadian astronaut, only had
- 14:43Speaker 2: one flight to space, and that was Artemis II. However,
- 14:47Speaker 2: he was already a member of the Royal Canadian Air Force,
- 14:51Speaker 2: where he was also a colonel. And he has become,
- 14:54Speaker 2: he has left the astronautics corps of the Canadian Space
- 14:57Speaker 2: Agency and gone back to the Royal Canadian Air Force
- 15:00Speaker 2: as a reservist. This became official last month. So again,
- 15:04Speaker 2: all four now, Artemis II astronauts step away from active
- 15:09Speaker 2: spaceflight duty. So check out that story, by the way,
- 15:12Speaker 2: on space.com.
- 15:14Speaker 3: Apparently one was enough for him.
- 15:16Speaker 2: One and done. If you go around the backside of
- 15:19Speaker 2: the moon. Yeah.
- 15:20Speaker 3: I mean, that satisfies the itch. And then you go,
- 15:22Speaker 3: I think that's good. That's pretty good. They're not going
- 15:26Speaker 3: to probably let me walk around up there. So that's
- 15:28Speaker 3: probably it.
- 15:29Speaker 2: You know, it's a good one to spike the football on.
- 15:31Speaker 2: Now there's nothing to say that Jeremy couldn't come out
- 15:36Speaker 2: again of active duty as a reservist in the Royal
- 15:40Speaker 2: Canadian Air Force sometime in the future and go back
- 15:42Speaker 2: to the moon once all those Yanks get all the
- 15:45Speaker 2: process figured out. Maybe he'll just wait and just see.
- 15:49Speaker 2: There's Artemis 7 or 8 or something like that. But
- 15:52Speaker 2: these things all remain to be seen, and we'll just
- 15:56Speaker 2: keep you posted right here on the Made of Stars podcast, friends.
- 15:59Speaker 3: We try to update you whenever there are significant sunspots,
- 16:04Speaker 3: and especially when there's some with some potential for danger
- 16:08Speaker 3: and complications.
- 16:09Speaker 1: And, hey, we got one of those.
- 16:12Speaker 2: Don't forget, we are still in a window of time
- 16:16Speaker 2: near what's called the autumnal equinox, where there's something called
- 16:20Speaker 2: the Russell-McFerrin effect. which is kind of just a matching
- 16:24Speaker 2: up of the sun and Earth's magnetic fields that make
- 16:27Speaker 2: aurora phenomenon more likely. So when we have big sunspots
- 16:33Speaker 2: and big solar flares on the sun in October, we
- 16:37Speaker 2: know there's a little bit extra chance of seeing aurora
- 16:41Speaker 2: borealis as far south as Columbus, Georgia, which we did
- 16:44Speaker 2: in October of 2024. So we're keeping an eye on
- 16:48Speaker 2: a big sunspot group called AR-4551. AR, that's active region.
- 16:57Speaker 2: It's not associated with any firearms. Active region 4551 on
- 17:01Speaker 2: the sun now has developed a beta gamma delta. It's
- 17:06Speaker 2: not a sorority. It's a magnetic field classification. It's a
- 17:11Speaker 2: twisted up magnetic field classified as a beta gamma delta.
- 17:14Speaker 2: When that happens, friends, that makes these sunspot groups far
- 17:19Speaker 2: more likely to produce the strongest class of solar flares
- 17:23Speaker 2: called an X-class solar flare. And because this particular sunspot group, AR4551,
- 17:29Speaker 2: is directly in line with the Earth, there's something called geo-effectivity.
- 17:36Speaker 2: Any explosions today would be more geo-effective. In other words,
- 17:41Speaker 2: more likely to produce aurora on the Earth just because
- 17:44Speaker 2: of the alignment of that sunspot in the direction of
- 17:48Speaker 2: the Earth. So you have the alignment of the sunspot,
- 17:51Speaker 2: you have the twisted up potential of that magnetic field
- 17:54Speaker 2: on the sun, and you have the Russell-McFerrin effect because
- 17:57Speaker 2: we're near to the autumnal equinox. All of these things
- 18:03Speaker 2: bear watching. We're going to be watching tonight and through
- 18:07Speaker 2: the next day or so to see if active region
- 18:11Speaker 2: 4551 launches any giant magnetic storms in the direction of
- 18:16Speaker 2: the Earth or which could then trigger geomagnetic storms and
- 18:20Speaker 2: possibly bring northern lights down to the lower 48. If
- 18:24Speaker 2: you want to be in on the watch, check out spaceweather.com. Again,
- 18:29Speaker 2: one of our very favorite websites here on the podcast.
- 18:31Speaker 2: We like to reference them often because they have awesome stories.
- 18:35Speaker 2: So check out spaceweather.com today and watch that big sunspot group, 4551.
- 18:39Speaker 3: More made of stars right after this. We all know supernovas.
- 19:06Speaker 3: Let's talk about hypernovas. What's a hypernova?
- 19:10Speaker 2: I remember the first time that some kid who reads
- 19:12Speaker 2: the internet more than me came up to me and said, Dr. Krusen,
- 19:16Speaker 2: tell us about those hypernovas. And I had been just
- 19:20Speaker 2: my eyes off research. I'm a mid-level state manager. I
- 19:25Speaker 2: have a fair amount of just like bureaucratic paperwork to do.
- 19:28Speaker 2: So I don't always get to keep up on the
- 19:29Speaker 2: latest with astrophysics, but that's when hypernovas were first proposed.
- 19:35Speaker 2: And it was like, gosh, kid, you beat me to it.
- 19:38Speaker 2: You scoop me. Let me go figure it out. So
- 19:40Speaker 2: I read up about hypernovas and hypernovas are thought to
- 19:43Speaker 2: be the upper end of the core collapse variety of
- 19:47Speaker 2: supernovas that top sort of 10%, maybe an order of
- 19:53Speaker 2: magnitude more powerful than your average core collapse supernova. What's
- 19:58Speaker 2: an average core collapse supernova, by the way? It's when
- 20:00Speaker 2: the biggest stars fall. use up all their fuel and
- 20:03Speaker 2: their engine inside, their core actually collapses and causes the
- 20:07Speaker 2: whole star to collapse down. Then there's a massive rebound
- 20:11Speaker 2: effect and that rips the star apart. That's what a
- 20:14Speaker 2: standard core collapse supernova is, the most powerful type of supernova.
- 20:21Speaker 2: So these hypernovas were thought to be even more powerful
- 20:24Speaker 2: than that. And it turns out that sometimes ideas in
- 20:28Speaker 2: astrophysics get proposed to on some very thin evidence. And
- 20:34Speaker 2: this might be one of those cases. So the story
- 20:37Speaker 2: we have for you today from universe.com has a headline
- 20:41Speaker 2: that basically said, is a hypernova all hype and no nova?
- 20:47Speaker 2: In other words, are hypernova really a real thing? Okay,
- 20:52Speaker 2: so the evidence was this. We have found that certain
- 20:58Speaker 2: stars have extremely low quantities of of these chemicals that
- 21:03Speaker 2: we call metals in astrophysics metals and astrophysics are basically
- 21:08Speaker 2: anything heavier than lithium so it's the entire rest of
- 21:11Speaker 2: the periodic table including things like carbon and oxygen which
- 21:14Speaker 2: we don't typically think of as a metal but that's
- 21:16Speaker 2: the language we use in astrophysics so to say a
- 21:19Speaker 2: star is metal poor means that that star is almost
- 21:22Speaker 2: made up entirely of only hydrogen and helium and not
- 21:27Speaker 2: the other elements on the periodic table Well, there are
- 21:31Speaker 2: some stars that are so uniquely low metallicity that it
- 21:36Speaker 2: was thought that these stars could have been the progenitor
- 21:39Speaker 2: stars for structures in the universe that we find that
- 21:44Speaker 2: have very low quantities of these metals. And we said, okay, well,
- 21:50Speaker 2: what kind of a supernova would produce that? Well, that's
- 21:54Speaker 2: when a hypernova, a more powerful class of supernova than
- 21:59Speaker 2: we've ever seen before was proposed as the explanation for
- 22:03Speaker 2: these areas where stars could form with very low metallicity.
- 22:08Speaker 2: So it's like one of these pieces, chains of evidence
- 22:13Speaker 2: that you're extrapolating the extreme object built on the case
- 22:17Speaker 2: where you see an unusual situation in the universe. So
- 22:21Speaker 2: to say that this case relied on circumstantial evidence is very,
- 22:26Speaker 2: very true, right? So all of these tenuous, threads of
- 22:30Speaker 2: evidence led us to the idea of a hypernova. Well, now,
- 22:35Speaker 2: according to the story on universetoday.com, two new papers have
- 22:38Speaker 2: come out and they suggest that the hypernova phenomenon is
- 22:43Speaker 2: not what happens and that hypernovas aren't responsible for these
- 22:48Speaker 2: low metallicity stars. Each of these papers suggest other pathways
- 22:53Speaker 2: or other possible physical phenomenon that could lead to these
- 22:56Speaker 2: metal pore stars. which then eliminates the need for a hypernova.
- 23:02Speaker 2: And it turns out we'd never actually measured or seen
- 23:04Speaker 2: a hypernova in the act of exploding. We just projected
- 23:08Speaker 2: that they existed. So now astronomers are left today wondering,
- 23:13Speaker 2: do they exist at all? So a researcher named Anmol
- 23:19Speaker 2: Argawal from Mullard Space Science Laboratory at University College London
- 23:24Speaker 2: had this quote. all the evidence we see for hypernova
- 23:30Speaker 2: is suddenly gone. Unquote. It was a short quote. But
- 23:35Speaker 2: the point of that is now we don't need the
- 23:39Speaker 2: ending object that we had extrapolated because we found new
- 23:43Speaker 2: evidence for other causes of the actual things that led
- 23:49Speaker 2: us to the extrapolation in the first place. This just
- 23:51Speaker 2: happens in science sometimes. And so maybe... Maybe hypernovas are
- 23:56Speaker 2: not even a thing.
- 23:58Speaker 3: All hype, no nova.
- 24:00Speaker 2: All hype, no nova. You got to watch when you're
- 24:04Speaker 2: overhyping your nova.
- 24:05Speaker 3: You have to do that. And, you know, if you
- 24:07Speaker 3: maybe get to a point someday where, you know, Oasis
- 24:10Speaker 3: writes a song about a champagne hypernova, then you're legit.
- 24:15Speaker 3: I think you got to get to that stage before
- 24:18Speaker 3: you become legit at all. But that story from universetoday.com.
- 24:25Speaker 3: Let's talk about the, you guys have a new version
- 24:30Speaker 3: of an old thing coming up there at the Coca-Cola
- 24:32Speaker 3: Space Science Center. It is now called Galacticon.
- 24:36Speaker 2: Many people have enjoyed and remember our Columbus comic book
- 24:40Speaker 2: and toy show. And it's just time for a quick
- 24:43Speaker 2: hat tip. That became a thing here at Space Science
- 24:47Speaker 2: Center because one of our staff members, a good friend
- 24:50Speaker 2: of mine by the name of Dutch Cummings, was the
- 24:53Speaker 2: person responsible for establishing that program here at Space Science Center.
- 24:57Speaker 2: And earlier this week, we had to say goodbye to
- 24:59Speaker 2: Dutch Cummings. Dutch Cummings passed away, a true legend of
- 25:03Speaker 2: our team here at Space Science Center, a 25-year employee
- 25:06Speaker 2: of our museum. Galacticon is certainly something that is a
- 25:10Speaker 2: tribute to all of his work that he established. We
- 25:15Speaker 2: are going to carry on the Galacticon event. It is
- 25:17Speaker 2: happening on October the 24th. Because Dutch Cummings trained up
- 25:21Speaker 2: a whole new generation of our employees here at Space
- 25:24Speaker 2: Science Center. And that includes Mr. Clay Miller, Mr. Griffin McElroy,
- 25:28Speaker 2: and Mr. Ross Hodge, who have put together this year's Galacticon.
- 25:33Speaker 2: They did change the name. But it is effectively a rebranded,
- 25:38Speaker 2: updated version of our Columbus Comic Book and Toy Show. Friends,
- 25:41Speaker 2: if you like sci-fi, if you like hobby, if you
- 25:45Speaker 2: like collecting, if you like just hanging out with people
- 25:48Speaker 2: who love sci-fi movies... and just the sci-fi and fantasy
- 25:52Speaker 2: genre in general, this is your event. And you can
- 25:56Speaker 2: check it out a week from this coming Saturday on
- 26:01Speaker 2: October the 24th. Check it out on the website today.
- 26:04Speaker 2: If you want to find out all the information, go
- 26:06Speaker 2: to www.ccssc.org, charliecharliesamsamcharlie.org. And once again, hat tip to my
- 26:14Speaker 2: good friend, Dutch Cummings. You'll be remembered always here, brother.
- 26:19Speaker 3: Indeed, and what a great way to continue something on
- 26:22Speaker 3: that he started and for it to be an event
- 26:24Speaker 3: to continue on as a tribute to him as well.
- 26:27Speaker 3: Just a nice thing to continue that on. Sean and
- 26:30Speaker 3: I thank you for listening, and we will do this
- 26:32Speaker 3: again next week. Overhead Door Company of Columbus has all
