How Saturn Works

Thu, 02 Jan 2025

Description

Saturn is the fanciest planet thanks to its prominent rings, cocked jauntily to the side. But this showy gem of the solar system has a lot of substance in addition to a great sense of style. Learn what makes Saturn so interesting in this episode.See omnystudio.com/listener for privacy information.

Chapter 1: What are the key features of Saturn?

115.132 - 123.722 Chuck

Yeah. And not just stuff in general. We're actually going to zero in on one specific piece of stuff that's out there in space, a little planet called Saturn.

0

124.875 - 128.399 Josh

That's right. The ringed beauty, as they like to say in the biz.

0

129.56 - 147.598 Chuck

It is, yeah. That's what the astrophysicists all call it. Yeah, Saturn does have rings. It's not the only planet with rings, as we'll see. Or we can see now, I think Jupiter and Uranus and is it Mercury also that has rings? But they're just, they don't hold a candle to Saturn's rings.

0

148.098 - 149.859 Josh

Hey, get that candle away from my anus.

0

152.781 - 172.795 Chuck

Saturn's also a really ancient planet in that as far as human experience goes, for as long as we've been looking up in the night sky, we've seen Saturn. Because it is the sixth planet from the sun, it's also the furthest planet away that you can see with the naked eye here on planet Earth.

173.857 - 197.614 Josh

want to know something funny before we go any further yeah always uh before we recorded emily was asking um as she sometimes does what we're recording and i told her the two episodes and she asked about saturn and i was like not very interesting to me she said so what are you gonna what do you do in those episodes just like do commentary and make jokes i went well there's probably not gonna be a lot of jokes

198.314 - 207.742 Josh

And she said, well, as long as you can make one about Uranus. And I said, I don't think I'll be able to because it's about Saturn. And lo and behold, a minute and 20 in. Yeah.

208.823 - 213.567 Chuck

Wow. Now you have two more times to bring it back and then you'll have completed the comedy.

214.808 - 222.494 Josh

I think that's a one or as they say, but I'm just excited to report back to Emily that that happened unexpectedly and delight delightedly.

Chapter 2: How does Saturn compare to Earth?

346.785 - 358.211 Chuck

It makes it look like a nickel if Saturn was a volleyball. NASA loves that one. If you ever look up Saturn's size, NASA uses that every chance they get.

0

359.167 - 377.629 Josh

I wonder if when they got the nickel part and they were like, all right, well, we got to find something laying around here that's as big as this distance. And some guy was like, you know, there was one sporty guy in the corner, like, practicing setting a volleyball spike. Mm-hmm. He said, what about Jim over there?

0

377.969 - 380.831 Chuck

Is that low-hanging fruit Phil who is about to do that?

0

381.511 - 396.199 Josh

Oh, man, poor Phil. But, you know, you're right. Nickel compared to a volleyball is pretty good. But let's talk equator. The equator is close to 10 times larger than Earth at 227 miles around compared to Earth's piddly little 25,000 miles.

0

401.618 - 404.861 Chuck

Yeah, it's got an extra spare tire compared to Earth's, you know?

405.301 - 405.641 Josh

Totally.

406.962 - 432.627 Chuck

One of the things about Saturn, though, if you aren't like an astronomy type, the kind of planet that Saturn is is a gas giant, which means that it's made largely of gas. Or gas is. So to be a gas giant, you don't have to just be a big ball of gas, but you're made of things that typically are considered gases on the periodic table. Let's just get that straight right out of the gate, okay? Right.

433.027 - 450.493 Chuck

But if you put the whole thing together, Saturn doesn't have a surface to speak of. If you did go far enough in toward the center- You might eventually hit something you could stand on, but you would be under so much heat and pressure that you wouldn't be thinking about standing on the surface anymore. You'd have other problems.

450.973 - 464.637 Josh

Yeah. It's a very not dense planet. And some say it could even float in water if there was water that large. A pool? Yeah. Or, I don't know, a pond?

Chapter 3: What is Saturn's atmosphere like?

470.55 - 472.771 Josh

You know, I don't know the difference between a pond and a lake.

0

473.292 - 474.692 Chuck

In Maine, there is no difference.

0

475.273 - 481.896 Josh

I would think a pond is human-made, but there are many human-made lakes, too. So, I don't know. I'll have to look that up.

0

482.176 - 497.185 Chuck

I always assumed it was size. Like, pond is smaller. Lake is larger. Well. That's how you remember. Lake, L, large, L. And pond, puny. Nice one.

0

498.545 - 503.948 Josh

I mean, that seems obvious, but surely there's something else. But maybe not. We'll look into that. More to come on ponds and links.

504.148 - 505.588 Chuck

Okay. I'll keep talking while you look.

508.77 - 533.644 Josh

I was going to talk. So why don't you look it up? Earth is the third planet out, as Modest Mouse will tell you. They're about 92 million miles away, or we are rather. Saturn is the sixth planet away from the sun. And things really pick up after you get away from Earth. 886 million miles away. which is going to mean they're going to be a very cold planet because they get not nearly as much sun.

533.664 - 543.934 Josh

They get about 1.2 percent of the sunlight that we get, which means the average temperature in the upper atmosphere of Saturn is a very chilly negative 220 degrees Fahrenheit.

544.294 - 563.431 Chuck

Or negative 140 Celsius for our non-American Liberian or I can't remember the third one, friends. That's right. So there's some other interesting things that happen because it gets such little sunlight. But one of the things that astronomers were surprised by at first was Saturn's atmosphere.

Chapter 4: How did Saturn form?

1507.912 - 1527.663 Josh

We're talking 500 mile an hour winds at the center of this vortex. And they think that weird shape is due to the really fast rotation, which makes a bulge at the equator and flattens things out at the pole. So it's just created this really strange kind of jet stream, this strange shape.

0

1527.783 - 1537.149 Chuck

Yeah. So I think, Chuck, we can't really put it off any longer. I believe that it's time to talk about Saturn's rings. Because, I mean, imagine if we didn't in this episode.

0

1537.97 - 1560.887 Josh

Yeah, I mean, you mentioned, you know, it's not the only one with rings. I know you mentioned my anus. Sorry. That's three. I know. That's the lowest of low-hanging fruit, though. Phil would be like, it's fine. Yeah, Bill would love it. But Neptune and Jupiter, I'm not sure if you mentioned those. Those are some other ringed planets. But Saturn's are like those are the showstoppers.

0

1562.087 - 1573.889 Josh

They're incredible. If you've ever, you know, do yourself a favor. If you've never looked at like real pictures, like telescopic pictures of Saturn, like do so because it's incredible looking. These pictures.

0

1574.229 - 1594.594 Chuck

I have I have an anecdote about that. Let's hear it. So remember, we did an Australian tour a few years back. It was great. Yeah, it was. On one of the days off, Yumi and I went to the Sydney Observatory one night. Oh, cool. And they just happened to have one of their telescopes trained on Saturn. And you could lean over and look through the eyepiece. And we did.

1595.295 - 1617.97 Chuck

And both of us just started laughing because it looked amazing. So fake, like a little white cutout of Saturn, just flat as could be. It just looked like they were like, we can't find Saturn. So we're going to have to put this slide in there. But the volunteer was looking at us like, what are you what's so funny about Saturn? Basically, we just moved along.

1618.03 - 1620.532 Chuck

But that was our that's my Saturn anecdote.

1621.072 - 1623.354 Josh

And you said it looked fake. And he's like, that's real, man.

1624.354 - 1627.917 Chuck

No, we didn't. We didn't bother to say anything. It was mine and Yumi's little joke.

Chapter 5: What are Saturn's rings made of?

Chapter 6: What interesting weather phenomena occur on Saturn?

Chapter 7: How does Saturn's rotation affect its shape?

1135.97 - 1160.429 Josh

All right. So there are a couple of theories about how Saturn was formed. If you're a regular human walking around planet Earth, you might hear both of these and say, sounds like you're kind of talking about basically the same thing. Yeah. If you're an astrophysicist, you might glaven out, as you mentioned before. That's two glavens. And say, oh, no, no, no.

1160.949 - 1184.433 Josh

It is a very polarizing question in astrophysics and to us. This difference is very large. So, yeah. So if you're an astrophysicist out there, this might really excite you. If you're not, I would I would dare you. I would urge you to try and be delighted in the minutia of the difference of science and how important that can be.

1185.246 - 1192.807 Chuck

The question about how Saturn or gas giants like Saturn form is more polarizing than the proposal to rename Uranus.
