SPACE WEEK: Every Moon, Ranked

Short Wave


Too small notes before we hit you with some hot moon takes one. Obviously, we're not talking about all one hundred and fifty moons. We picked handful from the top ten, and then we'll do a lightning round on some others. All of these bodies meet the technical definition of Moon meaning they orbit an asteroid or a planet, not the Sun. Second Note. Jennifer's list also includes a few of what NASA calls provisional moons. These are bodies that are kind of, let's say unofficial maybe haven't been studied that well or confirmed yet. Yeah. So. I want to add that the scientists that I spoke to. They said that they're probably way more moons out there that we haven't even discovered yet. Well. So cool. Okay. All right. So number ten on your list diddy moon yet say, yes is did he moon? So, did he moon it's not circling a planet. It is actually circling an asteroid it. It is very tiny. It's about five hundred, twenty, four feet in diameter and it's orbiting. The asteroid diddy. Moss in it's it's kind of part of a very cool future NASA mission, right? Yes. So did he moon is part of a really important the item mission and the item mission is like this cosmic dress rehearsal basically, NASA wants to send a spacecraft to slam into diddy moon and knock it off course. Now I know what you're thinking. It sounds pretty familiar and yes, it is essentially the plot of Armageddon. Show me. But it's a really really important mission in it's going to help us test one of the ways that we think we might be able to potentially deflect a hazardous object that might be pearling towards earth. So cool. Okay. Number six called by one expert you talk to the most underrated moon in the solar system orbiting Jupiter Ganymede Ganymede. Ganymede is such a fascinating world Ganymede is the largest moon in our solar system. It's actually larger than Mercury Ganymede is also the only moon that we've known to have a magnetosphere. Cool. Earth has a magnetosphere and it's essentially this covering this kind of magnetic shell that we have of charged particles and what it does. It actually protects us from harmful radiation. So there's tons of radiation that's generated by the sun and from interstellar space, and that magnetosphere protects us it's potentially allowed life to form. Can I tell you that I am horrified to report I thought Ganymede was a made up moon Scifi show the expanse. Oh. Yes on that. Farm on Ganymede and I'm like it was a fun made up plays I love that shout the expanse it's a great show. Yeah no can't meet is just so fascinating. So number four on your list orbiting Neptune. Triton. Yes. Triton is an absolute misfit. First of all I will say it looks just like a cantaloupe if you look at the picture. How was ranked keep going I, mean, that is, of course, the important feature. But really, what's cool about Triton is that it's essentially this kind of Pluto sized object that we believe has been captured by Neptune and now orbits the planet and temperatures on Triton and we we know this thanks to the voyager two spacecraft but temperatures on Triton have dipped as low as minus three hundred ninety one degrees Fahrenheit. Super Cold Nope nope. nope. nope things. But it's partially because it's got like this ice covered surface right and that reflects a ton of the light that it receives that it's by. Yeah absolutely. That's that's another really weird thing about Tritan on it has what's called an incredibly high Albedo. So that's basically a measurement of how much late a body reflects. and. Triton's is actually really high. It reflects about seventy percent of the sunlight. It receives I'm like in Triton I'm going to be honest with you Ganymede. But I'm like Triton right now array. Okay. Time for the top three Jennifer. Are you prepared I? Think so bronze-medal orbiting Saturn Moon. That contains the big four ingredients for life hydrogen carbon nitrogen and oxygen enceladus. Yeah. So enceladus is absolutely fascinating moon. So the Cassini mission when it arrived to observe Saturn's moons, it noticed that there were jets spewing out of ENCELADUS, right? So they actually took a detour and had Cassini swing through those jets to collect samples of that liquid into turned out to be liquid water right? I remember when that happened that was wild. That was like a big deal. Yes. Absolutely, and so it really spurred a lot of interest in enceladus. Of course, we love Europa. But enceladus is really this kind of new and exciting moon and you know as you mentioned, it has the big four ingredients for life. That's really just an incredible sign that this might be one of the places where we find life. Okay. Number two on the list orbiting Jupiter lot of Okano's and some lightning. I oh. Yes. So I will admit that I have some volcanic. I really love of volcanoes. Thank you for disclosing that conflict of interest Jennifer I have to be I have to be honest. I'm anyone who knows me knows that I absolutely love volcanoes. So naturally, I O, which is the most volcanically active body in our solar system would have to take second there are over four hundred volcanoes on the surface of Iowa and they spew jets of. Lava hundreds of miles and two space. It's really incredible. Okay. So this is the wildest thing about Iot to me is that I owe can generate like true current. Yes. So of all of the Galilee and moons of Jupiter, Iowa's actually the closest to Jupiter and so sweeps through its magnetic field and that causes it to create this electric current it can generate. As much as three million amperes, and actually this jolt of electricity is then shot back to Jupiter and it creates lightning in the planet's. Fear I mean, that's cooler than the volcanoes. Some some people would say that. Yes. Okay. Your number one moon Jennifer orbiting. Saturn. A Moon I could walk on with potentially nothing more than an oxygen. Mask Titan. So Titan. Is. The only other place that we've observed so far that has a thick substantial atmosphere. So our atmosphere of course is. Critical for life here on earth and tighten, it has a similar has a sort of similar atmospheric also mostly composed of nitrogen but the second most common gas in the atmosphere is actually methane. So right. So instead of like US having oxygen the next most abundant compound in that moons atmosphere in Titan's atmosphere is methane. Yeah. Absolutely, and you think about Earth, we have a water on earth all. Three phases of water on earth. So there's liquid and gas and ice but on Titan you have liquid methane on the surface, which is really really incredible. It's the only other body in the solar system that we've observed to have liquid on its surface, and these are rivers and lakes and seas of methane and ethane part of the reason why it's got this like, orange Gooby Hayes, around the moon. Yes. So Essay in the methane on those hydrocarbons, that kind of creates it's it's really this I feel like it's really beautiful. It's this kind of soft orangish glow. So it looks a little bit fuzzy whereas other moons that don't have an atmosphere they. They look very sharp but this is very, it's a very muted known. It's. Yeah. Beautiful I think. Yeah. So. Before we go Jennifer we had to leave out a of sweet moons. So we're GONNA do lightning round. I'm going to mention a moon from your list and you give us one moon. Moon Pinions, but moon fax perfect. That sounds great. Okay. Number Forty, one Jupiter's moon ammonia. Yes. So a Mafia is actually the object in our solar system and we aren't one hundred percent. Sure. Why beautiful reds my favorite coloreds promoted to thirty one. Okay Number Twenty Jupiter's Moon Callisto. So Callisto is thought to have the. Surface in the entire solar system. Pretty Sweet. Okay. Number eighteen and nineteen combined also Saturn Moons Atlas and Pan. Atlas and Pan Look like giant Ravioli with aerial around their equator. It's so much fun. Okay. Number Thirteen one of the two moons around Mars Phobos some phobos is a giant rubble pile on track to either fling itself into Mars or split apart in orbit on some missions. Actually proposed a pit stop on the tiny moon on our way to the Red Planet love it. Okay. Number Eleven, Maranda orbiting Uranus. So Miranda is home to Verona Rupe. It's the tallest cliff in the solar system. If you fell off its edge, you would have time to read the newspaper before you hit the ground. Okay.
