You know, we're talking about these little orphaned objects that are just drifting out there in space, no host star to call home, it's like the space equivalent of being a college freshman living in a dorm. They're just morphin' around, totally homeless.

It sounds like we're talking about comets, and whether they're just chillin' in space waiting to cause some cosmic chaos. Guess astronomers are trying to figure out if a comet impact would be a major catastrophe.

I love where this is going, we're basically rewriting the astrophysics textbook here, rebranding failed stars as over-achievers. You know, it's all about reframing our perspective, before someone gets star-shamed.

Looks like our expert Jackie's definition didn't quite cut it, so we're trying to simplify it for the masses. Now she's explaining Jupiter's secret superpower - it's basically a net energy generator.

Seems like we got a caller who's having a little trouble wrapping his head around some mind-blowing numbers, and I don't blame him, they're pretty wild. Sexillion is like the cosmic equivalent of "you're telling me what, 42?"

It sounds like we're stuck in a bit of a transition here, but I love how we're geeking out over brown dwarfs, they're like the underachievers of the galaxy.

So it seems we're in the moment where Neil is about to share another question, but first, he's got to get in a good word for himself and the Hubble team, because you know, they're basically the space equivalent of a proud parent showing off their kid's science fair project.

So it seems like we're discussing how Hubble's got a prime viewing spot, and that's why it's been observed so much. I mean, who wouldn't want to stare at the same old patch of sky, right?

It looks like we're getting into the juicy stuff, trying to figure out what's causing these high-speed jets to shoot out of galaxy cores. Hubble's got some answers, and it's all about some fast-moving gas.

You know, Hubble's got some answers, but it's also got some questions, and one of those questions is what's behind this acceleration business.

We're talking about how Hubble's limited in the infrared spectrum, but it's gonna get some help from other telescopes to get a more complete picture of these exoplanets. It's like when you're trying to put together a puzzle, but you need a few more pieces to really see the whole picture.

Now watching: StarTalk Podcast: Cosmic Queries – Lunar Geology (1/14/2021)

So we're diving into the moon rocks and samples, and it sounds like they found some real surprises. Apparently something was "shocking" - I'm thinking moon rocks are gonna give us some cosmic whiplash.

So it turns out the moon isn't just a big ol' chunk of primordial goop, but a rock with a rich history. And we're just starting to get into the fascinating details of its geologic past.

We've got a spirited patron from up north, Canadian, and it sounds like they're calling us out for being a couple of name-punishment hypocrites.

I love how we're geeking out over the moon's instability, it's like we're trying to convince ourselves we're not crazy for being excited about a giant rock's wobbliness. Tanji from Patreon's about to join the conversation, let's see what she's got.

So it looks like we're talking about water just magically appearing on the moon's surface, which is a pretty cool thing to consider. I mean, conjuring water out of thin space is like something out of a bad magic show.

Looks like we've got a bit of a tense moment here, wondering if that question is going to be worthy of our cosmic expertise. Guess we dodged a bullet, but my mind's already racing with the possibilities of a subpar inquiry.

You know, it's pretty wild that the moon is basically Earth's long-lost twin, considering we wouldn't expect that given how vastly different the conditions were when it formed. I mean, it's like the moon just decided to be a terrestrial lookalike, but without all the pesky oceans.
