The Moon's Origins and Titan's Mysteries

All summer long, we've been on a 10-episode odyssey through the changing universe (check out the series). But there was one big set of objects that we skipped over: moons. So now we're back, with special guest, Radiolab's Latif Nasser, to talk about yes, our moon — and the many moons and quasi-moons beyond it. Where did our Moon come from? How many moons are out there? What's this "quasi-moon" of which we speak and why is it "dancing" around space?

Also, Latif tells us about Radiolab's contest to name a quasi-moon. Read all the details and submit a name here!

Lunar questions or otherwise celestial musings you think we should cover? We'd love to hear about it! You can reach us by emailing shortwave@npr.org.
