Episode Details

Saturn's rings are so amazing that they have helped us learn that Saturn's core is a sludgy-soupy beast that doesn't have a sharp boundary. And the waves in the rings are like the Milky Way's spiral arms, one of which has a clump at an odd angle that may be similar to some clumps we see in Saturn's rings! The astroquarks are here to help you fit it all together. Plus, how fast can you walk on the Moon? You might be surprised.
