Rings Around a Comet, Betelbuddy, and Odd Jupiter Moons

from Walkabout the Galaxy · host Josh Colwell, Jim Cooney, Audrey Martin

These rings aren't around Uranus, they're somewhere even more odd. We discuss the mysterious and changing ring system around the Centaur object Chiron, new clues about the origin of the solar system from the irregular moons of Jupiter, and the puzzling stellar companion to Betelgeuse. Plus, top quark Jim Cooney stumps us with trivia.
