The astroquarks, Josh, Addie and Jim, return from a break to catch up on the latest planetary and galactic news.

Listen in to hear why strange quark Josh prefers the moniker "Egotron". Charm quark Addie fills in on the latest rocket news and mishaps. That, plus a new census on the number of galaxies in the early universe shows ten times more than previously thought. Top quark Jim tells us why that's no big deal.
