Astronomers have just announced findings that have reshaped understanding of our home galaxy. Bob Benjamin and Thomas Dame join us to explain. Emily Lakdawalla provides a Phoenix Mars mission update as water ice is confirmed at the landing site. Bill Nye has his own enthusiastic take on Martian water, and Bruce Betts avoids the dentist with Mat Kaplan on this week's edition of What's Up, including a new space trivia contest.


No trivia contest spoilers please!
