Emily Lakdawalla tells us about the amazing images of Enceladus just taken by the Cassini spacecraft. You have to see them to believe them. Then Glen Cushing of the US Geological Survey talks about his discovery of giant lava tubes on Mars. Could they hide signs of past life? Bill Nye returns to his regular commentary while Bruce Betts joins Mat Kaplan for a What's Up! night sky tour, the awarding of a Cosmos 1 Solar Sail jacket, and a new space trivia contest.
