Diving Europa with the Makers of Under the Sea 3D and Lonne Lane

Howard and Michelle Hall's stunning new IMAX film Under the Sea 3D premieres this week. We sit down with them and JPL's Lonne Lane to talk about how we'll someday explore a different ocean, the one under the ice of Jupiter's moon, Europa. Bill Nye on reaching another hidden body of water under the Antarctic ice. Q&A on fluids other than water that might support life. Bruce Betts and Mat Kaplan with What's Up and a new What's Up space trivia contest.
