A Sea Under the South Pole of Enceladus?

Airdate: Monday, April 2, 2007
Running Time: 00:28:52
Listen: Windows Media | MP3

Planetary scientist Geoffrey Collins thinks there may be a liquid water sea under the surface of Saturn's little moon Enceladus. He talks about this theory and his fascination with other icy moons in our solar system. Emily Lakdawalla reports that Enceladus' geysers interfere with our ability to determine Saturn's rate of rotation. And it's a weird week of way-out wonder on What's Up, as Bruce Betts and Mat Kaplan award another t-shirt and announce a new space trivia contest.
