We're not just discovering lots of extrasolar planets, we're beginning to learn what these new worlds are like. Joe Harrington is part of a team that used the Spitzer Space Telescope to determine the difference in temperature between the day and night sides of a planet that is forty light years from Earth. He describes this amazing accomplishment on this week's show. Sally Ride Science tells us about the teenager who beat a robot at arm wrestling, while Bruce Betts tells us about the night sky, introduces a new space trivia contest, and gives away another Year in Space calendar with Mat Kaplan.
