More than 300 planets have been discovered circling other stars, but when will we find an Earth-sized one? Astronomer Debra Fischer describes FINDS, a new technology that may bring that day closer. Bill Nye finds a deadly bacterium in space. Emily Lakdawalla's Q&A looks back at an element of the Galileo mission to Jupiter. It's back to giving away t-shirts in the What's Up space trivia contest with Bruce Betts and Mat Kaplan.
