Christophe Lovis of the Geneva Observatory led the team that recently found a three-planet system not far from our own. The third planet is in the so-called 'habitable zone.' He talks about the discovery on this week's show. Emily Lakdawalla's Q&A is about the metal in stars and planets, and Bruce Betts announces a new space trivia contest on What's Up!
