Planetary Radio 5th Anniversary Show: Astronomer Geoff Marcy on Discovery of Fifth Planet in Star System

Airdate: Sunday, November 25, 2007
Running Time: 00:28:52
Listen: Windows Media | MP3

Five planets circling another star help us celebrate the fifth anniversary of the show. UC Berkeley's Geoff Marcy, leader of the exoplanet discovery team, tells us about the growing solar system at 55 Cancri. Emily Lakdawalla wonders why Jupiter's Great Red Spot is red, but she knows the Jovian storm has evolved over the years. Bruce Betts and Mat Kaplan award fifth anniversary prizes, including a fragment of a Mars meteorite, courtesy of Spaceflori.com, a signed, limited edition Star Trek: Remastered poster from Mike Okuda and CBS, and two copies of SpaceStationSim from Vision Videogames, and ask a new space trivia question.
