"Strange Planetary Vistas From Kepler" With Dr. Josh Carter

The study of extrasolar planets has recently entered its heyday with the launch of NASA's Kepler mission. 

Kepler has found that planetary systems are very common in our galaxy. Along the way, we've been surprised by the diversity of planetary systems, many of which bear little resemblance to our own solar system. Josh Carter presents these most alien of alien worlds, including planets orbiting two suns and a planetary system with two very different planets very close to one another.
