In March, NASA launched the Kepler space telescope. It's delivering astounding results: discoveries include a planet with the density of styrofoam and objects that are hotter than the star they orbit. Astronomers are excited and baffled by some of these revelations. The Kepler telescope's goal is to find another Earth - a habitable planet like our own. The amazing discoveries so far have astronomers very excited about the possibilities. The data is streaming in and being analyzed, but so far it's only the tip of the iceberg.
