Earth-like Planet Discovered


For the first time, a rocky, Earth-like planet has been discovered outside of our solar system.  The planet, 500 light years away, and estimated to be roughly twice the size of Earth, is believed to be rocky, and solid, like our own planet.  Other extra-solar planets have been discovered in recent years, but this is the first rocky planet.  Astronomers believe we are on the cusp of a new era of planetary discovery.
