Could This Be The Right Planet?

Astronomers may have found the "goldilocks" planet they've been looking for. They've been using the Kepler Space Telescope to find a planet that's not too hot and not too cold, with the potential for liquid water on the surface. USA Today reports the planet, called Kepler 22-B, circles a star about 600 light years away. It is about 2-1/2 times wider than Earth and has an average temperature of 72 degrees. What they can't tell yet is what the surface of the planet is like. They don't know if the world is rocky, water-covered or something else. The Kepler space telescope discovery team announced the find at a briefing at NASA's Ames Research Center in California.
