This undated handout artist rendering provided by Lynette Cook, National Science Foundation, shows a new planet, right. Astronomers have found a planet that is in the Goldilocks zone _ just right for life. Not too hot, not too cold. Not too far from its sun, not too close. And it is near Earth _ relatively speaking, at 120 trillion miles. It also makes scientists think that these examples of habitable planets are far more common than they thought.
