Astronomers have discovered a new planet called Gliese 581 c. It is the most Earth-like planet ever found. It orbits a star and may have habitats capable of supporting life.
NASA hopes to find 50 more Earth-like planets by the end of the decade, all of which increases the chance that alien life has begun elsewhere.
