Kepler 47

NASA recently announced the discovery of a binary star system, dubbed Kepler 47 after the spacecraft that found it, that is 5,000 light years away.  Kepler 47 is particularly interesting because it has at least two planets, one of which orbits solidly within the system's habitable zone.

That planet is a gas giant, so it's unlikely to support life.  A large moon, however, might, as could a rocky planet nearby.  The discovery is important because it suggests life could arise on a planet in a binary system.  Since most stars are in multiple-star systems, if life could exist in those systems, the number of possible abodes of life would be greatly expanded.
