‘NASA has found a planet outside our solar system that looks to be an awful lot like Earth–or maybe even better, given that its climate is roughly like a balmy day in Key West.

The planet, Kepler-22b, is the first confirmed planet within the “habitable zone,” meaning that liquid water could exist on the surface and support life. It is almost 2.5 times the size of Earth and 600 light years away, so you may want to start saving your frequent flier miles now if you want your great-to-the-29th-power grandchildren to have a shot at vacationing there.’ (via CNET).
