Today NASA’s Kepler Mission confirmed the discovery of the first planet outside our solar system that might be able to support life as we know it. Dubbed Kepler 22b, it orbits around a star very like our Sun and within the “habitable zone” where water could be in liquid form on the planet’s surface.
“This is a major milestone on the road to finding Earth’s twin,” said Douglas Hudgins, Kepler program scientist at NASA Headquarters in Washington.
It’s almost 2-1/2 times the size of Earth, so there’s lots of potential real estate available there. One slight complication–it’s about 600 light years away so you better get a move on if you want to be the first one there.
