Stretching Habitable

Interesting. And "only" 20 LY away. But not likely to be as habitable as the headline suggests.
US scientists find potentially habitable planet near Earth - Yahoo! News: "WASHINGTON (AFP) – US astronomers said Wednesday they have discovered an Earth-sized planet that they think might be habitable, orbiting a nearby star, and believe there could be many more planets like it in space.
The planet, found by astronomers at the University of California, Santa Cruz, and the Carnegie Institution of Washington, is orbiting in the middle of the 'habitable zone' of the red dwarf star Gliese 581, which means it could have water on its surface.
Liquid water and an atmosphere are necessary for a planet to possibly sustain life, even it it might not be a great place to live, the scientists said."
