Potentially habitable Earth-like planet discovered 31 light years away

What was once considered pure fantasy in movies like "Avatar," is now looking a little more plausible. Earlier this week, NASA announced the discovery of a possible Earth-like planet, located just 31 light years away - a hop, skip and a jump in cosmic terms - that may be able to support life. "I think it's an amazing discovery," Lisa Kaltenegger, from the Carl Sagan Institute at Cornell, said. "We have a small mission called 'Tess' that's scanning the whole sky, where the brightest and closest objects are, to find planets like ours and this is the first one."
