CAMBRIDGE, Mass. — What does Goldilocks want?
At least four times in the last few years, astronomers have announced they have found planets orbiting other stars in the sweet spot known as the habitable zone — not too hot, not too cold — where water and thus perhaps life are possible. In short, a so-called Goldilocks planet fit to be inhabited by the biochemical likes of us.
None of these claims are without controversy, but astronomers who are making discoveries with NASA’s Kepler spacecraft are meeting next week in California to review the first two years of their quest, which seems tantalizingly close to hitting pay dirt.
“Sooner or later, Kepler will find a lukewarm planet with a size making it probably Earthlike,” said Geoffrey Marcy of the University of California, Berkeley, who spends his time tracking down candidates identified by Kepler. “We’re no more than a year away” from such a discovery, he said.

It's long article but it's pretty exciting. We could discover the planet in our lifetime than hundreds or thousands of years from now will be the first colonized by humanity. There are a number of potential worlds only about twenty light years away.
