A Third of Sun-Like Stars May Have Warm Earth Analogs 188
The Bad Astronomer writes "An astronomer studying data from the first 136 days of the Kepler observatory missions has calculated that as many as 34% of all Sun-like stars (abstract) may have Earth-sized planets orbiting in their habitable zones, where conditions are right for life as we know it. I have some reservations with his numbers, but they do match other studies. There may be 15 billion warm, Earth-sized worlds in our galaxy alone."

15 billion, but 0 within reach... So much for that info.

That's the whole "as we know it" part.
It's not that anyone thinks its impossible for life to from under other conditions, but that we do know of one set of conditions that worked. Plus, I always thought habitable meant habitable for humans.
