Could be the real thing after all.

Also interesting:
Another advantage for potential life on Gliese 581g is that its star is “effectively immortal,” Butler said. “Our sun will go 10 billion years before it goes nova, and life here ceases to exist. But M dwarfs live for tens, hundreds of billions of years, many times the current age of the universe. So life has a long time to get a toehold.”
And then:
“The fact that we found one so close and so early on in the search suggests there’s a lot of these things,” Butler says. Only about 100 other stars are as close to Earth as Gliese 581, and only 9 of them have been closely examined for planets. Odds are good that 10 to 20 percent of stars in the Milky Way have habitable planets, Vogt says.
