First distant planet with Earth-like conditions discovered

The conditions required for a world to be inhabitable like our own make finding one nearly impossible. It has to be a certain distance from the sun, there's the atmosphere to consider, air quality, number of moons — well, you get the idea. Amazingly, we may have just found one.
Astronomers Steven S. Vogt of the University of California, Santa Cruz and R. Paul Butler of the Carnegie Institution of Washington lead the teams behind finding Gliese 581g (pronounced "Gleeza"). "It's been a long haul," said Vogt. "This is the first exoplanet that has the right conditions for water to exist on its surface."
Gliese 581g is three to four times the size of Earth and orbits its dim red star, Gliese 581, every 37 days. That puts it 14 million miles away from the star in what's termed the Goldilocks zone, where the planet is just the right distance for it not to be too hot or too cold. This varies from star to star, mind you — all life would probably be burned from the Earth's surface if we were that close to the sun.
"This is really the first Goldilocks planet," remarked Dr. Butler. Fellow astronomers still need to confirm the find, but if it's as good as the pair thinks than it could be the first potentially habitable world ever to be found. The only problem? It's pretty far away. Like, damn far. We're talking 20-light-years-away far.
There's also the fact that two of the half dozen other planets orbiting Gliese 581, which is a third of the mass of our own sun, have been put forth as possible Goldilocks candidates, according to the New York Times:
Two of Gliese's planets have already had their moment in the limelight as possible Goldilocks planets. One, known as Gliese 581c, circles just on the inner edge of the habitable zone and was thus thought to be habitable three years ago. But further analysis suggested that the greenhouse effect would turn it into a stifling hell. Another planet, just on the outer edge of the Goldilocks zone, is probably too cold.
"One is on the hot side, the other is on cold side," Dr. Vogt noted, with Gliese 581g being between these two. "It's bookended."
There may never be a manned expedition to Gliese 581g, but its potential for harboring or supporting life gives astronomers hope that there are more such planets out there that we haven't discovered yet because we're still limited by our technology. Make no mistake, dear readers, there are still a lot of worlds out there for us to see.
Still, who's going to volunteer to be frozen and shipped off to Gleeza? Let's see some hands!

Quite a discovery for human civilization--didn't except us to discover one so quickly.
(I'm actually pleasantly surprised and quite excited at this moment, just my post isn't conveying said emotions.)

Not much we can do about it now. Considering once we do get going there are billion upon billions of planets that might be habitable out there.

Re: First distant planet with Earth-like conditions discovered
Well, we still have a long way before the Earth's final demise, though I surely wouldn't want to go all the way to the planet for nothing, unless if it was truly proven to be inhabitable.
Don't want to be turned into one of those Geth corpses.

Well if there is life then we would probably not be able to live there openly anyways. Foreign particles and bacteria in the air would probably make is go into an allergic reaction. But I guess by then we would have the science to fix that problem, maybe.

Re: First distant planet with Earth-like conditions discovered
I would hope so, by that time, unless lobbyists are successful at preventing cell research.
Re: First distant planet with Earth-like conditions discovered
I don't think it will have anything to do with stem cell research. These new organisms would be entirely different from us. Probably all the way down to the molecules that make them.

Re: First distant planet with Earth-like conditions discovered
I thought that would involve the study of cells and such--well, I suppose people wouldn't oppose a 'cure' or inhibitor for allergy symptoms, if we're all not with allergies by then.
Re: First distant planet with Earth-like conditions discovered
Assuming they have cells as we know them.
