Scientists discover Earth sized planet
Today, scientists announced the discovery of the exoplanet Gliese 581 e, roughly 20 light-years away in the Libra constellation. It is approximately 2-times Earth's mass, making it the lightest exoplanet ever discovered. Although Gliese 581 e is considered too close to the system's star to support life as we know it, another planet in the system, Gliese 581 d, has an orbit that is said to be within the habitable zone:

Hey ufoblogger. Unless I'm wrong, wasn't Gliese already annouced last year? I think it was.. unless they're calling all earth-like planets "Gliese xx"
On another note, that convention for alien disclosure? How JUVENILE! I believe strongly in the presence of extraterrestrial life, but come the hell on.
"Obama better disclose by May 31 or else another country probably will before then.."
So, let me get their logic straight: American disclose what you know about UFO's because we'd rather hear from you than another country that we know will "probably" disclose before then? What? Really? How's that work?
"Oh, and we'll be reconvening in April 2010." Ah.. for what? To say that another country will probably disclose before the US does?
I believe in ET as much as the next person, but to be honest, these guys sound SO desperate. Why don't they put that energy into feeding the poor? That's pretty important is it not? They just want to satisfy their curiosity. That's all.
The planets in the Gliese 581 system are designated with letters, such as E or D.
Gliese 581 E was just discovered yesterday. E is a bit too close to the system's sun to be a habitable temperature (they think), althought the star, Gliese 581, is a Red Dwarf and is probably a lot cooler than our Sun.
You're probably thinking about the planet 581 D, which is actually around 44-times the size of earth, but falls within a habitable orbit. Liquid water may be possible on D, but not E.
