In 2010, one new exoplanet appeared every four days or so; by the end of the year, the total topped 500. But in September, a truly exceptional find punctuated this steady drumbeat of discovery: the first alien planet that could host life on its surface. Gliese 581 g...
Thanks Dallas59! The rate of new discovery will jump as new capabilities become operational, and new techniques are tried.

Wouldn't one expect to find the Goldilocks Zone in the constellation Ursa Minor?
Sure - Ursa Major, Ursa Momma, and Ursa Minor are all in the same area.

Gliese 581 g, spotted by a team led by Steven Vogt of the University of California, Santa Cruz, inhabits a "Goldilocks" zone around its host star, a band just warm enough to boast liquid water. Two words: FLARE STAR.
Anything living there is going to get toasted, because the planet is going to be tidally locked, the warm side facing a star that fires mass ejections and hard radiation all the time.
The cold side is gonna be frozen.
Earth is rare in the galaxy, maybe unique. And I say this after 400+ star systems with planets discovered in our galaxy, NONE anything like ours. Keep looking, though.
To: backwoods-engineer
One also has to consider that even if we found a planet similar to ours, the likelihood of humans, or beings similar to us being there would be VERY remote. We’d be lucky if the planet even had dinosaur like creatures on it.
Heck... If someone a long time ago, in a galaxy far far away were to just randomly look at the Earth, they probably wouldn’t have found humans HERE. Our planet is 4.5 billion years old, and we’ve been here but only around 200,000 of that, which is virtually ‘no time’ in the grand scheme of things.
It all boggles the mind if you stop and think about it long enough.

Anybody remember the formula they made up for Star Trek to explain why there were so many alternate Earths?
