Cool nerdy stuff

I had read a couple of years ago where the astronomers had postulated that one of the ways they could eliminate looking for life in barren solar systems is to basically look at stars that have slight wobbles to them - the idea being that stars that wobble do that because they have planets circling them.

Well, the European astronomers have just found a solar system with three terrestrial planets circling a star.

They're also saying that one star out of three has terrestrial type planets. Nothing that humans can necessarily live on, but the possibility of life on other planets is starting to look a little more probable (my thoughts, not theirs).

Thought it was just cool.
