Scientific Americans web site just ran an article on the possibility that an earth like planet has been picked up in orbit around the star Gliese 581, 20.5 light-years away. They also think it orbits in the habitable zone. The search for new planets around neighboring stars continues to gets more interesting. Imagine a very few years ago we never dreamed that we could even detect a planet at this distance. Now the speculation is that we may be able to detect signs of life in a few more years.
