I've always loved both astronomy and biology. It makes sense then that I get really excited when the two topics are combined, such as in the search for exterrestrial life. While we have plenty of options for potentially habitable worlds in our own solar system, none of them really resemble earth. The following is a list of five planets outside our solar system that are quite earth-like and would be more likely to host life as we know it.
I'm particular interested in Gliese 581g and Gliese 581d, as they're from the same system. It seems like it would be an obvious target for further study with two potential life bearing worlds. I get the feeling gliese 581g would be more Earth like, while Gliese 581d would be more similar to Mars in terms of friendliness to life.
