Dr. Seth Shostak sees the search for alien life as a three-horse race, and not a long one either.

Seriously, why we haven't met a martian yet is beyond me. Mars is literally throwing itself at us in support of the case for life.
So far, our search for Martians and other extraterrestrial forms of life hasn't quite panned out, but that doesn't stop us from continuing to look. Now astronomers at the University of Hertfordshire in England have discovered a new system of planets, which in many ways are remarkably similar to our own neighborhood and may even support life.
