I am fascinated by the search for extrasolar planets and therefore the ultimate prize the discovery of second Earths and with them life. It has been an interesting journey. It has only been since the late nineties that people have stopped questioning if any other planets outside the solar system existed, and early examples seemed to force doubt to if any Earth like planets existed.
The race is now on to find them as the technology gets better. A couple of days ago Cosmic Log posted an article about it. One my favorite aspects of that blog is the many hundreds of comments that some articles receive. This one goes with the above linked article.

There are so many ways to take this comment, it is funny and biting and could be interpreted from many perspectives.
Mathematically they are out there, and it is only a matter of time before we find one. What changes when we do?
