This is a nice accompanying article linked within that one: [www.space.com]

I think that we are really too hasty to rule out life on any of the other planets (or moons) in our solar system. There are some really extreme forms of life on our own planet. It just doesn't seem plausible that just because the situation on a planet is very different from our own, means that there is no life at all. I think we need to stop looking at our own planet because it is simply limiting what could be billions of variations of life.
