Its always interesting to discover a new exo-solar planet, and even more intriguing to spot another "Super-Earth". Of the dozen rocky Exo-planets discovered so far, my best hopes at the moment is Gliese 581, which is a very good candidate for life. Its mass is about 5-10x that of Earth, and it lies within the habitable zone of its host star. I do believe the chances of life are actually decent, but rare to develop into complex sentient life, not only that the bar has been raised recently, since I believe they found a gas giant in a stable orbit around a star, in a triple star system. EDIT: I forgot to mention, I remember reading in an article a while back that larger rocky planets in those ranges actually have a better chance to support life then a smaller rock like Earth. ( I believe it has something to do with its magnetic field being larger for more protection, and something else.)
