I don't know about you, but this is pretty exciting news for me, especially observing the artist's impression. These things help me to see just how 'small' we are in a very large universe.:
"This is the smallest extrasolar planet yet detected and the first of a new class of rocky terrestrial planets," Paul Butler of the Carnegie Institution in Washington said in a statement. "It's like Earth's bigger cousin."
Geoffrey Marcy, professor of astronomy at the University of California, Berkeley, added: "Over 2,000 years ago, the Greek philosophers Aristotle and Epicurus argued about whether there were other Earth-like planets. Now, for the first time, we have evidence for a rocky planet around a normal star."

There's a special project, already active since some years ago, that has the ambition of finding earth-like planets in other solar systems. Analyzing the small anomalies caused by the presence of an orbiting planet on it's star, the scientists were already able to classify hundreds of worlds orbiting in the so called "Life zone": an average distance similar to that of our planet from the Sun. The problem is that, at the moment, our instruments can only detect relatively large planets that are not so likely to be suitable for life as we know it (most are small gas giants).
