Steve Vogt, UC Santa Cruz Professor of Astronomy and Astrophysics, describes his search for extrasolar and Earth-like planets at the Lick Observatory.
"The first habitable planet that we’ve found, Gliese 581G, is right dead-on inhabitable on orbit. It’s a place of refuge from the — the unbelievable harshness of the universe. A place where you could stand and not, you know, fly off into space, where there would be gases to breath, water that would pool in liquid form, maybe oceans. Whether there’s something living there or not, we don’t know."
