Wesley Traub describes how scientists have succeeded in their quest to find new planets, what they have seen so far, and how they will look for life on these new worlds. Less than a decade ago, the only planets known to exist were the nine of our solar system. Now astronomers have found more than 100 worlds around other Milky Way stars. Most are Jupiter-sized, but Earth-sized orbs may be hiding nearby.
