People have long gazed at the sky and wondered if there were other worlds&#x2014;Earths&#x2014;in orbit around the distant stars.  Since the 1992 announcement of pulsar planets by Alex Wolszczan, more than 130 giant (Jupiter and Saturn size) planets in orbit about nearby stars have been discovered using ground-based telescopes. In 2007, NASA's Kepler Mission will begin the space-based search for extrasolar planets. Over its planned observing lifetime, Kepler is likely to discover many hundreds of extrasolar planets both large and small. ...
