Scientists have been looking for extra-solar planets for decades, but only recently, with better equipment and improved techniques, have they finally unveiled new and unusual planets. Since 1995, over 155 planets have been discovered orbiting stars other than our Sun. This video segment, adapted from a NOVA television broadcast, gives an account of the discovery of the first confirmed extra-solar planet, a Jupiter-sized giant orbiting the star 51 Pegasi, and discusses the search for other extra-solar planets. The segment is three minutes nine seconds in length.
