ince 1995, more than 100 extrasolar planets have been discovered. Only one, HD 209458 b, is known to transit, or pass in front of its parent star. In a quest to document other transiting extrasolar planets, two astronomers have enlisted amateur astronomers with help from their web site.
Created by Tim Castellano, an astronomer from NASA Ames Research Center, and Greg Laughlin, an assistant professor of astronomy at the University of California, Santa Cruz, Transit Search
is searching for members of the astronomy community to lend a hand.
