1. Planet Quest: A Historic Timeline of the Search for Other Worlds

    NASA’s Planet Quest website presents a Historic Timeline of the search for other worlds. The Timeline is a continuously updated Flash interactive that records 2,000 years of milestones in the search for exoplanets, done in a rich visual style. It serves as a primary source for members of the general public looking for information on the history of exoplanets, as well as for teachers in classrooms, educators in museums and science centers, and even scientists looking to round out their next talk!
