NASA's Unexplained Files
For centuries, mankind has looked to the skies and wondered, "are we alone in the universe?" In one month SCIENCE partners with TED and SETI Institute (Search for Extraterrestrial Intelligence), to enlist like-minded individuals everywhere to tackle this defining question with ARE WE ALONE?, a breakthrough multimedia initiative. ARE WE ALONE? is timed to support a major new resource called SETI Live which will empower and mobilize "citizen scientists" from all walks of life to join the search for extraterrestrial intelligence.
