S.E.T.I.
Could humans be the only intelligent beings in all the
vastness of the universe? Or are we just one humble race, a member of a vast
intergalactic fraternity of advanced civilizations? SETI, the Search for
Extraterrestrial Intelligence, is the scientific quest to answer these great
unknowns. As of now all we have are questions, but we know the the answers, when
they come, could transform our world. For the past 25 years, The Planetary
Society has worked hard to make sure we never stop seeking these answers.
