Life in the Universe

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 answers, when they come, could transform our world. Since the day it was formed in 1980, The Planetary Society has been there to support the search.

And what about other life? Is there -- or was there ever -- anything else alive in our solar system? Did microbes once spring to life in oases on early Mars, or around the undersea volcanic vents of Europa or Enceladus?  Could life have originated on Mars and been transported to Earth? We've never detected evidence for anything living elsewhere than our own fragile planet. Are we alone?
