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?

If you were a member of an alien civilization trying to communicate across the immeasurable distances of space, how would you go about it?

One of the youngest off-springs of SETI@home has been getting a great deal of attention recently. Known as the Quake-Catcher Network (QCN), this distributed computing project makes use of thousands of volunteers' computers to locate and track earthquakes.

In the beginning was SETI@home, the first large-scale volunteer computing project, launched in 1999 with seed money from The Planetary Society. Within months the project had millions of volunteers around the world joining to form the most powerful computer network ever assembled.

A fully formed planetary system, with five different planets of varying sizes and orbits has been found, orbiting a star more than 40 light years away. Significantly, it is the very same star, 55 Cancri, that was one of the chief targets of the SETI@home reobservations at Arecibo in March 2003.
Fifteen years ago, Society members and passionate space advocates like you helped save the Pluto mission. Now we can do the same for missions to Europa and Mars.
