Are we alone?

Is anyone talking?

Is anyone listening?


The Search for Extraterrestrial Intelligence is a quest to answer one of life's most intriguing questions: Are we alone in the universe?

Yes or no, either answer will have tremendous implications for mankind.

Should the answer turn out to be YES, we are alone, then our race would be placed in a position of being the only creatures in existence capable of exploring such questions. We would be the supreme and only intelligence in the cosmos. A staggering thought.

If the answer turns out to be NO, we are not alone, then who else is out there? What are they like? What knowledge do they have? How do they act towards other races? What are their philosophies, sciences, and arts? The questions are endless, as are the possibilities.

We have the technology to communicate over vast distances - millions of lights years. We are capable of sending and receiving radio signals across the vast expanses of space. Actually we have been sending them for over half a century. All radio, television, and radar signals from Earth leak out into space and spread across the galaxy.

Perhaps some other advanced civilization has detected our signals and is now sending their own in an attempt at communication. The only way we'll know is to look and to listen.

That is exactly the premise behind SETI (The Search for Extraterrestrial Intelligence). The idea is to listen, using radio telescopes, for radio emissions from other worlds.

Come and listen with us.
