SETI Institute at a Glance

The Institute employs about 130 people, primarily scientists, in a variety of fields including all science and technology aspects of astronomy and the planetary sciences, chemical evolution, the origin of life, biological evolution, and cultural evolution.

SETI History

SETI, the Search for Extraterrestrial Intelligence, began early in the Space Age. Only two years after the launch of Sputnik, two physicists at Cornell University, Philip Morrison and Giuseppe Cocconi, published an article in the journal Nature in which they noted the relative ease with which radio messages could be sent between the stars.

The Future of SETI Research

The scientific Search for Extraterrestrial Intelligence (SETI), which began with a simple experiment forty years ago, is undergoing rapid change. Scientists who participate in this research are more optimistic than ever before that they could find signals from space that would indicate that we're not alone.  

Allen Telescope Array Fact Sheet

The Allen Telescope Array (ATA) is a joint effort by the SETI Institute and the Radio Astronomy Laboratory at the University of California, Berkeley to construct a Radio Interferometer that will be dedicated to astronomical and simultaneous search for extra-terrestrial intelligence observations.
