  • SETI Institute - The mission of the SETI Institute is to explore, understand and explain the origin, nature and prevalence of life in the universe.

  • SETI@home - SETI@home is a scientific experiment that uses Internet-connected computers in the Search for Extraterrestrial Intelligence (SETI). You can participate by running a free program that downloads and analyzes radio telescope data.

  • The SETI League - The SETI League, Inc. is participatory science. We are the international grass-roots organization dedicated to privatizing the electromagnetic Search for Extra-Terrestrial Intelligence.

  • Search for Extraterrestrial Intelligence, Planetary Society - 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.

  • The Columbus Optical SETI Observatory - The Search for Extraterrestrial Intelligence (SETI) in the Optical Spectrum - looking for monochromatic and pulsed laser beacon signals.

  • SETI, Wikipedia - Visiting another civilization on a distant world would be fascinating, but at present is beyond human capabilities (see Project Orion and Project Daedalus for some hypothetical explorations of the concept). However, it is perfectly within reach to develop a communications system using a powerful transmitter and a sensitive receiver, and use it to search the sky for extraterrestrial worlds whose citizens have a similar inclination as terrestrials.

  • Optical SETI at Harvard - A high-intensity pulsed laser, teamed with a moderate sized telescope, forms an efficient interstellar beacon. Using only "Earth 2000" technology, we could build such a laser transmitter. To a distant observer in the direction of its slender beam, it would appear (during its brief pulse) a thousand times brighter than our sun.

  • SETI Australia Centre - Educational science articles from the sky survey conducted at the Parkes radio telescope in Australia.
