SETIin full search for extraterrestrial intelligenceOngoing effort to seek intelligent extraterrestrial life. SETI focuses on receiving and analyzing signals from space, particularly in the radio and visible-light regions of the electromagnetic spectrum, looking for nonrandom patterns likely to have been sent either deliberately or inadvertently by technologically advanced beings. The first modern SETI search was Project Ozma (1960), which made use of a radio telescope in Green Bank, W.Va. SETI approaches include targeted searches, which typically concentrate on groups of nearby sunlike stars, and systematic surveys covering all directions. The value of SETI efforts has been controversial; programs initiated by NASA in the 1970s were terminated by congressional action in 1993. Subsequently, SETI researchers organized privately funded programs—e.g., the targeted-search Project Phoenix in the U.S. and the survey-type SERENDIP projects in the U.S. and Australia.

The new frequency gets interference from radio telescopes in other parts of California used by the Jet Propulsion Laboratory and NASA for the Search for Extraterrestrial Intelligence project. One of the earliest examples of a Grid is the Search for Extraterrestrial Intelligence Project (SETI), a private research effort funded by NASA, the National Science Foundation, private industry, and various research organizations and charitable foundations. That would be Douglas Vakoch, resident psychologist at the Search for Extraterrestrial Intelligence (SETI) Institute in Mountain View, Calif. |
