Term coined outside the sf genre, standing for Search for Extra-Terrestrial Intelligence – carried out by passive observation, typically using radio telescopes in hope of detecting Alien transmissions or Communications. A notable real-world effort was Frank Drake's 1960 observational Project Ozma, sited at the US National Radio Astronomy Observatory (Green Bank, West Virginia) and discussed by Martin Gardner in The Ambidextrous Universe (1964; rev vt The New Ambidextrous Universe 1990). The project name references L Frank Baum's Princess Ozma of Oz. Other such experiments range from Ozma II (1973-1976) to the distributed SETI@home project (1999-current) – which uses idle time on hundreds of thousands of Internet-connected computers to analyse radio-telescope observations – and beyond. That no indisputable positive results have ever been obtained is an aspect of the Fermi Paradox.

Science-fictional treatments of SETI, often successful and forming a preliminary to First Contact (which see) are very numerous. The prospect was discussed in Lorne MacLaughlan's article "Noise from Outside" (April 1947 Astounding). Pre-Ozma fictional examples include Gerald Kersh's "The Copper Dahlia" (October 1949 Argosy UK), Robert Crane's Hero's Walk (1954) and Frank Crisp's The Ape of London (1959).

More or less enigmatic messages from space feature in: J G Ballard's "The Voices of Time" (October 1960 New Worlds), where characteristically the signals are a count-down recording the resistless progress of Entropy; John Brunner's Listen! The Stars! (1963 dos; rev vt The Stardroppers 1972), where, once comprehended, they impart the dangerous secret of Teleportation; Stanisław Lem's Glos pana (1968; trans as His Master's Voice 1983), where (again characteristically) the content remains maddeningly ambiguous even when "understood" and implemented; Colin Kapp's The Patterns of Chaos (February-May/June 1972 If; 1972), featuring inadvertent eavesdropping on unintelligible alien communications; and Piers Anthony's Macroscope (1969; cut 1972), whose transmission is a Basilisk that destroys any mind able to comprehend it.

Further sf works centred on or interestingly featuring SETI include: A for Andromeda (1961) – setting the pattern for Trojan Horse transmissions that persuade the recipients to do or construct something undesirable; Chloe Zerwick's and Harrison Brown's The Cassiopeia Affair (1968), whose world-transforming message may be bogus; Robert Silverberg's Tower of Glass (1970); Richard and Nancy Carrigan's The Siren Stars (March-May 1970 Analog; 1971); James Gunn's The Listeners (fixup 1972) – perhaps sf's most thoughtful study of SETI as a scientific and human endeavour; Ben Bova's Voyagers (1981); Jeffrey A Carver's The Infinity Link (1984); Michael P Kube-McDowell's Emprise (1985); Carl Sagan's Contact (1985); Jack McDevitt's The Hercules Text (1986); Fred Fichman's SETI (1990); Mary Doria Russell's The Sparrow (1996); Robert J Sawyer's Factoring Humanity (1998); and Ray Hammond's The Cloud (2006).

More active forms of SETI – excluding Starship exploration, covered in various other entries – range from the involuntary spread of human broadcasting beyond the immediate vicinity of Earth (visiting Aliens who announce "We learned Earth's languages from your radio/television transmissions" have become a well-established Cliché), via the inclusion of recordings and message plaques on space probes (Carl Sagan was involved with two such efforts), to deliberate speculative broadcasting as in Fred Hoyle's The Black Cloud (1957) and Liu Cixin's Santi (May-December 2006 Kehuan Shijie; 2007; trans Ken Liu as The Three-Body Problem 2014); in the latter, an old Chinese SETI project known as Red Coast makes a highly dangerous contact with the Alpha Centauri system. A particularly extravagant example of calling attention to ourselves is the detonation of Stars as interstellar message beacons in Jack McDevitt's Infinity Beach (2000; vt Slow Lightning 2000).

A more melancholy sense that SETI is a doomed endeavour pervades such works as Lee Killough's "The Lying Ear" (in Alien Encounters, anth 1982, ed Jan Howard Finder) and Ian R MacLeod's "New Light on the Drake Equation" (May 2001 Sci Fiction). Sardonic treatments of the theme include David Langford's and John Grant's Earthdoom! (1987), whose alien transmission helpfully concludes "We come to annihilate you painfully and rape your planet"; and Charles Stross's "Maxo Signals" (25 August 2005 Nature), whose titular signals translate as "419" spam messages. Despite such occasional cynicism, the hope that intelligible signals may one day be detected remains persistent both within and outside sf. As a real-world project, SETI has been criticized on such grounds as impracticality, for example by A K Dewdney in Yes, We Have No Neutrons: An Eye-Opening Tour through the Twists and Turns of Bad Science (1997).
