SETI Institute

The SETI Institute is a nonprofit research organization founded to conduct scientific research on the nature and prevalence of life in the universe. It operates the Allen Telescope Array and conducts observations aimed at detecting signals from extraterrestrial civilizations, while also studying the conditions necessary for life to emerge and persist.

The institute combines radio astronomy, planetary science, and astrobiology to address fundamental questions about humanity's place in the cosmos. Its work includes both direct searches for technosignatures and broader research into biosignatures and habitability. The SETI Institute has become a leading institution in astrobiology and the scientific search for extraterrestrial intelligence, influencing how the scientific community approaches these questions.
