Project Ozma was an early attempt to detect possible signals from extraterrestrial civilizations using radio astronomy. Conducted in 1960, it is widely recognized as the first scientific search for intelligent life beyond Earth through radio signal monitoring. Though limited in scope and duration, the project marked the beginning of what later became the broader scientific field known as the Search for Extraterrestrial Intelligence (SETI).
