The Search for Extraterrestrial Intelligence (SETI) is a scientific endeavor aimed at detecting signs of intelligent life beyond Earth. This field of research combines various disciplines, including astronomy, biology, and engineering, to explore the possibility that intelligent civilizations exist elsewhere in the universe. SETI primarily employs radio telescopes and other observational tools to listen for signals that might indicate the presence of alien civilizations.
