The Search for Extraterrestrial Intelligence (SETI) is a scientific effort aimed at detecting signs of intelligent life beyond Earth. Researchers use various methods, including radio telescopes, to listen for signals that may indicate the presence of advanced civilizations in the universe. The goal is to find evidence of communication or technology that could suggest life exists elsewhere. SETI projects often analyze data from space and monitor specific frequencies where extraterrestrial signals might be transmitted. The initiative is based on the assumption that if intelligent life exists, it may be trying to reach out, and scientists are eager to discover whether we are alone in the cosmos.
