Search for Extraterrestrial Intelligence, or SETI, is a scientific effort aimed at discovering signs of intelligent life beyond Earth. Researchers use various methods, including radio telescopes, to listen for signals from distant civilizations, hoping to find evidence of their existence. The search encompasses a wide range of activities, from analyzing data collected from space missions to monitoring specific star systems. SETI not only explores the cosmos but also raises profound questions about our place in the universe and the potential for life elsewhere.
