The Search for Extraterrestrial Intelligence (SETI) is an ongoing scientific effort to detect signals from alien civilizations. SETI uses large radio telescopes to listen for unusual signals that could be evidence of intelligent life beyond Earth. The search focuses on detecting radio waves or other forms of communication that might be emitted by technologically advanced civilizations.
While no definitive signals have been detected, SETI continues to be a crucial part of the search for life beyond Earth. The discovery of even the smallest evidence of alien life would have profound implications for our understanding of the universe and our place in it.
