报告题目：Are We Alone? -Searching for ET

　　摘    要：SETI is an acronym for the Search for Extraterrestrial Intelligence. It is the science of using telescopes, radio and optical, to search the skies for signals from alien civilizations.

              The idea of SETI began in 1959 with the publication of a paper in the British journal Nature by Giuseppe Cocconi and Philip Morrison. The paper discussed the possibility of the existence of alien civilizations and how we might be able to detect them. Their conclusion was that the easiest method of detection would be radio waves.

          Radio waves were chosen because they are capable of traveling the vast distances between stars and can be generated with reasonable amounts of power. We have been sending radio waves out into space for more than sixty years. All of our radio, TV, satellite, and radar signals are currently spreading out throughout the galaxy. Perhaps they've already been detected by someone.
