The primary way that astronomers carry out SETI programs is by using radio telescopes to search for signals from extraterrestrial civilizations. This method is known as the Search for Extraterrestrial Intelligence (SETI) and has been ongoing for many decades. Other methods, such as analyzing high-resolution images of nearby stars or analyzing the spectra of extra-solar planets, may be used in conjunction with radio telescope observations, but radio telescope searches remain the primary approach.
