The primary way astronomers carry out SETI programs is by using radio telescopes to search for signals from extraterrestrial civilizations. This method allows astronomers to detect any radio signals emitted from distant planets, which could be indicative of intelligent life. Other methods, such as analyzing high-resolution images or searching for planets with certain characteristics, can also be used as part of a SETI program but are not the primary method.
