Green Bank Observatory has been a leading radio astronomy facility since its founding in 1957. Discoveries made here include the radio source at the center of the Milky Way, interstellar molecules, and the first pulsar in a supernova remnant, which confirmed the origin of these objects. It was also the site of the first systematic search for evidence of extraterrestrial civilizations.
