Radio astronomer Frank Drake used an 85-foot dish at the National Radio Astronomy Observatory to listen near 1420 MHz for signals from Tau Ceti and Epsilon Eridani from April to July 1960. Nothing artificial was found; it began scientific SETI.
Ten scientists, including Frank Drake, Carl Sagan and Philip Morrison, met at the Green Bank radio observatory for the National Academy of Sciences' Space Science Board. Drake's equation, used to frame the talks, became the standard way to estimate how many civilizations might exist.
The Breakthrough Listen project pointed West Virginia's Green Bank Telescope at 'Oumuamua, the first known interstellar object, across four radio bands. Its initial results found no sign of artificial signals, though most of the data was still being analyzed.
