![]() To this day, we still don’t know where it came from. "But after a while I started thinking, this is exactly the kind of signal we're looking for. In 1977 we received a radio signal from space that lasted 72 seconds. The telescope was scanning the stars searching for possible signals from alien civilizations as. Theories were flying everywhere then as scientists tried to unravel the sound’s sweet mystery. "My first thought was that it must be interference," he told Nature. On August 15th 1977, a radio telescope located at Ohio State University detected something strange. Smith, who was working as a research intern with Breakthrough Listen, told his supervisor, University of California, Berkeley, astronomer Danny Price, who posted it to the Breakthrough Listen Slack channel. That's when Shane Smith, an undergraduate at Hillsdale College in Michigan, discovered the signal while sifting through data collected from Parkes. 15, 1977, when it was picked up by the Big Ear radio telescope at The Ohio State University. There is a humming sound that up to 11 of people can hear around the planet that drives some of them to suicide. The radio signal appeared on the night of Aug. But it went unnoticed until the following year. On Augwe received a 72 second radio signal from outer space and still don’t know where it came from. The 2019 signal was detected by the radio telescope as it spent 26 hours listening in the region of Proxima Centauri. "We've had false alarms in the past, and you get all excited only to be disappointed a couple of days later when you finally figure out that the signal was due to Homo sapiens, not the Klingons," Shostak says. Seth Shostak, a senior astronomer at the SETI Institute, tells NPR that he's ever hopeful of someday detecting an alien civilization, but his enthusiasm has been "tempered with time by realism."
