Narrow-frequency pulses are naturally emitted by stars called pulsars, but they. Many hypotheses have been advanced on the origin of the emission, including natural and human-made sources, but none of them adequately explain the signal.Īlthough the Wow! signal had no detectable modulation-a technique used to transmit information over radio waves-it remains the strongest candidate for an extraterrestrial radio transmission ever detected. The search for extraterrestrial intelligence ( SETI) is a collective term for scientific searches for intelligent extraterrestrial life, for example, monitoring electromagnetic radiation for signs of transmissions from civilizations on other planets. A new search for extraterrestrial life aims to find out by listening for radio pulses from the center of our galaxy. an Ohio radio telescope called the Big Ear recorded a single pulse of radiation that seemed to come from somewhere in the constellation of Sagittarius at the 1420 MHz hydrogen line, the vibration frequency of hydrogen, the most common molecule in the universe -exactly the signal ET-hunters had been instructed to look out for. The signal suggests that the Earth-size planet may. August 15, 1977: the night before Elvis Presley died, at 11:16 p.m. The famous Wow signal was detected by the Big Ear Radio Observatory at Ohio State University it was thirty. The entire signal sequence lasted for the full 72-second window during which Big Ear was able to observe it, but has not been detected since, despite several subsequent attempts by Ehman and others. Astronomers have detected a repeating radio signal from an exoplanet and the star that it orbits, both located 12 light-years away from Earth. One such signal in particular caught astronomers’ interest on August 15, 1977. He was so impressed by the result that he circled on the computer printout the reading of the signal’s intensity, “6EQUJ5”, and wrote the comment “Wow!” beside it, leading to the event’s widely used name. Image via Big Ear Radio Observatory/ North American AstroPhysical Observatory. Ehman discovered the anomaly a few days later while reviewing the recorded data. The famous Wow signal detected by the Big Ear radio telescope at Ohio State University on August 15, 1977. The signal appeared to come from the direction of the constellation Sagittarius and bore the expected hallmarks of extraterrestrial origin.Īstronomer Jerry R. From Wikipedia: The Wow! signal was a strong narrowband radio signal detected on August 15, 1977, by Ohio State University’s Big Ear radio telescope in the United States, then used to support the search for extraterrestrial intelligence. Over the weekend, interstellar expert Paul Gilster broke the news that a strong signal was detected by Russian radio astronomers from the region around the star HD.
