The Wow! signal represented as "6EQUJ5". The original printout with Ehman's handwritten exclamation is preserved by Ohio History Connection. [1]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.
The Wow! signal represented as "6EQUJ5" on the original computer printout. In 1977, the Big Ear recorded an unusual and possible extraterrestrial radio signal, which became known as the Wow! signal. The observation would prove to be unique, since no similar signals were ever detected afterwards. [3]
The search for extraterrestrial intelligence (SETI) is a collective term for scientific searches for intelligent extraterrestrial life.Methods include monitoring electromagnetic radiation for signs of transmissions from civilizations on other planets, [1] [2] [3] optical observation, and the search for physical artifacts.
The signal appears to have originated from the direction of Proxima Centauri. It has been given the name Breakthrough Listen Candidate 1 . As of December 2020, the researchers were still working to rule out terrestrial interference, which they considered the most likely cause. One researcher called it "on par" with the Wow! signal.
In 1967, a radio signal was detected using the Interplanetary Scintillation Array of the Mullard Radio Astronomy Observatory in Cambridge, UK, by Jocelyn Bell Burnell. The signal had a 1.337 302 088 331-second period (not in 1967, but in 1991) and 0.04-second pulsewidth. [4] It originated at celestial coordinates 19 h 19 m right ascension, +21 ...
On 13 February 2015, scientists (including Geoffrey Marcy, Seth Shostak, Frank Drake, David Grinspoon and David Brin) at a convention of the American Association for the Advancement of Science, discussed Active SETI and whether transmitting a message to possible intelligent extraterrestrials in the Cosmos was a good idea; [3] [4] one result was ...
