While you were out: 6EQUJ5 called
Radio astronomers at Ohio State University observe a signal from the direction of the constellation Sagittarius that seems to jump out from the usual cosmic background noise. The 72-second signal is quickly dubbed the “Wow Signal” (thanks to a hastily scribbled note), and is considered by some to be a strong candidate for a message from an extraterrestrial civilization since its frequency falls almost exactly on the hydrogen line of the electromagnetic spectrum, a wavelength closely watched by the SETI program. But more powerful telescopes listening in on the same region of space in the years and decades to come pick up no further signals. Scientists involved in the initial analysis later admit that the “message” may be of Earthly origin, reflected back from an object in space.
