https://www.sciencealert.com/famous-wow-signal-might-have-actually-been-a-natural-space-laserThat leaves us with trying to find a natural explanation for the signal, which is what Méndez and his team have been attempting. Specifically, they looked for brief emissions of narrowband radiowaves similar in frequency to the Wow! signal in archived data from the now-retired Arecibo Observatory's Radio Emissions from Red Dwarf Stars (REDS) project.
They found four records worthy of further investigation, spotted coming from the vicinity of a tiny red dwarf named Teegarden's Star just 12.5 light-years away. Though fainter than the Wow! signal, they were similar enough that they could provide clues about the famous signal's origin.
According to the team's analysis, the signals near Teegarden's Star are associated with interstellar clouds of cold hydrogen. This points to a potential mechanism for the Wow! signal: a powerful flare of radiation traveling through a cloud of cold hydrogen, stimulating the gas to produce a powerful pulse of radiation close to 1420 MHz.
