Comet Likely Didn’t Cause Bizarre ‘Wow!’ Signal (But Aliens Might Have)
An astronomer thinks he’s pinpointed the source of a mysterious radio signal from space: a passing comet that nobody knew about. But his colleagues said they’re still skeptical of the explanation, noting that comets don’t emit radio waves in the right way.
Others aren’t so sure. “We do not believe the two-comets theory can explain the Wow! signal,” Jerry Ehman, the astronomer who discovered the Wow! signal in 1977, told Live Science.
The signal did not repeat, and subsequent attempts to find it proved fruitless. Ehman marked “Wow!” in red pen on a printout that shows the numbers representing the signal.
