Astronomers Have Detected 'Strange Signals' That May Come From A Star 11 Light-years Away

To see if the signals are still there, Méndez said Arecibo is going to stare down Ross 128 and its surroundings many more times, starting July 16.

"Success will be to find the signal again" at the star's location but not in surrounding directions, he said. "If we don't get the signal again then the mystery deepens."

Méndez wrote in his blog post that other radio telescopes might not be sensitive enough to pick up the signals, noting one exception: China's monstrous Five-hundred-meter Aperture Spherical radio Telescope, or FAST.

But FAST isn't operational right now, since it's being calibrated, and Méndez said he doesn't know when it will be back online.

Seth Shostak, a senior astronomer at the SETI Institute, confirmed that the group is "well aware of the signals" and might use its powerful Allen Telescope Array in California "to check them out."

"The chances are high that they're terrestrial interference, in fact. That's really always been the case," Shostak told Business Insider in an email.

Right now there's really only one compelling signal from outer space that might come from aliens: "[T]he WOW signal," Shostak said. "That one is still quite odd."
