The Arecibo radio telescope, the Puerto Rican observatory made even more famous for its part in the 1995 James Bond film Goldeneye, began receiving a mysterious signal May 12 during an observation of Ross 128, Business Insider Science reports. The so-called red dwarf star appeared to be the point of origin, but researchers are not betting that the signal was a result of intelligent life — though they aren’t ruling it out at this point.

The star does not appear to have any planets, and is around 2,800 times dimmer than the sun. At this point researchers are hypothesizing that the signal could be from a satellite or other human-made device. To date, scientist have not seen stars emit bursts of this kind.
