Mysterious Radio Signal Could Be Aliens — or Just Noise
The empire needs to call back. Russian astronomers at an observatory in Zelenchukskaya picked up a mystery signal with their RATAN-600 radio telescope last year, and only recently let the SETI — Search for Extra Terrestrial Intelligence — community know about it. The signal was coming from the constellation Hercules, about 94 light years from us, near a sun-like star. While scientists are recommending monitoring in case it was from an alien civilization, they also caution it might just be a quasar or other space static.
