interstellar space reporter paul it remains only the barest of probabilities that astronomers have just found evidence of extraterrestrial , intelligent life . the unusual signal was originally detected on may 15 , 2015 , by the russian academy of science - operated ratan-600 radio telescope in zelenchukskaya , russia , but was kept secret from the international community . nevertheless , in the community of astronomers and other scientists who use radio telescopes to search the heavens for beacons of life there is considerable excitement about a new signal observed by a facility in russia . in may 2015 , researchers using a radio telescope in russia detected a candidate seti ( search for extraterrestrial intelligence ) signal that seems to originate from hd 164595 , a star system that lies about an international team of scientists from the search for extraterrestrial intelligence ( seti ) is investigating mysterious signal spikes emitting from a 6.3 - billion - year - old star in the constellation hercules—95 light years away from earth . the ratan-600 radio telescope , credit : nat-geo.ru hd 164595 , a solar system a few billion years older than the sun but centered on a star of comparable size and brightness , is the purported source of a signal found with the ratan-600 radio telescope in zelenchukskaya , at the northern foot of the caucasus mountains . the signal has been spotted coming from the star hd 164595 . the detection was made with the ratan-600 radio telescope in zelenchukskaya , in the karachay – cherkess republic of russia , not far from the border with georgia in the caucasus . although so far they have all come back empty - handed , two observatories will follow up on the tantalising signal again tonight . recent news of a spike in radio signals that could fit the profile for an intelligent , extraterrestrial source has seti astronomers across the globe swinging their radio dishes in hopes of confirming the detection .
