Scientists say “Intelligent Alien life cannot be ruled out,” and that “and observations of other stars immediately before and after did not show anything similar.” Furthermore, the signals are “not local radio frequency interferences and are unique to Ross 128.”
Astronomers searching the universe for habitable worlds and Extraterrestrial life have intercepted “strange signals” coming from a solar system located ‘just’ 11 light-years away from Earth.
Scientists from the Arecibo observatory—a 305-metre radio telescope in Puerto Rico—say the signals are coming from Ross 128—a red dwarf star that according to reports is not known for having any planets orbiting it. The red dwarf is around 2,800 times dimmer than the sun.
Based upon parallax measurements, the distance of this star from Earth is 10.89 light-years (3.34 parsecs), making it the twelfth closest star to our Solar System.
According to Prof. Abel Mendez, an Astrobiologist from the University of Puerto Rico at Arecibo, the enigmatic star was observed for around 10 minutes during which the ‘strange signals’ were picked up and observed to be “almost periodic”.
“Two weeks after these observations, we realized that there were some very peculiar signals in the 10-minute dynamic spectrum that we obtained from Ross 128 (GJ 447), observed May 12 at 8:53 PM AST (2017/05/13 00:53:55 UTC). The signals consisted of broadband quasi-periodic non-polarized pulses with very strong dispersion-like features. We believe that the signals are not local radio frequency interferences (RFI) since they are unique to Ross 128 and observations of other stars immediately before and after did not show anything similar,” wrote Professor Mendez in a post.
Speaking about the enigmatic signals, Mendez said that while it’s extremely unlikely that we’ve actually intercepted signals from Aliens, the possibility cannot be ruled out yet.
“In case you are wondering, the recurrent Aliens hypothesis is at the bottom of many other better explanations,” wrote Méndez.
Among the many explanations Mendez mentions as the possible source of the signals, the astrobiologist says that it could be from something that humans put into space, like a satellite passing thousands of miles above Earth while the Arecibo Observatory was exploring, passing above Earth at great speeds.
“The field of view of [Arecibo] is wide enough, so there is the possibility that the signals were caused not by the star but another object in the line of sight,” Méndez said in an interview with Business Insider, adding that “some communication satellites transmit in the frequencies we observed.”
“We have never seen satellites emit bursts like that, which were common in our other star observations,” Mendez said of this theory.
However, it is noteworthy to mention that in a blog post written by Mendez, the astrobiologist wrote “we have never seen satellites emit bursts like that” and called the signals “very peculiar”.
The Arecibo Observatory is well-known for hunting for alien life in the universe, but among its many uses, experts also look at distant galaxies and help pinpoint near Earth asteroids.
“We will also observe Barnard’s star that day to collaborate with the Red Dots project. Results from our observations will be presented later that week,” wrote Mendez adding that he “has a piña colada ready to celebrate if the signals result to be astronomical in nature.”
