A Russian radio telescope detected a strong signal from a nearby star, which experts believe could be from aliens trying to contact us. If this turns out to be true, they could be located in HD164595b, a planet with a star called HD164595 in the constellation Hercules, about 95 light years away.
According to Search for Extraterrestrial Intelligence Institute’s Seth Shostak , the alien signal from the radio telescope RATAN-600 was detected on May 15, 2015 but he only heard about it now. The signal had a wavelength of 2.7 centimeters and an amplitude of 750 millijansky or mJy.
Experts explain that HD164595b has the same size as Neptune. It orbits HD164595 every 40 days. The star is 99 percent the size of the sun and is believed to be 6.3 billion years old.
Although Russian scientists have not yet commented on this topic, other experts suggest that the alien signal could have come from a radio beacon built by a type I extraterrestrial civilization from this planet. According to the Kardashev scale developed in the 1960s by the Russian astrophysicist Nikolai Kardashev, a type I civilization is a civilization with similar technology like ours.
However, there have been no signals that followed the first one so experts assert that they cannot conclude that the signal came from an extraterrestrial civilization yet. Still, they agree that the signal is interesting. Further observations are needed to understand it more.
On the other hand, some doubt that the signal came from an extraterrestrial civilization. Science and science fiction writer Paul Gilster says that the signal could have merely been caused by massive cosmic objects.
Glister likens it to the famous WOW! signal detected in August 15, 1977. The signal was also theorized to have been created by aliens but scientists figured this is unlikely since the signal was never detected again.
