Something that just might exist:alien signal from HD164595

...there is considerable excitement about a new signal observed by a facility in Russia.

According to Paul Glister, author of the Centauri Dreams website, the Italian astronomer Claudio Maccone and other astronomers affiliated with the search for extraterrestrial intelligence have detected "a strong signal in the direction of HD164595." HD 164595 is a star of 0.99 solar masses about 95 light years from Earth, with an estimated age of 6.3 billion years. The system is known to have at least one planet, HD 164595 b, which is similar in size to Neptune and orbits its star in 40 days. Other planets may exist in the system as well.
The observation was made with the RATAN-600 radio telescope in Zelenchukskaya, in southern Russia, Glister reports. He cautioned that the evidence is very preliminary:
Ars contacted Nick Suntzeff, a Texas A&M University astronomer, for insight into what this signal at 11Ghz might be if it were not of alien origin. "If this were a real astronomical source, it would be rather strange," Suntzeff told Ars. Although there are mysterious, high-energy astrophysical phenomenon called “fast radio bursts” that are seen at a few gigahertz, they last only 10 milliseconds or so (this event lasted longer). Unfortunately, he said, there is no information given about the strength of the signal as a function of frequency.
Suntzeff added that he would not be surprised if the signal was due to a terrestrial origin, because at 11Ghz it occurred in a part of the radio spectrum used by the military. "God knows who or what broadcasts at 11Ghz, and it would not be out of the question that some sort of bursting communication is done between ground stations and satellites," he said. "I would follow it if I were the astronomers, but I would also not hype the fact that it may be at SETI signal given the significant chance it could be something military."
So it is likely terrestrial military. But it is fun to imagine that it is not.
