The Russian news outlet TASS reports on the analysis of HD 164595:
An unusual signal registered by the Ratan-600 radio telescope at the Zelenchukskaya observatory in the North Caucasus Republic of Karachay-Cherkessia is a terrestrial disturbance rather than a sound from an unearthly civilization, telescope researcher Yulia Sotnikova told TASS on Tuesday.
“Last and this year, the telescope’s work has focused on searching for sun-like stars,” Sotnikova said.
“There have been no scientific results within the framework of this research so far. Some time ago, in the spring of this year, an unusual signal was received but its analysis showed that it was most likely a terrestrial disturbance,” she noted, adding that the observatory was preparing the text of an official disclaimer to dismiss media reports on the discovery of a signal from an unearthly civilization.
Jacob Aron provides additional context in NewScientist (10 September 2016, paywall):
Although we can’t say for sure, it is almost certain that aliens have arisen from the primordial goo elsewhere. Even if the odds of life are incredibly low, a universe 93 billion light years wide provides ample rolls of the dice to get things started.
And yet, its vastness also prevents us from making contact. Seth Shostak at the SETI Institute in Mountain View, California, calculated that if the signal had been real, aliens at HD 164595 would have needed to consume an entire sun to provide enough energy for it to reach us, assuming they beamed it in all directions. If the message was specifically directed at us, that energy requirement drops to “only” the entire historical power consumption of humanity.
