Hmmm.

HMMMM.

HMMMM.

An Interesting SETI Candidate in Hercules

Data:

Star: HD164595. Near-clone of the sun, 0.99 solar masses, 91 lightyears away in the direction of Vega, one confirmed planet (a “Warm Neptune” 16 Earth masses, 40-day orbit).

Detection: RATAN-600 radio telescope in Zelenchukskaya, in the Karachay–Cherkess Republic of Russia, not far from the border with Georgia in the Caucasus.

Signal: wavelength of 2.7 cm, 750 mJy.

The signal was apparently *very* powerful. If it was a directional beam, this would mean (assuming it’s an intelligent signal) it was sent towards Earth around 1925; “they” would have been looking at Earth circa 1834. Which means “they” obviously would not have been picking up terrestrial radio signals. A sufficiently advanced astronomical culture might have been able to spot Earth telescopically, and *perhaps* took note of changes in Earths atmosphere going on at the time, indicators of an early fossil-fuel fueled industrial revolution.

The relevant paper is to be reported on at the 67th International Astronautical Congress in Guadalajara, Mexico, on Tuesday, September 27th, 2016.
