SETI Investigating Signal From Sun-Like Star 95 Light-Years Away
Over the weekend, astronomers trained their telescopes a relatively close star, hoping for more evidence of a curious signal heard over a year ago by Russian radio telescope operators.
First detected on May 15, 2015—but only just now reported to other SETI scientists—the 11 GHz signal appears to have originated from HD 164595, a star with 0.99 solar masses and known to have at least one planet orbiting it, a so-called “warm Neptune.”
The Allen Telescope Array, one of the telescopes now observing HD 164595.
The frequency of the signal is unlikely to be an astrophysical phenomenon, though scientists have yet to rule out terrestrial interference.
Here’s Alan Boyle, reporting for GeekWire:
At least two SETI research groups are aiming to track HD 164595 tonight. The SETI Institute is using the Allen Telescope Array in northern California, while METI International is looking to the Boquete Optical SETI Observatory in Panama.
[Centuari Dreams’ author Paul] Gilster reports that the signal spike was detected more than a year ago, on May 15, 2015, by the RATAN-600 radio telescope in Zelenchukskaya. That facility is in the Russian republic of Karachay-Cherkessia, not far from the Georgian border.
Doug Vakoch, president of METI International, a SETI-affiliated group, expressed dismay in an email to Boyle that the report took so long to make its way to other scientists, saying that quick communication can help confirm the source or rule out interference. Vakoch’s team is among those now observing the star.
The high frequency is what’s driving interest in the signal. Here’s Eric Berger, reporting for Ars Technica:
“If this were a real astronomical source, it would be rather strange,” [astronomer Nick] 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.
It’s possible that an 11 GHz radio signal could be ground-to-satellite communication or some unknown military transmission.
For now, given the number of caveats attached to this signal, astronomers are downplaying the possibility of extraterrestrial life.
We are on the verge of answering one of the greatest questions in history: Are we alone?

Oh c'mon man.
11 GHz is where everyone in the commercial access point wifi point to point backhauls has been migrating towards.
The 5 GHz band has been saturated and is noisy as hell in most high use areas now a days.
11 GHz and 24 GHz is now becoming standard for backhauls .....

I heard from a buddy at Vandenberg that it was a retransmission relay of a Gilligan's Island episode replete with subtitles from some unknown language.

I don't think we are going to have to worry about clean air and water, for much longer.
Let's hope they land in Russia, first.

To start running up my credit card balance on hookers and blow?

May we assume you employ only 5.13 hookers?

Yeah Mike. Why aren't you around when we need you?

That's cuz they haven't caught up with the terrestrial yet.

"Working out the strength of the signal, the researchers say that if it came from an isotropic beacon, it would be of a power possible only for a Kardashev Type II civilisation.
If it were a narrow beam signal focused on our solar system, it would be of a power available to a Kardashev Type I civilisation.'
The Kardashev scale is a way of measuring an alien society's technological advancement based upon how much energy it has at its disposal.
A Type I civilisation is given to species who have been able to harness all the energy that is available from a nearby star, gathering and storing it to meet its population's demands.
A Type II civilisation is much more advanced and can harness the power of their entire star.
Type III is a species that has been able to master everything having to do with energy. Earth doesn't feature on the scale."

Just assume if there are hookers involved it's not free, just like climbing.
