Astronomers Receive Radio Signal That Is a "Good Candidate" for Extraterrestrial Intelligence
Have we just made contact with extraterrestrial life? (Or, more accurately, has extraterrestrial life just made contact with us?) An international team of astronomers has just detected signals coming from almost 100 light years away, and they believe the signal is a strong candidate for extraterrestrial contact.

The team of researchers reported in a document circulated by contact person Alexander Panov (via Centauri Dreams) that they detected "a strong signal in the direction of HD164595," a planet system in the constellation Hercules. The signal was detected on May 15, using the RATAN-600 radio telescope in the Russian Republic of Karachay-Cherkessia.

The researchers have not reached a conclusion as to the cause of the signals, but they cannot rule an extraterrestrial civilization out. In fact, they claimed in a presentation that it was a very strong candidate for extraterrestrial intelligence, although further study would be needed in order to rule out other causes.

Opening quote
The estimated probability ~2 X 10-4 to simulate the signal from the direction of the HD164595 by signal-like noise is small, therefore HD164595 is good candidate SETI. Permanent monitoring of this target is needed.

And if it did come from aliens, then based on the strength of the signal and the distance it traveled, the researchers calculated that the signals would be the work of extremely advanced civilizations. If it were an isotropic beacon of radio signals, meaning one that extends in all directions, then it would be the work of a Type II civilization on the Kardashev scale, which would make it approximately a few thousand years ahead of human civilization. If it were a targeted beacon aimed directly at our planet, it would be the work of a Type III civilization, which is estimated to be 100,000-1 million years ahead of humanity and can perform such feats as harnessing the energy of supermassive black holes.

There are several other possible sources that need to be investigated; the researchers admit that it's a possibility, for example, that the signals are simply background noise that has been enhanced by gravitational microlensing. But still, there is a chance that these signals are from an alien species, and if they are, it would be one of the greatest scientific discoveries in history.
