SETI Is Investigating a Possible Extraterrestrial Signal

-

The unusual signal was originally detected on May 15, 2015 by the Russian Academy of Science but was kept secret from the international community. Now, SETI is investigating this possible Extraterrestrial Signal from deep space.

SETI researchers are buzzing about a strong spike in radio signals that seemed to come from the direction of a sunlike star in the constellation Hercules, known as HD 164595. The signal conceivably fits the profile for an intentional transmission from an extraterrestrial source.

The mysterious star’s designation is HD164595 and it’s considered to be sun-like in nature with a nearly identical metallic composition to our own star. So far, a single Neptune-like (but warmer) planet has been discovered in its orbit–HD 164595 b. But as Paul Gilster explained, “there could, of course, be other planets still undetected in this system.”

The signal’s strength indicates that if it in-fact came from a isotropic beacon, the power source would have to be built by a Kardashev Type II civilization. The Kardashev scale is used to determine the progress of a civilization’s technological development by measuring how much energy was used to transmit an interstellar message.  An ‘Isotropic’ beacon means a communication source emitting a signal with equal power in all directions while promoting signal strength throughout travel.

Basically, if the signal was beamed out into the galaxy without aim or direction, that would require an enormous amount of power to actually be detected. But what if the signal was beamed specifically at our solar system? Well, that would require less energy and could indicate the presence of a Kardashev Type I civilization–meaning that it could be a highly-technological, contemporary society. This particular civilization’s social structure is theorized to be completely globalized and interconnected.
