Anyone there? The SETI detects a strange signal from a distant star
If astronomers and scientists do not have enough to try to solve mysteries like the object in the solar system that does not orbit as it should or the famous ‘mega – structure’ of the star KIC 8462852, one of the radio telescope SETI has captured a ” powerful ‘ and no less mysterious signal in space.
As told in the specialized blog Centauri Dreams, an international team of astronomers led by Italian Claudio Maccone has published the first preliminary data on the signal, which comes from a star 95 light years away and was detected on 25 May 2015 by Russian RATAN-600 radio telescope. Its power is atypical, although it is still too early to start talking about extraterrestrial civilizations.
The signal is relatively powerful with a wavelength of 2.7 cm and an estimated amplitude mJy 750. Seems to come from HD 164595, a star of 0.99 solar masses with an estimated age of 6,300 million years old and located 95 light years from Earth. In its orbit has been detected at least one planet, although still not known if it is the only one who has named HD 164595 b, a similar size to Neptune orbits that last only 40 days.
The discovery leaves open to all sorts of hypotheses doors, and Centauri Dreams and speculate that the signal strength could point to a civilization of Type II in the Kardashev scale, corresponding to those which would be able to use all the available power of a single star. According to this scale, humanity still has between 100 and 200 years to reach Type I, which is the lowest of the three that compose it.
But we should not get overly excited with this idea. Nick Suntzeff astronomer, University of Texas A & M, has told Ars Technica that has been observed in a part of the radio spectrum used by the military, so they could have a domestic origin.Of course, he also said that if he had a truly astronomical source would certainly be something really strange.
Anyway, the signal pool creates enough doubt as to researchers radiotelescope RATAN-600 Zelenchukskaya, Russia, they have requested permission to monitor on an ongoing basis its origin. The committee SETI meanwhile discuss the signal next September 27 in Mexico during the 67th International Astronautical Congress to be held in Guadalajara.
It will be after that meeting when we begin to have more data on the discovery and initial findings of those who have spent decades exploring space for any kind of signal that points to the presence of life or extraterrestrial intelligence. Still, until not continue investigating the signal and its origin cannot be reached any solid conclusions.
