A few days ago, astronomers announced that the solar system in the neighborhood along the red dwarf of our galaxy more than any other Star Clusters may be abundant in the Earth like exoplanet. But how many of them could be home to reason, the capability of life? Recent studies show that such planetary systems can be almost 1 out of 100. In other words, almost every hundred Earth-like planet can thrive civilization of intelligent beings.
Moreover, they should be technologically advanced as to be able to space to broadcast radio signals, it is possible to accept and what has not for decades thi ioe in space looking for extraterrestrial mind searches SETI Institute. thi ioe
One out of a hundred, it seems, thi ioe is not much. But remember, as far as the stars in the Milky Way, it would follow that there should exist more than 1 million. stars, around which revolve the distant worlds of our mind brothers. Those civilizations thi ioe would be possible to communicate by radio. More than a million of the civilized world - and this is just one of the galaxy!
Group SETI Institute researchers celebrated Jill Tarter (Jill Tarter) in front of the University of California, Berkeley, researchers in West Virginia built radio telescope in Green Bank Telescope thi ioe tried to catch intelligences transmitted radio signals. Telescope antenna was directed to the 86 stars of the planets that have been discovered in space observatory, Kepler mission.
Radio observations of these worlds have been chosen because they are around their mother star orbits being called the "life zone". In addition, in all of the planetary systems thi ioe planetary star had at least 5 or between them had to be quite prolonged orbits borne super-Earth-like planet.
"Mind the brothers still have not found, but for the first time in the history of research, we were able to draw a fairly tangible boundaries, indicating how many intelligent civilizations might be capable to send radio waves," - commented on the results of the University of California, Berkeley, astronomer Andrew Siemionas (Andrew Siemion).
Investigators searched radio 1-2 GHz range - precisely the frequency here on Earth, spreading mobile telephony and TV broadcast waves. Scientists are trying to catch up to 5 Hz amplitude of radio signals, because in nature there are no natural sources, emitting only a few hertz amplitude signals.
"No more than 5 Hz issue of our selected range, as far as we know, is a guaranteed indicator which points to such a signal sends protaujanti civilization" - reads the results of presenting article.
Telescope radio signals Incorporated 12 hours - after 5 minutes. each selected star. Most of them are from the distant land of 1 thousand. and more light-years thi ioe away, so it was possible to detect only those signals that are sent to targeted toward the solar system. The researchers say that the future is much more sensitive radio telescopes (eg., SKA) will be able to catch the much weaker radio signals - even those who have been in space ištransliuoti randomly (like eg., In the case of human targets without any space emanates TV and radio waves: the first wave of radio broadcasting space managed to go after more than 100 light-years).
A group of researchers telescope in Green Bank Telescope plans to conduct more studies, in which more attention will be paid to daugiaplanetėms systems, thi ioe in which the Earth-like thi ioe planets are at least two. The hope is that such cases succeed in capturing between these planets ongoing communication.
