Since the 60s of the last century, scientists from around the world are listening to the signals that come from outer space to catch at least some message from an extraterrestrial civilization.Now there are about five million volunteers involved in the project Seti @ home and trying to decipher the billions of radio frequencies permanently fixed in the universe.This was made possible thanks to a specially designed program that is installed on home computers.All collected with powerful radio telescopes information comes through the Internet directly to the handler.
The first signal
In mid-August 1977 is truly an incredible event happened.Dr. Jerry Eymanom of Ohio State University, who worked on the program SETI radio telescope called the "Big Ear" signal was received from space.He was quite strong and long, his options were talking about the fact that he has an artificial origin.Shocked pinned down sensational data, the American said: «Wow!Signal »is exactly what started later called catch the signal from space.
has been more than 35 years, and its mystery, unfortunately, has not yet been disclosed.His emergence, scientists did not however give any reasonable explanation.Astronomers have no assumptions about the natural source of the signal.Therefore, lack of people who are inclined to believe that he was sent to an alien spaceship.
in favor of this version is the fact that a signal from outer space (1977) came from the area where the constellation Sagittarius, but with a blank part of the sky.It should be noted that other explanations after so many years and has not followed.
Description «Wow!Signal »
The strength of this signal exceeded 30 times background.Its frequency was 1.42 GHz, which corresponds to hydrogen.It is waiting for its researchers, and are still waiting though any messages from extraterrestrial civilizations.This signal lasted 72 seconds - the same amplitude he should have, would have had if an artificial origin.The fact that the antenna "Big Ear" is fixed and uses the rotation of our planet to scan the horizon.Therefore, a possible source of the signal can only listen to 72 seconds.Of these, nearly half the time, he gradually increases, and in the meantime a telescope aimed at the source.Then, the remaining 36 seconds of the signal from space gradually decreases.That is what was recorded radio telescope "Big Ear".
version Benford
I must say that the use of the social network Twitter to compile messages extraterrestrial "brothers on reason" looks at the symbolic background of innovative ideas that expressed the scientists involved in the project SETI.Gregory and James Benford - Researchers from the University of California - believe that this Twitter is and on other planets.
exists in our time the principle of search of other civilizations is based on the fact that the "brothers" are also continuously send signals into space.But to send them far enough, it will require enormous expenditure of energy, which is an unforgivable extravagance.Therefore Benford believe that aliens may be a signal from outer space to send a short message like the one that people leave on Twitter.According to these scientists, mankind simply could miss a large number of such signals or catch them by accident, as happened with the «Wow!Signal ».
Caution
It should be noted that not all scientists are enthusiastically trying to perceive their colleagues to contact with alien civilizations.For example, Stephen Hawking - famous British astrophysicist - is highly disapprove of this idea.In his opinion, mankind needs to sit quietly and not attract too much attention from the aliens.He believes that the emergence of "brothers on reason" will be like a stay of Christopher Columbus in the Americas.As you know, for the Indians it ended very badly.
Stephen Hawking believes that alien races can live aboard the great ship, as has already exhausted the natural resources of their planet.Therefore, they may be tempted to plunder the Earth.It is believed that the aliens are now at a higher level of development than mankind, and they have the opportunity to roam the universe in order to capture some of the planet suitable for them.
signal 2010
At the beginning of September 1977 with the USA (Cape Canaveral) launched a spacecraft named "Voyager 1".A little later, after it went to another - his twin brother.The program, part of which is the data sets, was designed to explore the giant planets that are far away from the Earth.According to plan, the first of which was to visit Saturn and Jupiter, and the second - Neptune and Uranus.In addition, with the help of devices intended to explore the planet satellites, their physical characteristics, as well as take pictures at close range.
on board both "Voyager" was placed a message for extraterrestrials recorded on a gold plate.It contained greetings in different languages, children's laughter and weeping, various sounds of nature, and so on.. All this was intended to help the alien to our "brothers" to understand what constitutes our Earth.
over 30 years, the spacecraft flew into the universe, and nothing but knock own electronic heart, did not pass.But at the end of April 2010 there was a grand event - "Voyager 2" sent a signal from outer space, who managed to take himself.He followed from that part of the universe, about which nothing is known to the inhabitants of our planet.
Post this became a real sensation.Because of this, scientists have divided into two camps.Some believe that this signal - a manifestation of hitherto unknown laws of the cosmos, while others consider it a response from the "brothers on reason."Now
mission "Voyager" has already been completed, and they went beyond the solar system.NASA employees tend to explain the strange signals from space so that their spacecraft ended lifespan, and they are simply out of order.In addition, they have flown in space so remote that can operate other laws of physics, completely unknown to our scholars.
new signal
NASA experts, together with the European Agency for Space Research in the middle of last year, made another sensational statement.They reported that they caught a signal from outer space, who came from the area where the constellation Perseus.It should be noted that the distance between celestial objects and our planet is about 240 million light years.
According to scientists, the signal is an intensive pulse which is in the wavelength range of X-rays.Source it has not yet been set, but it was suggested that he might have come from some "sterile neutrinos" that are the foundation for the emergence of so-called dark matter.According to a popular theory in scientific circles, it takes about 85% of the entire universe, although research has not yet proven fact of its existence.In NASA assured that mysterious signal from outer space in 2014 will still be studied in order to determine its source.
