Since the 60s of the last century, scientists fromall over the world are listening to signals that come from space in order to catch at least some message from an extraterrestrial civilization. Now there are about 5 million volunteers participating in the Seti @ home project and trying to decipher the billions of radio frequencies that are constantly being recorded in the universe. This became possible thanks to a specially developed program that is installed on home computers. All information collected from the most powerful radio telescopes is sent via the Internet directly to the processors.
Very first signal
В середине августа 1977 года случилось поистине incredible event. Dr. Jerry Eiman of Ohio State University, who was working on the SETI program on a radio telescope called “Big Ear,” received a signal from space. He turned out to be quite strong and long, all his parameters indicated that he was of artificial origin. Shocked by the sensational data he saw, the American exclaimed: “Wow! Signal "This is how they began to call the captured signal from space.
It's been over 35 years, and his secret, toUnfortunately, still not disclosed. His appearance, scientists have not given any intelligible explanation. Astronomers have no assumptions about the naturalness of the source of this signal. Therefore, there are enough people who are inclined to believe that he was sent from an alien ship.
In favor of this version speaks the fact thatthe signal from space (1977) came from the area where the constellation Sagittarius is located, but from the empty part of the sky. It should be noted that no other explanations followed after so many years.
Description “Wow! Signal
The strength of this signal exceeded the background by 30 times.Its frequency was 1.42 GHz, which corresponds to hydrogen. It was there that scientists waited and are still waiting for at least some messages from extraterrestrial civilizations. This signal lasted 72 seconds - it should have had the same amplitude if it had an artificial origin. The fact is that the antenna of the “Big Ear” is fixed and uses the rotation of our planet to scan the sky. Therefore, a possible signal source can only be heard for 72 seconds. Of these, almost half the time it gradually increases, and in the meantime the telescope aims at the source. Then the remaining 36 seconds, the signal from space gradually decreases. This is exactly what was recorded by the Big Ear radio telescope.
Benford version
I must say that the use of the social networkTwitter in order to compose a message to the alien “brothers in mind” looks symbolic against the background of innovative ideas expressed by scientists participating in the SETI project. Gregory and James Benford - researchers from the University of California - believe that there is a similar Twitter on other planets.
The principle of the search for othercivilizations based on the fact that the "brothers" also continuously send signals to space. But in order to send them far enough, they would require huge amounts of energy, which is an unforgivable waste. Therefore, Benford's believe that aliens can send their signal from space in the form of a short message, similar to the one that people leave on Twitter. According to these scientists, humanity could simply miss a large number of such signals or catch them purely by chance, as happened with “Wow! Signal.
Warning
It is worth noting that not all scientists are enthusiasticperceive the attempts of their colleagues to connect with alien civilizations. For example, Stephen Hawking - the famous British astrophysicist - is very disapproving of this idea. According to him, humanity needs to sit quietly and not attract too much attention from the aliens. He believes that the appearance of "brothers in mind" will be similar to the stay of Christopher Columbus in the Americas. And, as you know, for the Indians it ended very badly.
Stephen Hawking believes that alien racescan live on the boards of huge ships, since they have already exhausted the natural resources of their planets. Therefore, they may want to rob the Earth. It is believed that aliens are now at a higher level of development than humanity, and they have the opportunity to wander in the Universe in order to capture some suitable planet for them.
2010 signal
In early September 1977 from the United States (CapeCanaveral) launched a spacecraft called "Voyager 1". A little later, another one followed him - his twin brother. The program, of which these devices were part, was designed to explore giant planets that are far from Earth. According to the plan, the first of them was to visit Saturn and Jupiter, and the second - Neptune and Uranus. In addition, with the help of devices it was supposed to study the satellites of the planets, their physical characteristics, as well as take pictures at close range.
On board both of the Voyagers there was a message.for aliens recorded on a gold plate. It contained greetings in various languages, children's laughter and crying, various sounds of nature, etc. All this was intended to help our alien "brothers" to understand what our Earth is.
Более 30 лет космические аппараты летали во Universe and nothing but the sound of their own electronic heart, did not transmit. But at the end of April 2010, a grand event happened - Voyager-2 sent a signal from space, which he was able to receive himself. It followed from that part of the Universe, about which still nothing is known to the inhabitants of our planet.
Сообщение об этом стало настоящей сенсацией.Because of this, scientists are divided into two camps. Some believe that this signal is a manifestation of hitherto unknown laws of the cosmos, while others consider it a response from the "brothers in mind."
Now the mission of the Voyagers has already been completed, and theywent beyond the solar system. NASA staff tend to explain strange signals from space by the fact that their spacecraft life has ended, and they simply went out of order. In addition, they flew into such a distant space, where other laws of physics, completely unknown to our scientists, can operate.
New signal
NASA Experts with the European AgencySpace Exploration in the middle of last year made another sensational statement. They reported that they had caught a signal from space, which had arrived from the area where the constellation Perseus is located. I must say that the distance between these celestial objects and our planet is about 240 million light years.
По словам ученых, сигнал представляет собой intense pulse, which is in the wavelength range of x-rays. The source has not yet been able to establish it, but it has been suggested that it may come from some "sterile neutrinos" that are the foundation for the emergence of so-called dark matter. According to the theory popular in scientific circles, it occupies approximately 85% of the entire Universe, although the fact of its existence has not yet been scientifically proven. NASA assured that the mysterious signal from space in 2014 will still be studied in order to establish its source.
