Signal from space (1977). Strange signals from outer space

Since the 60s of the last century, scientists from all over the world have been 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 recorded in the universe. This was made possible thanks to a specially designed 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.

The very first signal

In mid-August 1977, a truly incredible event happened. Dr. Jerry Eyman of Ohio State University, who was working on the SETI program on a radio telescope called the Big Ear, received a signal from space. It turned out to be quite strong and long, all its parameters indicated that it was of artificial origin. Shocked by what he saw sensational data, the American exclaimed: “Wow! Signal» Preciselyso they began to call the caught signal from space in the future.

It's been more than 35 years, and his secret, unfortunately, has not yet been revealed. Scientists have not given any intelligible explanation for its occurrence. Astronomers have no assumptions about the natural nature of the source of this signal. Therefore, there are enough people who are inclined to believe that he was sent from an alien ship.

This version is also supported by the fact that the signal from outer space (1977) came from the area where the constellation Sagittarius is located, but from an empty part of the sky. It should be noted that after so many years no other explanations have followed.

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 on it 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 Big Ear antenna is stationary 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, for 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's version

It must be said that the use of the social network Twitter to compose a message to alien "brothers in mind" looks symbolic against the backdrop of innovative ideas expressed by scientists participating in the SETI project. Gregory and James Benford, researchers at the University of California, believe there is a similar Twitter on other planets.

The current principle of searching for other civilizations is based on the fact that the "brothers" also continuously send signals into space. But to send them far enough would require a colossal expenditure of energy, which is an unforgivable waste. Therefore, the Benfords 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 simply could have missed a large number of such signals or caught them purely by chance, as happened with “Wow! Signal".

Caution

It is worth noting that not all scientists enthusiastically perceive the attempts of their colleagues to contact alien civilizations. For example, Stephen Hawking - a famous British astrophysicist - is very disapproving of this idea. In his opinion, humanity needs to sit quietly and not attract too much attention from aliens. He believes that the appearance of "brothers in mind" will be similar to the stay of Christopher Columbus on the American continent. And, as you know, for the Indians it ended very badly.

Stephen Hawking believes thatalien races can live aboard huge ships, as they have already exhausted the natural resources of their planets. Therefore, they may have a desire to rob the Earth. It is believed that aliens are now at a higher level of development than humanity, and they have the ability to roam the universe in order to capture some suitable planet for them.

2010 Signal

In early September 1977, a spacecraft called Voyager 1 launched from the United States (Cape Canaveral). A little later, another one followed him - his twin brother. The program, of which these vehicles were a part, was designed to explore giant planets that are far from the Earth. According to the plan, the first of them was supposed 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 Voyagers was placed a message for aliens, recorded on a gold record. It contained a greeting in different languages, children's laughter and crying, various sounds of nature, etc. All this was intended to help our alien "brothers" understand what our Earth is like.

For more than 30 years, spacecraft have been flying in the universe and have transmitted nothing but the beating of their own electronic heart. But at the end of April 2010, a grand event occurred - Voyager 2 sent a signal from space, which it managed to receive itself. He followed from that partA universe about which the inhabitants of our planet know nothing yet.

Reporting this was a real sensation. Because of this, scientists are divided into two camps. Some are sure that this signal is a manifestation of hitherto unknown laws of the cosmos, while others consider it a response from "brothers in mind".

Now the mission of the Voyagers has already been completed, and they have gone beyond the solar system. NASA employees tend to explain strange signals from space by the fact that their spacecraft have expired and are simply out of order. In addition, they flew into such a distant space, where other laws of physics may operate, completely unknown to our scientists.

New signal

NASA experts together with the European Space Research Agency in the middle of last year made another sensational statement. They reported that they had caught a signal from space, which came 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.

According to scientists, the signal is an intense pulse, which is in the wavelength range of X-rays. Its source has not yet been established, but it has been suggested that it may come from some "sterile neutrinos" that are the foundation for the emergence of the so-called dark matter. According to a theory popular in scientific circles, it occupies approximately 85% of the entire universe, although it has not yet been scientifically proven.the fact of its existence. NASA assured that the mysterious signal from space in 2014 will still be studied in order to establish its source.
