Scoop of American astronomers, made on the first day of autumn, go unnoticed, while at other times the event would focus on all the leading newspapers editorials planet. After all, it was about getting a radio signal from space that has, apparently, artificial.
It has been over three weeks, but during that time none of the reputable skeptics of the scientific community has not managed to convincingly refute the bold assumption that humans have finally received this message from the aliens. Authors sensations were American scientists from the National Astronomy and Ionospheric Center, University of California at Berkeley. September 1 in the pages of authoritative magazine New Scientist, they reported that they were able to fix the radio, which has an artificial origin. Signal, called SHGb02 +14 a, was found Arecibo radio telescope in Puerto Rico as part of an international program to search for extraterrestrial intelligence with distributed computing SETI @ home.
Signal to the laws of nature
March 18, 2003 in Berkeley, astronomers have put the antenna at Arecibo sky areas from which they were derived most suspicious signals. Could confirm only one — SHGb02 +14 a. A very weak signal was recorded three times. Its total length was one minute.
Of course, this is not enough for a complete analysis, but as carefully observed one of the project leaders, an astronomer at the University of Berkeley, Dr. Dan Vertimer, "SHGb02 +14 a — the most interesting signal in the history of the program SETI @ home. We do not jump to the ceiling with joy , but we continue to watch him. " His colleagues were not so restrained in expression, and in one voice declared the long-awaited message from aliens. It is fair to say that the reason for this, they were, and very serious.
Mysterious signal came from a point located somewhere between the constellations Pisces and Aries. Not a single star or a famous astronomer of the planetary system within one thousand light-years from Earth in the area do not. However, the head of the Russian Science and Culture Center SETI Leo Gindilis rightly observed for the "NO": "There is no indication that the source is so far away from Earth. It can be located either in interstellar space, and directly in the solar system, because which object emits radio waves, we do not know. "
Furthermore, the signal SHGb02 +14 a was caught on a frequency of 1420 MHz. It is at this frequency emits and absorbs energy neutral atomic hydrogen, the most abundant element in the universe. Back in the 60's of the last century, the founding fathers of SETI have suggested that aliens, if they wish to contact us, it will use this frequency. "The narrow range of radiation itself is alarming, because natural objects — pulsars, quasars, stars, interstellar gas, etc. — emit energy in all possible frequencies, — says the" discovery of the century "Leo Gindilis. — But more strangely different.
First SHGb02 +14 a was registered as a signal with a constant frequency, and then she began to change dramatically — from 8 to 37 hertz per second. If we assume that we are dealing with a natural object, it should rotate around its axis with a terrific speed — about 40 times faster than the Earth. Honestly, imagine what it could be, it's difficult. But everything falls into place, if we assume that the radio-emitting object has an artificial origin. "
According to our interlocutor, this modulation signal can be laid specifically to humans pay attention to it, because the natural astronomical objects emit either a constant or a variable rate. "Experts SETI long assumed that if the representatives of extraterrestrial civilizations will want to contact us, they will send a signal that contradicts the laws of nature a priori, — says Mr. Gindilis. — It is fair to say that once we have pierced.
As part of the program The Search for Extraterrestrial Intelligence is one of the leading experts SETI discovered object with red and violet spectral shift. All, apparently, has said that he has an artificial origin. Simply put, we detected an alien ship, which is closer to the Earth, giving the blue shift, then moved away from her, causing a red shift.
Subsequent studies, however, show that the mysterious object is just a star ejected from trui gas in opposite directions. "Withdrawal of Russian scientists agree colleagues from other departments of SETI. Example, American Eric Korpela said that" the signal, similar SHGb02 +14 a, can modulate any known astronomical objects. "
Natural phenomena or tricks hackers? Not possible, however, that we are dealing with an unknown natural phenomenon, the benefit such cases in the history of the hunt for extraterrestrial intelligence have already been. In 1967, astronomers have recorded a pulsating signal and hurried to write it off on the activity of aliens. However, it later became clear that the radio source is a pulsar — a rotating neutron star, will rend the powerful directional beams of radiation. "It is possible that at this time we will open an entirely new class of astronomical objects, but in any case it is a new word in science" — zayavill "NO" director Astro Space Center of Lebedev Physical Institute, RAS Nikolai Kardashev.
Other possible versions of the appearance of a mysterious radio signal is not so romantic. Chief astronomer Seth Shostak of the SETI Institute suggests that it can be generated by the telescope, Arecibo, which has a fixed dish-reflector diameter of 305 meters and scan the skies, changing the position of the receiver relative to the mirror. It is possible that in certain position terrestrial waves can be reflected in the dish and get back as a signal arriving from space. Check out this version is simple — listen to others SHGb02 +14 a
