The study of the meteorite fragments "Chelyabinsk" can help to identify the mechanism by which billions of years ago, created the solar system. Such a possibility does not exclude the Ural scientists, among them — the doctor of physical and mathematical sciences, senior researcher at the department of physical methods and quality control devices UrFU Oshtrakh Michael, who told reporters in Yekaterinburg on the first results of the study of the heavenly guest at last Monday's press conference in agency " ITAR-TASS ".
Researchers UFU completed physical and chemical analysis of a meteorite that fell in the Chelyabinsk region, by comparing the chemical composition of the samples with 11 classes of meteorites like LL, L and H with the help of the so-called Mössbauer spectroscopy, which is now widely applied in the study of meteoric bodies, and in geology and metallurgy. It is likely that in the foreseeable future, fragments "Chelyabinsk" everyone will be able to see if the UFU implements its project to create in Ekaterinburg Museum of extraterrestrial matter. However, no unknown to science elements inside the wreckage, "Chelyabinsk" is not found, nor any trace of their "miraculous." Alien intelligence to their production did not put too tentacles.
According to Michael Oshtrakh, uniqueness "Chelyabinsk" is not in a special chemical structure, and that its fragments were discovered very quickly, so it does not have time to be exposed to the environment, particularly air and water oxidation. Thanks to this "Chelyabinsk" essentially free of iron oxides, but is rich in rock-forming silicates (olivine and orthopyroxene), iron-nickel alloy and troilite — iron sulfide, which is very rare in terrestrial rocks. It is no accident debris "Chelyabinsk" actively interested in foreign researchers of meteorites, for example, Japanese scientists at the disposal of the equipment for which there is a detailed isotopic analysis. Quite possibly, this equipment will help to talk about space "Aliens" a little more than we know today.
Right now, most researchers agree that the cosmic body, from which millions of years ago split "Chelyabinsk", was formed 4.5 billion years ago (that is, half a billion years older than the Earth) as a result of a natural process, that is, from the same cloud of gas and dust from which formed the Earth and other planets in the solar system. However, this does not mean that the basic science research fragments of the meteorite is useless. Useful, and how! First, the chondrites — a kind of "picture" of the first stage of the formation of cosmic objects. According to some astrophysicists, silicate chondrules (the main content of chondrites) were generated directly from the protoplanetary cloud surrounding the sun billions of years ago. Secondly, meteoritic iron from time immemorial, was quoted in metallurgy as the most "anti-corrosion".
The reason is simple: the cosmic iron, as opposed to an "industrial", and melts longer and longer cools down — sometimes for hundreds of millions of years, during which time it flies quietly in its orbit without undergoing the process of oxidation due to the complete absence of oxygen in a vacuum . Realizing what specific chemical processes lead to the creation of such wonder alloys, metallurgists will be able to create their counterparts in the earth, and the laboratory. At the very least, such a possibility is not ruled out Michael Oshtrakh in an interview with "BE."
