The temperature in the Cosmos

filmmakers and science fiction writers are constantly trying to prove to us that the man who suddenly got into open space without a spacesuit, will die in a split second.They claimed the temperature in space is that no living creature without special equipment is not able to stay in the open space of the universe more than a second.For example, it is quite interesting and vividly written in one of the works of Arthur C. Clarke: the hero, trapped in outer space, instantly killed due to severe frosts and internal pressure.However, according to theoretical calculations of modern scientists, the death of a person in such circumstances is not coming immediately.

often suggests that the man, who turned out in the open air space will be broken dramatically increase the pressure inside.Cosmos - a perfect vacuum in the human body is supported by a pressure of approximately one atmosphere.At first glance it may seem that such a resonance enough to living being instantly killed by the "explosion".

Indeed, no "explosion" will not occur - the body tissue characterized by sufficient strength and are able to handle the pressure of one atmosphere.Instead of the expected reaction occurs quite different: bursting the capillaries that supply blood to the skin, it is quite an unpleasant phenomenon, but not deadly.

Another reason because of which a person can die very quickly in the open space of the universe - the temperature of the cosmos itself, which, according to some estimates reach absolute zero Kelvin (-273,15 ° C).To be more precise, so people think, knowing nothing about the peculiarities of the temperature of interplanetary space.The temperature in the open space, strange as it sounds - it is the lack of any temperature.Space, according to the researchers, has no temperature accordingly, it can not neither heat nor cool located therein a living organism.

is traditionally meant by terms such as "temperature"?Firstly - the chaotic motion of the atoms or molecules that make up everything the body.The more intense the molecules move, so, consequently, higher the thermometer.Where the substance itself is not, there can be no question of such a thing, and the temperature.Outer space - is just such a place where matter very little.Therefore, they say, that the temperature in space - it is a complete lack thereof.However, the body, which are in interplanetary space, have very different thermal indices, which depend on the set of all possible parameters.

Outer space is filled with radiation sources having the most diverse intensity and frequency.And the temperature in space, from this viewpoint, it is understood as the total energy of radiation in a specific location in space.

thermometer in the open space at first will show the temperature, which was characteristic of the environment from which it is extracted, for example, from the interior of the spacecraft.Over time, the unit will heat up, and very strong.Indeed, in circumstances where there is a convective heat transfer, the objects lying in direct sunlight, heat strong enough so that it is impossible to touch.In Space heating will be a much stronger as a vacuum - this is the perfect thermal insulator.

Thus, the temperature in space - a relative term, but depending on to what point in space is the body, it can be heated or cooled.Away from the stars, there where practically do not penetrate the heat flows, the temperature of the body is equal to about 2,725 degrees Kelvin, as the cosmic microwave background radiation is distributed in all parts of the universe known to astronomers, but the approach to the body of a star, it will gradually increase.
