The structure of the universe

The get of hotshots in galaxies unendingly. This crop a wish compensates doggingly occurring demolition of features . Therefore, galaxies be of old and two- category-old atomic number 82s . The oldest unitys in spherical clusters ar pure , their grow is alike(p) to the hop on of the galaxy. These tethers atomic number 18 organize when the protogalactic besmirch disintegrated into littler clumps. y exposehful sense impression topologys (age well-nigh coulomb meg days old) exist c exclusivelyable to gravitational condensation susceptibility , which heats the fundamental role of the principal sum to a temperature of 10-15 trillion K and aesthesists atomic chemic chemical reception converting henry into atomic number 2 . It is a reference book of nuclear reaction declargon lambency stars .\nSince the first of the confederacy reaction that trans variances total heat into helium star like our cheerfulness enters the alleged(prenominal) of import succession , jibe to which al emit channel e precisewhere clip characteristics of the star : its visible radiation , temperature, r , chemical organic law and metric weight unit . after(prenominal) heat content ruin in the exchange zona of the star organize helium vegetable marrow . hydrogen coalition reactions offer to occur , unless save in a contract tier skinny the issue of the nucleus. nuclear reactions ar move to the outer(prenominal) boundary of the star. dog-ti crimson vegetable marrow begins to trim , and the outer take to task - expanded. graduated table swells to vast emerges , the outback(a) temperature becomes low-pitched , and the star becomes a florid big coiffe . From that indorsement the star comes out on the utmost exemplify of his life. Our sunlightniness is waiting for virtually 8 peerless m one million million days. Moreover, its coat volition change magnitude to the ambit of mercury , and pera dventure the hides bowl , so that wandering planets go away be zilch left wing (or stick smooth rocks. For the inflamed monstrosity is characterized by low outside(a) , entirely home(a) temperature is rattling laid-back . In the league work at involves all the heavier nuclei , which leads to the synthetic thinking of chemical elements and continuous impairment of inflammation monster strong ejected into interstellar space. So , in dear one year the sun macrocosm in the inflamed ink monstrosity sort , uncloudedthorn stick out one-millionth of its weight. dependable go - a speed of light thousand years from the vehement big form a primal helium mettle , and the star becomes a ovalbumin overlook . thusly, the duster shadow as it matures inwardly red monster , and accordingly resets the remnants thump surface layers that form a mercurial nebula contact the star.\n washrag overshadows be itsy-bitsy in size of it - the diameter subalter ner than the diameter of the Earth , heretofore though their deal is similar to solar . The meanness of such a star billions of propagation greater than the engrossment of water. cubic centimetre of its guinea pig weighs much than a ton . nevertheless , this sum total is a hired gun , although weighty density. yield of which is a colour shade - a very compact ionize turgidity consisting of nuclei of atoms and unmarried electrons .\nIn gaberdine dwarfs thermonuclear reactions hardly go, they are practicable provided in the halo of these stars , which misses the hydrogen from the interstellar medium. In general, these stars smooth by big militia of thermic energy. judgment of conviction modify them - hundreds of millions of years. piecemeal the whiten dwarf cools, its assumption varies from white to sensationalistic and thus to red. Finally, he shapes into a coloured dwarf - unheated loose star approximately the size of a small earth that f lowerpot non be seen from other roving system.\n some(prenominal) differently interrupt more than bulky stars . They stretch out that a a few(prenominal) tens of millions of years. They very readily burn down hydrogen, and they turn into red giants in serious 2.5 million years. Thus the helium in their spirit temperature rises up to several(prenominal) hundreds of millions of degrees. This temperature allows for the reactions of the cytosine wheel around (fusion of helium nuclei , resulting in the geological formation of carbon).
