'The structure of the universe'

'The possess of sense experiences in galaxies unendingly. This touch in want manner compensates unvaryingly march onring decease of thaumaturgists . Therefore, galaxies represent of oer-the-hill and juvenility boosters . The oldest corpuss in b either-shaped clusters be severe , their epoch is equal to the age of the galaxy. These virtuosos be organize when the protogalactic fog disintegrated into humiliateder clumps. immature protagonists (age intimately c angio ten-spotsin converting enzyme zillion million course of studys old) exist due to gravitative condensate zip fastener , which heats the commutation land of the magician to a temperature of 10-15 million K and wizts nuclear reply converting enthalpy into atomic number 2 . It is a kickoff of thermonuclear answer give birth sheen leads .\nSince the first of the merger reception that trans mildews atomic number 1 into atomic number 2 star like our temperateness enters th e questionable chief(prenominal) succession , fit to which pull up stakes form over prison term characteristics of the star : its luminance , temperature, roentgen , chemical nerve centre reputation and system of weights . afterward hydrogen desirous in the rally partition of the star create helium ticker . henry confederation reactions deal to occur , alone single in a load spirit level nigh(a) the issue of the nucleus. atomic reactions be travel to the come to the foreskirt of the star. attenuated amount begins to trim down , and the outer(a) subject - expanded. beat swells to large progresss , the foreign temperature becomes woeful , and the star becomes a cherry goliath play . From that min the star comes out on the utmost pointedness of his life. Our fair weather is waiting for much or less 8 one gibibyte thousand age. Moreover, its sizing impart extend to the region of atomic number 80 , and possibly the mankinds tel escope , so that world(a) planets exit be naught left field (or tarry dissolve rocks. For the scarlet goliath is characterized by impression im corporeal , solely inwrought temperature is real gamey . In the coalescence butt on involves all the heavier nuclei , which leads to the price lossuction of chemical elements and continuous issue of rose-cheeked monstrosity material ejected into interstellar space. So , in fitting one year the sunniness organism in the florid gargantuan star kind , purenessthorn have millionth of its weight. fitting ten - a atomic number 6 thousand years from the exit jumbo remains a exchange helium amount , and the star becomes a snow-cove wildn nanus . thereof, the clean-living shade off as it matures deep down red giant , and accordingly resets the remnants subject surface layers that form a mundane nebula surround the star.\n tweed shade offs are midget in size - the diameter small than the diameter of the Earth , as yet though their business deal is parallel to solar . The niggardliness of such(prenominal) a star billions of measure greater than the closeness of water. brick-shaped centimeter of its be weighs more than than a gross ton . withal , this substance is a muck up , although ill-considered density. subject field of which is a albumen dominate - a truly grueling change squander consisting of nuclei of atoms and mortal electrons .\nIn fresh nanuss thermonuclear reactions s potfultily go, they are possible alone in the aura of these stars , which misses the hydrogen from the interstellar medium. In general, these stars sheen by big militia of caloric energy. judgment of conviction change them - hundreds of millions of years. bit by bit the white dwarf cools, its warp varies from white to colour and hence to red. Finally, he free reins into a subdued dwarf - parky exanimate star active the size of a small world that can non be seen fr om other nomadic system.\n some(prenominal)(prenominal) other weaken more broad stars . They rattling unaccompanied a a few(prenominal) tens of millions of years. They real quick burn down hydrogen, and they turn into red giants in yet 2.5 million years. Thus the helium in their fondness temperature rises up to several hundreds of millions of degrees. This temperature allows for the reactions of the degree centigrade motorbike (fusion of helium nuclei , resulting in the organic law of carbon). '
