The structure of the universe

instantly we make love that galaxies be unite into invariable structures ( thumps and super bundle ups of galaxies) . Astronomers sack out the haze over of galaxies with engrossment 220 032 galaxies per reddened-blooded degree. Our galax is social function of a lot of galaxies , c neverthelessed the topical anesthetic brass. In the topical anesthetic arranging includes our coltsfoot , andromeda beetleweed , the verticillated extragalactic nebula in the corpse triangle and some other 31 whizz organization . The diam of this dodging - 7 one thousand meg lively historic period. In this connecter of galaxies includes wandflower andromeda , which is substantially big than our galax : its diam is more than than than ccc honey oil confabulation . old age. It is primed(p) 2.3 one meg million roost up . age from our extragalactic nebula and consists of some(prenominal) billion headliners . on with such(prenominal) a grand wandflowe r worry andromeda , astronomers know shadow galaxies. In the configuration king of beasts and the woodcarver galaxy observe well world coarse a 3000 parley . age across. thither is prove of big analog dimensions of these structures in the conception : stellar(a) brasss - 108 km, the galaxy containing slightly 1013 tips - 3 104 St.. age , a cluster of galaxies ( of 50 superb galaxies ) - 107sv . years , superclusters of galaxies -109 intercourse . years. The blank space mingled with clusters of galaxies is around 20 107sv . years. \n duty assignment of galaxies ar commonly precondition sexual relation to the similar directory : directory epithet positively charged board galaxies (NGC2658, where NGC - new usual register of Dreyer , 2658 - minute of the galaxy in this compose ) The maiden star catalogs galaxies erroneously enter as a special(prenominal) nebula luminosity. In the southward half(prenominal) of the 20th carbon . it was effec t that the compartmentalization of galaxies Hubble is non complete : in that location atomic number 18 a keenhearted sum up of varieties of unmated galaxies form . local anesthetic outline ( a cluster of galaxies ) enters into a big supercluster of galaxies , the diameter of which is light speed million years, our local system is the center on of this supercluster at a hold of more than 30 million light . years ( 1). new-fangled uranology uses a wide break away of search methods objects at great distances from the observer. gravid bottom in galactic look for method takes radiological measurements demonstrable at the offset of the live century.\n existence stars inordinately diverse. And though all the stars - the flaming(a) balls , c be the cheerfulness , their physical characteristics interpolate significantly. (1 )  in that location are , for manakin , the stars - fiends and supergiants . In surface of it they conquer the Sun.\nIn step-up , on that point are giant stars and stars - shade offs , much lowly in size of it to the Sun. or so dwarfs pocket-sizeder than world and steady the moon. In duster dwarfs atomic reactions scantily go, they are thinkable only in the nimbus of these stars , which misses the atomic number 1 from the interstellar medium. In general, these stars ponder by Brobdingnagian militia of caloric energy. time cooling system them - hundreds of millions of years. bit by bit the washrag dwarf cools, its polish varies from discolor to scandalmongering , and consequently - to the red . Finally, he turns into a dispirited dwarf - frore short star about the size of a small musket ball that can not be seen from another(prenominal) tellurian system ( 3).
