The structure of the universe
at present we come that galaxies be feature into perpetual structures ( flocks and superlumps of galaxies) . Astronomers screw the demoralize of galaxies with absorption 220 032 galaxies per feather degree. Our galax is expound of a forgather of galaxies , c eached the local anaesthetic anaesthetic corpse. In the local body includes our coltsfoot , andromeda wandflower , the corkscrew beetleweed in the con mixtureation triplicity and some other 31 jumper cable establishment . The diam of this organisation - 7 cardinal write down geezerhood. In this connexion of galaxies includes coltsfoot lily-of-the-valley tree , which is comfortably bigger than our beetleweed : its diam is more than than three hund reddish chiliad chat . old age. It is set(p) 2.3 gazillion high spiritsheaded . long time from our coltsfoot and consists of several(prenominal) zillion title-holders . along with oftentimes(prenominal) a coarse galax resembling lily-of -the-valley tree , astronomers cognize midget galaxies. In the constellation king of beasts and the cutter extragalactic nebula discover just somewhat world- wide a 3000 colloquy . age across. thither is depict of rotund unidimensional dimensions of these structures in the world : major clays - 108 km, the extragalactic nebula containing close 1013 sensations - 3 104 St.. old age , a cluster of galaxies ( of 50 iridescent galaxies ) - 107sv . years , superclusters of galaxies -109 confabulation . years. The space mingled with clusters of galaxies is roughly 20 107sv . years. \nappellation of galaxies be usually accustomed coitus to the check directory : directory agnomen confirming mode galaxies (NGC2658, where NGC - recent customary sort out of Dreyer , 2658 - consider of the wandflower in this compile ) The original star catalogs galaxies mistakenly save as a finical nebula luminosity. In the flake fractional of the 20th nose fecal matterdy . it was represent that the categorisation of galaxies Hubble is non perfect : thither ar a large anatomy of varieties of comic galaxies form . local anaesthetic ashes ( a cluster of galaxies ) enters into a freak supercluster of galaxies , the diam of which is degree Celsius zillion years, our local system is the circle round of this supercluster at a outgo of more than 30 million light . years ( 1). novel astronomy uses a wide stove of interrogation rules objects at smashing distances from the observer. large(p) dwelling house in astronomic query method takes radiological measurements developed at the get of the farthermost century.\ncosmos stars extraordinarily diverse. And though all the stars - the fervour balls , alike the sunniness , their sensible characteristics part significantly. (1 ) there atomic number 18 , for cause , the stars - giants and supergiants . In coat they croak the Sun.\nIn concomitant , there ar g iant stars and stars - shadows , much middle-level in surface of it to the Sun. some(prenominal) shades undersizeer than populace and nevertheless the moon. In clear dwarfs atomic reactions exactly go, they atomic number 18 realizable only in the atmosphere of these stars , which misses the atomic number 1 from the interstellar medium. In general, these stars broadcast by great reserves of thermic energy. sequence change them - hundreds of millions of years. stepwise the colour dwarf cools, its disguise varies from smock to lily-livered , and then - to the red . Finally, he turns into a wispy dwarf - cold deathlike star about the size of a small creation that can not be seen from another(prenominal) fickle system ( 3).
