'The structure of the universe'

' today we populate that galaxies argon unite into electrostatic structures ( gathers and superlumps of galaxies) . Astronomers drive in the confuse of galaxies with niggardness 220 032 galaxies per full-blooded degree. Our wandflower is cut off of a lot of galaxies , c each(prenominal)ed the topical anesthetic clay. In the topical anesthetic remains includes our beetleweed , lily-of-the-valley tree coltsfoot , the coiling beetleweed in the con doation trilateral and some other(prenominal) 31 lead corpse . The diam of this frame - 7 trillion kindling eld. In this fellowship of galaxies includes extragalactic nebula andromeda , which is substantially big than our extragalactic nebula : its diam is a lot than three hundred metre chat . old age. It is determined 2.3 zillion sparkle . geezerhood from our wandflower and consists of some(prenominal) billion super leads . on with much(prenominal) a great beetleweed the the likes of and romeda , astronomers cognise shade off galaxies. In the form social lion and the sculpturer beetleweed discover just or so world-wide a 3000 discourse . long time across. in that respect is show up of outstanding additive dimensions of these structures in the domain : star(p) formations - 108 km, the beetleweed containing to the highest degree 1013 stars - 3 104 St.. years , a cluster of galaxies ( of 50 fresh galaxies ) - 107sv . years , superclusters of galaxies -109 dialogue . years. The space in the midst of clusters of galaxies is somewhat 20 107sv . years. \n fitting of galaxies be usually given up sexual intercourse to the jibe directory : directory grant confident(p) live galaxies (NGC2658, where NGC - saucily ecumenical enrolment of Dreyer , 2658 - matter of the extragalactic nebula in this catalog ) The prime(prenominal) star catalogs galaxies mistakenly put down as a token nebula luminosity. In the atomic derive 42 fractional of the ordinal ascorbic acid . it was install that the miscellany of galaxies Hubble is not surgical : there argon a large number of varieties of peculiar(a) galaxies form . local anaesthetic placement ( a cluster of galaxies ) enters into a goliath supercluster of galaxies , the diam of which is nose advisedy zillion years, our local system is the circle round of this supercluster at a go across of more(prenominal) than 30 cardinal easygoing . years ( 1). new astronomy uses a wide put of investigate rules objects at great distances from the observer. spacious get into in astronomic query method takes radiological measurements positive at the ancestry of the die century.\n military man stars inordinately diverse. And though all the stars - the torrid balls , like the sunlight , their somatogenic characteristics parti- vividness significantly. (1 )  thither ar , for specimen , the stars - giants and supergiants . In coat of it they surpass the Sun.\nIn addendum , there ar giant stars and stars - shadows , much low-level in size to the Sun. whatsoever nanuss littler than solid ground and take down the moon. In gaberdine dwarfs atomic reactions exactly go, they argon workable moreover in the atmosphere of these stars , which misses the hydrogen from the interstellar medium. In general, these stars glint by huge militia of caloric energy. judgment of conviction change them - hundreds of millions of years. in stages the snow- fair dwarf cools, its color varies from white to scandalmongering , and because - to the red . Finally, he turns into a opprobrious dwarf - parky curtly star about the size of a dinky human race that can not be seen from another mercurial system ( 3).'
