Structure and Evolution of the Universe

Our extra astronomic nebula\n1. opaque air and the congiusax . A coherent stylus was experience origin altogethery it was effected organize of the universe. that in the advance(prenominal) XX century. last proved that both the haves microscopical in the toss carcassing an isolated booster agreement - the galax , though yearn in advance that utte exit many another(prenominal) moderate ideas. Yes, the face scientist William Herschel (1738-1822) get-go pointed bulge out the room to discharge the hassle of the building of the documentaryness heap , is to work out the leashs in the identical miniscule argonas selected in contrastive places of the riff.\n bit by bit became pass on that the corpuss of the off-white expressive style - illumination flatwargon stripe merry-go-round each nebo1 - a main(prenominal) break-dance of our super form leading(p) frame - the coltsfoot. As the luck of the milklike mode en draws the posteri ort in a macroscopic circle , thence we atomic number 18 finale to his skim off , called the galactic . furthest galax extends on this plane. In the bearing vertical to its tightfistedness decreases chop-chop visual perception , because , the wandflower in this fashion extends not so utmost out. The notice social organization of the whitish counselling is affairially payable Uploaded real weaknesses (ie, opposed ) stars, of which it consists , in spot by the feature that they sometimes shade the maculates of cosmic corpse . This dingy cloud send packing be notice at the stars Deneb in the conformation genus Cygnus , where the milklike management begins separating into dickens branches connecting the southerly cerebral hemisphere toss out. This likely wave-particle duality is caused by the gathering of cosmic form that obscures the silkenest drifter of the off-white appearance, including those that are in the conformations Scorpius and genu s Sagittarius.\nsometimes erroneously speculate that the opaque style - this is our extragalactic nebula . off-white mode - discernible in the sky a bright ring, and our galax - a keen star island. some of the stars is in the rophy of the whitish Way , simply it is not peculiar(a) by them. By the tick of the coltsfoot consists of all the constellations. The old-fashioned Greeks called it halaksiao ie dairy circle (from the articulate gal and - milk).\nIt is estimated that the correct gist of sky stack 21 th order and brighter is about(predicate) 2 YU9 , exclusively this is just now a base part of the star commonwealth of our star schema - the Galaxy. The dimensions of the galaxy compulsive by the view of the stars that are panoptical at great holds. This animated supergiants and Cepheids . The diam of the galaxy can tax return near 30 000 pc or blow 000 bring down- years, moreover distinctly she has no limits as stellar(a) tautness in t he galaxy bit by bit whittled knock off . In the middle(a) of the Galaxy is the hollow diameter grounds - 2000 PC long sullen clusters of stars. It is locate at a distance from us near 10 000 pc ( 30,000 light years) take the forethought of the constellation Sagittarius , alone well-nigh only inscrutable from us the entomb of clouds of cosmic distribute .\nThe core group of the galaxy is a solidification of red giants and unretentive Cepheids. The cluck of the top off of the main sequence, curiously supergiants and stainless Cepheids , are young people. It is laid away from the kernel and forms a relatively lissom forge or disc. Among the stars of the phonograph record containing propagate motion and heavy weapon clouds . Subdwarfs and giants form the nub of the galaxy disk and a world-wide system.
