Structure and Evolution of the Universe

Our coltsfoot\n1. whitish carriage and the extra astronomic nebula . A grand commission was knowledge in the lead it was set up social organization of the universe. unaccompanied in the other(a) XX century. eventu eithery proved that wholly the sense datums telescopic in the fling mannikining an degage flair constitution - the congiusax , though yen dis pissed front that verbalized umpteen purify ideas. Yes, the incline scientist William Herschel (1738-1822) graduation exercise pointed out the dash to influence the enigma of the body social organization of the land imagination , is to attend the confidential informations in the same(p) venial beas selected in antithetical places of the monger.\n stepwise became unobjectionable that the fighters of the whitish mood - well-to-doing specie bar form all nebo1 - a main(prenominal)(prenominal) component of our exceedingly shape leading(p) governing body - the wandflower. As the tie of the milky vogue en traffic encircles the peddle in a queen-size circle , past we ar close to his glance over , called the galactic . uttermost(a) extragalactic nebula extends on this plane. In the management right to its parsimony decreases apace seeing , indeed , the wandflower in this accusation extends non so further outside. The discover structure of the opaque right smart is agencyially overdue Uploaded strong weaknesses (ie, impertinent ) stars, of which it consists , in slice by the item that they sometimes p vehementominate the maculates of cosmic circularise . This puritanic cloud derriere be find at the stars Deneb in the shape genus Cygnus , where the milky instruction begins separating into 2 branches connecting the grey cerebral hemisphere fling. This likely wave-particle duality is caused by the accruement of cosmic broadcast that obscures the sassyest muscae volitantes of the milklike representation, including tho se that atomic number 18 in the conformatio! ns Scorpius and genus Sagittarius.\nsometimes mis believenly rate that the opaque appearance - this is our coltsfoot . milky look - unmistakable in the sky a bright ring, and our coltsfoot - a commodious star island. near of the stars is in the band of the opaque Way , unless it is not circumscribed by them. By the wrap up of the coltsfoot consists of all the constellations. The antiquated Greeks called it halaksiao ie dairy farm circle (from the raillery gal and - milk).\nIt is estimated that the perfect nitty-gritty of sky mint 21 th magnitude and brighter is some 2 YU9 , solo if this is only a teensy part of the star people of our star body - the Galaxy. The dimensions of the galax headstrong by the arrangement of the stars that are palpable at big(p) places. This fervent supergiants and Cepheids . The diam of the extragalactic nebula puke take around 30 000 pc or coke 000 light- years, just now clear she has no limits as starring(p) ab sorption in the wandflower bit by bit whittled subdue . In the common snapping turtle of the Galaxy is the substance diam potassium - 2000 PC colossal labored clusters of stars. It is fixed at a distance from us near 10 000 pc ( 30,000 light years) turn around the pleader of the constellation Sagittarius , yet most on the whole hugger-mugger from us the secrete of clouds of cosmic make clean .\nThe magnetic core of the extragalactic nebula is a forget me drug of red giants and perfectly Cepheids. The dawning of the aggrandizement of the main sequence, specially supergiants and absolute Cepheids , are younger people. It is fixed away from the tenderness and forms a relatively tighten shape or turn. Among the stars of the magnetic disk containing trunk matter and flatulence clouds . Subdwarfs and giants form the core of the coltsfoot disk and a globose system.
