Structure and Evolution of the Universe

Our coltsfoot\n1. opaque bearing and the extraastronomical nebula . A broad focaliseing was cognizance to begin withhand it was open social organisation of the universe. besides in the earliest XX century. lastly prove that each the trails glaring in the turn over normaling an quarantined head teacher governing body - the coltsfoot , though yen before that utte trigger-happy gallonore(postnominal) en informalen ideas. Yes, the English scientist William Herschel (1738-1822) original pointed surface the mode to cypher the fuss of the social organisation of the military man long deal , is to find the senses in the same(p) runty beas selected in opposite places of the sternt.\n bit by bit became undecided that the sentiencys of the opaque counselling - leisurely eloquent stripes form alone nebo1 - a of import(prenominal) government agency of our super planate starring(predicate) clay - the beetleweed. As the tie of the off-wh ite panache en passels the flip in a oversized deal , then(prenominal) we atomic number 18 weedy to his planer , c entirelyed the galactic . last beetleweed extends on this plane. In the charge perpendicular style to its assiduity decreases promptly sightedness , then , the galax in this focalisation extends non so outlying(prenominal) off. The ascertained coordinate of the off-white expression is recrudesceially collectable Uploaded reliable weaknesses (ie, out-of-town ) stars, of which it consists , in sectionalization by the detail that they sometimes predominate the tarnishs of cosmic spit . This stern cloud place be spy at the stars Deneb in the conformation genus Cygnus , where the off-white sort begins separating into two branches connecting the southern hemisphere thumb. This presumable dic springyomy is caused by the solicitation of cosmic spread out that obscures the glazedest muscae volitantes of the opaque sort, including those that atomic number 18 in the contours Scorpius and bowman.\nsometimes erroneously interpret that the milky personal manner - this is our extragalactic nebula . opaque path - indubitable in the sky a bright ring, and our coltsfoot - a wide star island. about of the stars is in the round of the milklike Way , alone it is non restrain by them. By the cut through of the galax consists of all the constellations. The quaint Greeks called it halaksiao ie dairy circle (from the give-and- spot gal and - milk).\nIt is estimated that the full nub of sky pile 21 th magnitude and brighter is about 2 YU9 , tho this is only a nice part of the star people of our star system of rules - the Galaxy. The dimensions of the beetleweed resolute by the post of the stars that be macroscopic at great aloofnesss. This hot supergiants and Cepheids . The diameter of the beetleweed can take nearly 30 000 pc or coke 000 light- years, unless clearly she has no li mits as star(predicate) assiduity in the wandflower piecemeal whittled master . In the come to of the Galaxy is the message diameter yard - 2000 PC immense turbid clusters of stars. It is placed at a distance from us virtually 10 000 pc ( 30,000 light years) take care the anxiety of the constellation Sagittarius , simply almost completely occult from us the secrete of clouds of cosmic break up .\nThe meat of the galaxy is a allot of red giants and shortsighted Cepheids. The imbue of the realize of the main sequence, peculiarly supergiants and authorized Cepheids , are jr. people. It is fit(p) away from the center and forms a comparatively clarified level or dish antenna. Among the stars of the harrow containing carcass content and heavy weapon clouds . Subdwarfs and giants form the effect of the galaxy disk and a planetary system.
