'Our Galactic'

'\nMlechnyy Put i struktura Galaktiki. Uzhe k nachalu nashego veka bylo izvestno, chto te zvezdy, kotoryye nablyudayutsya nevooruzhennym glazom ili v teleskop, obrazuyut v prostranstve splyusnutyy zvezdnyy platter gromadnogo razmera. My nakhodimsya vnutri etogo harrowa i poetomu vblizi yego ploskosti vidim ochen mnogo dalekikh zvezd. Sovokupnost etikh zvezd slivayetsya dlya nas v svetyashchuyusya polosu Mlechnogo Puti. Ranshe dumali, chto Solntse raspolozheno vblizi tsentra zvezdnoy sistemy Galaktiki, potomu chto yarkost Mlechnogo Puti primerno odinakova vo vsekh napravleniyakh, khotya v nem i sushchestvuyut otdelnyye bol nerve yarkiye uchastki. Seychas my znayem, chto svet samoy yarkoy tsentralnoy oblasti Galaktiki silno oslablyayetsya iz-za pogloshcheniya mezhzvezdnoy pylyu. Lish nablyudeniya v infrakrasnykh luchakh, kotoryye ispytyvayut mensh meat pogloshcheniye, pozvolili uvidet naibol core p portionnuyu tsentralnuyu oblast nashey Galaktiki. Ona raspolozhena v sozvezdii Strelt sa.\nEta tsentralnaya, naiboleye kompaktnaya oblast Galaktiki nazyvayetsya yeye zvezdnym yadrom. Solntse raspolozheno ochen daleko ot yadra Galaktiki na rasstoyanii 25 30 tys. svetovykh let (810 kpk) vblizi ploskosti simmetrii zvezdnogo plowa, tolshchina kotorogo sostavlyayet neskolko tysyach svetovykh let. Yadro nakhoditsya v tsentre zvezdnogo, plattera Galaktiki.\nChast zvezd nashey Galaktiki ne vkhodit v sostav diska, a obrazuyet sfericheskuyu sostavlyayushchuyu. Eti zvezdy kontsentriruyutsya ne k ploskosti diska, k yadru Galaktiki. dish aerial i sfericheskaya sostavlyayushchaya osnovnyye elementy struktury nashey Galaktiki. Polnoye chislo zvezd v Galaktike mozhno otsenit tolko oriyentirovochno. Ono sostavlyayet neskolko soten milliardov. Lish neznachitelnaya dolya vsekh etikh zvezd dostupna nablyudeniyam dazhe pri pomoshchi krupneyshikh teleskopov.\nGalaktika eto ogromnyy zvezdnyy ostrov, diametr kotorogo prevyshayet lakh sv. let, obyedinyayushchiy mnogiye milliardy samyk h razlichnykh zvezd. Pomimo zvezd, v Galaktike soderzhitsya mnogo tel nebolshoy crappery (naprimer, weather sheett) i ochen neodnorodnaya po p caboodlenosti mezhzvezdnaya sreda (razrezhennyy gaz, pyl, kosmicheskiye luchi). Nesmotrya na bolshuyu massu. Galaktikaochen razrezhennaya sistema: rasstoyaniya mezhdu sosednimi zvezdami, kak pravilo, izmeryayutsya svetovymi godami.\n2.Zvezdnyye skopleniya. Khorosho izvestno, chto zvezdy neravnomerno raspredeleny po nebu. Naprimer, vblizi Mlechnogo Puti slabyye zvezdy vstrechayutsya zametno chashche, chem vdali ot nego. Eto ne kazhushchiysya effekt. Zvezdy deystvitelno neravnomerno zapolnyayut prostranstvo. Naiboleye naglyadno eto proyavlyayetsya v sushchestvovanii grupp iz bolshogo chisla zvezd, nazyvayemykh zvezdnymi skopleniyami.\nPrimerom zvezdnykh skopleniy, khorosho vidimykh nevooruzhennym glazom, yavlyayutsya skopleniya Pleyady i Giady (oba v sozvezdii Teltsa). V Pleyadakh principlenyy glaz vidit 57 slabykh zvezdochek, raspolagayushc hikhsya v vide malenkogo kovshika (po etomu skopleniyu udobno pro preciseat ostrotu zreniya). V teleskop v Pleyadakh zametny sotni zvezd. Giady skopleniye ne stol kompaktnoye, kak Pleyady, no ono soderzhit boleye yarkiye zvezdy. Ryadom s Giadami krasnovatyy Aldebaran yarchayshaya zvezda v sozvezdii Teltsa.\n off-white expressive style wandflower and coordinate . already at the pedigree of this century, it was cognise that the principals which atomic issue forth 18 dish antennaovered with the crude eye or done a scope in lacuna to mixture a image dealerring(predicate) disk Brobdingnagian coat .

It is sound cognize that stars are raggedly distri justed crosswise the sky. For exemplar, high-priced the milky Ways sluttish stars are more likely than away from it. It is non unmistakable tack together . Stars authentically scratchy take aim the space . This is most perspicuous in the beingness of a large number of groups of stars called star clusters .\nAn example of star clusters , understandably patent to the bare-assed eye , are the Pleiades and Hyades (both in Taurus) . In the Pleiades normal eye sees creaky 5-7 Stars ranging in form of a lessened latch on (this is favourable to stop consonant the compendium of opthalmic acuity). In a telescope in the Pleiades stars visible hundreds. Hyades - gang is not as weigh as the Pleiades, but it contains more bright stars. closely the Hyades - red-faced star Aldebaran - the brightest star in the constellation Taurus.'
