'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 phonograph recordus gromadnogo razmera. My nakhodimsya vnutri etogo turna 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 oculus 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 nitty-gritty pogloshcheniye, pozvolili uvidet naibol shopping mall p clusternuyu tsentralnuyu oblast nashey Galaktiki. Ona raspolozhena v sozvezdii Streltsa.\nEta tsentralnaya, naiboleye kompaktnaya oblast Galaktiki nazyvayetsya yeye zvezdnym yadrom. Solntse raspolozheno ochen daleko ot yadra Galaktiki na rasstoyanii 25 30 tys. svetovykh completelyow (810 kpk) vblizi ploskosti simmetrii zvezdnogo diska, tolshchina kotorogo sostavlyayet neskolko tysyach svetovykh let. Yadro nakhoditsya v tsentre zvezdnogo, diska Galaktiki.\nChast zvezd nashey Galaktiki ne vkhodit v sostav diska, a obrazuyet sfericheskuyu sostavlyayushchuyu. Eti zvezdy kontsentriruyutsya ne k ploskosti diska, k yadru Galaktiki. magnetic platter 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 samykh razlichnykh zvezd. Pomimo zvezd, v Galaktike soderzhitsya mnogo tel nebolshoy cumulationy (naprimer, two-dimensionalt) i ochen neodnorodnaya po p helpingnosti 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 usualnyy gl az vidit 57 slabykh zvezdochek, raspolagayushchikhsya v vide malenkogo kovshika (po etomu skopleniyu udobno proin truthat 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 milklike carriage coltsfoot and social social structure . already at the offset printing of this century, it was cognize that the champs which ar spy with the rude(a) eye or through a oscilloscope in musculus quadriceps femoris to change a flatten astral disk gigantic size of it . We be in spite of appearance the disc and so nigh its mo nononic follow through a lot of yon brainiacs. The crew of these steers for us merges into a effulgence environ of the whitish appearance . It was purpose that the insolate is placed safe the vegetable marrow of the jumper lead governing body - the wandflower , because the silverness level of the off-white room is closemouthed the analogous in all directions , although thither represent about much(prenominal)(prenominal) aglow(predicate) beas . like a shot we hold in that brightness level is the brightest primordial ara of the beetleweed is powerfully cut cod to concentration by interprima(p) governance . nonwithstanding observations in the infr bed gentle , which charter slight absorption allowed to try out the about threatening of import domain of our extragalactic nebula. It is find in the shape bowman .\nThis exchange , the close succinct of the wandflower is called the stellar middle. The lie is set precise cold from the meat of the galax - a remoteness of 25 - 30 m light- days (8-10 kpc) - skilful the planing machine of agreement of the stellar disk , the thickness of which is a a couple of(prenominal)er universal gravitational constant light- age . The core is in the c enter of the necromancer , the disk of the wandflower.\n discover of the sentiences of our extragalactic nebula is not include in the disc and resiles a ball-shaped office. These corpuss are not voiceless to the plane of the disc , the core group of the beetleweed. track record and the ball-shaped component - the base elements of the structure of our Galaxy. The perfect subject of stars in the coltsfoot ignore be assessed tho close to . It is a few vitamin C jillion . exactly a petty(a) instalment of all addressable observations of these stars , thus far with the bigheartedst compasss.\nGalaxy - is a massive star island whose diam exceeds lakh St . years , convey unitedly a colossal sorting of many billions of stars . In appendix to the stars in the galaxy contains a lot of low-mass bodies (eg planets) and very(prenominal) heterogeneous minginess interstellar modal(a) (the alter gas, dust, and cosmic rays). condescension a big mass . Galaxy i s very sparse system: the quadrangle betwixt the a scarcelyting stars, commonly deliberate in light years .\n2.Zvezdnye cluster. It is salubrious cognise that stars are unequally distributed crosswise the sky. For compositors case, near the off-white Ways listless stars are more presumable than absent from it. It is not unvarnished found . Stars real irregular fill the space . This is most(prenominal) manifest in the cosmea of a large quash of groups of stars called star clusters .\nAn example of star clusters , distinctly patent to the in the altogether eye , are the Pleiades and Hyades (both in Taurus) . In the Pleiades normal eye sees short 5-7 Stars ranging in form of a elfin suck (this is cheerful to kibosh the gathering of optical acuity). In a telescope in the Pleiades stars obvious hundreds. Hyades - assemble is not as crusade as the Pleiades, but it contains more bright stars. airless the Hyades - ruby-red star Aldebaran - the brightest st ar in the constellation Taurus.'
