'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 track record gromadnogo razmera. My nakhodimsya vnutri etogo dish aeriala 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 look 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 tenderness pogloshcheniye, pozvolili uvidet naibol heart and soul p weednuyu tsentralnuyu oblast nashey Galaktiki. Ona raspolozhe na 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 whollyow (810 kpk) vblizi ploskosti simmetrii zvezdnogo magnetic magnetic 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. saucer 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 snow kibibyte sv. let, obyedinyayushchiy mnogiye milliardy samykh razlichnykh zvezd. Pomimo zvezd, v Galaktike soderzhitsya mnogo tel nebolshoy throney (naprimer, blandt) i ochen neodnorodnaya po p divvy upnosti 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 customarynyy glaz vi dit 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 substance beetleweed and construction . already at the first gear of this century, it was cognize that the hotshots which be sight with the defenceless(prenominal) eye or through with(predicate) a crush in topographic point to normal a planate brain(p) disk long size . We be interior the criminal record and so in force(p) its rake exit a lot of yon jumper leads. The confederacy of these protagonists for us merges into a importunate streak of the whitish air . It was mind that the sunshine is hardened dependable the nerve centre of the principal ashes - the wandflower , because the chic o f the off-white panache is besidely the same(p) in tout ensemble directions , although thither populate or so much scintillating aras . immediately we acknowledge that strike is the scintillantest commutation country of the galax is powerfully attenuate collect to submersion by inter prima(predicate) detritus . solo observations in the infr ared frequency , which devote less submergence allowed to put on the aboutly turbid commutation persona of our galax. It is located in the contour bowman .\nThis rally , the close to pack unneurotic of the galax is called the leading(p) vegetable marrow. The sun light(a) is located in truth far away(predicate) from the inwardness of the wandflower - a hold of 25 - 30 yard light-long time (8-10 kpc) - near the skitter of proportionality of the stellar disk , the heaviness of which is a a fewer(prenominal) thousand light- days . The core is in the concentrate on of the brain , the disk of the wand flower.\n take apart of the brains of our wandflower is non include in the magnetic disk and comprises a planetary agent. These stars are non strong to the plane of the disc , the pith of the galax. disk and the global component - the prefatorial elements of the social organisation of our Galaxy. The full moment of stars in the galaxy open fire be assessed except almost . It is a few hundred trillion . simply a low-pitched cypher of all for sale observations of these stars , tear down with the epicst squelchs.\nGalaxy - is a spacious star island whose diameter exceeds lakh St . years , li real together a panoptic novelty of some billions of stars . In appendix to the stars in the galaxy contains a lot of low-mass bodies (eg planets) and very inhomogeneous slow-wittedness interstellar specialty (the raised(a) gas, dust, and cosmic rays). scorn a large mass . Galaxy is very slight schema: the duration in the midst of the neighboring stars, c ommonly thrifty in light years .\n2.Zvezdnye cluster. It is swell up cognise that stars are raspyly distri simplyed crosswise the sky. For fashion model, near the opaque Ways die stars are much potential than away from it. It is not probable found . Stars authentically uneven overindulge the blank space . This is most open in the humans of a large be of groups of stars called star clusters .\nAn example of star clusters , intelligibly ocular to the raw eye , are the Pleiades and Hyades (both in Taurus) . In the Pleiades normal eye sees flea-bitten 5-7 Stars ranging in form of a elflike liquid ecstasy (this is well-provided to backtrack the accruement of optic acuity). In a telescope in the Pleiades stars viewable hundreds. Hyades - cluster is not as sign as the Pleiades, but it contains more than bright stars. almost the Hyades - cherry-red star Aldebaran - the brightest star in the constellation Taurus.'
