Mlechnyi Put' - spiral' s peremychkoi
Avtory i prava: GLIMPSE Team
Perevod: D.Yu.Cvetkov
Poyasnenie: Obzor zvezd, nedavno osushestvlennyi kosmicheskim teleskopom Spitcera, ubezhdaet astronomov, chto nash Mlechnyi Put' - ne obyknovennaya spiral'naya galaktika. Nahodyas' vnutri diska Galaktiki, ochen' trudno opredelit' istinnuyu strukturu nashego Mlechnogo Puti. Odnako perepis' okolo 30 millionov zvezd v infrakrasnom svete pokazyvaet, chto otlichitel'noi osobennost'yu Galaktiki yavlyaetsya ochen' bol'shaya central'naya peremychka, ili bar, dlinoi primerno v 27 tysyach svetovyh let. Deistvitel'no, s tochek zreniya, otkuda nasha Galaktika vidna plashmya, astronomy v dalekih galaktikah, vozmozhno, uvidyat zamechatel'nuyu spiral'nuyu galaktiku s peremychkoi, kakoi hudozhnik predstavil ee sebe na etoi kartinke. Esli predydushie issledovaniya obnaruzhivali nebol'shuyu central'nuyu peremychku, novye rezul'taty svidetel'stvuyut, chto napravlenie bol'shogo central'nogo bara v Mlechnom Puti sostavlyaet ugol primerno v 45 gradusov s liniei, soedinyayushei Solnce i centr Galaktiki. Ne vpadaite v paniku ... astronomy vse eshe schitayut, chto Solnce nahoditsya za predelami oblasti central'nogo bara, a rasstoyanie ot Solnca do vneshnego kraya Mlechnogo Puti sostavlyaet primerno tret' ego radiusa.
