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.
