<< Vchera 22.02.1999 Zavtra >>
NGC 1316: Posle stolknoveniya galaktik
Avtory i prava: Grilmer (Analiticheskii centr po obrabotke infrakrasnyh nablyudenii/Kaliforniiskii tehnologicheskii institut) i dr., Shirokougol'naya planetnaya kamera 2, kosmicheskii teleskop im. Habbla, NASA
Poyasnenie: Chtoby ponyat', chto proishodit v takom tainstvennom meste, kak naprimer, NGC 1316, astronomy vynuzhdeny upodobit'sya syshikam. Predvaritel'noe rassledovanie pokazalo, chto ob'ekt NGC 1316 predstavlyaet soboi gigantskuyu ellipticheskuyu galaktiku, kotoraya 100 millionov let nazad nachala pogloshat' men'shuyu sosednyuyu spiral'nuyu galaktiku. Svidetel'stvom, odnoznachno govoryashim o prisutstvii spiral'noi galaktiki, yavlyaetsya nalichie temnyh pylevyh vkraplenii. Naryadu s prochimi zagadkami, ostaetsya neponyatnym pochemu sharovye zvezdnye skopleniya, kotorye vidny kak slabye tochki na fotografii, takie malen'kie. Bol'shinstvo ellipticheskih galaktik, po sravneniyu s NGC 1316, imeyut bol'shee chislo i bolee yarkie sharovye skopleniya. Po vozrastu nablyudaemyh sharovyh skoplenii nel'zya skazat', chto oni obrazovalis' v rezul'tate nedavnego stolknoveniya galaktik; soglasno odnoi teorii, eti sharovye skopleniya na samom dele naselyali galaktiku, kotoraya teper' vhodit v sostav NGC 1316.
