NGC 1275: stolknovenie galaktik
Avtory i prava: Komanda naslediya kosmicheskogo teleskopa im.Habbla (STScI/AURA), M. Donahue (STScI) i J. Trauger (JPL), NASA
Poyasnenie: Na snimke NGC 1275 vidno, kak odna galaktika "pronizyvaet" druguyu. Spiral'naya galaktika s bol'shim kolichestvom pyli "pererezaet" svoim diskom (pochti v centre izobrazheniya) bol'shuyu ellipticheskuyu galaktiku (vnizu sleva). Galaktiki pri podobnom stolknovenii mogut sil'no menyat'sya. Stalkivayushiesya galaktiki deformiruyutsya pod deistviem prilivnyh gravitacionnyh sil, oblaka gaza szhimayutsya, chto privodit k obrazovaniyu novyh oblastei zvezdoobrazovaniya. Takoe stolknovenie galaktik proishodit slishkom medlenno, prohozhdenie odnoi galaktiki cherez druguyu prodolzhaetsya poryadka 100 millionov let i nedostupno dlya nablyudenii chelovecheskim glazom. NGC 1275 vhodit v sostav skopleniya galaktik v Persee. Rasstoyanie do galaktiki - 230 millionov svetovyh let, na nebe ona raspolagaetsya v sozvezdii Perseya. Razmer kazhdoi galaktiki sostavlyaet 50 tysyach svetovyh let. Privedennyi risunok predstavlyaet soboi fotomontazh izobrazhenii, poluchennyh kosmicheskim teleskopom im.Habbla v 1995 i 2001 godah.
