Poyasnenie: Hotya NGC 4945 - ochen' blizkaya galaktika, ee legko mozhno ne zametit'. NGC 4945 - eto spiral'naya galaktika v gruppe galaktik Centavra. Ona nahoditsya vsego v shest' raz dal'she, chem horosho vidimaya galaktika Andromedy. Odnako eta tonkaya diskoobraznaya galaktika vidna pochti s rebra i pogruzhena v temnuyu pyl'. Poetomu nablyudateli galaktik, issleduyushie yuzhnoe sozvezdie Centavra, mogut uvidet' ee tol'ko v teleskop. Eto izobrazhenie bylo polucheno na bol'shom teleskope vo vremya ispytanii novoi PZS-kamery s vysokim razresheniem i bol'shim polem zreniya. Bol'shaya chast' pyatnyshek, razbrosannyh po izobrazheniyu - eto zvezdy fona, prinadlezhashie nashei Galaktike, no nekotorye - eto sharovye skopleniya, obrashayushiesya vokrug dalekoi galaktiki. Predpolagayut, chto NGC 4945 dostatochno pohozha na nashu Galaktiku Mlechnyi Put'. Odnako rentgenovskie nablyudeniya pokazali, chto u NGC 4945 neobychnoe aktivnoe yadro tipa Seifert 2, v kotorom mozhet nahodit'sya gigantskaya chernaya dyra.
