Poyasnenie: Pochemu vo mnogih galaktikah chetko proslezhivaetsya spiral'naya struktura? Yarkim primerom spiral'noi galaktiki yavlyaetsya M101 (sm. risunok). Sravnitel'no nebol'shoe rasstoyanie do etoi galaktiki, 22 milliona svetovyh let, pozvolyaet detal'no ee izuchit'. Poslednie dannye svidetel'stvuyut o tom, chto v rezul'tate tesnogo gravitacionnogo vzaimodeistviya s sosednei galaktikoi vokrug M101 obrazovalis' volny szhatiya, i vokrug centra galaktiki vrashaetsya szhatyi gaz. Szhatie gaza pod deistviem etih voln privelo k nachalu processa zvezdoobrazovaniya. V spiral'nyh rukavah galaktiki M101, nazyvaemoi takzhe Bulavochnoe Koleso (Pinwheel Galaxy), imeyutsya neskol'ko chrezvychaino yarkih oblastei zvezdoobrazovaniya (oblastei HII). M101 - gigantskaya galaktika, i sosednie nebol'shie galaktiki ispytyvayut na sebe deistvie ee gravitacionnogo polya.
