Poyasnenie: Mozhet li gravitaciya izobrazhennyh na fotografii galaktik uderzhat' soderzhashiisya v toi oblasti svetyashiisya goryachii gaz? Kartinka yavlyaetsya nalozheniem opticheskogo i rentgenovskogo izobrazhenii. Na poluchennom s pomosh'yu Orbital'noi Rentgenovskoi Observatorii rentgenovskom snimke, pokazana v uslovnyh cvetah ogranichennaya oblast' svetyashegosya gaza. Eti nablyudeniya svidetel'stvuyut o tom, chto gravitaciya grupp i skoplenii galaktik prevyshaet potencial, obuslovlennyi summarnoi gravitaciei otdel'nyh sostavlyayushih. Etot fakt ob'yasnyaetsya prisutstviem temnoi materii, priroda i kolichestvo kotoroi ostaetsya ogromnoi zagadkoi v astronomii i po sei den'.
