Poyasnenie: Skol'ko pyli soderzhitsya v spiral'nyh galaktikah? Kak mnogo sveta zvezd pyl' pogloshaet ? Otvety na eti i drugie voprosy pomogut pri issledovaniyah evolyucii galaktik i kvazarov i proishozhdeniya temnogo veshestva . Na segodnyashnei kartinke , poluchennoi kosmicheskim teleskopom im. Habbla, izobrazhena pyl' vneshnih oblastei spiral'noi galaktiki (sleva) na fone osveshayushei ee ellipticheskoi galaktiki . Eta kartinka dast otvety na postavlennye voprosy. Pylevye dorozhki spiral'noi galaktiki svyazany s ee spiral'nymi rukavami. Udivitel'no , no bol'shaya chast' pylevyh oblastei ne polnost'yu pogloshaet svet i raspredelena bolee gladko, chem ozhidalos' . Eta para perekryvayushihsya galaktik oboznachaetsya AM1316-241 i nahoditsya na rasstoyanii 400 millionov svetovyh let ot nas v sozvezdii Gidra .
