Poyasnenie: V sozvezdii Zmei v 7000 svetovyh let ot nas v zvezdnoi kolybeli, nosyashei nazvanie tumannost' Orel ili M16, pryamo seichas rozhdayutsya zvezdy. Peresekayushie tumannost' gazopylevye stolby, v kotoryh idet obrazovanie zvezd znakomy astronomam v opticheskom diapazone, no eto izobrazhenie v iskusstvennyh cvetah demonstriruet tumannost' v infrakrasnyh luchah. Dlya postroeniya etogo podrobnogo dvuhcvetnogo izobrazheniya, na kotorom preobladaet izluchenie oblakov mezhzvezdnogo veshestva s temperaturoi nizhe –100 gradusov Cel'siya, ispol'zovalis' dannye Infrakrasnoi kosmicheskoi observatorii, (ISO), prinadlezhashei Evropeiskomu kosmicheskomu agntstvu (EKA). Goluboi cvet svidetel'stvuet o prisutstvii slozhnyh uglevodorodnyh molekul, nazyvaemyh na Zemle aromaticheskimi. V to zhe vremya krasnyi cvet sootvetstvuet holodnym mikroskopicheskim pylevym granulam. Goryachie molodye zvezdy obrazuyutsya v hode uplotneniya etogo holodnogo veshestva pod deistviem gravitacii. Odnazhdy nachavshis' process zanimaet vsego neskol'ko desyatkov tysyach let dlya ochen' massivnyh zvezd i rastyagivaetsya na desyatki millionov dlya zvezd maloi massy, podobnyh Solncu.
