Poyasnenie:
V 1990-h godah sputnik po issledovaniyu kosmicheskogo fona
(COsmic Background Explorer - COBE)
otskaniroval vse nebo v infrakrasnom svete. Kartinka, kotoruyu Vy
vidite, yavlyaetsya rezul'tatom issledovaniya central'noi oblasti Mlechnogo
Puti. Mlechnyi Put' - obychnaya spiral'naya galaktika, u kotoroi
est' central'nyi baldzh i protyazhennyi zvezdnyi disk. Gaz i pyl'
v diske pogloshayut izluchenie v vidimom diapazone, chto meshaet
nablyudeniyam centra galaktiki. Tak kak infrakrasnyi svet slabee
pogloshaetsya gazom i pyl'yu, to eksperiment po izucheniyu diffuznogo
infrakrasnogo fona
(Diffuse InfraRed Background Experiment - DIRBE)
na bortu sputnika COBE po issledovaniyu
kosmicheskogo fona registriruet eto izluchenie ot zvezd, okruzhayushih
galakticheskii centr. Privedennoe vyshe izobrazhenie predstavlyaet soboi
vid galakticheskogo centra s rasstoyaniya 30000 svetovyh let (eto
rasstoyanie ot Solnca do centra nashei galaktiki). V eksperimente
DIBRE ispol'zuetsya apparatura,
ohlazhdaemaya zhidkim geliem, special'no dlya registracii infrakrasnogo
izlucheniya, k kotoromu chelovecheskii glaz nechuvstvitelen.
