Poyasnenie:
Issledovanie kvazarov i
aktivnyh galaktik na okrainah Vselennoi
pozvolili astronomam vydvinut' gipotezu, chto bol'shinstvo galaktik soderzhat v
centrah massivnye chernye dyry.
Zvezdy, dvizhushiesya po spiralyam, i moshnoe peremennoe
radioizluchenie predpolagayut nalichie dazhe v
centre nashei Galaktiki, t.e. na rasstoyanii okolo
30 tysyach svetovyh let, pohozhego
udivitel'nogo ob'ekta
Esli massivnaya chernaya dyra deistvitel'no
skryvaetsya tam, to centr Galaktiki dolzhen byt' istochnikom
rentgenovskih luchei, kotorye ranee ne byli
otkryty. Teper' zhe otsutstvuyushie ranee rentgenovskie luchi byli obnaruzheny!
Blagodarya vysokochuvstvitel'noi observatorii Chandra
astronomy sozdali eto
rentgenovskoe izobrazhenie galakticheskogo centra v uslovnyh cvetah.
V centre razmytogo oblaka
gaza, goryachego v rentgenovskom svete,
vkrapleno beloe pyatno - rentgenovskii istochnik, kotoryi raspolozhen tochno v
meste moshnogo radioistochnika i, skoree vsego, yavlyaetsya chernoi dyroi.
Drugie otdel'nye rentgenovskie istochniki, kotorye vidny na izobrazhenii,
imeyut protyazhennost' okolo 10-ti svetovyh let i nahodyatsya gde-to v raione
galakticheskogo centra. Sudya po svetimosti v radio- i rentgenovskom
diapazonah, kotoruyu sozdaet padayushee na central'nuyu chernuyu dyru veshestvo,
massa ee ocenivaetsya v dva milliona mass Solnca.
