Gigantskaya krasivaya galaktika
Andromedy (M31) nahoditsya na rasstoyanii dvuh
millionov svetovyh let ot nas i schitaetsya analogom nashei Galaktiki, t.e.
zerkalom togo, chto proishodit u nas.
V populyarnom proizvedenii nauchnoi fantastiki 1960-h godov
"A dlya
Andromedy" opisyvalas' tehnologichnaya civilizaciya, kotoraya nahodilas' v
obshenii s
lyud'mi. Pisateli i chitateli
nauchnoi fantastiki 60-h godov by byli ochen' voodushevleny otkrytiyami
nastoyashego vremeni. Tak,
astronomy s pomosh'yu moshnogo rentgenovskogo teleskopa
Chandra sdelali izobrazhenie centra sosednei k nam
galaktiki i otkryli udivitel'nye ob'ekty.
Takzhe kak i v nashei Galaktike v centre galaktiki
Andromedy nahoditsya rentgenovskii istochnik, kotoryi associiruetsya s
chernoi dyroi massoi million ili bol'she mass Solnca.
Na kartinke pokazano
rentgenovskoe izobrazhenie v uslovnyh cvetah, na kotorom otchetlivo vidny
mnozhestvo rentgenovskih istochnikov v vide zheltyh pyaten. Skoree vsego, eto
rentgenovskie dvoinye zvezdy, kotorye nahodyatsya v central'noi oblasti
galaktiki Andromedy. Goluboe pyatno ukazyvaet na polozhenie chernoi
dyry.
Rentgenovskie luchi izluchaet veshestvo, kotoroe padaet na chernuyu dyru i
nagrevaetsya v processe padeniya. Ocenki, sdelannye na osnove rentgenovskih
nablyudenii, pokazyvayut, chto central'nyi ob'ekt udivitel'no holodnyi - tol'ko
million gradusov! Sravnite eto znachenie s desyatkami millionov gradusov -
temperaturoi rentgenovskih dvoinyh zvezd v galaktike Andromedy.
