Poyasnenie: 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.
