Obshaya teoriya otnositel'nosti
Al'berta Einshteina,
opublikovannaya 100 let nazad v etom mesyace, predskazyvala yavlenie gravitacionnogo linzirovaniya.
Eto yavlenie daet pokazannym zdes' dalekim galaktikam takoi prichudlivyi vid.
Izobrazhenie
ob'edinyaet dannye v rentgenovskom i opticheskom diapazonah, poluchennye kosmicheskimi teleskopami
"Chandra" i "Habbl".
Eti galaktiki poluchili nazvanie gruppa galaktik Cheshirskii kot.
Dve bol'shie ellipticheskie galaktiki obramleny dugami.
Dugi – eto opticheskie izobrazheniya galaktik dalekogo fona,
podvergshiesya linzirovaniyu gravitacionnym polem bolee blizkoi gruppy galaktik, v
sozdanii kotorogo dominiruet temnaya materiya.
Dve bol'shie ellipticheskie galaktiki – "glaza" – yavlyayutsya yarchaishimi
galaktikami svoih sobstvennyh grupp, kotorye slivayutsya.
Otnositel'naya skorost' stolknoveniya – pochti 1350 kilometrov v sekundu,
ona nagrevaet gaz do neskol'kih millionov gradusov i on izluchaet rentgenovskie luchi,
pokazannye fioletovym cvetom.
Interesuetes'
slivayushimisya gruppami galaktik?
Gruppa
Cheshirskii kot uhmylyaetsya v sozvezdii Bol'shoi Medvedicy, na rasstoyanii v 4.6 milliardov
svetovyh let.
