Ortaya \u00e7\u0131kan “korkun\u00e7” g\u00f6rsel, milyonlarca y\u0131l \u00f6nce birbirine \u00e7ok yak\u0131n, neredeyse “s\u00fcrt\u00fcnerek” ge\u00e7en iki b\u00fcy\u00fck sarmal galaksinin g\u00f6r\u00fcnt\u00fcs\u00fcn\u00fc yans\u0131t\u0131yor.<\/p>\n

Bilim insanlar\u0131, galaksilerdeki maddelerin birbirine \u00e7arpm\u0131\u015f olabilece\u011fi \u015fok cephelerinde ya\u015fanan “hafif s\u0131yr\u0131klar\u0131n” kan\u0131tlar\u0131n\u0131 buldu.<\/p>\n
“G\u00f6z kapaklar\u0131nda” da g\u00f6r\u00fclebilen parlak k\u0131rm\u0131z\u0131 \u00e7izgiler, galaksilerin \u015fi\u015fkin, damarl\u0131 kollar\u0131 gibi g\u00f6r\u00fcn\u00fcyor.<\/p>\n
Galaksilerin ilk yak\u0131n ge\u00e7i\u015finde, k\u00fctle \u00e7ekiminin kavisli kollar\u0131 b\u00fckt\u00fc\u011f\u00fc ve birka\u00e7 yerde de gelgit benzeri uzant\u0131lar\u0131n olu\u015ftu\u011fu tespit edildi.<\/p>\n

Ara\u015ft\u0131rmac\u0131lar, g\u00f6rselin solunda yer alan IC 2163’\u00fcn \u00e7ekirde\u011fi ile en soldaki kolu aras\u0131ndaki da\u011f\u0131n\u0131k, minik sarmal kollar\u0131n k\u00fctle \u00e7ekimi etkisiyle meydana geldi\u011fini ke\u015ffetti.<\/p>\n
K\u00fctle \u00e7ekimiyle, biraz daha b\u00fcy\u00fck olan NGC 2207 galaksisinin tepesinden “s\u00fcr\u00fckleniyor” gibi g\u00f6r\u00fcnen ve g\u00f6rselin d\u0131\u015f\u0131na do\u011fru uzanan ince, yar\u0131 saydam bir kol olu\u015ftu.<\/p>\n
Bilim insanlar\u0131, her iki galaksiden uzanan “kollar\u0131n” her yerinde say\u0131s\u0131z “kalp gibi atan” y\u00fcksek y\u0131ld\u0131z olu\u015fum b\u00f6lgeleri tespit etti.<\/p>\n
