Harvard-Smithsonian Astrofizik Merkezinden Fengwu Sun liderli\u011findeki bilim insanlar\u0131, D\u00fcnya\u2019ya 6,5 milyar y\u0131l uzakl\u0131ktaki \u201cDragon Arc\u201d ad\u0131 verilen bir galaksinin, evrenin yar\u0131 ya\u015f\u0131nda oldu\u011fu d\u00f6neme ait g\u00f6r\u00fcnt\u00fclerini inceledi.<\/p>\n
