Bilim insanlar\u0131, ABD Havac\u0131l\u0131k ve Uzay Ajans\u0131n\u0131n (NASA<\/a>) James Webb Uzay Teleskobu (JWST) verilerini inceleyerek “kozmik \u00f6\u011fle vakti” de denen ve \u00e7ok say\u0131da y\u0131ld\u0131z\u0131n olu\u015ftu\u011fu d\u00f6neme ait 44 yeni y\u0131ld\u0131z ke\u015ffetti.<\/p>\n

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

Sun, “Bu heyecan verici bir bulu\u015ftu \u00e7\u00fcnk\u00fc bu kadar uzaktaki b\u00f6ylesine \u00e7ok y\u0131ld\u0131z\u0131 ilk kez g\u00f6rebildik.” dedi.<\/p>\n

Ara\u015ft\u0131rmac\u0131lar, uzak galaksideki 44 yeni y\u0131ld\u0131z\u0131, JWST’nin hassas kameralar\u0131yla g\u00f6k cisimlerinin “k\u00fctle \u00e7ekimsel mercekleme” etkisinden faydalanarak tespit etti.<\/p>\n

B\u00fcy\u00fck k\u00fctleli g\u00f6kcisimlerinin yo\u011fun k\u00fctle \u00e7ekim alanlar\u0131n\u0131n tetikledi\u011fi do\u011fal bir b\u00fcy\u00fctme etkisi olan “k\u00fctle \u00e7ekimsel mercekleme”, g\u00f6k cisimlerinin arkas\u0131nda kalan y\u0131ld\u0131zlar\u0131n ve galaksilerin g\u00f6r\u00fcnt\u00fclenmesini sa\u011fl\u0131yor.<\/p>\n

Bu sayede, uzaktaki y\u0131ld\u0131zlar\u0131n \u0131\u015f\u0131klar\u0131 y\u00fczlerce hatta binlerce defa b\u00fcy\u00fcyerek JWST gibi hassas teleskoplar taraf\u0131ndan tespit edilebiliyor.<\/p>\n

BUG\u00dcNE KADAR EN FAZLA SAYIDAK\u0130 YILDIZ\u00a0<\/strong><\/p>\n

Ara\u015ft\u0131rma, evrenin derinliklerinde bug\u00fcne kadar bulunan en fazla say\u0131daki y\u0131ld\u0131z\u0131n ke\u015ffiyle ba\u015fl\u0131 ba\u015f\u0131na bir rekor k\u0131rd\u0131.<\/p>\n

\u00d6te yandan BBC’nin haberine g\u00f6re, ara\u015ft\u0131rmaya kat\u0131lan Durham \u00dcniversitesinden bilim insanlar\u0131, s\u00f6z konusu 44 yeni y\u0131ld\u0131z\u0131n, 4 milyar \u0131\u015f\u0131k y\u0131l\u0131 uzakl\u0131ktaki “Abell 370” ad\u0131 verilen bir g\u00f6kada k\u00fcmesinin arkas\u0131nda bulunan “Dragon Arc” galaksisine ait oldu\u011funu kaydetti.<\/p>\n

KIRMIZI S\u00dcPER DEVLER VAR\u00a0<\/strong><\/p>\n

Durham \u00dcniversitesi \u00d6\u011fretim \u00dcyesi Prof. Dr. Mathilde Jauzac, “kozmik \u00f6\u011fle vaktinin” evrendeki y\u0131ld\u0131z olu\u015fumlar\u0131n\u0131n en fazla oldu\u011fu zaman dilimi oldu\u011funu ancak bu g\u00f6k cisimlerini g\u00f6zlemlemenin zor oldu\u011funu belirtti.<\/p>\n

Jauzac, “Dragon Arc’ta tespit etti\u011fimiz bu \u00e7ok \u00f6zel y\u0131ld\u0131z t\u00fcr\u00fc, “k\u0131rm\u0131z\u0131 s\u00fcper dev” olarak adland\u0131r\u0131l\u0131yor ve g\u00f6zlemlenmeleri \u00e7ok zor. Bunlar\u0131n \u00e7evresinde \u00e7ok fazla toz bulunuyor ve bu toz onlar\u0131 standart aletler i\u00e7in g\u00f6r\u00fcnmez k\u0131l\u0131yor.” ifadesini kulland\u0131.<\/p>\n
