\u00c7\u0131\u011f\u0131r a\u00e7an bir astronomik harikas\u0131 olan James Webb Uzay Teleskobu (JWST), ilk nefes kesici y\u0131ld\u0131z \u0131\u015f\u0131\u011f\u0131 g\u00f6r\u00fcnt\u00fclerini yakalad\u0131. 18 alt\u0131n aynas\u0131n\u0131 ba\u015far\u0131yla a\u00e7t\u0131ktan sonra teleskop, kozmosa “g\u00f6zlerini” a\u00e7t\u0131.<\/p>\n\n
JWST’nin yakalad\u0131\u011f\u0131 ilk g\u00f6r\u00fcnt\u00fcler, tamamen \u00e7al\u0131\u015f\u0131r hale geldi\u011finde sunaca\u011f\u0131 “evrenin benzeri g\u00f6r\u00fclmemi\u015f manzaralar\u0131ndan” \u00e7ok uzakta. \u015eimdilik, teleskobun her bir aynas\u0131 ba\u011f\u0131ms\u0131z bir teleskop olarak hareket ediyor ve bu da 260 \u0131\u015f\u0131k y\u0131l\u0131 uzakl\u0131ktaki ayn\u0131 y\u0131ld\u0131z olan HD-84406’n\u0131n 18 bulan\u0131k g\u00f6r\u00fcnt\u00fcs\u00fcne yol a\u00e7\u0131yor.<\/p>\n\n
Bulan\u0131k g\u00f6r\u00fcnt\u00fcler, JWST’nin Yak\u0131n K\u0131z\u0131l\u00f6tesi Kamera’s\u0131n\u0131n (NIRcam) yeteneklerini sergileyen, iki milyar\u0131n \u00fczerinde piksele sahip devasa bir mozaik olu\u015fturmak i\u00e7in birle\u015ftirildi. NIRcam, daha y\u00fcksek s\u0131cakl\u0131klarda \u00e7al\u0131\u015f\u0131r ve bu da teleskobun kriyojenik \u00e7al\u0131\u015fma s\u0131cakl\u0131klar\u0131na tamamen so\u011fumas\u0131ndan \u00f6nce \u00e7al\u0131\u015fmas\u0131na olanak tan\u0131r.<\/p>\n\n
G\u00f6kbilimciler \u015fimdi teleskobun aynalar\u0131n\u0131 hizalama gibi hassas bir g\u00f6reve giri\u015ftiler. \u00d6n\u00fcm\u00fczdeki birka\u00e7 ay boyunca, 18 bulan\u0131k g\u00f6r\u00fcnt\u00fc tek bir odaklanm\u0131\u015f y\u0131ld\u0131zda birle\u015fene kadar her aynay\u0131 titizlikle ayarlayacaklar.<\/p>\n\n
HD-84406, JWST’nin ilk g\u00f6zlemleri i\u00e7in kolayca tan\u0131mlanabilir yap\u0131s\u0131 ve kafa kar\u0131\u015f\u0131kl\u0131\u011f\u0131na neden olabilecek yak\u0131ndaki y\u0131ld\u0131zlar\u0131n olmamas\u0131 nedeniyle dikkatlice hedef y\u0131ld\u0131z olarak se\u00e7ildi.<\/p>\n\n
NIRcam, JWST’nin erken g\u00f6zlemlerinde \u00e7ok \u00f6nemli bir rol oynuyor. K\u0131z\u0131l\u00f6tesi \u0131\u015f\u0131\u011f\u0131 tespit eder ve bu da \u0131s\u0131 olarak kaydedilir ve teleskobun optimum so\u011futma s\u0131cakl\u0131klar\u0131na ula\u015fmadan \u00f6nce \u00e7al\u0131\u015fmas\u0131na olanak tan\u0131r.<\/p>\n\n
