Uluslararas\u0131 g\u00f6kbilimciler ekibi, NASA\u2019n\u0131n Hubble uzay teleskobunu kullanarak y\u0131ld\u0131z yapan kom\u015fu galaksilerin mor \u00f6tesi \u0131\u015f\u0131kla taranmas\u0131ndan elde edilen en net, y\u00fcksek \u00e7\u00f6z\u00fcn\u00fcrl\u00fckte ve kapsaml\u0131 g\u00f6r\u00fcnt\u00fclerini yay\u0131mlad\u0131.<\/p>\n
Ekip, Hubble teleskobunun yeni g\u00f6zlemleri ile, mahalli evrende y\u0131ld\u0131z yapan 50 spiral ve c\u00fcce galaksinin ar\u015fiv g\u00f6r\u00fcnt\u00fclerini birle\u015ftirdi. Bu alt\u0131 g\u00f6r\u00fcnt\u00fc kom\u015fu galaksilerdeki y\u0131ld\u0131z yapan b\u00f6lgelerin \u00e7e\u015fitlili\u011fini temsil ediyor. Bu alt\u0131 g\u00f6r\u00fcnt\u00fc iki c\u00fcce galaksi ve d\u00f6rt b\u00fcy\u00fck spiral galaksiden olu\u015fuyor.<\/p>\n
G\u00f6r\u00fcnt\u00fcler, Hubble\u2019in geni\u015f alan 3 kameras\u0131 ve geli\u015fmi\u015f kameralar\u0131 taraf\u0131ndan mor\u00f6tesi ve g\u00f6r\u00fclebilir \u0131\u015f\u0131klarla elde edilen g\u00f6r\u00fcnt\u00fclerin karmas\u0131.<\/p>\n
Ekstra Galaktik Mor\u00f6tesi tarama miras\u0131 (Legacy ExtraGalactic UV Survey) (LEGUS) isimli bu proje, galaksilerin kendi g\u00f6r\u00fcnt\u00fclerinin yan\u0131nda LEGUS galaksilerinin her biri ve galaksilerinin 30\u2019unun salk\u0131m katalo\u011funu bir araya toplad\u0131.<\/p>\n
Bireysel y\u0131ld\u0131z salk\u0131mlar\u0131ndaki her bir y\u0131ld\u0131z\u0131 bu d\u00fczendeki yap\u0131lara ba\u011flama konusunda birbiriyle yar\u0131\u015fan \u00e7ok say\u0131da teori bulundu\u011fu ifade edildi.<\/p>\n
G\u00f6k bilimcililer: “Daha b\u00fcy\u00fck yap\u0131larla ba\u011flant\u0131s\u0131n\u0131 da g\u00f6stererek Galaksilerin i\u00e7lerindeki y\u0131ld\u0131z salk\u0131mlar\u0131n\u0131n say\u0131s\u0131n\u0131 ve fiziki parametrelerini tan\u0131mlamaya \u00e7al\u0131\u015f\u0131yoruz.
