Evrende yaln\u0131z olmad\u0131\u011f\u0131m\u0131z kan\u0131t\u0131 bir haber ortaya \u00e7\u0131kt\u0131. D\u00fcnyam\u0131za benzer yeni bir gezegen ortaya \u00e7\u0131kt\u0131. Evrende d\u00fcnyam\u0131z d\u0131\u015f\u0131nda \u00e7ok say\u0131da gezegen ve c\u00fcce gezegen bulunuyor. G\u00fcne\u015f sistemi bunun sadece bir par\u00e7as\u0131. D\u00fcnyam\u0131z\u0131n yer ald\u0131\u011f\u0131 g\u00fcne\u015f sistemi d\u0131\u015f\u0131nda da bug\u00fcne kadar 2000’i a\u015fk\u0131n gezegen ke\u015ffedildi.
\nKe\u015ffedilen gezegen \u00e7e\u015fitlerinden biri de dev d\u00fcnyalar. Astronomide, d\u00fcnyan\u0131n k\u00fctlesinden b\u00fcy\u00fck, fakat gaz devinden daha k\u00fc\u00e7\u00fck olarak tan\u0131mlanan bu gezegenlerin fiziksel \u00f6zellikleri asl\u0131nda d\u00fcnya ile hi\u00e7bir benzerlik g\u00f6stermiyor. Dev d\u00fcnya olarak an\u0131lmas\u0131n\u0131n tek sebebi, boyut anlam\u0131nda d\u00fcnyaya yak\u0131n olmas\u0131.<\/p>\n

Avrupa Uzay Ajans\u0131 (ESA) ve Londra \u00dcniversitesi ile koordineli \u00e7al\u0131\u015fan NASA astronomlar\u0131, ge\u00e7ti\u011fimiz g\u00fcn ilk kez atmosferi bulunan bir dev d\u00fcnya bulduklar\u0131n\u0131 duyurdu.
\nHubble uzay teleskobunun geni\u015f alan kameras\u0131yla ilk olarak 2004 y\u0131l\u0131nda ke\u015ffedilen 55 Cancri e isimli gezegen, d\u00fcnyadan 8 kat b\u00fcy\u00fck ve 40 \u0131\u015f\u0131k y\u0131l\u0131 uzakl\u0131kta bulunuyor.
\nAstronomlara 55 Cancri e’nin y\u00fczeyinde atmosfer bulunmas\u0131, dev d\u00fcnyalar\u0131 anlama hususunda olduk\u00e7a \u00f6nemli bir olay. Londra \u00dcniversitesi ara\u015ft\u0131rmac\u0131lar\u0131ndan Angelos Tsiaras, 55 Cancri e’de atmosferin g\u00f6zlemlenmesi, dev d\u00fcnyan\u0131n ciddi oranda hidrojen ve helyum bar\u0131nd\u0131rd\u0131\u011f\u0131n\u0131 belirtti.<\/p>\n

Gezegenin \u00e7evresinde atmosferin bulunmas\u0131 ak\u0131llara ilk olarak ya\u015fam\u0131n olabilece\u011fi d\u00fc\u015f\u00fcncesini getiriyor ancak 55 Cancri e’de \u00e7ok b\u00fcy\u00fck ihtimalle ya\u015fam yok. Bunun en b\u00fcy\u00fck nedeni \u015f\u00fcphesiz atmosferinde sadece hidrojen ve helyum olmas\u0131 ve su izine hi\u00e7 rastlanmamas\u0131. Ayr\u0131ca dev d\u00fcnyan\u0131n y\u00fczeyinin yakla\u015f\u0131k 2.000 derece s\u0131cakl\u0131\u011f\u0131nda oldu\u011fu tahmin ediliyor.
\nHepsi bir yana 55 Cancri e d\u00fcnyaya tam 40 \u0131\u015f\u0131k y\u0131l\u0131 uzakl\u0131\u011f\u0131nda bulunuyor. 1 \u0131\u015f\u0131k y\u0131l\u0131n\u0131n 9.460.800.000.000 km oldu\u011funu d\u00fc\u015f\u00fcn\u00fcrsek, dev d\u00fcnya ne kadar uzak oldu\u011funu ve oraya eri\u015fmenin neredeyse imkans\u0131z oldu\u011funu anlayabiliriz.<\/p>\n","protected":false},"excerpt":{"rendered":"
