J\u00fcpiter’in birka\u00e7 kat\u0131 k\u00fctleye sahip olan gezegen, G\u00fcne\u015f’in ya\u015f\u0131 civar\u0131nda, ancak biraz daha so\u011fuk olan K-tipi y\u0131ld\u0131z Epsilon Indi A<\/strong>‘n\u0131n y\u00f6r\u00fcngesinde d\u00f6n\u00fcyor.

Bilim insanlar\u0131 bu ke\u015ffin heyecan verici oldu\u011funu \u00e7\u00fcnk\u00fc gezegen J\u00fcpiter’e olduk\u00e7a<\/strong> benziyor<\/strong>, sadece biraz daha s\u0131cak ve daha b\u00fcy\u00fck. Daha \u00f6nce g\u00f6r\u00fcnt\u00fclenen \u00f6tegezegenler, ilk olu\u015ftuklar\u0131 zamanki enerjinin \u00e7o\u011funu hala yaymakta olan gen\u00e7 ve s\u0131cak gezegenler olma e\u011filiminde. Zira gezegenler ya\u015fland\u0131k\u00e7a so\u011fuyor ve daha s\u00f6n\u00fck hale geliyor. Bu da g\u00f6r\u00fcnt\u00fclenmelerini zorla\u015ft\u0131r\u0131yor.<\/p>\n

<\/span> NASA, Epsilon Indi Ab\u2019nin sadece 2 santigrat derece<\/strong> s\u0131cakl\u0131\u011f\u0131yla do\u011frudan tespit edilen en so\u011fuk \u00f6tegezegenlerden birisi oldu\u011funun alt\u0131n\u0131 \u00e7iziyor.

Epsilon Indi Ab, bug\u00fcne kadar bilinen D\u00fcnya’ya en yak\u0131n on ikinci d\u0131\u015f gezegen ve J\u00fcpiter’den daha b\u00fcy\u00fck olan en yak\u0131n gezegen konumunda. Bununla birlikte gezegenin daha \u00f6nce tahmin edilenlerle uyu\u015fmad\u0131\u011f\u0131 da belirtiliyor. Zira gezegenin tahminlerden iki kat daha b\u00fcy\u00fck oldu\u011fu ve farkl\u0131 bir y\u00f6r\u00fcngede dola\u015ft\u0131\u011f\u0131 belirtiliyor. Gezegenin atmosferi de model tahminlerinden biraz farkl\u0131 g\u00f6r\u00fcn\u00fcyor. Bilim insanlar\u0131 bu tutars\u0131zl\u0131klar\u0131n nedenini \u015fimdilik bilmiyor.<\/p>\n

Bilim insanlar\u0131 JWST ile takip g\u00f6zlemleri yapmay\u0131 planl\u0131yor. \u00d6te yandan NASA’n\u0131n yakla\u015fmakta olan Nancy Grace Roman Uzay Teleskobu, G\u00fcne\u015f benzeri y\u0131ld\u0131zlar\u0131n y\u00f6r\u00fcngesindeki J\u00fcpiter benzeri gezegenleri do\u011frudan g\u00f6r\u00fcnt\u00fcleyebilecek bir koronagraf kullanacak. Nancy Grace Roman ile JWST\u2019nin eksik oldu\u011fu alanlar doldurulacak.<\/p>\n\n
