NASA\u2019n\u0131n Curiosity rover adl\u0131 ke\u015fif arac\u0131, Mars\u2019ta \u015fimdiye kadar tespit edilen en \u00e7e\u015fitli organik molek\u00fcl koleksiyonlar\u0131ndan birini ortaya \u00e7\u0131kard\u0131. 2020 y\u0131l\u0131nda delinerek analiz edilen bir kaya \u00f6rne\u011finde toplam 21 karbon bazl\u0131 molek\u00fcl belirlendi ve bunlardan yedisi K\u0131z\u0131l Gezegen\u2019de ilk kez ke\u015ffedildi. Bulgular, uzun s\u00fcren laboratuvar \u00e7al\u0131\u015fmalar\u0131n\u0131n ard\u0131ndan kamuoyuyla payla\u015f\u0131ld\u0131.<\/p>\n
Bilim insanlar\u0131, bu organik molek\u00fcllerin k\u00f6keninin biyolojik mi yoksa jeolojik s\u00fcre\u00e7lere mi dayand\u0131\u011f\u0131n\u0131 hen\u00fcz netle\u015ftirebilmi\u015f de\u011fil. Ancak her iki ihtimal de m\u00fcmk\u00fcn g\u00f6r\u00fcl\u00fcyor. Ara\u015ft\u0131rmac\u0131lara g\u00f6re bu ke\u015fif, Mars\u2019\u0131n ge\u00e7mi\u015fte ya\u015fam\u0131 destekleyebilecek kimyasal ko\u015fullara sahip oldu\u011funu bir kez daha g\u00fc\u00e7lendiriyor. Ayr\u0131ca bu bile\u015fiklerin, milyarlarca y\u0131l boyunca yo\u011fun radyasyona ra\u011fmen kayalarda korunabilmi\u015f olmas\u0131 dikkat \u00e7ekiyor.<\/p>\n

Bu \u00f6rnek, Mars\u2019\u0131n ge\u00e7mi\u015fte g\u00f6ller ve akarsularla kapl\u0131 oldu\u011fu d\u00fc\u015f\u00fcn\u00fclen Mount Sharp b\u00f6lgesinden topland\u0131. B\u00f6lgenin zamanla kuruyup yeniden suyla doldu\u011fu ve bu s\u00fcre\u00e7te kil mineralleri a\u00e7\u0131s\u0131ndan zenginle\u015fti\u011fi ifade ediliyor.<\/p>\n
Yeni ke\u015ffedilen molek\u00fcller aras\u0131nda, azot i\u00e7eren halka yap\u0131s\u0131na sahip bir azot heterosikl\u00fc de bulunuyor. Bu t\u00fcr yap\u0131lar, genetik bilginin temel ta\u015f\u0131 olan DNA ve RNA gibi molek\u00fcllerin \u00f6nc\u00fcs\u00fc olarak kabul ediliyor. Ara\u015ft\u0131rman\u0131n ba\u015f yazar\u0131 Amy Williams, bu bulgunun \u00f6nemine dikkat \u00e7ekerek, s\u00f6z konusu yap\u0131lar\u0131n daha karma\u015f\u0131k organik kimyan\u0131n temelini olu\u015fturabilece\u011fini belirtti.<\/p>\n","protected":false},"excerpt":{"rendered":"
