Mars’tan gelecek toprak \u00f6rnekleri; gezegenin ge\u00e7mi\u015fini ortaya \u00e7\u0131kar\u0131rken, G\u00fcne\u015f Sistemi’ndeki di\u011fer cisimlere y\u00f6nelik g\u00f6revlere de \u0131\u015f\u0131k tutacak. 2017’de NASA, Sat\u00fcrn’\u00fcn uydular\u0131 Titan ve Enceladus’ta ve J\u00fcpiter’in uydusu Europa’daki okyanuslar\u0131, ya\u015fam\u0131n bulunabilece\u011fi en olas\u0131 yerler diye nitelemi\u015fti.<\/p>\n

Uzay ajans\u0131, bu uydular\u0131n yeralt\u0131 okyanuslar\u0131n\u0131n ya\u015fama ev sahipli\u011fi yap\u0131p yapmad\u0131\u011f\u0131n\u0131 ara\u015ft\u0131rmak istiyor. Bu nedenle Perseverance’\u0131n ard\u0131ndan Titan ve Europa’y\u0131 ke\u015ffetmek i\u00e7in iki g\u00f6reve ba\u015flayacak. Europa’y\u0131 ara\u015ft\u0131racak Europa Clipper isimli uzay arac\u0131 2024’te, Titan yolcusu Dragonfly ise 2027’de f\u0131rlat\u0131lacak.<\/p>\n

Hem Perseverance hem de Dragonfly g\u00f6revinde yer alan Astrobiyolog Jorge N\u00fa\u00f1ez, “Europa ve Dragonfly gibi d\u0131\u015f gezegenlere y\u00f6nelik g\u00f6revler \u00e7ok zaman alacak” diyerek, \u015funlar\u0131 s\u00f6yledi:<\/p>\n

“Ancak ya\u015fam olanaklar\u0131 a\u00e7\u0131s\u0131ndan bulunacak her \u015feye a\u00e7\u0131k olmal\u0131y\u0131z: \u00c7evre nas\u0131l evrilir, ya\u015fam yayg\u0131n m\u0131 yoksa nadir mi? Ve d\u0131\u015far\u0131da ne var?”<\/p>\n

Mars ve y\u0131ld\u0131zlar><\/span><\/p>\n

Mars ve y\u0131ld\u0131zlar aras\u0131nda bir\u00e7ok farkl\u0131 gezegen oldu\u011fu biliniyor. Di\u011fer yandan, bilimadamlar\u0131n\u0131n en \u00e7ok ilgisini \u00e7eken karanl\u0131k madde par\u00e7ac\u0131klar\u0131. Bu karanl\u0131k madde par\u00e7ac\u0131klar\u0131n\u0131n belirli enerjilere sahip olmas\u0131 gerekti\u011fini d\u00fc\u015f\u00fcnd\u00fc\u011f\u00fcm\u00fcz i\u00e7in, karanl\u0131k madde ile a\u00e7\u0131klanabilece\u011fini s\u00f6yleniyor. Bu da bizi yeniden mars ke\u015ffine y\u00f6nlendiriyor.<\/p>\n

Bu par\u00e7ac\u0131\u011f\u0131n ne oldu\u011funa gelince, bu h\u00e2l\u00e2 b\u00fcy\u00fck bir s\u0131r. Di Mauro ve \u0130sve\u00e7\u2019teki Stockholm \u00dcniversitesi\u2019nden meslekta\u015f\u0131 Martin Wolfgang Winkler, ikinci bir \u00f6n bask\u0131 makalesinde, yak\u0131ndaki c\u00fcce k\u00fcresel galaksilerde gama \u0131\u015f\u0131n\u0131 fazlas\u0131 arayarak bu s\u0131rr\u0131 a\u00e7\u0131\u011fa \u00e7\u0131karmaya \u00e7al\u0131\u015ft\u0131lar. Onu bulamad\u0131lar ama alg\u0131lanan bu yokluk, karanl\u0131k madde par\u00e7ac\u0131\u011f\u0131n\u0131n k\u00fctlesiyle ilgili s\u0131n\u0131rlamalar olu\u015fturmalar\u0131na olanak sa\u011flad\u0131. \u0130kili, bu s\u0131n\u0131rlamalar\u0131n GCE ile uyumlu oldu\u011funun alt\u0131n\u0131 \u00e7iziyor.<\/p>\n

Yani bu durum, GCE\u2019ye karanl\u0131k maddenin sebep oldu\u011fu anlam\u0131na m\u0131 geliyor? Hay\u0131r ama buna karanl\u0131k maddenin sebep olmad\u0131\u011f\u0131n\u0131 da s\u00f6yleyemeyece\u011fimiz anlam\u0131na geliyor. Temelde, her \u015fey hi\u00e7 olmad\u0131\u011f\u0131 kadar \u015fa\u015f\u0131rt\u0131c\u0131 ve onu \u00e7\u00f6zmeye ba\u015flamak i\u00e7in fazlas\u0131yla etkileyici bilimsel ara\u015ft\u0131rmalara (ve b\u00fcy\u00fck olas\u0131l\u0131kla \u00e7ok daha fazla g\u00f6zlem yapmaya) ihtiyac\u0131m\u0131z olacak. Bir\u00e7ok fizik\u00e7inin beklenti i\u00e7inde ellerini ovu\u015fturmas\u0131 sebebiyle, g\u00fc\u00e7te b\u00fcy\u00fck bir dalgalanma hissedebiliriz.<\/p>\n
