Bir grup bilim adam\u0131 2011\u2019de Merk\u00fcr\u2019e g\u00f6nderilen Messenger uzay arac\u0131n\u0131n derledi\u011fi, \u00f6zellikle gezegenin d\u00f6n\u00fc\u015f h\u0131z\u0131 ve \u00e7ekim g\u00fcc\u00fc hakk\u0131ndaki verileri de\u011ferlendirerek Merk\u00fcr\u2019\u00fcn \u00e7ekirdek yap\u0131s\u0131n\u0131 ve D\u00fcnya\u2019n\u0131n \u00e7ekirde\u011fine benzerli\u011fini tespit etti.<\/p>\n
NASA, \u00f6nce bir gezenin i\u00e7 yap\u0131s\u0131na ula\u015fmadan \u00e7ekirdek yap\u0131s\u0131n\u0131n nas\u0131l tespit edilece\u011fi sorusuna cevap arad\u0131. Goddard Uzay Merkezi bilim adamlar\u0131 Samanyolu galaksisinde G\u00fcne\u015f\u2019e en yak\u0131n gezegen olan Merk\u00fcr\u2019\u00fcn d\u00f6n\u00fc\u015f hareketin tespit edilmesiyle \u00e7ekirdek yap\u0131s\u0131n\u0131n anla\u015f\u0131laca\u011f\u0131n\u0131 ortaya koydu.<\/p>\n
ABD\u2019nin do\u011fu k\u0131y\u0131s\u0131ndaki Maryland eyaleti Greebbelt\u2019de bulunan Goddard Uzay Ara\u015ft\u0131rma merkezindeki bilim adamlar\u0131n\u0131n yapt\u0131\u011f\u0131 bir \u00e7al\u0131\u015fma Merk\u00fcr\u2019\u00fcn, hemen hemen D\u00fcnya\u2019n\u0131n \u00e7ekirde\u011fine benzer olan \u00e7ekirde\u011finin i\u00e7 yap\u0131s\u0131n\u0131n kat\u0131 oldu\u011fu konusundaki tahminleri do\u011frulayan delil elde etti. NASA\u2019n\u0131n Merk\u00fcr\u2019\u00fcn daha iyi anla\u015f\u0131laca\u011f\u0131n\u0131 belirtti\u011fi ke\u015fif Co\u011frafi Ara\u015ft\u0131rma Mektuplar\u0131 (Geophysical Research Letters) ad\u0131ndaki dergide yay\u0131mland\u0131. Bu ke\u015ffin, gezegenlerin \u00e7ekirdek boyunun G\u00fcne\u015f sisteminin nas\u0131l olu\u015ftu\u011fu, kayal\u0131k gezegenlerin zamanla de\u011fi\u015fti\u011fi hakk\u0131nda bilgi verece\u011fi kaydedildi.<\/p>\n
Ara\u015ft\u0131rmay\u0131 yapan \u00e7al\u0131\u015fma grubundaki bilim adamlar\u0131ndan biri olan Antonio Genova, “Merk\u00fcr\u2019\u00fcn i\u00e7 k\u0131sm\u0131 hala aktif. \u00c7\u00fcnk\u00fc eriyik \u00e7ekirdek gezegenin zay\u0131f manyetik alan\u0131n\u0131 olu\u015fturuyor. Merk\u00fcr\u2019\u00fcn \u00e7ekirde\u011fi bizim gezegenimizden daha h\u0131zl\u0131 so\u011fudu. Bu bizim \u00e7ekirde\u011fin so\u011fumas\u0131yla manyetik alan\u0131n nas\u0131l de\u011fi\u015fece\u011fi hakk\u0131nda tahminde bulunma imkan\u0131 veriyor” dedi.<\/p>\n
MESSENGER uydusu Mart 2011\u2019de Merk\u00fcr\u2019\u00fcn y\u00f6r\u00fcngesine girdi ve 2015\u2019te gezegene \u00e7arpana kadar izleme g\u00f6revini s\u00fcrd\u00fcrd\u00fc. Ara\u015ft\u0131rmac\u0131lar G\u00fcne\u015f\u2019e en yak\u0131n gezegen olan Merk\u00fcr\u2019\u00fcn \u00e7ekirde\u011finin merkezindeki kat\u0131 kesimin 2 kilometre oldu\u011funu tespit etti. Bilim adamlar\u0131 bu bulgudan hareketle D\u00fcnya\u2019n\u0131n \u00e7ekirdek \u00e7ap\u0131n\u0131n 2 bin 400 kilometre oldu\u011funu ortaya \u00e7\u0131kard\u0131.<\/p>\n

Ancak, yak\u0131n zamana kadar G\u00fcne\u015f sisteminin k\u00fc\u00e7\u00fck gezegenin \u00e7ekirde\u011finin merkezinin kat\u0131 olabilece\u011fi hakk\u0131nda \u00e7ok az ipucu bulunuyordu.<\/p>\n","protected":false},"excerpt":{"rendered":"
