NASA, 3I\/ATLAS <\/strong>ad\u0131 verilen sistemimize giren \u00fc\u00e7\u00fcnc\u00fc do\u011frulanm\u0131\u015f y\u0131ld\u0131zlararas\u0131 g\u00f6\u00e7meni detayl\u0131 bir \u015fekilde g\u00f6zler \u00f6n\u00fcne serdi. Ekim ay\u0131nda Mars yak\u0131n\u0131ndan h\u0131zla ge\u00e7en kuyruklu y\u0131ld\u0131z, MAVEN, Mars Reconnaissance Orbiter (MRO) ve Perseverance taraf\u0131ndan izlenerek bilim insanlar\u0131na, ba\u015fka bir y\u0131ld\u0131z sisteminden gelen nadir bir nesnenin kimyas\u0131 hakk\u0131nda e\u015fsiz veriler sa\u011flad\u0131. Uzaydan al\u0131nan bu g\u00f6zlemler, D\u00fcnya\u2019dan elde edilemeyecek bilgiler i\u00e7eriyor. Kuyruklu y\u0131ld\u0131z\u0131n 440 metre ile 5.6 kilometre<\/strong> aras\u0131nda bir \u00e7apa sahip oldu\u011fu de\u011ferlendiriliyor.\u00a0<\/p>\n

G\u00f6zlemler kritik veriler sa\u011flad\u0131<\/b><\/p>\n

Mars y\u00f6r\u00fcngesindeki uzay ara\u00e7lar\u0131, kuyruklu y\u0131ld\u0131z\u0131 yak\u0131n mesafeden takip etti. MRO\u2019nun HiRISE kameras\u0131, Mars y\u00fczeyini b\u0131rak\u0131p h\u0131zla hareket eden hedefe kilitlendi. Kuyruklu y\u0131ld\u0131z, uzay arac\u0131ndan yakla\u015f\u0131k 31 milyon kilometre uzakl\u0131ktan ge\u00e7ti ve HiRISE, toz ve buzdan olu\u015fan parlak, pikselle\u015fmi\u015f bir k\u00fcre kaydetti. Ara\u015ft\u0131rmac\u0131lar, \u015fimdi bu g\u00f6r\u00fcnt\u00fcleri inceleyerek \u00e7ekirdek boyutunu, koma i\u00e7indeki par\u00e7ac\u0131klar\u0131n \u015fekil ve rengini belirlemeye \u00e7al\u0131\u015f\u0131yor.<\/p>\n

NASA\u2019n\u0131n MAVEN uzay arac\u0131 da kuyruklu y\u0131ld\u0131z\u0131 10 g\u00fcn boyunca takip etti. MAVEN\u2019in ultraviyole spektrograf\u0131, birden fazla dalga boyunda \u00f6l\u00e7\u00fcmler alarak komadaki hidrojenin y\u00fcksek \u00e7\u00f6z\u00fcn\u00fcrl\u00fckl\u00fc g\u00f6r\u00fcnt\u00fclerini \u00fcretti. Bu veriler, bilim insanlar\u0131n\u0131n kuyruklu y\u0131ld\u0131z\u0131n bile\u015fimini ve su buhar\u0131 sal\u0131m h\u0131z\u0131n\u0131 incelemesine olanak tan\u0131yor.<\/p>\n

MAVEN verileri ayr\u0131ca kuyruklu y\u0131ld\u0131z\u0131n d\u00f6teryum\/hidrojen oran\u0131n\u0131 tahmin etmeye yard\u0131mc\u0131 olabilir. Bu oran, 3I\/ATLAS\u2019\u0131n y\u0131ld\u0131zlararas\u0131 alana girmeden \u00f6nce nas\u0131l olu\u015ftu\u011fu ve evrildi\u011fi konusunda ipucu sa\u011fl\u0131yor. Ara\u015ft\u0131rmac\u0131lar, kuyruklu y\u0131ld\u0131z Mars\u2019a en yak\u0131n ge\u00e7ti\u011finde hidrojen ve hidroksil da\u011f\u0131l\u0131m\u0131n\u0131 da haritalamay\u0131 ba\u015fard\u0131.<\/p>\n

Y\u00fczeydeki Perseverance arac\u0131 da kendi g\u00f6zlemini ger\u00e7ekle\u015ftirdi. Rover, 4 Ekim\u2019de uzun pozlama y\u00f6ntemiyle g\u00f6ky\u00fcz\u00fcnde hareket eden soluk bir lekeyi yakalad\u0131. Kamera uzun pozlama s\u0131ras\u0131nda sabit kald\u0131\u011f\u0131 i\u00e7in \u00e7evredeki y\u0131ld\u0131zlar \u00e7izgi halinde g\u00f6r\u00fcn\u00fcrken, kuyruklu y\u0131ld\u0131z donuk ve kompakt bir lekeden ibaret olarak kaydedildi.<\/p>\n

D\u00fcnya\u2019daki astronomlar, kuyruklu y\u0131ld\u0131z\u0131n i\u00e7 G\u00fcne\u015f Sistemi\u2019ne do\u011fru ilerleyi\u015fini izlemeye devam ediyor. \u015eu anda D\u00fcnya\u2019dan 305 milyon kilometreden daha uzakta bulunan kuyruklu y\u0131ld\u0131z, Aral\u0131k ortas\u0131nda en yak\u0131n noktaya, 268.7 milyon kilometreye ula\u015facak. Ard\u0131ndan yeniden y\u0131ld\u0131zlararas\u0131 uzaya geri d\u00f6necek.<\/p>\n

3I\/ATLAS\u2019\u0131n tekrar geri gelmesini beklemiyor.<\/p>\n\n
