SPHEREx’in 28 \u015eubat Cuma g\u00fcn\u00fc f\u0131rlat\u0131lmas\u0131 planlan\u0131yor.

NASA’n\u0131n Jet Propulsion Laboratory’den astrofizik\u00e7i Olivier Dor\u00e9, \u201cG\u00f6ky\u00fcz\u00fcndeki her \u015feyi g\u00f6zlemleyerek her pikselin spektrumunu alaca\u011f\u0131z. \u0130ster bir kuyruklu y\u0131ld\u0131z, ister bir gezegen, bir y\u0131ld\u0131z yahut galaksi olsun, t\u00fcm objeleri inceleyece\u011fiz\u201d dedi.<\/p>\n

SPHEREx’in ismi, \u0130ngilizce \u201cSpectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer\u201d (Evrenin Tarihi, \u0130yonizasyon \u00c7a\u011f\u0131 ve Buz Ara\u015ft\u0131rmac\u0131s\u0131 i\u00e7in Spektro-Fotometre) tabirinden geliyor. Vazifenin \u00fc\u00e7 temel maksad\u0131 var:<\/p>\n

  1. B\u00fcy\u00fck Patlama\u2019n\u0131n \u00e7abucak akabinde cihan\u0131n nas\u0131l g\u00f6r\u00fcnd\u00fc\u011f\u00fcn\u00fc anlamak.<\/li>\n
  2. T\u00fcm galaksilerden yay\u0131lan \u0131\u015f\u0131\u011f\u0131n toplam \u00f6l\u00e7\u00fcs\u00fcn\u00fc hesaplamak.<\/li>\n

    SPHEREx, kozmosun geni\u015flemesi s\u0131ras\u0131nda \u0131\u015f\u0131\u011f\u0131n nas\u0131l de\u011fi\u015fti\u011fini tahlil ederek kaynaklar\u0131n ne kadar uzakta oldu\u011funu ve bizden uzakla\u015f\u0131p uzakla\u015fmad\u0131\u011f\u0131n\u0131 belirleyebilecek. Vazifenin sonunda, yakla\u015f\u0131k 450 milyon galaksinin yer ald\u0131\u011f\u0131 devasa bir 3D harita olu\u015fturulacak.<\/p>\n

    Bu harita, B\u00fcy\u00fck Patlama’dan \u00e7abucak sonra ger\u00e7ekle\u015fti\u011fi d\u00fc\u015f\u00fcn\u00fclen kozmik enflasyon (evrenin ans\u0131z\u0131n geni\u015flemesi) teorisini test etmek i\u00e7in kullan\u0131labilir. Galaksilerin kainatta nas\u0131l da\u011f\u0131ld\u0131\u011f\u0131 incelendi\u011finde, kolay bir geni\u015fleme modeli mi yoksa bilinmeyen fizik\u00ee fakt\u00f6rlerin mi rol oynad\u0131\u011f\u0131 anla\u015f\u0131labilir.<\/p>\n

    Bunun yan\u0131 s\u0131ra, SPHEREx bilgileri kozmostaki toplam \u0131\u015f\u0131k \u00f6l\u00e7\u00fcs\u00fcn\u00fc hesaplamak i\u00e7in kullan\u0131labilecek. Galaksilerden yay\u0131lan \u0131\u015f\u0131\u011f\u0131n kayna\u011f\u0131n\u0131 ve vakit i\u00e7indeki de\u011fi\u015fimini belirlemek, cihan\u0131n ge\u00e7mi\u015fine dair k\u0131ymetli ipu\u00e7lar\u0131 sunabilir.<\/p>\n

    SPHEREx ayr\u0131yeten Samanyolu\u2019nda hayat ihtimalini ara\u015ft\u0131rmak i\u00e7in su ve \u00f6teki organik bile\u015fenleri tespit etmeye \u00e7al\u0131\u015facak. Y\u0131ld\u0131zlar\u0131n olu\u015ftu\u011fu molek\u00fcler bulutlardaki su buzu, karbondioksit ve karbon monoksit \u00fczere bile\u015fenler incelenerek bu elementlerin gezegenlere ta\u015f\u0131n\u0131p ta\u015f\u0131nmad\u0131\u011f\u0131 anla\u015f\u0131labilecek.<\/p>\n

    SPHEREx\u2019in toplayaca\u011f\u0131 devasa bilgi seti, James Webb Uzay Teleskobu (JWST) \u00fczere daha g\u00fc\u00e7l\u00fc teleskoplarla birlikte kullan\u0131ld\u0131\u011f\u0131nda daha da b\u00fcy\u00fck ke\u015fifler yap\u0131lmas\u0131n\u0131 sa\u011flayabilir. Astrofizik\u00e7i Gary Melnick, \u201cSPHEREx k\u0131ymetli bir b\u00f6lge ke\u015ffederse, James Webb Teleskobu bu noktalar\u0131 daha detayl\u0131 inceleyebilir.
