Aktar\u0131ld\u0131\u011f\u0131 kadar\u0131yla James Webb Uzay Teleskobu’ndan gelen yeni g\u00f6r\u00fcnt\u00fc,\u00a0y\u00fcksek y\u0131ld\u0131z olu\u015fum oran\u0131na ve s\u00fcpernova patlamalar\u0131na sahip olan PLCK G165.7+67.0 (k\u0131saca G165) galaksi k\u00fcmesinden al\u0131nd\u0131. A\u015fa\u011f\u0131da da g\u00f6r\u00fclebildi\u011fi gibi g\u00f6zlemlenen g\u00f6r\u00fcnt\u00fcde bir \u0131\u015f\u0131k izi ve \u00fc\u00e7 parlak nokta var. Bu noktalar, patlayan bir beyaz c\u00fcce y\u0131ld\u0131z\u0131<\/strong> temsil ediyor.<\/p>\n

Bu s\u00fcre\u00e7te patlaman\u0131n \u0131\u015f\u0131\u011f\u0131, \u00f6n\u00fcndeki galaksiler nedeniyle k\u00fctle\u00e7ekimsel bir lens gibi b\u00fck\u00fclerek birden fazla g\u00f6r\u00fcnt\u00fc olu\u015fturuyor. Ara\u015ft\u0131rma ekibinde bulunan Dr. Brenda Frye ise, bu durumu, bir aynada ayn\u0131 ki\u015finin farkl\u0131 a\u00e7\u0131lardan g\u00f6r\u00fclen g\u00f6r\u00fcnt\u00fclerine benzetiyor. Bu da teleskobun erken, orta ve son patlama evrelerini ayn\u0131 anda kaydetmesini sa\u011flad\u0131.<\/p>\n

<\/span> NASA’n\u0131n yeni ke\u015ffi, ayn\u0131 zamanda \u015fimdiye kadar g\u00f6zlemlenen en uzak Tip Ia s\u00fcpernova olarak da \u00f6ne \u00e7\u0131k\u0131yor ve\u00a0evrenin geni\u015fleme h\u0131z\u0131n\u0131 g\u00f6steren Hubble sabiti hakk\u0131nda bilgi verebilir. <\/figure>\n

Hubble sabiti i\u00e7in k\u0131saca evrenin ne kadar h\u0131zl\u0131 geni\u015fledi\u011fini anlatan bir say\u0131 diyebiliriz. Bilim insanlar\u0131 bu de\u011feri hen\u00fcz tam olarak belirleyebilmi\u015f de\u011fil. Ancak yeni s\u00fcpernova g\u00f6r\u00fcnt\u00fcs\u00fc, bu de\u011feri daha net bir \u015fekilde hesaplamaya yard\u0131mc\u0131 olabilir. Frye, bu s\u00fcpernovaya, astronomlar\u0131n evrenin geni\u015fleme h\u0131z\u0131n\u0131 daha iyi anlamalar\u0131na \u0131\u015f\u0131k tuttu\u011fu i\u00e7in “SN H0pe” ad\u0131n\u0131 verdiklerini s\u00f6yl\u00fcyor.<\/p>\n

Daha \u00f6nce Chicago \u00dcniversitesi’nden bir ekip, Hubble sabitini 72 olarak bulmu\u015ftu. Di\u011fer ara\u015ft\u0131rmac\u0131lar ise bu de\u011feri 69.8 ile 74 aras\u0131nda hesaplad\u0131. James Webb ekibi ise, bu de\u011feri biraz daha y\u00fcksek, 75.4 olarak \u00f6l\u00e7t\u00fc. Ancak elde edilen sonu\u00e7lar daha fazla g\u00f6zlem gerektiriyor ve gelecekteki ara\u015ft\u0131rmalar bu konuda daha kesin sonu\u00e7lar sa\u011flayabilir.<\/p>\n\n
