James Webb Uzay Teleskobu, asl\u0131nda selefi Hubble Uzay Teleskobu’ndan daha hafif. \u00c7o\u011fu durumda, bir \u015feyin daha b\u00fcy\u00fck bir versiyonu olu\u015fturulurken, daha a\u011f\u0131r ve daha b\u00fcy\u00fck olacakt\u0131r. Ancak bu, JWST i\u00e7in ge\u00e7erli de\u011fil.<\/p>\n

Hubble 2,4 metre \u00e7ap\u0131ndayd\u0131, sa\u011flam bir ana aynas\u0131 ve 4.0 metrekarelik bir alan\u0131 vard\u0131.

Uzun y\u0131llard\u0131r f\u0131rlat\u0131lmas\u0131 beklenen teleskobun ismi ise eski bir NASA y\u00f6neticisi olan James Edwin Webb’den geliyor.<\/p>\n

Uzun soluklu bu \u00e7al\u0131\u015fman\u0131n nedeni ise James Webb’in Hubble’\u0131n yerini almas\u0131 ve ileri d\u00fczeydeki donan\u0131mlar\u0131 sayesinde evrenin yakla\u015f\u0131k 13,7 milyar y\u0131l \u00f6nce olu\u015fumuna \u0131\u015f\u0131k tutabilmek\u2026<\/p>\n
