Arianespace's Ariane 5 rocket carrying NASAs James Webb Space Telescope on December 25, 2021, in the Jupiter Center at the Guiana Space Center in Kourou, French Guiana. KOUROU, FRENCH GUIANA - DECEMBER 25: Launch teams monitor the countdown to the launch of. Some amateur astronomers caught Webb as it briefly orbited Earth: Webb will also be able to study the atmospheres of distant exoplanets in an effort to determine if any of them are Earth-like-and possibly host lifeforms. Webb’s primary mirror is fashioned from beryllium and made-up of 18 hexagonal segments, each one covered in a super-thin layer of gold because it’s perfect for reflecting infrared light.
