James Webb Space Telescope lifts off to reveal early galaxies, exoplanets [i]The world's largest and most powerful space telescope has made it safely off the planet, but it still has a complex deployment and a million-mile journey before it can start revealing the universe like never before. The James Webb Space Telescope (JWST), named after the Apollo-era NASA administrator who championed space science, is an infrared observatory that will be used to image the earliest galaxies and to discern the atmospheric properties of exoplanets. It is intended as the scientific successor for the Hubble and Spitzer space telescopes, which remain in operation. On Saturday (Dec. 25), an Ariane 5 rocket carrying the intricately-folded Webb lifted off from Arianespace's ELA-3 launch complex at Europe's Spaceport located near Kourou, French Guiana. The 7:20 a.m. EST (1220 GMT or 9:20 a.m. local time) launch began a 27-minute powered climb into space that culminated in the telescope separating from its rocket's upper stage and automatically deploying its solar array within a half hour of leaving Earth.[/i]
