Webb, an infrared telescope with a 21.3-foot (6.5-meter) primary mirror, was folded up for launch and underwent an unprecedented deployment process to unfold in space. As NASA's next flagship observatory, Webb will study every phase of cosmic history—from within our solar system to the most distant observable galaxies in the early universe.
