With Webb’s 21.3-foot (6.5-meter) primary mirror fully deployed, the infrared observatory has completed its unprecedented process of unfolding in space to prepare for science operations. The observatory will study every phase of cosmic history—from within our solar system to the most distant observable galaxies in the early universe.
