James Webb Space Telescope Briefing

NASA James Webb Space Telescope Operations Project Scientist Jane Rigby answers questions from the media during a briefing following the successful deployment of NASA’s James Webb Space Telescope primary mirror, Saturday, Jan. 8, 2022, from the Webb Space Telescope Mission Operations Center at the Space Telescope Science Institute in Baltimore. 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. Photo Credit: (NASA/Bill Ingalls)
