The James Webb Space Telescope was launched on December 25, 2021, with commissioning complete in early July 2022. With its 6.5-meter golden eye, cameras and spectrometers, the Webb Telescope is already producing magnificent images of galaxies, active galactic nuclei, star-forming regions, and planets.
Scientists are beginning to observe the growth of galaxies, the formation of stars and planetary systems, individual exoplanets through coronagraphy and transit spectroscopy, and all objects in the Solar System from Mars and beyond. In this year's Paint Branch Lecture, John Mather will explain how he and his team built the Webb Telescope and the discoveries they hope to make with its data. The Webb Telescope is a joint project of NASA with the European and Canadian space agencies.
Paint Branch is a 14-mile stream that brings water from small streams and tributaries throughout the region, flowing south through our campus on its way to the Anacostia River. Many of us pass it by car, bicycle, or on foot each day on our way to and from work. Like the Paint Branch, we anticipate that this new lectureship will serve as a confluence that draws together the many talented and active researchers, faculty, and students in applied physics in our communiy and will remind us of our common goals and principles.Lecture Archive
