The James Webb Space Telescope (JWST) is successor to the Hubble telescope and the next great space science observatory, designed to answer questions about the Universe and to make breakthrough discoveries in all fields of astronomy. It is the most powerful space telescope ever built and a complex piece of mechanical, optical, and electronic machinery that has pushed the limits of human engineering. On December 25, 2021, after years of delays, the telescope was launched into space to usher in the next era of astronomy. The James Webb Space Telescope is an international partnership between NASA, ESA (European Space Agency), and CSA (Canadian Space Agency).
