    • Abstract

       

      The James Webb Space Telescope, or JWST, or simply Webb, is a large, space-based observatory, designed primarily to con­duct infrared astronomy. The telescope is named after James Edwin Webb (1906-1992), who was the second administrator of NASA during 1961-1968. It is an advanced next-generation telescope that will complement and extend the discoveries of the Hubble Space Telescope. The JWST has been developed by the National Aeronautics and Space Administration (NASA) of the United States of America in collaboration with the European Space Agency (ESA) and the Canadian Space Agency (CSA). It took over 24 years to place the Webb on the launch pad. The Webb was launched on 25 December 2021 at 7:20 AM (12:20 UTC) onboard ESA's Ariane S rocket from Kourou, French Guiana.
