The James Webb Space Telescope (JWST) is a space telescope developed by NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA).
As of December 2021, it will succeed the Hubble Space Telescope as NASA’s flagship astrophysics mission.
A monumental feat of engineering, this new telescope will provide improved infrared resolution and sensitivity over Hubble and enable a broad range of investigations across the fields of astronomy and cosmology, including observing some of the most distant events and objects in the universe.
