The James Webb Space Telescope (JWST or "Webb") is a space telescope that is the successor to the Hubble Space Telescope.The JWST will provide greatly improved resolution and sensitivity over the Hubble, and will 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, such as the formation of the first galaxies.
