Read the latest news on the James Webb Space Telescope, the large, space-based observatory that will complement and extend the discoveries of the Hubble Space Telescope. With its 6.5-meter primary mirror, Webb offers longer wavelength coverage and vastly improved sensitivity, allowing it to look further back in time to view the first galaxies that formed in the early universe and to peer inside dust clouds where stars and planets are forming today.
