The James Webb Space Telescope ( sometimes called JWST ) is an orbiting infrared observatory that will complement and extend the discoveries of the Hubble Space Telescope , with longer wavelength coverage and greatly improved sensitivity . The longer wavelengths enable the Webb telescope to look much closer to the beginning of time and to hunt for the unobserved formation of the first galaxies , as well as to look inside dust clouds where stars and planetary systems are forming today .
