The James Webb Space Telescope is a space telescope designed primarily to conduct infrared astronomy. The most powerful telescope ever launched into space, its greatly improved infrared resolution and sensitivity will allow it to view objects too old, distant, or faint for the Hubble Space Telescope. This is expected to enable a broad range of investigations across the fields of astronomy and cosmology, such as observations of first stars and the formation of the first galaxies, and detailed atmospheric characterization of potentially habitable exoplanets. JWST was launched in December 2021 on a European Space Agency Ariane 5 rocket from Kourou, French Guiana, and entered orbit in January 2022; as of July 2022, it is undergoing instrument modes check-out. Once operational, expected about the beginning of July 2022, JWST is intended to succeed the Hubble as NASA's flagship mission in astrophysics.
