James Webb Space Telescope

The James Webb Space Telescope (JWST) is a space telescope developed by the U.S. National Aeronautics and Space Administration (NASA) in collaboration with the European Space Agency (ESA) and the Canadian Space Agency (CSA) 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, and 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 and as of May 2022 is undergoing testing and alignment.
