The James Webb Space Telescope (JWST) is a large, infrared-optimized space telescope developed by NASA, in collaboration with the European Space Agency (ESA) and the Canadian Space Agency (CSA). The JWST is considered the successor to the Hubble Space Telescope and is set to launch in 2021.

The JWST has a primary mirror with a diameter of 6.5 meters (21.3 feet) and will be located at the second Lagrange point (L2) of the Earth-Sun system, which is about 1.5 million kilometers (0.99 million miles) away from Earth. The JWST is designed to study the early universe, galaxy formation, and evolution of galaxies, including the study of exoplanets and the potential for life beyond our solar system.

The JWST will be equipped with four scientific instruments: the Near Infrared Camera (NIRCam), the Near Infrared Spectrograph (NIRSpec), the Mid-Infrared Instrument (MIRI), and the Fine Guidance Sensor/Near InfraRed Imager and Slitless Spectrograph (FGS/NIRISS). These instruments will enable the telescope to observe the universe in unprecedented detail and depth.
