James Webb Space Telescope

The James Webb Space Telescope (JWST), also known as Webb, is a large, infrared-optimized space telescope that was launched on 25 December 2021. It is the successor to the Hubble Space Telescope and is designed to provide improved infrared resolution and sensitivity over Hubble. The primary mirror of JWST, which is composed of 18 hexagonal mirror segments made of gold-plated beryllium, has a diameter of 6.5 meters (21.3 feet). The telescope is named after James E. Webb, who was the administrator of NASA from 1961 to 1968 during the Apollo program. The JWST is a joint project of NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA). In Hebrew, it is called טלסקופ החלל ג'יימס ווב (Teleskop Haḥalal Yames Vuv). In French, it is known as the Télescope spatial James Webb, and in Spanish, it is called the Telescopio Espacial James Webb.
