The telescope is named after James E. Webb, who was the administrator of NASA from 1961 to 1968 during the Mercury, Gemini, and Apollo programs. Webb's primary mirror consists of 18 hexagonal mirror segments made of gold -plated beryllium , which together create a 6.5-meter-diameter (21 ft) mirror, compared with Hubble's 2.4 m (7 ft 10 in).

The James Webb Space Telescope (JWST) is a space telescope designed primarily to conduct infrared astronomy. Its complex launch and commissioning process lasted from late 2021 until mid-2022. The U.S. National Aeronautics and Space Administration (NASA) led JWST's development in collaboration with the European Space Agency (ESA) and the ...
A team of scientists published their findings this week using Nasa's James Webb Space Telescope (JWST) to cross-check the physics problem known as "Hubble Tension," which refers to Hubble Space ...
Nearly a month after launch, a trajectory correction was initiated to place the James Webb Space Telescope into a halo orbit at L 2. [ 48 ] [ 49 ] Its next five months were spent cooling NIRCam and the Mid-Infrared Instrument down further, aligning and calibrating its mirrors while focusing on HD 84406, a bright star in the constellation Ursa ...
