The Webb telescope uses 132 small actuation motors to position and adjust the optics. [39] The actuators can position the mirror with 10 nanometer accuracy. [40] Webb's optical design is a three-mirror anastigmat, [41] which makes use of curved secondary and tertiary mirrors to deliver images that are free from optical aberrations over a wide ...
The most powerful telescope to go into space was successfully launched on Christmas Day. The James Webb Space Telescope (JWST) was on an Ariane 5 rocket when it left the Kourou spaceport in French ...
Unknown: Cosmic Time Machine is an episode of the four-episode 2023 Netflix documentary series Unknown, about NASA's development and launch of the James Webb Space Telescope. [1] The episode follows the development of the telescope from the 1990s through its 2021 launch and 2022 deployment, and the unveiling of some of the first images from the ...
Webb's First Deep Field was taken by the telescope's Near-Infrared Camera (NIRCam) and is a composite produced from images at different wavelengths, totalling 12.5 hours of exposure time. [3] [4] SMACS 0723 is a galaxy cluster visible from Earth's Southern Hemisphere, [5] and has often been examined by Hubble and other telescopes in search of ...
A team of scientists put Webb's abilities to the test when the newly discovered galaxy nicknamed Firefly Sparkle was discovered and "weighed" using Webb's data, according to the Space Telescope ...
Two years of data from NASA's James Webb Space Telescope have now validated the Hubble Space Telescope's earlier finding that the rate of the universe's expansion is faster - by about 8% - than ...
Technicians work on a mock-up of the JWST spacecraft bus in 2014 [1] The spacecraft bus is a carbon fibre box that houses systems of the telescope and so is the primary support element of the James Webb Space Telescope, launched on 25 December 2021. It hosts a multitude of computing, communication, propulsion, and structural components. [2]
Infrared light is invisible to the human eye, and the Webb telescope’s unprecedented capabilities have been used over the past year to spot many newly observed celestial features, such as ...
