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 ...
The most powerful telescope to be launched into space has made history by detecting a record number of new stars in a distant galaxy. NASA's James Webb Space Telescope, history's largest and most ...
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 ...
NASA's powerful Webb Telescope has spotted more than 40 ancient stars in a distant galaxy, researchers said in a new study. The study, published Monday in Nature, said the researchers used a ...
NASA compares the required accuracy by analogy: "If the Webb primary mirror were the size of the United States, each [mirror] segment would be the size of Texas, and the team would need to line the height of those Texas-sized segments up with each other to an accuracy of about 1.5 inches".
