Webb10 jan. 2024 · With the launch of the James Webb Space Telescope (JWST), mankind’s understanding of the universe — and its origins — will increase exponentially. The James Webb Space Telescope is shown with one of its two “wings” folded. Each wing holds three of its primary mirror segments. Webb20 feb. 2024 · The system is an optical-infrared telescope and the mirror coating will be a protected silver coating, which will provide high reflectivity and low emissivity in the planned imaging bands. Fig. 7. ... After precision fabrication of the JWST mirror segments, they require a special coating. Due to the target infrared imaging band, ...

One of the James Webb Space Telescope's science goals is to look back through time to when galaxies were young. Webb does this by observing galaxies that are very distant, at over 13 billion light years away from us. To see such far-off and faint objects, Webb needs a large mirror. A telescope’s sensitivity, or … Visa mer Webb Telescope's scientists and engineers determined that a primary mirror 6.5 meters (21 feet 4 inches) across is what was needed to measure the light from these distant galaxies. Building a mirror this large was … Visa mer The Webb Telescope team also decided to build the mirror in segments on a structure which folds up, like the leaves of a drop-leaf table, so that it can fit into a rocket. The mirror … Visa mer Once in space, getting these mirrors to focus correctly on faraway galaxies is another challenge. Actuators, or tiny mechanical motors, provide the answer to achieving a single perfect focus. The primary mirror … Visa mer The hexagonal shape allows for a roughly circular, segmented mirror with "high filling factor and six-fold symmetry." High filling factor means the segments fit together without gaps. If the … Visa mer Webb14 dec. 2024 · Now, while Webb's mirror segments are coated in gold, they are not made of solid gold.
