The James Webb Space Telescope (JWST) is a space telescope designed to conduct infrared astronomy. As the largest telescope in space, it is equipped with high-resolution and high-sensitivity instruments, allowing it to view objects too old, distant , or faint for the Hubble Space Telescope . [ 9 ]

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. The launch (designated Ariane flight VA256 ) took place as scheduled at 12:20 UTC on 25 December 2021 on an Ariane 5 rocket that lifted off from the Guiana Space Centre in French Guiana .
This hot central star of about 100,000 K has now blown off its outer layers and is making the nebula fluoresce brightly from the emission of its intense ultraviolet radiation. [6] The 16th magnitude star is an A-type main-sequence star of type A2V, and is separated from the white dwarf by at least 1277 au . [ 7 ]
James Webb was born in 1906 and lived in rural Granville County, on the northern border of North Carolina. His father was the superintendent of Granville County Schools. Webb attended UNC-Chapel Hill.
Webb's First Deep Field. Webb's First Deep Field is the first operational image taken by the James Webb Space Telescope (JWST). The deep-field photograph, which covers a tiny area of sky visible from the Southern Hemisphere, is centered on SMACS 0723, a galaxy cluster in the constellation of Volans.
The James Webb Space Telescope (JWST) is an international 21st-century space observatory that was launched on 25 December 2021. [ 1 ] [ 2 ] It is intended to be the premier observatory of the 2020s, combining the largest mirror yet on a near-infrared space telescope with a suite of technologically advanced instruments from around the world.
Current estimates place the probability of finding an Earth-like planet around Alpha Centauri at roughly 75%. [125] The observational thresholds for planet detection in the habitable zones by the radial velocity method are currently (2017) estimated to be about 53 M E for Alpha Centauri A, 8.4 M E for Alpha Centauri B, and 0.47 M E for Proxima ...
