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 ]
James Edwin Webb (October 7, 1906 – March 27, 1992) was an American government official who served as Undersecretary of State from 1949 to 1952. He was the second Administrator of NASA from February 14, 1961, to October 7, 1968.
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 ...
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.
The survey methodology was designed such that the area that will be surveyed, essentially continuously, over an entire year (351 observation days) and makes up about 5% of the entire sky, will encompass the regions of sky (near the ecliptic poles) which will be observable at any time of year with the James Webb Space Telescope (JWST).

Webb's first operational image was the Webb's First Deep Field, released on July 11, 2022, with it being the deepest sharp infrared image of the universe to date. [55] The rest of the first set of images was released the next day, which include full-color processed images of the Carina Nebula , Southern Ring Nebula , Stephan's Quintet , as well ...
WASHINGTON (AP) — The U.S. economy added 818,000 fewer jobs from April 2023 through March this year than were originally reported, the government said Wednesday.
The James Webb Space Telescope's cryocooler is based originally on the TRW ACTDP cryocooler. [12] However, the JWST has had to develop a version to handle higher thermal loads. [13] It has a multi-stage pulse tube refrigerator that chills an even more powerful cooler. [12] That is a linear-motion Oxford-style compressor that powers a J-T loop. [13]
