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 ]
FGS/NIRISS ETU, 2016 FGS Test unit undergoes cryogenic testing, 2012 Infographic of JWST instruments and their observation ranges of light by wavelength. Fine Guidance Sensor and Near Infrared Imager and Slitless Spectrograph (FGS-NIRISS) is an instrument on the James Webb Space Telescope (JWST) that combines a Fine Guidance Sensor and a science instrument, a near-infrared imager and a ...
Infographic of JWST instruments and their observation ranges of light by wavelength. The James Webb Space Telescope's main science themes are: [5] First light and reionization; the assembly of galaxies, the birth of stars and protoplanetary systems; the birth of planetary systems and the origins of life
Infographic of JWST instruments and their observation ranges of light by wavelength. NIRCam has two complete optical systems for redundancy. [3] The two sides can operate at the same time, and view two separate patches of sky; the two sides are called side A and side B. [3] The lenses used in the internal optics are triplet refractors.

MIRI, or the Mid-Infrared Instrument, is an instrument on the James Webb Space Telescope. [1]
Astronomers used the James Webb Space Telescope to newly detect a high-speed jet stream over the equator of Jupiter. Webb telescope spots never-before-seen feature in Jupiter’s atmosphere Skip ...
where λ is the wavelength of the observed radiation, and D is the diameter of the telescope's objective. The resulting R is in radians. For example, in the case of yellow light with a wavelength of 580 nm, for a resolution of 0.1 arc second, we need D=1.2 m. Sources larger than the angular resolution are called extended sources or diffuse ...
The James Webb Space Telescope (JWST) launched in December 2021 and works simultaneously with Hubble. [17] Its segmented, deployable mirror is over twice as wide as the Hubble's, increasing angular resolution noticeably, and sensitivity dramatically. Unlike Hubble, JWST observes in the infrared, in order to penetrate dust at cosmological distances.
