Even though it has only recently started taking observations, the James Webb Space Telescope has captured some of the sharpest and most detailed images of galaxies, nebulae and the distant universe.
Launched on 21 December 2021, JWST consists of a 6.5-metre diameter mirror made up of 18 hexagonal segments. The telescope is equipped with four instruments: Near Infrared Camera (NIRCam); Near Infrared Spectrograph (NIRSpec), Mid Infrared Instrument (MIRI) and Fine Guidance Sensors/Near Infrared Imager and Slitless Spectrograph (FGS/NIRISS). It is in orbit 1.5 million km from Earth.
