Abstract: James Web Space Telescope (JWST) is a milestone to space exploration. JWST is concerned to observe the universe in infrared spectrum, provide unprecedented insight into the early universe, study formation of galaxies and birth of stars, give significant understanding of planetary system and discover signs of life on other planets. To sustain the hostile environment of space, cryogenic cooling system is used to keep telescope operational even at extremely low temperature just above absolute zero. Three-stage Pulse Tube precooler and a single Joule-Thomson cryocooler is used to generate cooling effect for effecting cooling of instruments and detectors. These instruments and detectors are responsible for providing data of astronomical phenomena and capturing high quality pictures of the planet, galaxies, stars, black holes and other astronomical objects.
