Unlike the Hubble, which observes in the near ultraviolet, visible, and near infrared (0.1 to 1 μm) spectra, the JWST will observe in a lower frequency range, from long-wavelength visible light through mid-infrared (0.6 to 27 μm), which will allow it to observe high redshift objects that are too old and too distant for the Hubble to observe.[9] The telescope must be kept very cold in order to observe in the infrared without interference, so it will be deployed in space near the Earth–Sun L2 Lagrangian point, and a large sunshield made of silicon- and aluminum-coated Kapton will keep its mirror and instruments below 50 K (−220 °C; −370 °F).[10] The JWST is being developed by NASA—with significant contributions from the European Space Agency and the Canadian Space Agency[1]—and is named for James E. Webb, who was the administrator of NASA from 1961 to 1968 and played an integral role in the Apollo program.[11][12] Development began in 1996 for a launch that was initially planned for 2007, but the project has had numerous delays and cost overruns, and underwent a major redesign in 2005. The JWST's construction was completed in late 2016, after which its extensive testing phase began.[13][14] In March 2018, NASA delayed the launch after the telescope's sunshield ripped during a practice deployment.[15] Launch was delayed again in June 2018 following recommendations from an independent review board, and is currently scheduled for March 2021. #आखिर #कैसे #पता #चलता #है #यूनिवर्स #के #बारे #मैं ------------------------------------------------ VOICE OVER - PRADEEP SONI SCRIPT WRITER - NICKY SONI OFFICIAL NICKY SONI ------------------------------------------------- YOUTUBE - http://www.youtube.com/c/EPICENTERTAINMENT INSTAGRAM- https://www.instagram.com/neeraj.soni.7777/ FACEBOOK- https://www.facebook.com/positivenickywave TWITTER- https://twitter.com/soninicky69 INSTAGRAM- https://www.instagram.com/epicentertainment77/
