An overview of the James Webb Space Telescope design

The James Webb Space Telescope is jointly created by companies like NASA (National Aeronautics and Space Administration), ESA (European Space Agency), CSA (Canadian Space Agency ), and STScI (Space Telescope Science Institute ).
This is a special telescope because we can see further than the Hubble space telescope (launched in 1990, the first major optical telescope to be placed in space).
Determined to launch on 30 March 2021, NASA's James Webb telescope will investigate the history of the universe from the Big Bang to the creation of the alien planet and beyond.
It is created with about 1,000 crores USD.  It has a Wavelengths from 0.6 μm (orange); to 28.3 μm (mid-infrared), a focal length of 431 feet, 66.26 ft × 46.46 ft, and dimensions from 66.26 ft × 46.46 ft.
JWST is mainly created to capture infrared rays, we cannot see these rays with our eyes but we can see it with an infrared camera. Infrared images help us to see and study space more clearly than visible lights.
Gold is used to create a JWST mirror as gold is a metal that reflects infrared waves. Only 48 grams of gold are used to create a mirror.
It will focus on four key areas: the first light in the universe, the assembly of galaxies in the early universe, the birth of protoplanetary systems and stars, and planets (including the origin of life).
The James Webb Space Telescope (JWST) will strike up on an Ariane 5 rocket from French Guiana, then take 30 days to fly a million miles towards space. It will orbit around L2, a place close to Earth that is opposite to the sun, it has been a popular destination for many space telescopes, including the Herschel Space Telescope and the Plank Space Observatory.
JWST is differently shaped and created than the Hubble space telescope. It has 6.5 times greater mirror than Hubble telescope, so it can absorb more light and we can see further than Hubble telescope.
NASA has temporarily stopped working on the James Webb Space Telescope because of the coronavirus pandemic. NASA Administrator Jim Bridenstine on March 20 said

“We are going to take care of our people. That’s our first priority, Technology allows us to do a lot of what we need to do remotely, but, where hands-on work is required, it is difficult or impossible to comply with [Centers for Disease Control and Prevention] guidelines while processing spaceflight hardware, and where we can’t safely do that we’re going to have to suspend work and focus on the mission-critical activities.”
