JWST, or the James Webb Space Telescope, is a large, space-based observatory designed to study the universe in infrared light. It is scheduled for launch in 2021 and is expected to revolutionize our understanding of the cosmos by observing distant galaxies, stars, and planetary systems. JWST will enable scientists to peer back in time to the early universe, observe the formation of galaxies and stars, study the atmospheres of exoplanets, and much more. Its advanced technology and capabilities make it a cutting-edge tool for exploring the mysteries of the universe.
