The James Webb Space Telescope (JWST) is the successor to Hubble and the most powerful space telescope ever built. It has a larger mirror that allows it to observe fainter and more distant objects. One of its key goals is to study the early universe and formation of galaxies, stars, and planets. It will provide insights into the origins of the universe by observing the most distant objects. The JWST observes primarily in infrared and has instruments to study a wide range of astronomical phenomena, from exoplanets to distant galaxies.
