Hubble pioneered the search for some of the intrinsically faintest and youngest galaxies ever detected. Webb’s infrared view significantly bolsters this deep look by going even farther into the early universe with its infrared vision, the JWST was built on three decades of discoveries by the iconic Hubble Space Telescope. While JWST is sometimes called Hubble’s replacement, while Nasa see it as its as a successor. JWST was designed to pick up where Hubble left off in studying the early universe. 

Hubble sees ultraviolet light, visible light, and a small slice of infrared. Although JWST is optimized for infrared, it overlaps a little with Hubble and can see red, orange, and gold visible light, while the JWST and Hubble also complement each other’s capabilities. Scientists will have the unprecedented opportunity to observe objects with both JWST and Hubble simultaneously, bringing the cosmos to life in a wide range of light.
