SCaN A to Z

The James Webb Space Telescope (also known as Webb) is an orbiting telescope that will complement the discoveries of the Hubble Space Telescope.

The Hubble Space Telescope sends back images and data to Earth that has led to many discoveries about outer space. Webb will have even more capabilities to capture and send data back to Earth.

Webb will observe dust clouds where stars and planets are forming today. It will look much closer to the beginning of time to hunt for the unobserved formation of the first galaxies.
