The James Webb Space Telescope (Webb) is designed to answer outstanding questions about the Universe and to make breakthrough discoveries in all fields of astronomy.
Webb will see farther into our origins – from the Universe's first galaxies, to the birth of stars and planets, and exoplanets with the potential for life. Closer to home, Webb will also look at our own Solar System.

Webb is an international partnership between NASA, the European Space Agency (ESA) and the Canadian Space Agency (CSA).
