Mission Exploring the Universe from the solar neighbourhood to the most distant galaxies.
Name The James Webb Space Telescope honours NASA's second administrator, James E. Webb.
Partnership JWST is a joint project between NASA, ESA and the Canadian Space Agency (CSA).
Description JWST is a major space observatory often presented as the successor to the very successful NASA/ESA Hubble Space Telescope (HST). It has a large 6.5-metre segmented mirror that will collect almost 6 times more light than HST. It has also been designed to work with infrared light. It will address a broad variety of scientific topics ranging from detecting the first galaxies in the Universe to studying planets around other stars.
JWST mission facts
Scientists expect JWST:
- to find out more about the origins of the Universe by observing infrared light from the first stars and galaxies;
- to study the properties of planets around other stars, including looking for the signature of water in their atmosphere;
