The James Webb Space Telescope, an international partnership with the European and Canadian space agencies, is targeted for launch Dec. 18. It will explore every phase of cosmic history – from within our solar system to the most distant observable galaxies in the early universe, and everything in between. Webb will reveal new and unexpected discoveries, and help humanity understand the origins of the universe and our place in it.
