James Webb Space Telescope

Launched December 2021

James Webb Space Telescope

The James Webb Space Telescope’s revolutionary technology will study every phase of cosmic history—from within our solar system to the most distant observable galaxies in the early universe. Webb’s infrared telescope will explore a wide range of science questions to help us understand the origins of the universe and our place in it.

Webb will directly observe a part of space and time never seen before. Webb will gaze into the epoch when the very first stars and galaxies formed, over 13.5 billion years ago. Ultraviolet and visible light emitted by the very first luminous objects has been stretched or “redshifted” by the universe’s continual expansion and arrives today as infrared light. Webb is designed to “see” this infrared light with unprecedented resolution and sensitivity.
