Seeing the universe's first light
The James Webb Space Telescope is the most powerful observatory ever launched, operating at L2 in infrared wavelengths to observe the earliest galaxies, stellar nurseries, and exoplanet atmospheres. Since its first images in 2022, JWST has already rewritten cosmology textbooks and discovered galaxies that challenge existing models of the early universe.
