James Webb Space Telescope
The James Webb Space Telescope (JWST) is a space-based infrared observatory led by NASA with contributions from the European Space Agency and the Canadian Space Agency. Launched on December 25, 2021, it operates in a halo orbit around the Sun–Earth L2 Lagrange point about 1.5 million kilometers from Earth to study the early universe, galaxy evolution, star and planet formation, and exoplanet atmospheres. JWST’s 6.5-meter segmented, gold-coated beryllium mirror and five‑layer sunshield enable unprecedented sensitivity from 0.6 to 28.5 microns.
