James Webb Space Telescope (NASA, ESA, CSA): Launched in 2021, the James Webb Space Telescope (JWST) is the most powerful space observatory ever built. Positioned at the Sun-Earth L2 point, it observes primarily in infrared, allowing it to see the first galaxies formed after the Big Bang, peer through dust clouds, and analyze exoplanet atmospheres. JWST has already captured detailed images of nebulae, galaxy clusters, and distant stars, surpassing Hubble’s capabilities. It detected water, carbon dioxide, and other molecules on exoplanets, advancing the search for habitable worlds. A collaboration between NASA, ESA, and CSA, JWST features a 6.5-meter segmented mirror and sunshield. Its complex deployment and flawless operation mark an engineering triumph. With a planned 10-year mission, JWST is revolutionizing cosmology, star formation, and planetary science, offering unprecedented insights into the origins and evolution of the universe.
