JWST Maps Exoplanet Atmosphere in 3D
Astronomers have achieved a groundbreaking feat by creating the first-ever three-dimensional atmospheric map of the exoplanet WASP-18b using the James Webb Space Telescope. This unprecedented map of the "ultra-hot Jupiter" revealed astonishing temperature contrasts, including regions hot enough to destroy water molecules, offering new insights into extreme planetary conditions and atmospheric dynamics on distant worlds.
