JWST maps the weather on a hot gas giant 700 light-years away - Ars Technica

The James Webb Space Telescope produced the first weather map of a hot gas giant about 700 light‑years away, revealing large differences in temperature and composition across the planet. Those contrasts suggest that standard techniques for interpreting exoplanet atmospheres may miss important spatial variability and could bias conclusions. The result adds to a pattern of surprising atmospheric findings and underscores the need for both detailed follow-ups and wider infrared surveys to better understand exoplanet climates.
