JWST detected carbon dioxide in WASP-39b's atmosphere for the first time, revealing thick clouds of sulfur and silicates that interact with starlight to produce sulfur dioxide. Chemical ratios in the atmosphere suggest the gas giant formed from colliding planetesimals and migrated closer to its star after formation, offering insights into planetary origins.
