Webb telescope analyzes chemistry of hot gas giant's atmosphere.

Scientists have used data from the Webb Space Telescope to infer the chemistry of exoplanet WASP-39b, a hot gas giant located about 700 light-years from Earth. The planet's atmosphere contains carbon dioxide and sulfur dioxide, which is unexpected for a hydrogen-rich gas giant. The findings suggest that there are things going on in exoplanets that we wouldn't see in our own Solar System.
