A 3D map of planet WASP-18b reveals extreme heat zones and broken water vapor in its atmosphere for the first time.

Tests on olivine hint that water-rich exoplanets could generate H2O internally, possibly explaining ocean worlds and even some of Earth’s early water.

A team of astronomers used the James Webb Space Telescope to create the first 3D atmospheric map of an exoplanet. The fiery WASP-18b, a massive “ultra-hot Jupiter,” revealed striking temperature ...
