Scientists are unraveling the mysteries of "steam worlds"—exoplanets known as sub-Neptunes that are rich in water but orbit so close to their stars that their surfaces are shrouded in thick atmospheres of vapor. Using advanced models, researchers at UC Santa Cruz are now mapping how water behaves under extreme pressures and temperatures, offering insights into exotic phases like supercritical fluids and superionic ice.
