At the bottom of the ocean, volcanic vents spew boiling water, toxic metals, and acid strong enough to dissolve bone — yet life not only survives there, it flourishes. Microbes feed on chemical ...

Small, icy moons might be boiling under their surface. Many moons in the outer solar system are thought to harbor subsurface oceans beneath their icy crusts. New computer simulations, reported ...

Could ocean worlds in the outer solar system have boiling water underneath their icy crusts? This is what a recent study published in Nature Astronomy hopes to address as a team of scientists ...

Far from the Sun, beneath the frozen shells of moons like Europa and Enceladus, new research suggests that water may not simply sit as a quiet global ocean. Instead, it could churn, flash to vapor, ...

Icy moons circling the outer planets may be far more dynamic—and explosive—than they appear. New research suggests that when heat from tidal forces melts their ice shells from below, the sudden drop ...

A volcano is erupting under the ocean in the Bismarck Sea, prompting warnings of possible tsunamis from authorities as ash and smoke billow into the sky. Papua New Guinea authorities have warned of ...
