Tidal heating converts repeated gravitational deformation into internal heat.
supportedTidal heating converts repeated gravitational deformation into internal heat. Tidal heating expands the range of environments where liquid water can persist far beyond the classical stellar habitable zone.

Tidal heating converts repeated gravitational deformation into internal heat.
supportedAs a moon moves through an eccentric orbit, the planet's tidal force changes in strength and direction.
supportedIo's intense volcanism requires a major internal heat source, Europa's induced magnetic signature supports a global salty ocean, and Enceladus's south-polar heat flow and water-rich plumes demonstrate active internal heating.
