Previously, it was believed that Jupiter, the largest planet, was responsible for most of the tidal heating associated with the liquid interiors of its moons. Jupiter’s moons are hot. Well, hotter ...

Alien planets might experience tidal forces powerful enough to remove all their water, leaving behind hot, dry worlds like Venus, researchers said. These findings might significantly affect searches ...

An international research team has found that there is an extremely soft layer deep inside the Moon and that heat is effectively generated in the layer by the gravity of the Earth. These results were ...

Seismology has revealed much of the basics about earthquakes: Tectonic plates move, causing strain energy to build up, and that energy eventually releases in the form of an earthquake. As for ...
