New research suggests that Earth’s solid inner core might not be as rigid as once believed. Instead, it could exist in an ...

Earth’s deep interior may hold water equal to today’s oceans, challenging long-held views of how the planet became habitable.

Scientists say they have found geochemical traces of Earth’s ancient self hidden far below our feet, suggesting that parts of the planet that existed before the Moon-forming collision 4.5 billion ...

Scientists studying Greenland have uncovered surprising heat variations deep beneath the ice that could reshape experts' understanding of future sea-level rise. The discovery, made using advanced 3D ...

Research shows the Pacific hemisphere is losing heat faster than the African hemisphere. The heat is from Earth’s molten interior, which causes continental drift. Landmass traps more heat than ...

New research sheds light on the earliest days of the earth's formation and potentially calls into question some earlier assumptions in planetary science about the early years of rocky planets.

New research reveals that Earth’s solid inner core is actually in a superionic state, where carbon atoms flow freely through a solid iron lattice. This unusual behavior makes the core soft, matching ...

Earth is fortunate in having a magnetic field: it protects the planet and its life from harmful cosmic radiation. Other planets in our solar system—such as Mars—are constantly bombarded by charged ...
