Scientists are working to solve a mystery of Earth’s molten outer core, which lies more than 2,000 kilometers beneath our feet ...

Geophysicists from ETH Zurich and SUSTech, China, have demonstrated the dynamo effect of the Earth’s core in a model in which viscosity has no influence, as is the correct physical regime for the ...

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 ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects of viscosity in their simulation, they revealed a self-sustaining dynamo ...

The composition of Earth’s core is crucial to understanding several fundamental processes of its evolution, including the early core-mantle differentiation 1,2, inner core crystallization and growth 3 ...

Beneath roughly 5,150 kilometers of rock, liquid metal, and extreme pressure, Earth’s solid inner core sits at temperatures ...

Scientists have long known that Earth's core is mostly made of iron, but the density is not high enough for it to be pure iron, meaning lighter elements exist in the core, as well. In particular, it's ...

Deep beneath the Pacific near the equator, Earth’s outer core now flows east instead of west. Dynamics deeper within our planet’s core may help explain the change and what to expect in the near future ...
