Earth's core contains up to 45 times more hydrogen than the oceans do, making it the largest hydrogen reservoir on the planet, a new study suggests. Researchers found that this vast amount of hydrogen ...

A new scientific revelation reveals that deep in the Earth’s core lies a good amount of hydrogen as well as a large amount of iron. While the iron in the core has always been recognized as dominant, ...

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 ...

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 ...

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 ...
