Earth’s core has often been described as just a giant ball of iron and nickel. Now, a new study argues that it is also a ...

A team of researchers has produced the strongest experimental evidence yet that Earth’s iron core holds enormous quantities of hydrogen, potentially equivalent to 9 to 45 oceans’ worth of water. The ...

While most of us take the ground beneath our feet for granted, written within its complex layers, like the pages of a book, is Earth's history. Our history. Research shows there are little-known ...

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 ...

As much as 45 oceans’ worth of hydrogen may be in Earth’s core, scientists reported, suggesting most of Earth’s water was ...

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 ...

Precious metals may be escaping from the planet’s core. This hotly debated subject could help us understand Earth’s evolution and determine whether life exists elsewhere in the Universe ...

Understanding inner core oscillations is key to grasping Earth's rotation variations and magnetic field changes, linking deep processes to surface effects.
