Measurements of seismic waves over many years suggest the Earth's core is deformed and reshaped by conditions of extreme heat ...

Continent-sized structures of mineral protruding from the lower mantle towards Earth's outer core may be contributing to an instability of our planet's magnetic field. The two odd formations – one ...

These chemical oddities may explain why Earth seems to be deficient in certain elements — and could prove useful in catalysts ...

Deep beneath our feet, far beyond the reach of any drill, new research suggests that Earth’s center is far more intricate than a simple metal ball. Instead of a single solid sphere, the inner core ...

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 ...

James is a published author with multiple pop-history and science books to his name. He specializes in history, space, strange science, and anything out of the ordinary.View full profile James is a ...

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 inner core has both changed its relative rotation rate and deformed in the past few decades, according to an analysis of seismic waves recorded when the inner core occupied the same relative ...

The inner core was discovered in 1936, and its size (about 20% of Earth's radius) is one of the best-constrained properties of the deep Earth. We use this information to estimate the core's ...

Gear-obsessed editors choose every product we review. We may earn commission if you buy from a link. Why Trust Us? A new study analyzing decades of seismogram data shows that physical changes can ...

A bullet-speed experiment reveals that the Earth's inner core may be softer and more dynamic than previously thought.

The Earth’s inner core, a solid sphere predominantly composed of iron and nickel, occupies a central role in our planet’s evolution and geodynamo processes. Although hidden beneath thousands of ...
