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 ...

Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional ...

Researchers have found evidence of changes in the structure of the Earth's core. University of Southern California team, led by Professor John Vidale, was investigating the inner core's rotation – a ...

Deep beneath our feet, far beyond the reach of any drill, new research suggests that Earth’s center is far more intricate ...

Earth's inner core may be layered like an onion, with silicon and carbon creating distinct zones that explain seismic wave ...

Earth’s inner core has long puzzled scientists because seismic waves move through it unevenly. Compressional waves from ...

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 ...

A new study offers compelling evidence that Earth's inner core reversed direction and is slowing down.

Earth cross section showing the classic distinction between crust, mantle and core. But new research shows Earth's structure is far more complicated and may change over time. Analyzing an unusual ...

Scientists have discovered that Earth’s inner core may not be fully solid. A rare “superionic” state of matter could explain ...

The surface of Earth's inner core may be shape-shifting, new research suggests. The study, published Feb. 10 in the journal Nature, looked at earthquake waves that have skimmed the edge of the inner ...
