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 ...

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

Add Yahoo as a preferred source to see more of our stories on Google. Researchers have found evidence of changes in the structure of the Earth's core. University of Southern California team, led by ...

A geomagnetic field is generated in Earth's interior and extends into outer space to protect Earth from cosmic radiation and the charged particles of solar wind. The magnetic field is generated by the ...

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 ...

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

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 ...

Earth's inner core is solid and blistering hot. For decades, scientists have known the inner core is solid thanks to the pioneering work of Danish seismologist Inge Lehmann, who first proposed its ...

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 ...
