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

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

The Earth's internal layers including the mantle, outer core, and inner core. Scientists believe that the inner core’s rotation began to slow down in 2010, but what that really means has been up for ...

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

Deep inside Earth is a solid metal ball that rotates independently of our spinning planet, like a top whirling around inside a bigger top, shrouded in mystery. This inner core has intrigued ...

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 ...

Deep beneath the Earth's surface, the inner core has long been thought of as a solid sphere, steadily growing as the outer core cools and crystallizes. However, a new study suggests that the inner ...

LOS ANGELES — Scientists have just detected something unusual happening 3,000 miles beneath our feet. New research from an international study reveals that Earth’s inner core, a ball of mostly iron ...

Geophysicist John Vidale noticed something striking while tracking the way seismic waves move from Earth’s crust through its core. The very center of the planet, a solid ball of iron and nickel ...

Deep beneath our feet, at a staggering depth of over 5,100km, lies Earth's inner core — a solid ball of iron and nickel that plays a crucial role in shaping the conditions we experience on the surface ...
