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 ...

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.

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 ...

The mysteries of Earth’s inner core have long been a topic of intrigue for scientists, with the planet’s central engine playing a key role in shaping our world. Recent research has unveiled an ...

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 ...

(CNN) — 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 ...

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 ...

The wheel of time isn’t turning like it used to. Scientists have discovered that our planet’s core has been rotating at a slower rate for nearly 15 years — and it could mean longer days for some. The ...
