New research suggests that Earth’s solid inner core might not be as rigid as once believed. Instead, it could exist in an ...

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 ...

More insights about Earth's core have arrived through some detailed examinations. A team of researchers believes that the inner core is made of two distinct layers. The finding has been explained in ...

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

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 ...

New research suggests that the Earth's solid inner core is softer and more dynamic than previously thought, changing ideas.

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 ...

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 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 ...

Earth’s core, the deepest part of our planet, is characterized by extremely high pressure and temperature. It is composed of a liquid outer core and solid inner core. The inner core is formed and ...
