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

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

USC scientists have made a groundbreaking discovery about the nature of Earth's enigmatic inner core, revealing for the first time that this 1,500-mile-wide ball of iron and nickel is changing. The ...

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

Earth’s inner core, a solid metal ball gyrating within the molten outer core, may be both slowing down and changing shape. Recent analyses of earthquake waves have suggested that around 15 years ago, ...

Buried more than 3,000 miles beneath our feet, Earth’s solid inner core was once thought to be unchanging—locked in place at the heart of the planet. But new research has revealed something much more ...

The surface of the Earth’s inner core may be changing, as shown by a new study from USC scientists that detected structural changes near the planet’s center, published Monday in Nature Geoscience. The ...

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 ...

Earth's inner core, the solid iron-rich mass at the center of our planet, is slowly growing as the surrounding molten outer core cools and freezes. But this process has been a source of debate amongst ...

The Earth’s inner core, predominantly composed of iron with a minor admixture of nickel and light elements, is a critical component in understanding our planet’s magnetic field and thermal evolution.
