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.

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, ...

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 ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. Earth’s core is pretty dynamic. Its spin speeds up and slows ...

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 ...

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 ...

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.

Alfred Wilson-Spencer receives funding from NERC grants NE/T000228/1 and NE/V010867/1. Deep beneath our feet, at a staggering depth of over 5,100km, lies Earth’s inner core — a solid ball of iron and ...

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 ...
