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

Earth's inner core is solid and blistering hot. For decades, scientists have known the inner core is solid thanks to the pioneering work of Danish seismologist Inge Lehmann, who first proposed its ...

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, ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. A wealth of new information about Earth’s inner core has surfaced in recent months. Scientists now have evidence that the planet’s ...

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 ...

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.

Earth's inner core is undergoing structural transformation. Located 3,000 miles below the Earth's surface, the inner core is anchored by gravity within the molten liquid outer core. Until now the ...

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 ...
