A new study adds evidence to the idea that Earth's inner core is slowing its spin, though still rotating in the same direction as the planet. KATERYNA KON / SCIENCE PHOTO LIBRARY via Getty Images The ...

Beneath our feet lies a hidden world as mysterious as space itself, the Earth’s core. This distant interior region, more than 3,000 miles (5,000 km) beneath the surface, is out of reach of instruments ...

Deep beneath our feet, far beyond the reach of any drill, new research suggests that Earth’s center is far more intricate than a simple metal ball. Instead of a single solid sphere, the inner core ...

Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional waves generated by earthquakes travel roughly 3 to 4 percent faster along Earth ...

“It’s probably benign, but we don’t want to have things we don’t understand deep in the Earth.” Now, a recent study published in the scientific journal Nature Geoscience reveals a curious new detail ...

Scientists have long wondered what lies at the very center of the Earth, and the latest research is putting weight behind a theory that our planet has a distinct ball of iron within its metallic core.

Data captured from seismic waves caused by earthquakes has shed new light on the deepest parts of Earth’s inner core, according to seismologists from The Australian National University (ANU). By ...

(CNN) — The rotation of Earth’s inner core may have paused and it could even go into reverse, new research suggests. The Earth is formed of the crust, the mantle and the inner and outer cores. The ...
