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 ...

An international research team may have found an explanation for seismic anomalies, the noticeable deviations in the behavior of earthquake waves, in Earth's inner core. A team led by scientists from ...

A battle of forces, driven by the motion of Earth’s core, can explain small variations in the planet’s rotation, study finds.

Researchers from China discovered that the Earth's inner core is divided into an upper inner core and a lower inner core, and that the crystal alignment differs in the two sections. - Provided by ...

Tiny changes in Earth’s rotation may reveal a tug-of-war between its deformable inner core, liquid outer core and deep mantle.

The new map highlights six regions that had been poorly sampled by PKP precursor studies and now appear to be promising targets for closer investigation. They include areas beneath high-latitude ...

Earth's core: solid or liquid? Yes — we know more about distant galaxies than our own interior. Is Earth's core solid or liquid? Yes. Our planet's interior has been harder to study than the cosmos. We ...

What the research is about Earth's inner core is thought to consist mainly of iron, yet many questions remain about its ...

The inner core of Earth is the planet’s solid, innermost region, composed primarily of iron with minor nickel and light elements, extending from about 1,220 km radius to the center. It is ...
