Our planet may have had a recent change of heart. Earth’s inner core may have temporarily stopped rotating relative to the mantle and surface, researchers report in the January 23 Nature Geoscience.

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

The rotation of Earth's inner core began to slow down more than a decade ago, altering the length of our days by fractions of a second. Researchers from the University of Southern California (USC) ...

No one knows why the river of liquid iron flowing 1,400 miles beneath our feet just reversed course.

The surface of Earth's inner core may be shape-shifting, new research suggests. The study, published Feb. 10 in the journal Nature, looked at earthquake waves that have skimmed the edge of the inner ...

Not only is Earth's inner core spinning and growing, but it's also changing shape, according to new research. Our planet's ...

The inner core of the Earth, which is found about 3,000 miles (4,828 kilometers) under the surface, sits within a molten outer core, and is anchored by gravity. Once commonly thought of as a solid ...

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 ...

Geophysicist John Vidale noticed something striking while tracking the way seismic waves move from Earth’s crust through its core. The very center of the planet, a solid ball of iron and nickel ...
