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 ...
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) ...
University of Southern California scientists have proven that the Earth's inner core is backtracking—slowing down—in relation to the planet's surface, as shown in new research published in Nature.

New discovery unlocks secrets of Earth’s inner core
The iron-rich core at the centre of our planet has been a crucial part of Earth’s evolution. The core not only powers the magnetic field which shields our atmosphere and oceans from solar radiation, ...
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 ...
Decades worth of seismic data confirms the rotation of Earth's inner core is moving slower than the planet's surface. When you purchase through links on our site, we may earn an affiliate commission.
