Deep inside Earth, researchers see signs that the solid inner core may be arranged in multiple chemical layers far below.

New research reveals that Earth’s solid inner core is actually in a superionic state, where carbon atoms flow freely through ...

Earth’s inner core has long puzzled scientists because seismic waves move through it unevenly. Compressional waves from ...

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) ...

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 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 ...

A new study offers compelling evidence that Earth's inner core reversed direction and is slowing down.

Scientists who just months ago confirmed that Earth's inner core recently reversed its spin have a new revelation about our planet's deepest secrets — they identified changes to the inner core's shape ...

An international research team may have found an explanation for seismic anomalies, the noticeable deviations in the behavior ...

Deep beneath our feet, far beyond the reach of drills or submersibles, Earth hides a solid metal heart that behaves in ways geophysicists have struggled to explain. New experiments now suggest that a ...
