Deep inside Earth is a solid metal ball that rotates independently of our spinning planet, like a top whirling around inside a bigger top, shrouded in mystery. This inner core has intrigued ...

Seismic waves passing through the Earth have revealed that the inner core of our planet is now rotating out-of-sync with the layers above it. Update: As reported below, research from January 2023 ...

The inner Earth is a mysterious place, and now scientists may have uncovered a strange new secret. According to a new study, the Earth’s inner core may have recently stopped rotating, relative to the ...

The Earth's internal layers including the mantle, outer core and inner core. New research shows the inner core undergoes structural transformation likely caused by outer core disturbance. The surface ...

Using seismic waveform data, researchers believe they’ve discovered Earth’s even smaller inner core. The new inner core is made up of about 400 miles of dense iron, the researchers say. Seismic waves ...

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 ...

“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 ...

Earth’s core has long been a place of mystery to scientists. The core of our planet sits just over 1,800 miles below the surface and exists as a ball of seething hot metal, specifically iron and ...

LOS ANGELES — Scientists have just detected something unusual happening 3,000 miles beneath our feet. New research from an international study reveals that Earth’s inner core, a ball of mostly iron ...

The core is losing heat faster under Indonesia than it is under Brazil, and that's messing with the seismic waves passing through it. When you purchase through links on our site, we may earn an ...

Earth’s inner core may be made of fluid light elements swirling around amid a solid lattice of iron, according to a computer simulation study. A team of physicists recently modeled how alloys of iron ...

Mysteries still abound for scientists studying the Earth’s climate, biosphere, surface topography, and even the oceans, but they all have a distinct advantage: the subjects of their inquiries are, to ...
