ESA satellites detected a dramatic reversal in Earth’s molten core flow beneath the Pacific, revealing unexpected changes ...

Earth’s molten outer core is critical to life on our planet. Churning some 2,900 kilometers beneath the surface, it’s a vast ...

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 ...

The iron-rich core at the center 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 liquid iron in Earth's outer core doesn't always behave as expected. When it changed direction in an unexplained way, ESA ...

(CNN) — 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 ...

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 solid inner core at the center of the Earth, surrounded by the outer core, mantle and crust. Here’s why: While it is well known that a material must be at or below its freezing temperature to be ...

This video explains recent scientific findings about changes in Earth’s inner core rotation, what researchers measure, and ...

Earth’s core, the deepest part of our planet, is characterized by extremely high pressure and temperature. It is composed of a liquid outer core and solid inner core. The inner core is formed and ...

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 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 ...
