Time is relative. The ticking of the clock, even of the most precise clocks we can make, does not exist in an absolute. It ...

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 Earth's magnetic field and oxygen evolved together over 540 million years, according to a major NASA study.

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

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

A study by researchers at the University of Oxford, University of Leeds, and University College London has identified a new constraint on the chemistry of Earth's core, by showing how it was able to ...

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, ...

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 ...

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

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.

Gold and other precious metals are leaking from Earth’s core into the layers above, eventually making their way up to the surface during the formation of volcanic islands like Hawaii, a new study ...
