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

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

A wealth of new information about Earth’s inner core has surfaced in recent months. Scientists now have evidence that the planet’s innermost layer is changing shape. Scientists who just months ago ...

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

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 ...

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

Earth cross section showing the classic distinction between crust, mantle and core. But new research shows Earth's structure is far more complicated and may change over time. Analyzing an unusual ...

Geophysicists from ETH Zurich and SUSTech, China, have demonstrated the dynamo effect of the Earth’s core in a model in which viscosity has no influence, as is the correct physical regime for the ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. Earth’s core is pretty dynamic. Its spin speeds up and slows down ...

Earth's core cannot be made just of iron — it also appears to contain carbon. And our research suggests it may contain a bit of oxygen and possibly silicon as well. When you purchase through links on ...
