A bullet-speed experiment reveals that the Earth's inner core may be softer and more dynamic than previously thought.

New research suggests that Earth’s solid inner core might not be as rigid as once believed. Instead, it could exist in an ...

Deep beneath our feet, approximately 2,890 kilometers underground, lies one of Earth's most mysterious regions. The boundary between our planet's molten outer core and solid mantle acts like a massive ...

The inner core was discovered in 1936, and its size (about 20% of Earth's radius) is one of the best-constrained properties of the deep Earth. We use this information to estimate the core's ...

Earth’s inner core has both changed its relative rotation rate and deformed in the past few decades, according to an analysis of seismic waves recorded when the inner core occupied the same relative ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. Now, a new study seeking to explain anomalous data suggests Earth's core may be layered like an onion. Scientists in Germany ...

Deep beneath our feet, at a staggering depth of over 5,100km, lies Earth's inner core — a solid ball of iron and nickel that plays a crucial role in shaping the conditions we experience on the surface ...

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 discovery that helium and iron can mix at the temperatures and pressures found at the center of Earth could settle a long-standing debate over how our planet formed. When you purchase through ...
