These chemical oddities may explain why Earth seems to be deficient in certain elements — and could prove useful in catalysts ...

Earth's inner core is solid and blistering hot. For decades, scientists have known the inner core is solid thanks to the pioneering work of Danish seismologist Inge Lehmann, who first proposed its ...

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

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 ...

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

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 ...

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 ...

New research suggests that the Earth's solid inner core is softer and more dynamic than previously thought, changing ideas.

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 ...

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 ...
