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

Measurements of seismic waves over many years suggest the Earth's core is deformed and reshaped by conditions of extreme heat ...

Earth's solid inner core has begun to slow its rotation relative to the surface, a shift detected through seismic data. This ...

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 ...

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, ...

An analysis of seismic waves propagating through Mars finds evidence that the planet has a small, solid inner core, which challenges existing planetary models. Read the paper: Seismic detection of a ...
