There may be hidden layers to Earth’s core dictated by chemical composition. In A Nutshell Lab experiments suggest Earth’s ...

Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional ...

The Earth’s inner core, predominantly composed of iron with a minor admixture of nickel and light elements, is a critical component in understanding our planet’s magnetic field and thermal evolution.

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 ...

Cross-sectional illustration of Earth's layers, down to molten core. Scientists in China recently made a discovery at the heart of our planet: Every 8.5 years, the Earth's inner core wobbles around ...

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 ...

The Earth’s inner core, a solid sphere predominantly composed of iron and nickel, occupies a central role in our planet’s evolution and geodynamo processes. Although hidden beneath thousands of ...

Cartoon of the Earth with cutaway showing the mantle and inner and outer core. Magnetic field lines produced by the geodynamo extend into space and interact with the solar wind. The iron-rich core at ...

What is the speed and timing of the Earth’s inner core cooling? This is what a recent study published in Nature Communications hopes to address as a team of scientists investigated the composition ...

Though Earth's innermost core is solid, new research suggests that it hosts a lot of variation. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

Scientists have uncovered a previously unknown doughnut-shaped region within Earth's outer core, offering new insights into the dynamics of the planet's magnetic field. Located thousands of kilometers ...

Earth's core isn't exactly aligned with its mantle, which results in a cyclical wobble, new research finds. When you purchase through links on our site, we may earn an affiliate commission. Here’s how ...
