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

Earth’s inner core has long challenged researchers because seismic waves do not move through it uniformly. Compressional waves generated by earthquakes travel roughly 3 to 4 percent faster along Earth ...

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 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, ...

Earth’s inner core has long puzzled scientists because seismic waves move through it unevenly. Compressional waves from earthquakes travel about 3 to 4 percent faster along the planet’s rotation axis ...

This video explains recent scientific findings about changes in Earth’s inner core rotation, what researchers measure, and ...

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 ...

New research reveals that Earth’s solid inner core is actually in a superionic state, where carbon atoms flow freely through a solid iron lattice. This unusual behavior makes the core soft, matching ...

CAPE CANAVERAL, Fla. — Scientists revealed this week that Mars’ innermost core appears to be a solid hunk of metal just like Earth’s. The Chinese-led research team based their findings on seismic ...

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 ...

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.

The Chinese-led research team based its findings on seismic readings from NASA's InSight lander on Mars, which recorded more than 1,300 marsquakes before shutting down in 2022. The spacecraft landed ...
