Understanding inner core oscillations is key to grasping Earth's rotation variations and magnetic field changes, linking deep processes to surface effects.

A research team has produced the first direct experimental evidence that Earth’s iron core traps hydrogen inside nanoscale ...

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 ...

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 ...

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 ...

Earth's solid inner core has begun to slow its rotation relative to the surface, a shift detected through seismic data. This subtle change, occurring around 2010, may slightly alter the length of our ...

PCWorld reports that scientists discovered Earth’s inner core has slowed its rotation relative to the crust, even appearing to stop moving in a phenomenon that occurs every 35 years. This iron-nickel ...

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 ...

Precious metals may be escaping from the planet’s core. This hotly debated subject could help us understand Earth’s evolution and determine whether life exists elsewhere in the Universe ...
