Oxygen is the key substance for life and one of the most abundant elements in the Earth. However, it’s still unknown whether oxygen is present and in which form in the inner core with extreme high ...

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 ...

In work that promises to advance understanding about the origin and dynamics of Earth’s iron-rich inner core and the generation of the planet’s magnetic field, a team that includes University of ...

The distance from the Earth's surface to its center is almost 4,000 miles—but our planet's structure is not uniform and is actually made up of several different layers, some of which are hotter than ...

Earth’s inner core is surprisingly soft, and wiggling iron atoms may help explain why. The innermost part of our planet is a solid iron ball smaller than the moon and almost as hot as the surface of ...

The iron-rich core at the centre 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, ...

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