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 ...

Deep beneath our feet, far beyond the reach of any drill, new research suggests that Earth’s center is far more intricate ...

A new study offers compelling evidence that Earth's inner core reversed direction and is slowing down.

Earth’s inner core has long puzzled scientists because seismic waves move through it unevenly. Compressional waves from ...

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, ...

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 ...

Earth's inner core, the solid iron-rich mass at the center of our planet, is slowly growing as the surrounding molten outer core cools and freezes. But this process has been a source of debate amongst ...

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 ...

Alfred Wilson-Spencer receives funding from the Natural Environment Research Council (NERC) grants NE/T000228/1 and NE/V010867/1. He works for the University of Leeds. The iron-rich core at the centre ...
