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 ...

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 ...

Researchers have long struggled to explain how Earth’s solid inner core formed, cooled, and crystallized without undergoing extreme supercooling. But a recent study published in Nature ...

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 ...

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 ...

Russell has a PhD in the history of medicine, violence, and colonialism. His research has explored topics including ethics, science governance, and medical involvement in violent contexts. Russell has ...

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 ...

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 ...

An international research team may have found an explanation for seismic anomalies, the noticeable deviations in the behavior of earthquake waves, in Earth's inner core. A team led by scientists from ...

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 ...
