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 ...

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 ...

Deep beneath our feet lies one of the most important parts of our planet: Earth’s core. Hidden thousands of kilometers below the surface, this massive sphere is made primarily of iron and nickel. At ...

A surprising discovery beneath the Pacific Ocean reveals that Earth's molten outer core has reversed its flow direction, ...

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 ...

Earth’s inner core is believed to consist of an iron–light-element alloy such as iron hydride (FeH X). The possibility that a superionic state may emerge in the inner core has recently gained ...

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 ...

All the activity on Earth’s surface — erupting volcanoes, shifting tectonic plates, restless seas and myriad forms of life — depends on the two-part engine under the hood. Directly beneath Earth’s ...

The liquid iron in Earth's outer core doesn't always behave as expected. When it changed direction in an unexplained way, ESA satellites provided data on the direction of flow, helping scientists gain ...

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 ...
