The inner core of the Earth, which is found about 3,000 miles (4,828 kilometers) under the surface, sits within a molten outer core, and is anchored by gravity. Once commonly thought of as a solid ...

Earth's inner core is filled with a rare material known as 'extreme hydrogen', a study has claimed. This bizarre substance, known as super–ionic hydrogen, behaves unlike anything found on the surface.

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 ...

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 ...

While Earth's core consists mostly of iron, its density implies that lighter elements are also mixed in. Because hydrogen is abundant in the universe and can mix with iron under certain conditions, ...

Earth's molten outer core is critical to life on our planet. Churning some 2,900 kilometers beneath the surface, it's a vast "sea" of liquid iron that swirls around the planet's solid inner core. This ...

LOS ANGELES — USC scientists have made a groundbreaking discovery about the nature of the Earth’s enigmatic inner core, revealing for the first time that this 1,500-mile-wide ball of iron and nickel ...
