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

Can a movement many feet below our feet quietly change the Earth’s rotation? Over 3,000 miles below the ground, the Earth’s inner solid core a ball of iron and nickel whose temperature is as hot as ...

(NEXSTAR) – Deep in the center of the Earth is the inner core, which spans roughly 746 miles and is composed of primarily pure, solid iron, NASA explains. Though we’ve long believed – and research has ...

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, ...

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 Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

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 ...

Geophysicists from ETH Zurich and SUSTech, China, have demonstrated the dynamo effect of the Earth’s core in a model in which viscosity has no influence, as is the correct physical regime for the ...

Through molecular dynamics simulations of supercooled Fe–C liquids, we show that elevated x C can significantly reduce the supercooling requirement for nucleation to spontaneously occur. This expands ...

Earth, our home planet, is a world unlike any other. The third planet from the sun, Earth is the only place in the known universe confirmed to host life. With a radius of 3,959 miles, Earth is the ...

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 ...
