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 surface of Earth's inner core may be shape-shifting, new research suggests. The study, published Feb. 10 in the journal Nature, looked at earthquake waves that have skimmed the edge of the inner ...

The new research adds to the mysteries of the planet’s deepest interior region. By Kenneth Chang The inner core at the center of the Earth, a ball of iron and nickel about 1,500 miles wide, may not be ...

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 ...

Our Earth is structured sort of like an onion – it’s one layer after another. Starting from the top down, there’s the crust, which includes the surface you walk on; then farther down, the mantle, ...

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 ...

Deep at the center of the Earth, our planet’s inner core is spinning, growing and—according to new research—shape-shifting. A new study published Monday in the journal Nature Geoscience found evidence ...

We know the temperature of Earth ’s inner core is very roughly about 5,000 Kelvin (K) (4,727°C). It was once liquid, but has cooled and become solid over time, expanding outwards in the process. As it ...

Earth’s magnetic field protects the planet from space weather like cosmic radiation and charged particles from the Sun. The ...

When a Mars-sized meteorite slammed into Earth billions of years ago, the impact completely reset any and all chemical ...

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 ...
