As much as 45 oceans’ worth of hydrogen may be in Earth’s core, scientists reported, suggesting most of Earth’s water was ...

Deep below the crust and mantle, far beyond the reach of any drill, Earth’s core may be hiding a planetary-scale cache of ...

Earth’s core isn’t just a boring, featureless ball of metal, it turns out. A recent study used seismic waves from earthquakes to make a 3D model of the center of our planet, and the researchers ...

Scientists have long thought Earth's inner core is like a huge solid metal ball. But an experiment revealed it may be a lot softer — more like butter, a lead scientist said. It could help explain why ...

Earth’s magnetic field can linger in a weakened, unstable state for tens of thousands of years before fully flipping.

Researchers have discovered a new, innermost layer nestled inside our planet’s inner core, a 400-miles solid metallic ball that responds to the reverberating shockwaves of earthquakes in an unexpected ...

Measurements of seismic waves over many years suggest the Earth's core is deformed and reshaped by conditions of extreme heat ...

Around 1,800 miles beneath your feet lies a giant, blazing-hot ball of metal. It's the innermost part of our planet, Earth's core. It has a profound impact on your life, though none of us can even ...
