Forget a doomsday asteroid or melting permafrost. It’s the freezing of Earth’s core that will end the world in today’s ...

New research suggests that Earth’s solid inner core might not be as rigid as once believed. Instead, it could exist in an ...

A bullet-speed experiment reveals that the Earth's inner core may be softer and more dynamic than previously thought.

New research suggests that the Earth's solid inner core is softer and more dynamic than previously thought, changing ideas.

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, ...

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 core cannot be made just of iron — it also appears to contain carbon. And our research suggests it may contain a bit of oxygen and possibly silicon as well. When you purchase through links on ...

One of the strangest mysteries about our Earth is the presence of two dense, giant blobs inexplicably clustered above the planet's core. "These are not random oddities," says geodynamicist Yoshinori ...

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 ...

Two enormous structures that sit at the border between the Earth’s mantle and its core have puzzled scientists for decades, defying reigning theories of how our planet came to be. In a new study ...

A team of geophysicists say that an enormous mass shifted deep beneath the Earth’s surface 18 years ago. As detailed in a paper published in the journal Geophysical Research Letters last month, a team ...
