Earth's inner core, once rotating faster than the surface, has begun to slow, impacting day length by fractions of a second. This subtle shift, detected through seismic wave analysis, reveals complex ...

For years, scientists have tried to understand what’s hidden in the Earth. Now, a recent investigation has revealed something surprising: the Earth’s core ...

To understand the mantle—the largest layer of Earth’s rocky body—scientists drill deep cores out of the Earth. Scientists drilled the deepest core yet and recovered serpentinized peridotite that forms ...

A research team has produced the first direct experimental evidence that Earth’s iron core traps hydrogen inside nanoscale ...

Scientists discovered plate anomalies in Earth's mantle using seismic wave analysis. These mysterious structures challenge tectonic theories.

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

Scientists at Stanford have unveiled the first-ever global map of rare earthquakes that rumble deep within Earth’s mantle rather than its crust. Long debated and notoriously difficult to confirm, ...
