By analyzing seismic waves from earthquakes from the 1960s, researchers from Peking University deduced that the Earth's inner ...

A new study of decades worth of seismogram data shows that the surface of Earth’s iron and nickel core is more malleable than scientists thought.

Scientists have identified another possible commonality between Earth and Mars: a solid inner core. Scientists have ...

Earth appears to be a chill blue planet, but deep down, it’s really a metalhead. Its outer core is mostly molten iron (and ...

The next layer is the mantle, which makes up most of Earth's volume and is composed of dense, semi-solid rock. Then there is the outer core, made of liquid metal, and the inner core, a solid ball ...

Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

Scientists have raised concerns that the Earth's inner core may completely halt its rotation by 2040, according to a recent paper published in Nature. The study suggests changes are occurring deep ...

The discovery that inert helium can form bonds with iron may reshape our understanding of Earth’s history. Researchers from ...

The findings confirm that helium could stay locked in Earth's solid inner core for a long time, Olson told Live Science, but he cautioned that only 4% of the core is solid. "This is significant ...

Scientists confirm the Moon has a solid iron core, like Earth’s, with a molten outer layer. This discovery reshapes our ...
