Scientists believe that Earth's core is a massive ball of iron. However, a new discovery suggests that the Earth's core is surrounded by an unexpected ancient structure. A high-resolution map of the ...

For generations, scientists have probed the structure and composition of the planet using seismic wave studies. This consists of measuring shock waves caused by earthquakes as they penetrate and pass ...

The bulk elemental composition of Earth can’t be fully explained by compositional differences in its initial building blocks, according to a new study by Paul Frossard and colleagues. Instead, they ...

Earth’s surface environment hosts large reservoirs of hydrogen (H, mainly in the form of water, H2O), nitrogen (in atmospheric N2) and carbon (mainly in carbonate rocks). H, N and C are sometimes ...

In work published in Science Advances, a team of researchers have determined a new pressure scale, which is critical for understanding the Earth’s composition. Using x-rays from a uniquely powerful ...

For decades, scientists have been baffled by two enormous, enigmatic structures buried deep inside Earth with features so vast and unusual that they defy conventional models of planetary evolution.
