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 ...

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 ...

About 1,800 miles beneath the surface, Earth’s internal structure changes abruptly where the solid rock of the mantle meets the swirling molten iron of the outer core. But the boundary between the ...

Picture all of Earth’s oceans, which cover about 70% of the planet and are mostly made of hydrogen. Now multiply that by nine. That may be the amount of hydrogen in Earth’s core, possibly making it ...

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.

Add Yahoo as a preferred source to see more of our stories on Google. An artist's depiction of an asteroid hitting Earth. In recent research published by myself and my colleague Tony Yeates in the ...

When we look at the solid ground beneath our feet, it's easy to assume Earth has always been this way. But our planet tells a story so extraordinary, so ...
