A massive, iron-rich structure sitting at the base of Earth’s mantle beneath the Hawaiian Islands may be doing more than ...

The beginnings of a strange layer of molten rock deep inside the Earth may have finally been figured out by geoscientists. This layer, known as the D" layer, is about 1,900 miles underneath the ...

A recent study in Nature Communications by scientists from China and Belgium suggests that Mercury's core-mantle boundary (CMB) includes a diamond layer, potentially up to 18 kilometers thick, deep ...

Deep within Earth, there lies a mysterious layer called the D" layer. Located roughly 3,000 kilometers down, this zone sits just above the boundary between the planet's molten outer core and its solid ...

Scientists now understand why seismic waves speed up near Earth's core. Extreme pressure and temperature cause solid mantle rock to flow slowly, aligning mineral crystals. This anisotropic structure ...

The flow of magma into a 15-kilometre-long crack ahead of the recent volcanic eruptions in Iceland occurred at the highest rate observed anywhere in the world for this kind of event. World's first ...
