Remains of planet that formed the Moon may be hiding near Earth’s core High-density material in the mantle may be remains of a Mars-sized planet.

An analysis of Hawaii’s volcanic rocks revealed Earth’s core is leaking gold and other precious metals, a study found. The elements emerge when ocean islands form.

Experts detect many heavy metals in the collected lava samples from Hawaii, which they believe arrived from 1,900 miles below ...

Rocky bodies called protoplanets were thought to have formed slightly earlier in the inner solar system than those beyond the ...

The record-breaking mission offers an unprecedented opportunity to study the geology of our planet’s largest layer.

A ‘ghost plume’ identified deep in the mantle beneath Oman suggests there may be more heat flowing out of Earth’s core than ...

A small, inconspicuous meteorite may be about to change our understanding of how and when our solar system formed. Tiny shavings from the meteorite Northwest Africa 12264 are challenging the long-held ...

Mantle plumes are important geologic processes—they interact with plate tectonics, create rich mineral deposits, and even ...

While it's unlikely the deep-buried treasure chest will ever be cracked open, scientists call the discovery significant.

An analysis of Hawaii’s volcanic rocks revealed Earth’s core is leaking gold and other precious metals, a study found. The elements emerge when ocean islands form.

The mantle is incredibly difficult to study because it’s so deeply buried beneath the Earth’s crust, or outer skin. Now, scientists have drilled a 1,268m-deep core that reaches down into this ...

The Earth’s interior is far more complex than what we are taught in school. Instead of just three layers- crust, mantle, and core- the Earth is made up of multiple intricate layers, each with ...
