For decades, Earth has been understood to have four main layers: the crust, mantle, outer core ... Despite this, the study is a major step forward in understanding the mysteries of Earth’s interior.

Mars spacecraft teamed up with an AI model to find a new impact crater on on the Martian surface, changing our understanding of the interior.

No one can see inside the Earth or drill deep enough to collect rock samples from the mantle—the layer between Earth’s core and its outermost rigid layer ... By measuring how fast these waves travel ...

While most of us take the ground beneath our feet for granted, written within its complex layers, like the pages of a book, is Earth's history. Our history. Research shows there are little-known ...

New measurements suggest mysterious continent-sized masses in our planet’s lower mantle may be extremely stable features ...
