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

The continent-sized blobs are much hotter than the lower mantle, creating a significant temperature gradient in the rocky ...

The blobs lie at the base of Earth’s mantle, around 1,802 miles beneath Africa and the Pacific.

Deep inside Earth is a solid metal ball that rotates independently of our spinning planet, like a top whirling around inside a bigger top, shrouded in mystery. This inner core has intrigued ...

Stanford researchers have created the first-ever global map of a rare earthquake type that occurs not in Earth's crust but in ...

For the first time, scientists have directly measured the amount of heat flowing from the molten metal of Earth’s core into a region at the base of the mantle, a process that helps drive both the ...

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 ...

Scientists have uncovered a previously unknown doughnut-shaped region within Earth's outer core, offering new insights into the dynamics of the planet's magnetic field. Located thousands of kilometers ...

The Earth’s inner core, a solid sphere predominantly composed of iron and nickel, occupies a central role in our planet’s evolution and geodynamo processes. Although hidden beneath thousands of ...

Southwest Research Institute’s Dr. Simone Marchi collaborated on a new study finding the first geophysically plausible scenario to explain the abundance of certain precious metals — including gold and ...
