Earth’s deep interior still shapes the world above your feet. Water trapped far below the surface helps control how rocks ...

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 ...

Earth's deep mantle stored enough water in rocks to equal one ocean during our planet's early molten days, helping explain ...

A new study offers compelling evidence that Earth's inner core reversed direction and is slowing down.

In 2019, scientists detected a strange wobble deep below the Earth’s surface that oscillates roughly every 8.5 years. Now, by mapping minute changes in the Earth’s rotation, the team has come up with ...

Far beneath Earth’s surface, two enormous structures lie hidden at the edge of the planet’s molten core. These formations, each thousands of kilometers wide, aren’t just geological oddities—they might ...

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 ...

Far below our feet, two colossal structures the size of continents sit atop Earth’s core, one beneath Africa and one beneath the Pacific Ocean. These dense, hot anomalies have puzzled geophysicists ...

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 ...
