Research suggests some metals’ semicore electrons may be more active on Earth’s surface than previously thought.

Earth's mantle is a restless, enigmatic engine that powers volcanism, recycles crust, and regulates the long-term evolution ...

Mars is not the pristine, stratified world that people once imagined it is a graveyard of shattered worlds, their shattered remnants encapsulated deep in its mantle for over four billion years. It is ...

Scientists detect a solid inner core on Mars for the first time, revealing a new chapter in planetary evolution.

Two recent studies used seismic data from NASA's retired InSight mission to shed light on what lies beneath Mars’ surface and ...
