Earth's mantle is a restless, enigmatic engine that powers volcanism, recycles crust, and regulates the long-term evolution of the planet. But one of its most elusive characteristics—the redox state, or the balance of oxidized ...

The moon's nearside (that is, the side facing Earth) is dark-colored and dominated by ancient lava flows, whereas the farside is more rugged—and NASA researchers now suggest it's due to a wonky lunar interior. Using data ...

The mantle transition zone (MTZ), which occurs 410–670 kilometers below Earth's surface, may store several oceans' worth of water. This water, which is carried to such depths by subducting tectonic slabs, is stored in minerals ...
