Deep Magma Oceans Could Help Make Super-Earths Habitable

This artist's illustration shows a super-Earth with deep layers of molten rock. New research shows that basal magma oceans on super-Earths could create the same kind of protective magnetic shield that Earth's core creates. Earth's shield is critical to its habitability, and these magma oceans on super-Earth's could also aid habitability. Image Credit: ESA/Hubble, M. Kornmesser

Deep beneath the surface of distant exoplanets known as super-Earths, oceans of molten rock may be doing something extraordinary: powering magnetic fields strong enough to shield entire planets from dangerous cosmic radiation and other harmful high-energy particles.
