A research team has produced the first direct experimental evidence that Earth’s iron core traps hydrogen inside nanoscale ...

Earth’s magnetic shield is shifting in dramatic ways. New data from ESA’s Swarm satellites show that the South Atlantic Anomaly — a vast weak spot in Earth’s magnetic field — has grown by nearly half ...

First ever supercomputer simulations of Mars with a fully molten core could explain the Red Planet's unusual magnetic field. Billions of years ago, Mars had an active magnetic field. Mysteriously, its ...

Gold and other precious metals are leaking from Earth’s core into the layers above, eventually making their way up to the surface during the formation of volcanic islands like Hawaii, a new study ...

Deep under the crust and mantle of our Earth lies its core. Earth’s core was formed during the Iron Catastrophe, a major geological event where Earth was heated to temperatures above iron’s melting ...
