The iron-rich core at the center of our planet has been a crucial part of Earth's evolution. The core not only powers the magnetic field which shields our atmosphere and oceans from solar radiation, ...

Scientists have long known that Earth's core is mostly made of iron, but the density is not high enough for it to be pure iron, meaning lighter elements exist in the core, as well. In particular, it's ...

Deep beneath our feet, something extraordinary is happening. Scientists have discovered that changes in Earth's core are directly influencing our planet's magnetic field in ways we're only beginning ...

Earth’s core may contain up to 45 oceans’ worth of hydrogen, a new study finds—an estimate that suggests that the planet formed from a gas-and-dust disk that was rich in the universe’s lightest ...

LONDON — Picture all of Earth's oceans, which cover about 70% of the planet and are mostly made of hydrogen. Now multiply that by nine. That may be the amount of hydrogen in Earth's core, possibly ...
