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 ...

PCWorld reports that scientists discovered Earth’s inner core has slowed its rotation relative to the crust, even appearing to stop moving in a phenomenon that occurs every 35 years. This iron-nickel ...

Through molecular dynamics simulations of supercooled Fe–C liquids, we show that elevated x C can significantly reduce the supercooling requirement for nucleation to spontaneously occur. This expands ...

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 making it ...
