New research into Earth’s inner core suggests that supercooling, a process where a liquid cools below its freezing point without solidifying, may reveal that the core is much younger than previously thought. Composed of iron and nickel, the core plays a critical role in maintaining Earth’s magnetic field, which protects the planet from harmful solar radiation.
