A new study provides the best evidence yet for a hidden layer deep within Earth’s solid inner core.
Earth’s inner core, made of solid iron and nickel, is roughly two-thirds the size of the moon.
The researchers used machine learning to pinpoint the most accurate model of the strange physical processes that shape our planet's inner core.
Earth’s core is a strange, strange place. For decades, scientists have suspected that, like Matryoshka stacking dolls, there may be an additional hidden layer within our planet’s solid iron and nickel inner core.
