Understanding the boundary between Earth's rock mantle and the molten core is one of the key challenges in geoscience. In his Perspective, Garnero discusses recent geophysical discoveries that are forcing the adoption of a new paradigm for studying the core-mantle boundary. Long thought to be a simple division between solid silicate rock and liquid iron alloy, the core-mantle boundary is now emerging as an active, complex, and heterogeneous region of Earth's interior.
