Scientists discover six hidden structures at Earth's core-mantle boundary

Scientists have identified six mysterious structures deep beneath Earth's surface at the core-mantle boundary, a discovery that challenges existing models of the planet's interior dynamics. Using artificial intelligence to analyze over two million seismic records, researchers detected 174,929 faint signals, revealing these large regions with strong seismic scattering. The structures may be remnants of a primordial magma ocean, altered by core interactions over billions of years. The findings suggest these anomalies could include fragments of ancient subducted plates, chemical segregations, or zones of localized melting, offering new insights into Earth's deep evolution and the processes shaping its internal machinery.
