Scientists Detect Strange New Structures Deep Inside the Earth

On Sept 5, 2026 researchers reported the detection of six anomalous formations at the core‑mantle boundary, the interface between Earth’s solid mantle and liquid outer core. The discovery emerged from seismic data processed through a deep‑learning algorithm that flagged patterns inconsistent with known mantle structures.

The timing follows a surge in high‑resolution global seismograph networks, enabling the new analysis. Lead investigators say the features appear as localized velocity anomalies, suggesting distinct compositional or thermal properties.

Phys.org and IFLScience cite the deep‑learning model’s cross‑validation with independent seismic stations as proof of the structures’ reality, while Futurism notes the find challenges conventional models of core‑mantle dynamics. Coverage does not yet specify the formations’ composition, potential impact on geomagnetic processes, or whether they are stable over geological time.
