Elusive ‘Geoneutrinos’ Are Building a New Map of Earth’s Volatile Interior

A global network of detectors is reporting substantial measurements of geoneutrinos, particles created deep underground by radioactive elements that power Earth's tectonic activity. These elusive particles are helping scientists build a new map of Earth's volatile interior, revealing how radioactive decay drives plate movement and mantle convection. The findings mark a significant advance in understanding the planet's internal heat sources and geological dynamics.
