Scientists combined computer simulations and spacecraft data to solve a long-standing mystery surrounding the moon’s ‘lopsided’ geology

Linking analyses of the moon’s gravity field with models of its earliest evolution, scientists tell a story of the moon turning itself inside out after it solidified from a primordial magma ocean. The process left behind a vestige of dense, titanium-rich material beneath its Earth-facing side that makes its presence known by gravity anomalies.
