Overview

• University of Arizona scientists reveal the moon's 'lopsided' geology was caused by its mantle turning inside out over 4 billion years ago.
• Research combines computer simulations and spacecraft data, including NASA's GRAIL mission, to trace the migration and sinking of titanium-rich material.
• This dense material's movement created gravitational anomalies, explaining the concentration of titanium-rich volcanic rocks on the moon's nearside.
• The findings challenge previous models and offer new insights into the moon's geologic evolution, with implications for Earth and other planets.
• Future lunar missions could further explore the moon's interior structure, enhancing our understanding of its early evolution.
