Moon's Geology Unveiled: Mantle Turned Inside Out Over 4 Billion Years Ago

New study combines simulations and spacecraft data to explain the moon's uneven distribution of titanium-rich volcanic rocks.

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.
