A team of scientists from CNRS, University of the Cote d’Azur, Cote d’Azur Observatory, Sorbonne University, and Paris Observatory-PSL has discovered a solid core at the center of the Moon, similar to Earth’s. The researchers used data from various space missions and lunar laser ranging to confirm the existence of the solid inner core, which has a diameter of around 500 km and comprises roughly 15% of the Moon’s total size. The team also found evidence supporting the lunar mantle overturn hypothesis, which suggests that material movement occurred within the mantle during the Moon’s evolution. This phenomenon helps explain the presence of iron-rich elements on the lunar surface. The research offers valuable insights into the history of the solar system and events such as the disappearance of the lunar magnetic field.
