According to the prevailing theory of how the Moon formed, it all began roughly 4.5 billion years ago when a Mars-sized object (Theia) collided with a primordial Earth. This caused both bodies to become a molten mass that eventually coalesced to form the Earth-Moon System (aka. The Giant Impact Hypothesis. This theory also states that the Moon gradually cooled from the top down, with the crust solidifying and arresting lava flows early in its history. However, recent findings from samples obtained by China's Chiang'e-5 probe indicate that lava existed at shallower depths longer than previously thought.

AI Uncovers Subsurface Entrances on the Moon
How can artificial intelligence (AI) be used to locate lunar pits and skylights, which are surface depressions and openings, respectively, that serve as entrances to lava caves and lava tubes? This is what a recent study published in Icarus hopes to address as an international team of researchers investigated using machine learning algorithms to more efficiently identify pits and skylights on lunar volcanic regions (lunar maria) of the Moon. This study has the potential to help researchers develop new methods in identifying key surface features on planetary bodies that could aid in both robotic and human exploration.
