NASA's Lunar Reconnaissance Orbiter has recently uncovered what could be the deepest known cave on the moon, located in Mare Tranquillitatis. This cave features a 330 feet (100 meters) wide 'skylight' entrance, making it a fascinating discovery for potential future lunar exploration.
Researchers at the University of Trento in Italy have shed light on the Mare Tranquillitatis Pit in a paper published in Nature Astronomy. This pit is one of approximately 200 similar features on the moon, known as pits, which could potentially lead to caves or lava tubes. Pits are believed to form when sections of a lava tube's ceiling collapse, with some directly exposing the interior, known as skylights.
