Scientists have discovered a cave on the Moon that could serve as a potential refuge for future astronauts. Located in the Sea of Tranquility near the Apollo 11 landing site, the cave is reachable from the deepest known lunar pit and measures approximately 130 to 170 meters below the surface. This discovery is significant as it offers protection from extreme temperatures, cosmic radiation, and micrometeorite impacts, making it a safer alternative to surface habitats. Researchers used radar data from NASA's Lunar Reconnaissance Orbiter to map part of the cave, revealing its potential for both habitation and scientific study. The findings open new possibilities for establishing a permanent human presence on the Moon and contribute valuable insights into lunar geology.
