Images have revealed a hole on the Moon’s surface that is at least 260 feet deep and may lead to an underground tunnel more than 1,200 feet wide which is part of an entire network of such winding tubes.
Scientists are hoping for clearer shots from NASA’s Lunar Reconnaissance Orbiter, but the impression so far is that such a tunnel network could provide shelter for astronauts or potential future Moon colonists. I just plain wonder if they could combine it with the recent discovery of water for one kickass underground waterpark. [New Scientist via Pop Sci]
