A few things inhibit a full-time, human-populated base on the moon: micrometeorites, intense surface radiation and crazy temperature swings (from 100°C/212°F days into -173°C/-280°F nights). Japanese scientists from the Japan Aerospace Exploration Agency believe they have discovered something that can solve this: a massive cave (potentially once a lava tube) just below surface level. At 31 miles long and 330 feet wide, the space now known as the Marius Hills hints at a future quite like a science fiction novel. Before anything further can happen, scientists do need to conduct far more research and see additional imagery from the ground. Read more at Quartz.
