Scientists have discovered a deep hole on the moon’s surface that might make a perfect spot for a future colony. The enormous hole is located in the moon’s volcanic Marius Hills region. The hole is 213 feet wide and 260 feet deep.
Most importantly, a thin sheet of lava protects the hole from meteorite strikes and harsh temperatures. Classified as a “lava tube,” this hole was discovered by a Japanese moon orbiter called SELENE and appears to be stable.
