Scientists at Japan's space agency have discovered a huge moon cave that could one day house a base that would shelter astronauts from dangerous radiation and wild temperature swings, officials said Thursday. Data taken from Japan's SELENE lunar orbiter has confirmed the existence of the 50 kilometre (31 miles) long and 100 metre wide cavern that is believed to be lava tube created by volcanic activity about 3.5 billion years ago. The major finding was published this week in US science magazine Geophysical Research Letters.
