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.
Two words: giant space worms. Shut up, the giant is silent! But only while he sleeps. Kidding, he's a snorer! I'm not insane, you're insane! Plus a jerk.
