Moon cave!  MAR 08 2011

Indian lunar orbiter Chandrayaan-1 has discovered a large cave on the Moon. Aside from the hey, cool, there's a cave on the Moon factor, the other big feature of the cave is its constant and temperate temperature.

Temperatures on the moon swing wildly, from a maximum of 262 degrees Fahrenheit to a minimum of -292. The cave holds steady at a (relatively) comfortable -4, since the moon's weather can't penetrate its 40-foot-thick wall. It could also protect astronauts from "hazardous radiations, micro-meteoritic impacts," and dust storms, according to paper published by the journal Current Science.
