The headline says it all: The list of our moon's craters just got a little longer.
On Nov. 13, the Lunar Reconnaissance Orbiter Camera (LROC) team — which operates visual equipment on NASA's Lunar Reconnaissance Orbiter (LRO) — announced the discovery of a never-before-seen dent in Earth's natural satellite. It appears to be about 72 feet (22 meters) in diameter, probably formed between December 2009 and December 2012 and comes from a collision scientists say happened just north of another lunar cavity, Römer crater.
