| New images of the moon's surface taken from the Lunar Reconnaissance Orbiter Camera show fault lines with a surprising explanation: the moon may be shrinking. Writing in the journal Science, researchers describe the 'lobate scarps,' a type of thrust faults that occur primarily in the lunar highlands. Characteristics of the faults indicate that the moon has shrunk significantly in the recent past -- a change the researchers suspect is due to cooling of the moon. We'll talk about the research and what it might mean. |
