A new report from a team of researchers at Texas Tech suggests humans may have inadvertently given the moon a fever because we were a little too messy during our Apollo visits.

NASA conducted a heat monitoring experiment on landing sites 15 and 17 between 1971 and 1972. During that time, it noted the temperature of the area increased by four degrees Fahrenheit. The mystery has bugged lunar observers for decades.
