Moon's south pole
lunar south pole images with element composition and temperature chart
Temperature charted in kelvin (K). Zero K, absolute zero, the absense of all heat, corresponds to -273.15 Celsius (C).

After announcing the discovery of water molecules on the moon, scientists have revealed new data uncovered by NASA's Lunar CRater Observation and Sensing Satellite, or LCROSS, and Lunar Reconnaissance Orbiter, or LRO—and it's more than just water. The above surface temperature map of the lunar south pole made by LRO's Diviner Lunar Radiometer Experiment . The map contains several intensely cold impact craters that could trap water ice and other icy compounds commonly observed in comets. The approximate maximum temperatures at which these compounds would be frozen in place for more than a billion years are noted on the right.
