NASA is making the first ever temperature map of the moon. They found that at the moon's south pole, it's colder than far away Pluto. The area is inside craters that are permanently shadowed so they never see sun.
Temperatures there were measured at 238degC below zero. That's just 2degC higher than the lowest temperature possible.
It is also about a degree chillier than what's been found on Pluto.
The information is from NASA's Lunar Reconnaissance Orbiter which started its science mission last week.
