Shadow at Moon's South Pole

Caption

At the Moon’s poles and with the Sun at such a low angle, sunlight never reaches the floors of some deep craters. These PSRs are some of the coldest spots in the solar system, trapping volatile chemicals including water ice. New research indicates these regions are not as old as originally thought, so current estimates of water ice on the Moon may be too high.
