Shadows & water? Because the Sun is at a low angle, sunlight never reaches the floors of some craters. These permanently shadowed regions are some of the coldest measured spots in our solar system, like -416 degrees F (-249 C) cold. So cold that water in them can't escape. https://t.co/9Sk4VMXmHU #Photography
