When a NASA spacecraft passes over Shackleton Crater on the moon and peers in, it sees this: a sea of blackness and nothing more.
This 13-mile-wide crater lies close to the moon’s south pole.
Here, the sun never rises high above the horizon, and the rim of Shackleton blocks the sun’s rays from ever shining directly onto the crater floor.
Scientists have now figured out how to, in essence, flip on the light switch.
Here is what the inside of Shackleton Crater looks like.
