The Moon rotates in sync with its orbit, so Earth usually sees the same near side. NASA’s October 10 image shows the far side in a mosaic of more than 15,000 spacecraft frames, revealing a heavily cratered landscape unlike the smooth dark maria we know.

The highest-resolution version shows features at roughly 100 meters per pixel. It is an easy visual rabbit hole for anyone who enjoys photography, maps or geology.

Action: zoom into one cratered region and compare it with a near-side lunar image.
