   Explanation: A photograph of Buzz Aldrin standing on the Moon taken by
   Neil Armstrong, was digitally reversed to create this lunar selfie.
   Captured in July 1969 following the Apollo 11 moon landing, Armstrong's
   original photograph recorded not only the magnificent desolation of an
   unfamiliar world, but Armstrong himself reflected in Aldrin's curved
   visor. In the unwrapped image, the spherical distortion of the
   reflection in Aldrin's helmet has been reversed. The transformed view
   features Armstrong himself from Aldrin's perspective. Since Armstrong
   took the original picture, today the image represents a fifty-four year
   old lunar selfie. Aldrin's visor reflection in the original image
   appears here on the left. Bright (but distorted) planet Earth hangs in
   the lunar sky above Armstrong's figure, toward the upper right. A
   foil-wrapped leg of the Eagle lander and Aldrin's long shadow
   stretching across the lunar surface are prominently visible. In 2024
   NASA's Artemis II mission will return humans to the Moon.
