   Explanation: [7]A photograph of Buzz Aldrin standing on the Moon taken
   by [8]Neil Armstrong, was digitally reversed to create this lunar
   selfie. Captured in July 1969 following the Apollo 11 moon landing,
   [9]Armstrong's original photograph recorded not only the
   [10]magnificent desolation of an [11]unfamiliar world, but Armstrong
   himself reflected in Aldrin's curved visor. In the [12]unwrapped image,
   the [13]spherical distortion of the reflection in Aldrin's helmet has
   been reversed. The transformed view features Armstrong himself [14]from
   Aldrin's perspective. Since Armstrong took the original picture, today
   the image [15]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 [16]Earth hangs in the lunar sky above
   Armstrong's figure, toward the upper right. A foil-wrapped leg of the
   [17]Eagle lander and Aldrin's long shadow stretching across the lunar
   surface are prominently visible. In 2024 [18]NASA's Artemis II mission
   will return humans to the Moon.
