What: A shot of Buzz Aldrin standing on the surface of the moon snapped by Neil Armstrong, via NASA
Why: Early space photography meets the casual snapshot. Plus it also has the distinction of being one of the very first ever selfies in space — Aldrin captured his own image in the reflection of Armstrong's visor.
