During the buildup to the big Pluto flyby in July, the team behind NASA’s New Horizons mission launched a campaign to show regular folks what time of day during earthly twilight was as bright as high noon on the dwarf planet – and asked them to send in their “Pluto Time” selfies. Now those pictures have been assembled into mosaics that show off the shades of Pluto and its largest moon, Charon.
If you look closely at the blown-up view of Pluto, you’ll find a bonus: a portrait of Clyde Tombaugh, the self-taught astronomer who discovered the dwarf planet in 1930.
