Needle in a Haystack

This visualization shows a newly-discovered dwarf planet, “DeeDee” as it appears in the sky through three years of surveys by the Dark Energy Camera. ¬†Each grey pixel is an object that was spotted on one night – the red dots are the points that were sifted out of this information and analyzed to confirm DeeDee’s position and orbit.

The data was imported into R and built into this animation using ggplot2 and gganimate.
