In the northwestern region of Pluto’s Sputnik Planum, swirl-shaped patterns of light and dark suggest that a surface layer of exotic ices has flowed around obstacles and into depressions, much like glaciers on Earth. This is evidence for geologically recent surface activity. Credit: NASA/JHUAPL/SWRI
