Pluto's surface looks pretty textured even from afar, but you may still be surprised by how complex its terrain actually is. This new color-coded geological map illustrates that complexity more clearly. It covers 1,290 miles of the dwarf planet, including the left side of Pluto's heart-shaped region and its surrounding areas. NASA has identified and labeled the texture and morphology of everything that falls within the rectangular map. The cracked, bluish part in the center, for instance, represents a nitrogen ice plain within Tombaugh Regio called Sputnik Planum.
