In 2010, an analysis of Hubble images revealed a mottled world of orange, white, and black. The center held a mysterious bright spot, prompting NASA to time the New Horizons mission for a better view of the area, now seen as a heart shape.
Snapped July 8, 2015, this portrait shows the contrasting colors of Pluto (right) and its moon Charon. Pluto is a coppery, while Charon is a dull gray—just one reason scientists are surprised by how very different these two little worlds are.
Taken July 9, 2015, this black-and-white view of Pluto shows the "tail" of an immense black whale shape near the equator. Some scientists initially, and informally, dubbed the whale Cthulhu, after H.P. Lovecraft's character: part man, part dragon, part octopus.
On its final approach, New Horizons sent home this image on July 11, 2015. Surface features on Pluto are becoming more obvious at this point, with signs of craters and polygon-shaped regions that invite speculation. What do you see?
