Backlit by the sun, atmospheric haze rings Pluto's silhouette like a luminous halo in this image taken by NASA's New Horizons spacecraft around midnight EDT on July 15. This global portrait of the atmosphere was captured when the spacecraft was about 1.25 million miles (2 million kilometers) from Pluto and shows structures as small as 12 miles across. The image was delivered to Earth on July 23.
