Pluto at high phase, showing its brilliant backlit hazy atmosphere. Above: The original image after processing to enhance detail.
Below: The same image, “unwrapped” such that Pluto’s horizon has been stretched into a straight line. Radial features in the original
image appear vertical here; several of the many prominent bright radial rays are marked, candidate sunbeams cast by Pluto’s topography
in the twilight sun. Red and cyan plus symbols mark same location in both versions of the image. Many other features are visible,
including concentric haze layers in the atmosphere which appear as stacked horizontal bands.
