UPI Pictures of the Year 2015 -- NEWS & FEATURES

Pluto gets into the holiday spirit, decked out in red and green, in an image produced by the New Horizons composition team and released by NASA on December 24, 2015. The team used a pair of Ralph/LEISA instrument scans obtained from a mean range of 67,000 miles (108,000 kilometers) on July 14, 2015. The resolution is about 7 kilometers per LEISA pixel. Three infrared wavelength ranges (2.28-2.23, 1.25-1.30 and 1.64-1.73 microns) were placed into the three color channels (red, green and blue, respectively) to create this false color Christmas holiday portrait.
