. These image shows the difference between two sets of 48 combined 10-second exposures with New Horizons' Long Range Reconnaissance Imager (LORRI) camera, taken at 8:40 UTC and 10:25 UTC on June 26, 2015, from a range of 13.4 million miles (21.5 million kilometers) to Pluto. The known small moons, Nix, Hydra, Kerberos and Styx, are visible as adjacent bright and dark pairs of dots due to their motion in the 105 minutes between the two image sets. NASA/JHUAPL/SwRI
