The fresh pictures are portions of images that NASA’s New Horizons spacecraft snapped during its closest-ever flyby of Pluto on July 14. Thanks to a resolution of about 250-280 feet (77-85 meters) per pixel, features smaller than half a city block on Pluto’s surface are perfectly visible. NASA just slightly enhanced the pictures with color data of a lower resolution – about 2,066 feet, or 630 meters, per pixel.
