Caption:

This image of Charon was taken by New Horizons' Long Range Reconnaissance Imager (LORRI) at 4:23 UT on July 9, 2015, from a range of 3.9 million miles (6.3 million kilometers). It reveals fascinating detail, never before seen, on the surface of Pluto's giant moon, which has a diameter of 750 miles (1208 kilometers). The dark north polar region, which has been seen for several weeks on approach, is still prominent, but numerous bright spots, scattered over Charon's surface, are now also visible. It is possible that many of these spots are bright icy material excavated from Charon's subsurface by impact craters, but whether this is true will become clearer in the next few days.

Three consecutive images were combined and sharpened, using a process called deconvolution, to create this view. Deconvolution enhances real detail but can also generate spurious features, including the bright margin seen on the upper edge of the disk.

The wireframe globe shows the orientation of Charon in the image -- thicker lines indicate the equator and the prime meridian (the direction facing Pluto). Central longitude on Charon is 266°.
