Pluto Paints Charon Red


full-res-charonThe New Horizons spacecraft took this high-resolution, enhanced color photo of Pluto’s largest moon Charon just before closest approach on 14 July, 2015. This image was created by combining blue, red and infrared images taken by the spacecraft’s Ralph/Multispectral Visual Imaging Camera. It’s been processed to highlight the variation of surface properties across Charon. The reddish material in the north (top) polar region (informally known as Mordor Macula) is methane that has escaped from Pluto’s atmosphere and been captured by Charon. Charon is 1,214 km across, and this image resolves details as small as 2.9 km.

The Dark Side of Pluto


PlutoNightNew Horizons was about 21,000 kilometers beyond Pluto, about 19 minutes after its closest approach, when it took this picture. The image also reveals Pluto’s tenuous and complex layers of hazy atmosphere. The crescent twilight landscape near the top of the frame are areas on the south of the planet including the nitrogen ice plains informally known as Sputnik Planum and rugged mountains of water-ice in the Norgay Montes.
