NavCam view of comet Churyumov-Gerasimenko on September 19, 2014

NavCam view of comet Churyumov-Gerasimenko on September 19, 2014
NavCam view of comet Churyumov-Gerasimenko on September 19, 2014 Rosetta captured a 4-image mosaic of the comet from a distance of 28.6 kilometers on September 19. Faint jets emanate from the comet's neck. In this view the comet measures 4.8 kilometers wide, end to end. This is a higher-phase view than many earlier ones, so there are longer shadows. Boulders near the terminator (day-night boundary) appear bright because their steep sides face the Sun more squarely than the ground upon which they sit. ESA / Rosetta / NavCam / Emily Lakdawalla

The component images for this mosaic were flat-fielded before being combined using Microsoft ICE. Lots of jets are visible in this image if you adjust its brightness:
