25 NOVEMBER-DECEMBER 2017 SATURN Haze on the horizon This false-color view from NASA's Cassini spacecraft gazes toward the rings beyond Saturn's sunlit horizon. Along the limb (the planet's edge) at left can be seen a thin, detached haze. The haze vanishes toward the right side of the scene. This view is a false- color composite made using images taken in red, green and ultra- violet spectral filters. The images were obtained using the Cassini spacecraft narrow-angle camera on July 16, 2017, at a distance of about 1.25 million kilometers from Saturn. Image scale is about 7 kilometers per pixel on Saturn. [NASA/JPL/Space Science Institute]
