Reddish streaks cut across the surface of Tethys in this image. The streaks are narrow, curved lines on the moon’s surface, only a few miles wide but several hundred miles long. The yellowish tones on the left side of the view are a result of alteration of the moon’s surface by high-energy particles from Saturn’s magnetosphere. This particle radiation slams into the moon’s trailing hemisphere, modifying it chemically and changing its appearance in enhanced-color views like this one. The area of Tethys shown here is centered on 30 degrees north latitude, 187 degrees west longitude, and measures 305 by 258 miles (490 by 415 km) across. The original color images were obtained at a resolution of about 2,300 feet (700 m) per pixel on April 11, 2015. Image credit: NASA / JPL-Caltech / Space Science Institute.

Pluto nearly fills the frame in this image from NASA’s New Horizons spacecraft, taken on July 13, 2015, when the spacecraft was 476,000 miles (768,000 km) from the dwarf planet’s surface. This is the last and most detailed image sent to Earth before the spacecraft’s closest approach to Pluto on July 14. The color image has been combined with lower-resolution color information from the Ralph instrument that was acquired earlier on July 13. This view is dominated by the large, bright feature informally named the ‘heart,’ which measures around 1,000 miles (1,600 km) across. The heart’s diameter is about the same distance as from Denver to Chicago, in America’s heartland. The heart borders darker equatorial terrains, and the mottled terrain to its east (right) are complex. However, even at this resolution, much of the heart’s interior appears remarkably featureless-possibly a sign of ongoing geologic processes.
