This image was taken from a distance of 186 km from the center of Comet 67P/Churyumov-Gerasimenko; the jet is estimated to have a minimum speed of 10 m/s and originates from a location on the comet’s neck, in the rugged Anuket region.

The mysterious bright spots on Ceres lie in the Occator crater, which is about 60 miles (90 km) across and two miles (4 km) deep. This image comes from the animation, generated using data from NASA’s Dawn spacecraft; vertical relief has been exaggerated by a factor of five; exaggerating the relief helps scientists understand and visualize the topography much more easily, and highlights features that are sometimes subtle.

The asteroid 31 Euphrosyne glides across a field of background stars in this time-lapse view from NASA’s WISE spacecraft. WISE obtained the images used to create this view over a period of about a day around May 17, 2010, during which it observed the asteroid four times. The moving asteroid appears as a string of orange dots because it is much cooler than the distant background stars. Stars have temperatures in the thousands of degrees, but the asteroid is cooler than room temperature. Thus the stars are represented by shorter wavelength blue colors in this view, while the asteroid is shown in longer wavelength reddish colors. Image credit: NASA / JPL-Caltech.

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.
