Cyclones swirl around the south pole, and white oval storms can be seen near the limb -- the apparent edge of the planet -- in this image of Jupiter’s south polar region taken by the JunoCam imager aboard NASA’s Juno spacecraft. The image was acquired on February 2, 2017, from an altitude of 47,600 miles (76,600 km) above Jupiter’s swirling cloud deck. Prior to the Feb. 2 flyby, the public was invited to vote for their favorite points of interest in the Jovian atmosphere for JunoCam to image. The point of interest captured here was titled ‘Jovian Antarctica’ by a member of the public, in reference to Earth’s Antarctica. Image credit: NASA / JPL-Caltech / SwRI / MSSS.

Ahuna Mons, Ceres’ lonely mountain, is seen in this simulated perspective view. The elevation has been exaggerated by a factor of two. The view was made using enhanced-color images from NASA’s Dawn orbiter. Images taken using blue (440 nm), green (750 nm) and infrared (960 nm) spectral filters were combined to create the view. The spacecraft’s framing camera took the images from Dawn’s low-altitude mapping orbit, from an altitude of 240 miles (385 km) in August 2016.

This Cassini image features a density wave in Saturn’s A ring (at left) that lies around 83,575 miles (134,500 km) from Saturn. Density waves are accumulations of particles at certain distances from the planet. This feature is filled with clumpy perturbations, which researchers informally refer to as ‘straw.’ The wave itself is created by the gravity of Saturn’s moons Janus and Epimetheus, which share the same orbit around the gas giant. Elsewhere, the scene is dominated by ‘wakes’ from a recent pass of the ring moon Pan. The image was taken in visible light with Cassini’s wide-angle camera on December 18, 2016. The view was obtained at a distance of approximately 34,000 miles (56,000 km) from the rings and looks toward the unilluminated side of the rings.

This view of a Martian rock slab called ‘Old Soaker,’ which has a network of cracks that may have originated in drying mud, comes from the Mast Camera on NASA’s Curiosity Mars rover. The location is within an exposure of Murray formation mudstone on lower Mount Sharp inside Gale Crater. Mud cracks would be evidence of a time more than 3 billion years ago when dry intervals interrupted wetter periods that supported lakes in the area. Several images from Mast Camera’s left-eye camera are combined into this mosaic view. They were taken on Dec. 20, 2016, during the 1,555th sol of Curiosity’s work on Mars. The Old Soaker slab is about 4 feet (1.2 m) long. Image credit: NASA / JPL-Caltech / MSSS.

Color composite of Phobos taken with TGO’s CaSSIS camera on November 26, 2016. The observation was made at a distance of 4,785 miles (7,700 km). To create the final color image, two images were taken through each of the four color filters of the camera -- panchromatic, blue-green, red and infrared -- and then stitched together and combined to produce the high-resolution composite. Two of the color filters used by CaSSIS lie outside the wavelength response of the human eye, so this is not a ‘true’ color image. However, showing the data as a color representation can reveal details of the surface mineralogy. Different colors are clearly seen, with the bluest part in the direction of the large crater Stickney, which is out of view over the limb to the left. Although the exact composition of the material is unknown, the color differences are thought to be caused by compositional variations on scales of hundreds of feet to several miles.
