Two sizes of ripples are evident in this December 13, 2015, view of a top of a Martian sand dune, from Curiosity. Sand dunes and the smaller type of ripples also exist on Earth. The larger ripples -- roughly 10 feet (3 m) apart -- are a type not seen on our planet nor previously recognized as a distinct type on Mars. Scale bar - 2 m (79 inches).

This X-ray image shows extended emission around the magnetar Swift J1834.9-0846. The glow arises from a cloud of fast-moving particles produced by the neutron star and corralled around it. Color indicates X-ray energies, with 2,000-3,000 electron volts (eV) in red, 3,000-4,500 eV in green, and 5,000 to 10,000 eV in blue. The image combines observations by XMM-Newton taken on March 16 and October 16, 2014. Image credit: ESA / XMM-Newton / G. Younes et al.

This Pluto mosaic was made from New Horizons LORRI images taken on July 14, 2015, from a distance of 49,700 miles (80,000 km). This view is projected from a point 1,118 miles (1,800 km) above Pluto’s equator, looking northeast over the dark, cratered Cthulhu Regio toward the bright, smooth expanse of icy plains called Sputnik Planum. Pluto’s North Pole is off the image to the left. This mosaic was produced with panchromatic images from the New Horizons LORRI camera, with color overlaid from the Ralph color mapper onboard New Horizons. Image credit: S.A.
