This image of an impact crater in the Sirenum Fossae region of Mars was taken by NASA’s Mars Reconnaissance Orbiter on March 30, 2015. The crater is approximately 3,300 feet (1-km) wide and appears relatively recent as it has a sharp rim and well-preserved ejecta. The steep inner slopes are carved by gullies and include possible recurring slope lineae on the equator-facing slopes. Image credit: NASA / JPL / University of Arizona / Alfred McEwen.

A close-up of the canyons on Charon, taken by New Horizons’ LORRI instrument during the spacecraft’s close approach to the Pluto system on July 14, 2015. When New Horizons took this image, a distance of 48,900 miles (78,700 km) separated the spacecraft and Charon. The image measures 240 miles (386 km) long and 110 miles (175 km) wide. Multiple views taken by the spacecraft as it passed by the Pluto’s largest moon allow stereo measurements of topography, shown in the color-coded version of the image. The scale bar indicates relative elevation. Image credit: NASA / Johns Hopkins University Applied Physics Laboratory / Southwest Research Institute.

This illustration is a speculative representation of the interior of Enceladus with a global ocean between its rocky core and icy crust. The thickness of layers shown here is not to scale. Scientists determined that the slight wobble of the moon as it orbits Saturn is much too large for the moon to be frozen from surface to core. The wobble, technically referred to as a libration, reveals that the crust of Enceladus is disconnected from its rocky interior. Image credit: NASA / JPL-Caltech.
