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.

This colorful view of Mercury was produced by using images from the color base map imaging campaign during MESSENGER’s primary mission. These colors are not what Mercury would look like to the human eye, but rather the colors enhance the chemical, mineralogical, and physical differences between the rocks that make up the planet’s surface.

This image from NASA’s Galileo spacecraft shows Io. There are rugged mountains several miles high, layered materials forming plateaus, and many irregular depressions called volcanic calderas. Several of the dark, flow-like features correspond to hot spots, and may be active lava flows. There are no landforms resembling impact craters, as the volcanism covers the surface with new deposits much more rapidly than the flux of comets and asteroids can create large impact craters. The picture is centered on the side of Io that always faces away from Jupiter; north is to the top. Image credit: NASA / JPL / University of Arizona.

This view of Pluto, based on the latest images to be downlinked from NASA’s New Horizons spacecraft, shows what you would see if you were approximately 1,100 miles (1,800 km) above Pluto’s equatorial area, looking northeast over the dark, cratered, named Cthulhu Regio toward the bright, smooth, expanse of icy plains called Sputnik Planum. The entire expanse of terrain seen in this image is 1,100 miles (1,800 km) across. Image credit: NASA / Johns Hopkins University Applied Physics Laboratory / Southwest Research Institute.

This artist’s concept of a young solar system shows gas giants forming first, while the gas nebula is present. Prof Martin Duncan and co-authors used computer simulations to nail down how Jupiter and Saturn evolved in our own Solar System. These calculations show that the cores of gas giants likely formed by gradually accumulating a population of ‘planetary pebbles’ - icy objects about a foot in diameter.

This image from NASA’s Cassini spacecraft shows a part of Dione’s surface that is covered by linear, curving features, called chasmata. The Voyager spacecrafts observed Dione in 1980 showing a complex surface structure, with wispy features on its trailing hemisphere. The nature of these features was unclear until 2004, when the Cassini spacecraft showed that they weren’t surface deposits of frost, as some had suspected, but rather a pattern of bright icy cliffs among myriad fractures. One possibility is that this stress pattern may be related to Dione’s orbital evolution and the effect of tidal stresses over time. This view looks toward the trailing hemisphere of Dione. Cassini obtained the image with its narrow-angle camera on April 11, 2015. The view was acquired at a distance of 68,000 miles (110,000 km) from Dione. North on Dione is up.
