Snapshots of a collision between two irregular rubble-pile asteroids, using a polyhedral element technique developed by Korycansky 
Cutaway view of convective upwellings inside the ice shell of Enceladus, an icy moon of Saturn, by James Roberts 
Martian slope streaks on an isolated hill. These features are forming at the present day; from work by Misha Kreslavsky 
View of an area near Lake Powell, with canyon systems resembling those found on Mars. From fieldwork by Reid Parsons and Charlie Barnhart 
Cluster of small craters on Mars, due to disruption of a single meteoroid on its way through the Martian atmosphere. From work by Misha Kreslavsky 
A snapshot from a 2D computer simulation of an explosive volcanic eruption. Reds and yellows represent supersonic flows, blues are subsonic. From work by Darcy Ogden and Gary Glatzmaier 
A snapshot from a 3D computer simulation of convection and magnetic field generation in the interior of Saturn. The zonal winds at the surface are displayed (reds are eastward, blues westward) and compared to the observed winds on Saturn. From work by Gary Glatzmaier. 
Cutaway diagram of Saturn's moon Enceladus. Rising hot material in its interior may have caused this body to roll over on its side. From work by Francis Nimmo. 
Comparison between observed (left) and modelled (right) valley networks on Mars, suggesting that these river-like features were formed during an arid period of the planet's history. From work by Charlie Barnhart. 
Snapshot of a large impact on Mars, which may have been responsible for half of Mars being lower and smoother than the other half. From work by Francis Nimmo. 
False-colour infra-red image of Mawrth Vallis, Mars. In this image, each colour represents a different mineralogy. From work by Nancy McKeown. 
Snapshot of a planetary collision in which the impacting body gets ripped apart into a series of smaller, iron-rich fragments (red). This scenario may help to explain the origin of metallic asteroids. From work by Erik Asphaug
