OSIRIS instrument on the Rosetta spacecraft captured this image of Comet 67P/Churyumov–Gerasimenko on November 12, 2014; marked is what Rosetta scientists believe to be the Philae lander above the rim of the large depression – named Hatmehit – on the comet’s small lobe.

This image shows conditions observed by Cassini during a flyby on December 1, 2013, when the magnetosphere of Saturn was highly compressed, exposing Titan to the full force of the solar wind. In analyzing data from the encounter, the researchers observed that the moon interacted with the solar wind much like the planets Mars and Venus, or a comet. Specifically, they saw that the solar wind draped itself around Titan, creating a shockwave that formed around Titan where the full-force solar wind rammed into the atmosphere of the moon. Previously, scientists had thought Titan would have a different sort of interaction with the solar wind because of the complex atmospheric chemistry of the moon. Image credit: NASA / JPL-Caltech.

The Nili Fossae system, part of which is shown in this image, is an area of great geological interest near the giant Isidis impact basin, northeast of the Syrtis Major volcanic province. The system contains numerous troughs, one of which can be seen crossing the lower left of this image. On the plateau above, several depressions can be seen, some of them extending into the trough. A large, 55 km-diameter impact crater with a central pit can be seen on the right. This image was acquired by the High Resolution Stereo Camera on the Mars Express on 16 October 2014. North is to the right, east is up. Image credit: ESA / DLR / FU Berlin / CC BY-SA 3.0 IGO.
