Titan’s south polar vortex stands out against the orange and blue haze layers that are characteristic of the hazy moon’s atmosphere. This view looks towards the trailing hemisphere of Titan (3,200 miles, or 5,150 km across). North on Titan is up and rotated 17 degrees to the left. Images taken using red, green and blue spectral filters were combined to create this natural-color view. The image was taken with the Cassini spacecraft narrow-angle camera on July 30, 2013. The view was acquired at a distance of approximately 895,000 miles (1.441 million km) from Titan. Image credit: NASA / JPL-Caltech / Space Science Institute.

This image from NASA’s Cassini spacecraft shows Saturn and its rings. Six of Saturn’s moons make a faint appearance in this image: the ice-covered moon Enceladus can be seen at the 1 o’clock position; directly below Enceladus, just outside the F ring (the thin, farthest ring from the planet seen in this image) lies the small moon Epimetheus; following the F ring clock-wise from Epimetheus, the next moon seen is Janus; at about the 4:30 position and outward from the F ring is Mimas; inward of Mimas and still at about the 4:30 position is the F-ring-disrupting moon, Pandora; moving around to the 10 o’clock position, just inside of the F ring, is the moon Prometheus.

This false-color image demonstrates how use of special filters available on Curiosity’s Mastcam camera can reveal the presence of certain minerals in target rocks. It is a composite of images taken through three ‘science’ filters chosen for making hematite stand out as exaggerated purple. Mastcam’s narrow-band filters used for this view help to increase spectral contrast, making blues bluer and reds redder, particularly with the processing used to boost contrast in each of the component images of this composite. Fine-grained hematite preferentially absorbs sunlight around in the green portion of the spectrum around 527 nm. That gives it the purple look from a combination of red and blue light reflected by the hematite and reaching the camera through the other two filters. Bright lines within the rocks are fractures filled with calcium sulfate minerals. Image credit: NASA / JPL-Caltech / MSSS.

This graphic illustrates how water might be heated inside Enceladus. Over time, cool ocean water seeps into the moon’s porous core. Pockets of water reaching deep into the interior are warmed by contact with rock in the tidally heated interior and subsequently rise owing to the positive buoyancy, leading to further interaction with the rocks. The heat deposited at the boundary between the seafloor and ocean powers hydrothermal vents. Heat and rocky particles are transported through the ocean, triggering localized melting in the icy shell above. This leads to the formation of fissures, from which jets of water vapor and the rocky particles from the seafloor are ejected into space. In the graphic, the interior ‘slice’ is an excerpt from a new model that simulated this process. The orange glow represents the parts of the core where temperatures reach at least 194 degrees Fahrenheit. Tidal heating owing to the friction arising between particles in the porous core provides a key source of energy, but is not illustrated in this graphic. The tidal heating results primarily from the gravitational pull from Saturn.
