Kevin M. Gill, a software engineer and data wrangler at NASA-JPL, created the fantastic video below "using still images taken by the Cassini spacecraft during it's flyby of Jupiter and while at Saturn.
"Shown is Io and Europa over Jupiter's Great Red Spot and then Titan as it passes over Saturn and it's edge-on rings," Gill wrote on Flickr.

Earth shares a cool phenomenon with Jupiter, Uranus, Neptune, and Saturn: all have observable auroras. NASA created a lovely animation of Saturn's, as well as some cool still images. Read the rest
The Cassini spacecraft is on final approach to Saturn, following confirmation by mission navigators that it is on course to dive into the planet’s atmosphere on Friday, Sept. 15. Read the rest
Astroparticle physicist Sophia Nasr posted a gorgeous photo of Saturn's north pole, processed to account for a luminance layer. Instead of a reddish hue, it is a breathtaking cerulean blue. Jason Major replicated the results. Read the rest
NASA's JPL is counting down the days to the scheduled end of Cassini's mission in September. Erik Wernquist created this awe-inspiring overview of Cassini's final months of existence. Read the rest
A breathtaking photo of Saturn's moon Mimas taken this week by NASA's Cassini space probe.
You may recall, that another photo (below) of Mimas raised concerns that it isn't actually a moon but rather the Death Star.

Having settled into orbit around Saturn, the Cassini probe has begun returning new images of the gas giant. The BBC reports that it will be "making a series of daredevil maneuvers" in the coming months, risking doom near Saturn's moons to get better shots of them and the rings.
Cassini began what are known as its ring-grazing orbits on 30 November. Each of these week-long orbits - 20 in all - lifts the spacecraft high above Saturn's northern hemisphere before sending it hurtling past the outer edges of the planet's main rings.
Nasa said that it would release images from future passes that included some of the closest-ever views of the outer rings and small moons that orbit there.

NASA just released this beautiful composite infrared view of Saturn's moon Titan. The Cassini spacecraft captured the image last month during its flyby about 6,200 miles above the moon's surface. From NASA:

The view looks toward terrain that is mostly on the Saturn-facing hemisphere of Titan. The scene features the parallel, dark, dune-filled regions named Fensal (to the north) and Aztlan (to the south), which form the shape of a sideways letter "H."
Several places on the image show the surface at higher resolution than elsewhere. These areas, called subframes, show more detail because they were acquired near closest approach. They have finer resolution, but cover smaller areas than data obtained when Cassini was farther away from Titan.
Two of the new images show the surface of Dione at the best resolution ever.
Researchers created this enhanced-color image by compositing recent shots of Tethys taken by Cassini. Current top hypotheses for the unusual red arcs are: Read the rest
Fun fact: Saturn has a storm that's every bit as big as Jupiter's better-known Great Red Spot. It's been spinning over Saturn's north pole for 30 years. And it's shaped like a hexagon. Read the rest

Cassini's very last targeted flyby of Saturn's moon, Rhea, occurred this past weekend, and images from that event are now on the ground and available for your discerning examination.
Take a good, long, luxurious look at these sights from another world, as they will be the last close-ups you'll ever see of this particular moon.

Every so often, our cameras on Cassini digitally record, either intentionally or incidentally, other celestial bodies besides those found around Saturn. The Cassini Imaging Team is releasing a pair of images that did just that. Venus, a lovely shining beacon of light and Earth's `twin' planet, was recently sighted amidst the glories of Saturn and its rings.
Carolyn Porco, Cassini Imaging Team Leader and director of CICLOPS in Boulder, CO, writes:
For no other reason than that they are gorgeous, the Cassini imaging team is releasing today a set of fabulous images of Saturn and Titan...in living color...for your day-dreaming enjoyment. Note that our presence at Saturn for the last 8 years has made possible the sighting of subtle changes with time, and one such change is obvious here. As the seasons have advanced, and spring has come to the north and autumn to the south throughout the Saturn system, the azure blue in the northern winter Saturnian hemisphere that greeted Cassini upon its arrival in 2004 is now fading; and it is now the southern hemisphere, in its approach to winter, that is taking on a bluish hue.
[B]ack here on Earth, the Cassini mission was recently given rave reviews by a panel of planetary scientists and NASA program managers for its contributions to our understanding of the solar system, a circumstance that bodes well for a well-funded continuing mission over the next 5 years. Despite the fact that we can't know exactly what the next five years will bring us, we can be certain that whatever it is will be wondrous.
