Fire and Ice

Saturn's largest and second largest moons, Titan and Rhea, appear to be stacked on top of each other in this true-color scene from NASA's Cassini spacecraft. The north polar hood can be seen on Titan (3,200 miles or 5,150 kilometers across) appearing as a detached layer at the top of the moon on the top right....

Ring Backdrop

Saturn moon Enceladus brightly reflects sunlight before a backdrop of the planet rings and the rings shadows cast onto the planet. NASA Cassini spacecraft captured this snapshot during its flyby of the moon on Nov. 30, 2010.

Titan Subsurface Reservoirs Artist Concept

Scientists modeled how methane rainfall runoff would interact with the porous, icy crust of Saturn moon Titan and found that a subsurface methane aquifer might have its composition changed over time due to the formation of materials called clathrates.

Preventing Data "Washout"

If Cassini had taken an exposure long enough to make those faint outer plumes visible to a standard camera, the brightly lit crescent of Enceladus itself would have turned into a giant, blown-out blinding white smear, destroying all the data near the surface. False-color processing allows scientists to look at the brightest areas and the dimmest areas at the exact same time without losing details to glare or shadow
