The scene features Titan, largest, and Dione, third largest moon of Saturn. Pale Dione is about 1,100 kilometers across and orbits over 300,000 kilometers from the visible outer edge of the A ring. At 5,150 kilometers across, Titan is about 2.3 million kilometers from Cassini, while Dione is 3.2 million kilometers away.

Amazing Images: The Best Science Photos of the Week

NASA's Cassini spacecraft has capped 2013 with a spectacular new collection of Saturn photos showcasing the planet's beauty, as well with its trademark rings and strange moons. The newly released Saturn photos by Cassini include two views of Enceladus, Saturn's sixth-largest moon. Enceladus is a winter-appropriate ice world. Geysers at its poles shoot ice particles into space, some of which make it into orbit around Saturn. Some of this space "snow" becomes part of Saturn's E ring, Saturn's…

May 2010 Moons & Rings Before Saturn Credit: Cassini Imaging Team, ISS, JPL, ESA, NASA Another striking alignment occurred last March in the view of humanity's Saturn-orbiting Cassini spacecraft. Rhea, one of Saturn's larger moons, was caught passing Epimetheus, one of Saturn's smaller moons. Epimetheus is actually well behind the heavily cratered Rhea. Further back, several of the complex rings of Saturn can b seen crossing the image horizontally. Behind both the moons & rings is giant…

Pandora (50 miles, or 81 kilometers across) orbits outside the F ring, while another shepherd moon Prometheus (53 miles, or 86 kilometers across), orbits inside, both helping to prevent the ring from spreading. Cassini spacecraft took the image in visible light with the wide-angle camera on March 8, 2014. Image released Aug. 11, 2014. %u2014 Tom Chao
