This movie shows a concatenation of images, hotly downloaded of the telescope today, April 22, 2013. While the frame rate is constant, the movie is time-lapse but by varying degrees. Credit: NAS...
Saturn Auroras From Hubble
Saturn appears serene and majestic in the first color composite made of images taken by NASA's Cassini spacecraft on its approach to the ringed planet, with arrival still 20 months away. The plane...
Are the moons tiny or are the rings vast? Both, in a way! The moons visible in this image, Pandora and Atlas, are quite small by astronomical standards, but the rings are also enormous.
The rings share this view with Mimas, a moon whose gravity influences the rings. To learn more about Mimas' gravitational influences, or resonances, see Perturbed Edge and Splendid Striations. Mim...
Resonance Moon and Rings
These images of dwarf planet Ceres, processed to enhance clarity, were taken on Feb. 19, 2015, from a distance of about 29,000 miles (46,000 kilometers), by NASA's Dawn spacecraft. Dawn observed Ce...

This is Cassini's best look yet at the Trojan moon Telesto (24 kilometers, or 15 miles across), which orbits Saturn about 60 degrees ahead of the much larger Tethys (1,071 kilometers, or 665 miles ...
At Launch Complex 40 on Cape Canaveral Air Station, the Mobile Service Tower has been retracted away from the Titan IVB/Centaur carrying the Cassini spacecraft and its attached Huygens probe.
Ready for Launch
Across the expanse of Saturn's rings, the Cassini spacecraft spies two small moons in consort. Atlas (32 kilometers, or 20 miles across) is seen exterior to the bright outer edge of the A ring. Da...
Ring Moon Rendezvous
This video describes Cassini measurements of high speed streams of tiny dust particles emanating from the vicinity of Saturn. It presents actual dust measurements and displays Cassini measurements ...
Cosmic Messengers From Saturn
The rings cannot hide the ragged, icy crescent of Rhea, here imaged in color by the Cassini spacecraft. The second-largest moon of Saturn shines brightly through gaps in the rings. Rhea (1,528 kil...
Wind-blown clouds and haze high in Saturn's atmosphere are captured in a movie made from images taken by the Cassini narrow angle camera between Feb. 15 and Feb. 19, 2004.

+ View Full Res This image was obtained by Cassini's radar instrument during a flyby on Feb. 22, 2007. The radar antenna was pointing toward Titan at an altitude of 1,000 kilometers (621 miles) ...
Titan Radar Swath (T-25 Flyby - Feb. 22, 2007)
This image, taken by NASA's Dawn spacecraft, shows the surface of dwarf planet Ceres from an altitude of 915 miles (1,470 kilometers). The image was taken on September 20, 2015, and has a resolutio...
Dawn HAMO Image 36
A shepherd moon can do more to define ring structures than just keep the flock of particles in line, as Cassini spacecraft images such as this have shown. Prometheus (102 kilometers, or 63 miles a...
The Hand of Prometheus
Tiny Daphnis appears as a bright dot in the Keeler Gap next to shadows cast by the moon and the edge waves it has created in the A ring in this image taken before Saturn's August 2009 equinox. Dap...

The Cassini spacecraft surveys the surface of Saturn's moon Enceladus in this image, which shows newly created terrain in the upper right meeting older, cratered terrain in the lower left. This vi...
Scanning Enceladus' Surface
These images compare surface features observed by NASA's Cassini spacecraft at the Xanadu region on Saturn's moon Titan (left), and features observed by NASA's Galileo spacecraft on Jupiter's crate...
Titan and Callisto
The Cassini spacecraft watches over the northern latitudes of Saturn's geologically active moon Enceladus while the planet's rings peek through in the distance in this snapshot. See Enceladus' Lea...
