"Earth Beyond Rings" -- A view of Earth and the Moon as seen beyond Saturn's rings by Cassini.

"Near IR Saturn North Pole" -- A view of Saturn's north polar vortex processed using far red/near-infrared wavelengths captured by Cassini.

"Enceladus Plumes" -- A back-lit view of water-ice plumes at the south pole of Saturn's moon of Enceladus, and surface Saturnshine, as seen by Cassini.

"Europa Galileo" -- A view of Jupiter's moon Europa made using images taken by the Galileo orbiter.

"Hale Crater Scene HiRISE" -- A computer generated view within Mars' Hale Crater made using imagery and digital terrain model data captured by the HiRISE instrument aboard the Mars Reconnaissance Orbiter.

"Jupiter Great Red Spot" -- A composite view of Jupiter's Great Red Spot made using imagery captured by the Juno spacecraft on Perijove 7.

"Jupiter Marble Poster" -- A collage of Ultra-Wide-Angle Jupiter views created using reprojected images captured by the Juno spacecraft.

"Jupiter North Lats Fisheye" -- A ultra-wide-angle view of Jupiter centered on its mid-northern latitudes.

"Cassini Deorbit Site" -- A Cassini observation of its pending location of impact on Saturn as it completed its final orbit.

"MSL Self Portrait" -- A self portrait of the Curiosity Rover captured by the rover's arm-mounted camera.

"Near IR Saturn" -- A view of Saturn processed using far red/near-infrared wavelengths captured by Cassini.

"Boomerang Nebula Hubble" -- A Hubble image of the Boomerang Nebula. The Boomerang Nebula is about 5,000 light-years from Earth. Its temperature is around -460 degrees Fahrenheit.

"PIA21628_figA" -- Processed directly for NASA/JPL. The closest full color view of Saturn's rings taken by Cassini. Saturn's icy rings are thought to be pieces of comets, asteroids or shattered moons that broke up before they reached the planet.

"PIA21889_Enceladus_FigA_color" -- Processed directly for NASA/JPL. A full color view of Enceladus as it appears to set behind the limb of Saturn.

"Saturn Grand Finale Mosaic" -- The final full true color view of Saturn taken by Cassini as it approached impact.
