Looking cool and serene, Saturn shares its soft glow with Cassini.
New insights into the nature of Saturn's rings are revealed in this panoramic mosaic of 15 images taken during the planet's August 2009 equinox.
These two Cassini images, taken four years before Saturn's August 2009 equinox, have taken on a new significance as data gathered at equinox indicate the streaks in these images are likely evidence of impacts into the planet's rings.
The bright streaks visible in these Cassini images taken during Saturn's August 2009 equinox are exciting evidence of a constant rain of interplanetary projectiles onto the planet's rings.
This mosaic of Cassini images, part of a larger mosaic of images captured just hours before exact equinox at Saturn, shows that the spiral corrugation in the planet's inner rings continues right up to the inner B ring ... an unexpected result that scientists are working to understand.
Several sets of shadows are cast onto the A ring in this image taken about a week after Saturn's August 2009 equinox.
Ring material, pulled to spectacular heights above the ring plane by the gravity of the moon Daphnis, casts long shadows on Saturn's A ring in this Cassini image taken about a month before the planet's August 2009 equinox.
Of the countless equinoxes Saturn has seen since the birth of the solar system, this one, captured here in a mosaic of light and dark, is the first witnessed up close by an emissary from Earth ... none other than our faithful robotic explorer, Cassini.
The Cassini spacecraft looks down on the north pole of Dione and the fine fractures that cross its trailing hemisphere.
A vertically extended structure or object in Saturn's F ring casts a shadow long enough to reach the A ring in this Cassini image taken just days before planet's August 2009 equinox.
The Cassini spacecraft captured this image of a small object in the outer portion of Saturn's B ring casting a shadow on the rings as Saturn approaches its August 2009 equinox.
Cassini spies a shadow cast by a vertically extended structure or object in the F ring in this image taken as Saturn approaches its August 2009 equinox.
As Saturn approaches its August 2009 equinox, a shadow is cast by a narrow, vertically extended feature in the F ring.
This mosaic of image swaths from Cassini's Titan Radar Mapper, taken with the synthetic-aperture radar (SAR), features a large dark region several hundred kilometers across that differs in several significant ways from potential lakes observed on Titan.
An enigmatic large basin appears in the south polar region of Saturn's moon Titan at the center of this Titan Radar Mapper image from NASA's Cassini spacecraft acquired on June 22, 2009.
These illustrations indicate possible ways in which the water vapor and ice particles in the plume of Enceladus may be formed.
This image shows the location of Cassini's most precise measurements so far of the surface temperatures at the active "tiger stripe" fractures that cut the south polar region of Enceladus.
At a Sun-Saturn-spacecraft, or phase, angle of 122 degrees, light is scattered from the dusty spokes toward Cassini's cameras.
These drawings depict explanations for the source of intense heat that has been measured coming from Enceladus' south polar region.
As the moon Enceladus eclipses its neighbor Mimas, Cassini records a scene possible only around the time of Saturn's approaching equinox.
