Saturns icy rings shine in scattered sunlight in this view, which looks toward the unilluminated northern side of the rings from about 15 degrees above the ringplane.

The Sun currently illuminates the rings from the south. Some of the sunlight not reflected from the rings southern face is scattered through the countless particles, setting the rings aglow.

The inner F-ring shepherd moon Prometheus (86 kilometers, or 53 miles across at its widest point) appears at lower left.

Images taken using red, green and blue spectral filters were combined to create this natural color view. Bright clumps of material in the narrow F ring moved in their orbits between each of the color exposures, creating a chromatic misalignment in several places that provides some sense of the continuous motion within the ring system.

The images were obtained with the Cassini spacecraft wide-angle camera on July 4, 2008 at a distance of approximately 1.2 million kilometers (770,000 miles) from Saturn. The Sun-ring-spacecraft, or phase, angle was 28 degrees. Image scale is 70 kilometers (44 miles) per pixel.

Saturns northern hemisphere reached its summer solstice in mid-2017, bringing continuous sunshine to the planets far north.

The solstice took place on May 24, 2017. The Cassini mission is using the unparalleled opportunity to observe changes that occur on the planet as the Saturnian seasons turn.

This view looks toward the sunlit side of the rings from about 17 degrees above the ring plane. The image was taken with the Cassini spacecraft wide-angle camera on April 17, 2017 using a spectral filter which preferentially admits wavelengths of near-infrared light centered at 939 nanometers.

The view was acquired at a distance of approximately 733,000 miles (1.2 million kilometers) from Saturn. Image scale is 44 miles (70 kilometers) per pixel.

These two views of Saturns moon Titan exemplify how NASAs Cassini spacecraft has revealed the surface of this fascinating world.

Cassini carried several instruments to pierce the veil of hydrocarbon haze that enshrouds Titan. These include the spacecrafts radar and visual and infrared mapping spectrometer, or VIMS. The missions imaging cameras also have several spectral filters sensitive to specific wavelengths of infrared light that are able to make it through the haze to the surface and back into space. These "spectral windows" have enable the imaging cameras to map nearly the entire surface of Titan.

In addition to Titans surface, images from both the imaging cameras and VIMS have provided windows into the moons ever-changing atmosphere, chronicling the appearance and movement of hazes and clouds over the years. A large, bright and feathery band of summer clouds can be seen arcing across high northern latitudes in the view at right.

These views were obtained with the Cassini spacecraft narrow-angle camera on March 21, 2017. Images taken using red, green and blue spectral filters were combined to create the natural-color view at left. The false-color view at right was made by substituting an infrared image (centered at 938 nanometers) for the red color channel.

The views were acquired at a distance of approximately 613,000 miles (986,000 kilometers) from Titan. Image scale is about 4 miles (6 kilometers) per pixel.

This false-color view from NASAs Cassini spacecraft gazes toward the rings beyond Saturns sunlit horizon. Along the limb (the planets edge) at left can be seen a thin, detached haze. This haze vanishes toward the right side of the scene.

Cassini will pass through Saturns upper atmosphere during the final five orbits of the mission, before making a fateful plunge into Saturn on Sept. 15, 2017. The region through which the spacecraft will fly on those last orbits is well above the haze seen here, which is in Saturns stratosphere. In fact, even when Cassini plunges toward Saturn to meet its fate, contact with the spacecraft is expected to be lost before it reaches the depth of this haze.

This view is a false-color composite made using images taken in red, green and ultraviolet spectral filters. The images were obtained using the Cassini spacecraft narrow-angle camera on July 16, 2017, at a distance of about 777,000 miles (1.25 million kilometers) from Saturn. Image scale is about 4 miles (7 kilometers) per pixel on Saturn.

NASAs Cassini spacecraft captured this view as it neared icy Enceladus for its closest-ever dive past the moons active south polar region. The view shows heavily cratered northern latitudes at top, transitioning to fractured, wrinkled terrain in the middle and southern latitudes. The wavy boundary of the moons active south polar region -- Cassinis destination for this flyby -- is visible at bottom, where it disappears into wintry darkness.

This view looks towards the Saturn-facing side of Enceladus. North on Enceladus is up and rotated 23 degrees to the right. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on October 28, 2015.

The view was acquired at a distance of approximately 60,000 miles (96,000 kilometers) from Enceladus and at a Sun-Enceladus-spacecraft, or phase, angle of 45 degrees. Image scale is 1,896 feet (578 meters) per pixel.
