Day and night side narrow angle images taken on January 1, 2001 illustrating storms visible on the day side which are the sources of visible lightning when viewed on the night side. The images have been enhanced in contrast. Note the two day-side occurrences of high clouds, in the upper and lower parts of the image, are coincident with lightning storms seen on the darkside. The storms occur at 34.5 degrees and 23.5 degrees North latitude, within one degree of the latitudes at which similar...

This image of the floor of Kepler crater in early morning twilight highlights the quality of images from the High Resolution Imaging Science Experiment (HiRISE) camera even under extremely minimal lighting conditions. At the time that this image was acquired, the sun had just barely risen over the horizon. This faint illumination reveals a terrain dotted by numerous exhumed impact craters. These impact craters once dominated the landscape of this region until they were buried under a blanket of...

This composite image shows a massive mountain range running just south of Titan's equator. Near the center of the image, the mountain range runs from southeast to northwest. It is about 150 kilometers long (93 miles) and 30 kilometers (19 miles) wide and about 1.5 kilometers (nearly a mile) high. This range, and smaller ranges to the west and east of the main range, probably results from material welling up below as the crust of Titan is pulled apart by tectonic forces. This image was obtained...

This color image of Jupiter was taken by the camera onboard NASA's Cassini spacecraft when it was 81.3 million kilometers (50.5 million miles) from the planet. It is composed of images taken in the blue, green, and red regions of the spectrum and is therefore close to the true color of Jupiter that one would see through an Earth-based telescope. The image is remarkably similar to images taken by NASA's Voyager 1 and 2 spacecraft more than 21 years ago, illustrating the stability of Jupiter's...

During a non-targeted flyby by the Cassini spacecraft of Saturn's moon Enceladus on Nov. 26, 2005, Cassini's visual and infrared mapping spectrometer measured the spectrum of the plumes originating from the south pole of the icy moon. The instrument captured a very clear signature of small ice particles in the plume data, at the 2.9 micron wavelength. This image of Enceladus, taken with the visual and infrared mapping spectrometer, shows not only the plume over the south pole, but also the dark...

This composite image, composed of two images taken with Cassini's visual and infrared mapping spectrometer, shows a crescent view of Saturn's moon Titan. The data were obtained during a flyby on July 22, 2006, at a distance of 15,700 kilometers (9,700 miles) from Titan. The image was constructed from images taken at wavelengths of 1.26 microns shown in blue, 2 microns shown in green, and 5 microns shown in red. The Cassini-Huygens mission is a cooperative project of NASA, the European Space...

This global infrared map of Titan was composed with data from Cassini's visual and infrared mapping spectrometer taken during the last two Titan flybys, on Dec. 26, 2005, and Jan. 15, 2006. The map was constructed from false-color images taken at wavelengths of 1.6 microns shown in blue, 2.01 microns in green, and 5 microns in red. All three images are of reflected sunlight. The viewing geometry of the December flyby is roughly on the opposite hemisphere of the flyby in January. There are...

This image is one of seven from the narrow-angle camera on NASA's Cassini spacecraft assembled as a brief movie of high-altitude cloud movements on Jupiter. It was taken in early October 2000. The images were taken at a wavelength that is absorbed by methane, one chemical in Jupiter's lower clouds. So, dark areas are relatively free of high clouds, and the camera sees through to the methane in a lower level. Bright areas are places with high, thick clouds that shield the methane below. The area...

One moment in an ancient, orbital dance is caught in this color picture taken by NASA's Cassini spacecraft on Dec. 7, 2000, just as two of Jupiter's four major moons, Europa and Callisto, were nearly perfectly aligned with each other and the center of the planet. The distances are deceiving. Europa, seen against Jupiter, is 600,000 kilometers (370,000 miles) above the planet's cloud tops. Callisto, at lower left, is nearly three times that distance from the cloud tops. Europa is a bit smaller...

A high-altitude haze layer residing some 400 kilometers (249 miles) above the surface of Titan is seen here traced along the limb of Titan as silhouetted against the glow of Titan's atmosphere produced by the fluorescence of methane gas. This detached haze layer can be seen as a dark lane imbedded within the gold-colored fluorescent layers of Titan. This image of Titan's limb and surface was obtained by the Cassini spacecraft's visual infrared mapping spectrometer on Dec. 13, 2004 from a...

This false-color image of Saturn was constructed by combining three images at three different infrared wavelengths. The image at the upper left was taken at 1.3 microns, where both Saturn and its rings strongly reflect light. The center image in the top panel was taken at 2.4 microns, where the rings strongly reflect light, but Saturn, because of the methane in its atmosphere, absorbs most of the light. The third image on the right in the panel was taken at a wavelength of 5 microns where,...

This image depicts Saturn's moon Titan as seen by the visual and infrared mapping spectrometer after closest approach on a July 22, 2006, flyby. The image was generated using the 5 micron wavelength for red, the 2 micron wavelength for green and the 1.2 micron wavelength for blue. The clouds, circled in the annotated version, are of the type seen previously and reported in the journal Science. The image shows the clouds spreading out along the 40-degree-south latitude line. This image was taken...

It shows that the color as well as texture or morphology varies from layer to layer. Some of the color variations may be caused by small amounts of water frost on the surface, or they may be due to...

Europa, a moon of Jupiter, appears as a thick crescent in this enhanced-color image from NASA's Galileo spacecraft, which has been orbiting Jupiter since 1995. The view combines images taken in violet, green and near-infrared filters in 1998 and 1995. The colors have been stretched to show the subtle differences in materials that cover the icy surface of Europa. Reddish linear features are some of the cracks and ridges, thousands of kilometers long, which are caused by the tides raised by the...

This gamma ray spectrometer map of the mid-latitude region of Mars is based on gamma-rays from the element thorium. Thorium is a naturally radioactive element that exists in rocks and soils in extremely small amounts. The region of highest thorium content, shown in red, is found in the northern part of Acidalia Planitia (50 degrees latitude, -30 degrees longitude). Areas of low thorium content, shown in blue, are spread widely across the planet with significant low abundances located to the...

This image taken by Cassini's visual and infrared mapping spectrometer clearly shows surface features on Titan. It is a composite of false-color images taken at three infrared wavelengths: 2 microns (blue); 2.7 microns (red); and 5 microns (green). A methane cloud can be seen at the south pole (bottom of image). This picture was obtained as Cassini flew by Titan at altitudes ranging from 100,000 to 140,000 kilometers (88,000 to 63,000 miles), less than two hours before the spacecraft's closest...

This observation (<a href="http://hirise.lpl.arizona.edu/PSP_001674_1610" class="external free" target="wpext">PSP_001674_1610</a>) covers a small part of the plains surrounding the volcano Tyrrhena Patera. Most of this area is covered by a thick layer of "mantling" material which hides the underlying rocks. Infrared data from the Mars Odyssey spacecraft suggested that this area is rockier than most of the region. The HiRISE...
