These photos of the four Galilean satellites of Jupiter were taken by Voyager 1 during its approach to the planet in early March 1979. Io (top left), Europa (top right), Ganymede (bottom left) and Callisto (bottom right) are shown in their correct relative sizes: Ganymede and Callisto are both larger than the planet Mercury; Io and Europa are about the same size as the Moon. Image processing also preserves the relative contrasts of the satellites. Thus it is apparent that Europa has the least...

An 8-kilometer (5-mile) wide crater of possible impact origin is shown in this stereoscopic view of an isolated part of the Bolivian Amazon. The view is derived from an Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) satellite image and a Shuttle Radar Topography Mission (SRTM) elevation model. The circular feature covering much of the image, known as the Iturralde Structure, is possibly the Earth's most recent "big" impact event recording collision with a...

14 February 2004 Happy St. Valentine's Day from the Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) team! This collection of images acquired over the past 3 Mars years shows some of the heart-shaped features found on Mars by the MGS MOC. * The heart in E04-01788 is a low mesa located near 46.7N, 29.0W, and is about 636 m (2,086 ft) wide. * The heart in R10-03259 is a depression located near 22.7N, 56.6W, and is about 378 m (1,240 ft) wide. * The heart in R09-02121 is a small mesa on a...

The story of the Mars Orbiter Camera (MOC) onboard the Mars Global Surveyor(MGS) spacecraft began with a proposal to NASA in 1985. The first MOC flew on Mars Observer, a spacecraft that was lost before it reached the red planet in 1993. Now, after 14 years of effort, a MOC has finally been placed in the desired mapping orbit. The MOC team's happiness is perhaps best expressed by the planet Mars itself. On the first day of the Mapping Phase of the MGS mission--during the second week of March...

On January 26, 2001, the Kachchh region in western India suffered the most deadly earthquake in India's history. Shortly thereafter, geologists traversed the region looking for ground surface disruptions, such as fault breaks, that could provide clues to the tectonic processes here. Shuttle Radar Topography Mission (SRTM) scientists provided stereoscopic images to the geologists, similar to this 3-D view of the terrain northwest of the city of Bhuj. The geologists reported back that the images...

Several small-scale spots evident at around 37 north move in an easterly jet at a speed approaching 15 meters-per-second (33 mph). Toward the boundary with the white cloud band are several cloud strands that mark part of the westerly flow of the atmosphere. This flow reaches a maximum in the ?ribbonlike? structure, with...

The bright feature, slightly south of center is interpreted to be a volcano, 15-20 kilometers (9.3 to 12.4 miles) in diameter with a large apron of blocky debris to its right and some smaller aprons to its left.

The extreme contrast in this view of the unlit side of Saturn's rings is intentional. Contrast-enhanced views like this are used to look for spokes (the transient, ghostly lanes of dust seen in NASA Voyager and Hubble Space Telescope images), but so far, none have been seen by Cassini. The apparent absence of spokes is thought to be related to the Sun's elevation angle above the ringplane, which currently is rather high. As summer wanes in the southern hemisphere, the Sun's angle will drop, and...

The picture was taken on February 25, 1995, when Mars was at a distance of approximately 65 million miles (103 million km) from Earth. Because it is spring in Mars' northern hemisphere, much of the carbon dioxide frost around the permanent water-ice cap has sublimated, and the cap has receded to a core of solid water-ice...

On May 18, 1980, Mount St. Helens catastrophically erupted, causing the worst volcanic disaster in the recorded history of the United States. An earthquake shook loose the northern flank of the volcano, and about 2.8 cubic kilometers (0.67 cubic miles) of rock slid downslope in the world's largest recorded landslide. The avalanche released pressure on the volcano and unleashed a huge explosion, which was directed generally northward. The mountain ultimately lost 227 meters (1314 feet) of its...

The dunes are--ever so slowly--moving east to west (right to left) as sand avalanches down the steeper, slip face slopes of each. Avalanching sand in the Kaiser dune field has left deep scars on these slopes, suggesting that the sand is not loose but is instead weakly cemented.

These images taken through the wide angle camera near closest approach in the deep near-infrared methane band, combined with filters which sense electromagnetic radiation of orthogonal polarization, show that the light from the poles is polarized. That is, the poles appear bright in one image, and dark in the other. Polarized light is most readily scattered by aerosols. These images indicate that the aerosol particles at Jupiter's poles are small and likely consist of aggregates of even smaller...

NASA's Voyager 1 took this photograph of Saturn on Oct. 18, 1980,34 million kilometers (21.1 million miles) from the planet. The photograph was taken on the last day that Saturn and its rings could be captured within a single narrow-angle camera frame as the spacecraft closed in on the planet for its nearest approach on Nov. 12. Dione, one of Saturn's inner satellites, appears as three color spots just below the planet's south pole. An abundance of previously unseen detail is apparent in the...

Center of the orthographic projection is at latitude 30 degrees N., longitude 150 degrees. The north polar residual ice cap, which is cut by spiral-patterned troughs and surrounded by the dark lowland plains of Vastitas Borealis, is located at the top. The right-central part is dominated by the Tharsis Montes volcanoes. The most prominent of the Tharsis Montes volcanoes is the largest known volcano in the solar system, Olympus Mons. The light-colored lowland plains of Amazonis, Elysium, and...

This view of northern Patagonia, near El Cain, Argentina shows complexly eroded volcanic terrain, with basalt mesas, sinkholes, landslide debris, playas, and relatively few integrated drainage channels. Surrounding this site (but also extending far to the east) is a broad plateau capped by basalt, the Meseta de Somuncura. Here, near the western edge of the plateau, erosion has broken through the basalt cap in a variety of ways. On the mesas, water-filled sinkholes (lower left) are most likely...

This infrared image from NASA's Spitzer Space Telescope shows the Orion nebula, our closest massive star-making factory, 1,450 light-years from Earth. The nebula is close enough to appear to the naked eye as a fuzzy star in the sword of the popular hunter constellation. The nebula itself is located on the lower half of the image, surrounded by a ring of dust. It formed in a cold cloud of gas and dust and contains about 1,000 young stars. These stars illuminate the cloud, creating the beautiful...

NASA's Spitzer Space Telescope recently captured these images of the star Vega, located 25 light years away in the constellation Lyra. Spitzer was able to detect the heat radiation from the cloud of dust around the star and found that the debris disc is much larger than previously thought. This side by side comparison, taken by Spitzer's multiband imaging photometer, shows the warm infrared glows from dust particles orbiting the star at wavelengths of 24 microns (figure 2 in blue) and 70...

Manicouagan Crater is one of the world's largest and oldest known impact craters and perhaps the one most readily apparent to astronauts in orbit. The age of the impact is estimated at 214 million years before present. Since then erosion has removed about one kilometer (0.6 miles) of rock from the region and has created a topographic pattern that follows the structural pattern of the crater. A ring depression (prominently seen as green) encloses a central peak. The ring depression now hosts the...
