Jupiter's Moons and Comet Images

A collection featuring images of Jupiter's moons, Europa, Ganymede, and Callisto, alongside the comet Tempel 1, showcasing their unique surface features and textures.

Range : 5.9 million kilometers (3.66 million miles) Europa is Jupiter's 2nd Galilean satellites from the planet and the brightest. Photo taken early morning through violet filter. Faint swirls and linear patterns show in the equatorial region (which shows darker than the poles). This hemisphere always faces Jupiter. North is up. Density and size comparable to Earth's Moon and seems to show water ice or ground water on its surface.

The south pole, continuously illuminated by sunlight at this season, ia at bottom left. the boundary between bright southern hemisphere and the darker and the darker, northern hemisphere is clearly visible. Both the darker regions to the north and the very bright sub-equatorial band show a complex pattern of irregular topography that somewhat resembles 'fretted terrain' on parts of Venus and Mars. The pattern of dark and light regions over most of the southern hemisphere will require higher resolution images for interpretation. Also evident are long, straight lines that appear to be surface expressions of internal, tectonic processes. No large impact ctaters are visible, suggesting that the crust of Triton has been renewed relatively recently, that is, within the last bllion years or les

Range 168,694 km (105,000 mi.) Voyager 2 discovered detached limb hazes in the atmosphere of Triton in Pictures that arrived at Earth between 3 30 am and 5 30 am. The principal layer seen here begins about three km (2 miles) above the surface, and is about 3 km thick. Fainter upward extension of the haze has been seen to an altitude of at least 14 km (9 mi.). The haze must be comoposed of tiny particles in order to be supported in Trition's thin atmosphere. Composition of the haze is currently unknown, but may be either condensed atmospheric gases or complex orgainc molecules produced by irradiation of the methane in Triton's atmosphere. The vaguely linear mottling on the surface may be shadows of other haze striations. Other features of the haze layer should be appaarent in images of Triton taken at higher phase angles (including crescent phase). The image shows features as small as 2 km (1.2 mi) wide.

NASA's Planetary Radar Images Asteroid 2006 HV5. This collage represents a selection of NASA radar observations of near-Earth asteroid 2006 HV5 on April 25, 2023, less than one day before its close approach with our planet at a distance of about 1.5 million miles (2.4 million kilometers, or about 6.3 times the distance between the Moon and Earth). Asteroid 2006 HV5 was discovered by the Lincoln Near-Earth Asteroid Research (LINEAR) program in New Mexico in April 2006. The radar images show that 2006 HV5 is about 1,000 feet (300 meters) across, roughly the height of the Eiffel Tower, confirming size estimates derived from infrared observations made previously by NASA's NEOWISE mission. 2006 HV5 is classified as a potentially hazardous asteroid as its orbit brings it close to Earth, but its path around the Sun is very well known and the asteroid is not an impact risk to our planet. Asteroids of this size come this close to Earth roughly once a year, on average. The new observations were

This image is the first full picture showing both asteroid 243 Ida and its newly discovered moon to be transmitted to Earth from NASA's Galileo spacecraft--the first conclusive evidence that natural satellites of asteroids exist. Ida is the large object to the left, about 56 kilometers (35 miles long). Ida's natural satellite is the small object to the right. This portrait was taken by Galileo's charge-coupled device (CCD) camera on August 28, 1993, about 14 minutes before the spacecraft's closest approach to the asteriod, from a range of 10,870 kilometers (6,755 miles). Ida is a heavily cratered, irregularly shaped asteroid in the main asteroid belt between Mars and Jupiter-- the 243rd asteroid to be discovered since the first one was found at the beginning of the 19th century. It is a member of a group of asteroids called the Koronis family. The small satellite, which is about 1.5 kilometers (1 mile) across in this view, has yet to be given a name by astronomers. It has been provisio

P-29479B/W This Voyager 2 image of the brightest Uranian satellite of the five largest, Ariel, was shot through a clear filter with the narrow angle camera. Ariel is about 1,300 km. ( 800 mi. )in diameter. This image shows several distinct bright areas that reflect nearly 45 % of the incident sunlight. On average, the satellite displays reflectivity of about 25-30 %. The bright areas are probably fresh water ice, perhaps excavated by impacts. the south pole of Ariel is slightly off center of the disk in this view.

6145-44734563
Range 7 million kilometers (4.3 million miles) Io is Jupiter's innermost of the four Galilean satellites. Photo taken at 2 00 AM through an ultraviolet filter. The photo's background is part of Jupiter's disk. North is at the top and the central longitude of Io is 180 degrees. Io shows a contrasting surface with dark polar areas and many light and dark regions around the equator. This resolution of about 100 miles/160 kilometers, no topographic features, like craters, can be seen. The brighter regions may be areas containing sulfur and various salts, making Io very reflective(six times brighter thanb Earth's Moon). Io is about the same size and density as our Moon, but has followed a different evolutionary path, influenced by its closeness to Jupiter and the intense bombardment it receives from the Jovian radiation belts of energetic charged particles.

This photomosaic of Triton, assembled from 14 individual frames, shows the great variety of its surface features. At the bottom of the image are remnants of the south polar cap, containing 'dark' streaks generally aligned towards the northeast (upper right in the image). Even though these are darker than other features on Triton, they reflect nearly ten times as much light as the surface of the Earth's moon. North of the cap, in the western (left) half of the disk is the region which has been informally dubbed the 'cantaloupe' terrain. Small dimples with upraised rims and shallow central depressions dot the area. Long fractures have opened allowing some icy material to ooze up and form a central ridge. These criss-cross the region and extend into parts of the polar cap region. Towards the south this terrain has a light covering of frost. Running east to the limb of Triton, just north of the polar cap, is an area of smooth plains and low hills which is the most densely cratered region s

Callisto, the darkest of the Galilean Satellites, still nearly twice as bright as the Earth's Moon, is seen here from the face that always faces Jupiter. All of the Galilean Satellites always show the same face to Jupiter, as the Earth's moon does to Earth. The Surface shows a mottled appearance of bright and dark patches. The former reminds scientists of rayed or bright haloed craters, similiar to those seen on earth's Moon.

P-29511 BW Range 130,000 kilometers (80,000 miles) This clear-filter, narrow-angle picture is part of the high-resolution Voyager 2 imaging sequence of Ariel, a moon of Uranus about 1,300 kilometers (800 miles) in diameter. The complexity of Ariels' surface indicates that a variety of geologic processes have occured. The numerous craters, for example, are indications of an old surface bombarded by meteroids over a long periond. Also conspicuous at this resolution, about 2.4 km (1.5 mi), are linear grooves (evidence of tectonic activity that has broken up the surface) and smooth patches (indicative of deposition of material).

The southern hemisphere appears lighter in contrast, a well defined band is seen near the equator, and a dark collar is evident at the north pole. All these bands are associated with the cloud circulation in titan's atmosphere. The extended haze, composed of of sub-micron size particles, is seen clearly around the satellite's limb. This image was composed from blue, green, and violet frames.

Range 4 million km. ( 2.5 million miles ) P-34654 This Voyager 2 image of Neptune's satteltite Triton was made by combining images taken through the green, clear, and violet filters. The smallest feature seen are about 74 km, or 46 miles accross. The south pole of Triton is currently tipped toward the sun and it is summer in the southern hemisphere. The south pole is located about a quarter of the way up from the bottom if the image. The bright band near the top of the image nearly coincides with the equator of Triton. One prominent and several smaller bright, wispy streaks extend from the band into the darker northern hemisphere. The prominent wispy streak shows bluish-white color, while the darker northern hemisphere is reddish in color. This may indicate that the streak is freshly deposited frost while the red color in the northern hemisphere may result from methane frost that has been darkened by radiation. Individual markings appear to rotate with the satellite and retain their sh

P-29518 BW Range 130,000 kilometers (80,000 miles) This highest-resolution Voyager 2 view of Ariel's terminator shows a complex array of transecting valleys with superimposed impact craters. This clear-filter, narrow-angle view has a resolution of about 2.4 km (1.5 mi). Particularly striking to Voyager scientists is the fact that the faults that bound the linear valleys are not visible where they transect one another across the valleys. Apparently these valleys were filled with deposits sometime after they were formed by tectonic processes, leaving them flat and smooth. Sinuous rilles (trenches) later formed, probably by some flow process. Some type of fluid flow may well have been involved in their evolution.

P-29521 BW Range 557,000 kilometers ( 346, 000 miles) The southern hemisphere of Umbriel displays heavy cratering in this Voyager 2 image. This frame, taken through the clear-filter of Voyager's narrow-angle camera, is the most detailed image of Umbriel, with a resolution of about 10 km (6 mi). Umbriel is the darkest of Uranus' larger moons and the one that appears to have experienced the lowest level of geological activity. It has a diameter of about 1,200 km (750 mi) and reflects only 16 percent of the light striking its surface; in the latter respect, Umbriel is similiar to lunar highland areas. Umbriel is heavily cratered but lacks the numerous bright-ray craters seen on the other large Uranian satellites; this results in a relatively uniform surface albedo (reflectivity). The prominent crater on the terminator (upper right) is about 110 km (70 mi) across and has a bright central peak. The strangest feature in this image (at top) is a curious bright ring, the most reflective area s
