Range :  1,450,000 km. ( 900,000 miles ) Jupiter's faint ring system is shown here as two orange lines protrude from the left toward Jupiter's limb.  This colorful composite was taken in Jupiter's shadow through orange and violet filters. The colorful images of Jupiter's limb are evidence of the spacecraft motion dering this long exposure.  Voyager 2 was about 2 degrees below the plane of the ring when this was shot, leaving the lower ring image cut short by Jupiter's shadow on the ring. (JPL ref No. P-21779) ARC-1979-AC79-7117

4.17 million miles (2.59 million miles) Resolution :  40 km. (25mi.) P-29498C This false color, Voyager 2 composite view of all nine of Uranian rings  was made from six 15 second exposures through the narrow angle camera. The special computer processing  used to extract color information from the extremely dark and faint rings, causing the even fainter, pastel lines seen between the rings. Two images, each in the green, clear, & violet filters, were added together and averaged to find the proper color difference between the rings. the final image was made from these three color averages and represents an enhanced, false color view. The image shows that the brightest, or Epsilon ring, at top ,is neutral in color, with the fainter eight other rings showing color differences between them. moving down, toward, Uranus, we see the Delta, Gamma, & Eta rings in shades of blue and green; the Beta & Alpha rings in somewhat lighter tones; and then finally, a set of three, known simply as 4, 5, & 6 rings, in faint off-white tones. Scientists will use this color information to try to understand the nature and origin of the ring material. ARC-1986-AC86-7015

Range :  170,000 km. ( 105,000 mi. ) Resolution :  3 km. ( 2 mi. ) P-29523C This Voyager 2 photograph of the Uranian Moon Ariel, is the best quality to date. This view of Ariel's southern hemisphere is a composite of photographs taken through green, blue, and violet filters from the narrow angle camera. Most of the visible surface consists of relatively intensely cratered terrain transected by fault scarps and fault bounded valleys (graben). Some of the largest valleys, which can be seen  near the terminator (at right), are partly filled with younger deposits that are less heavily cratered. Bright spots near the limb and toward are chiefly the rims of small craters. Most of the brightly rimmed craters are too small to be resolved here, although one about 30 km. (20 mi.) in diameter can be easily distiguished near the center. These bright-rim craters, thogh the youngest features on Ariel, probably have formed over a long span of geological tome. Although Ariel has a diameter of abou 1,200 km. ( 750 mi. ), it clearly experienced a great deal of geological activity in the past. ARC-1986-AC86-7039

Range :  14.8 million km. ( 9.2 million miles) P-34595C This contrast enhanced color photograph of Neptune was produced from images taken through the orange, green, and violet filters of the narrow angle camera. As Voyager 2 approaches Neptune, rapidly increasing image resolution is revealing striking new details in the planet's atmosphere, and this pictureshows features as small as a few hundred kilometers in extent. Bright, wispy  'cirrus-type' clouds are seen overlying the Great Dark Spot (GDS) at its southern (lower) margin and over its northwest ( upper left) boundary. This is the first evidence that the GDS lies lower in the atmosphere  than these bright clouds, which have remained in its vicinity for several months. Increasing detail in global banding, and the south polar can also be seen. A smaller dark spot  at high southern latitudes  is dimly visible near the limb at lower left. ARC-1989-AC89-7043

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 shapes indicating they are indeed surface features and not in the tenuous atmosphere. ARC-1989-AC89-7016

Range :  35,000 miles plus. This color image of the Simpson Desert in Australia was obtained by the Galileo spacecraft at aboaut 2:30 pm PST.  The color composite was made from images taken through the red, green and violet filters.  The area shown, about 280 miles wide by about 340 miles north-to-south, is southeast of Alice Springs.  At lower left is Lake Eyre, a salt lake below sea level, subject to seasonal water-level fluctuations; when this image was acquired the lake was nearly dry.  At lower right is the greenish Lake Blanche.  Fields of linear sand dunes stretch north and east of Lake Eyre, shaped by prevailing winds from the south and showing, in different colors, the various sources and/or ages of their sands.

ref # P-37330 Range :  1.3 million miles This color image of the Earth was obtained by the Galileo spacecraft at about 6:10 am PST.  The color composite used images taken through the red, green and violet filters.  South America is near the center of the picture, and the white, sunlit continent of Antarctica is below.  Picturesque weather fronts are visible in the South Atlantic, lower right.  This is the first frame of the Galileo Earth spin movie, a 500-frame time-lapse motion picture showing a 25-hour period of Earth's rotation and atmosphertic dynamics. ARC-1990-AC91-2008

This color picture of the limb of the Earth, looking north past Antarctica, is a mosaic of 11 images taken during a ten-minute period near 5:45 p.m. PST Dec. 8, 1990, by Galileo's imaging system.  Red, green and violet filters were used.  The picture spans about 1,600 miles across the south polar latitudes of our planet  The morning day/night terminator is toward the right.  The South Pole is out of sight below the picture;  the visible areas of Antarctica are those lying generally south of South America.  The violet-blue envelope of Earth's atmosphere is prominent along the limb to the left.  At lower left, the dark blue Amundsen Sea lies to the left of the Walgreen and Bakutis Coasts.  Beyond it,  Peter Island reacts with the winds to produce a striking pattern of atmosperic waves. (JPL ref. No. P-37340) ARC-1990-AC91-2017
