Jupiter10	Another view of Io.
Jupiter11	Changes on Io's surface caused by volcanic activity. The left image was taken by the Voyager spacecraft in 1979. The right image was taken by the Galileo spacecraft in September, 1996.
Jupiter12	Changes in the volcano Prometheus. The left image was taken by the Voyager spacecraft in 1979. The right image was taken by the Galileo spacecraft in September, 1996. A new dark lava flow has developed.
Jupiter13	Changes in the volcano Pele. Left image: Voyager 1 in 1979. Middle image: Voyager 2 in 1979. Right image: Galileo in June, 1996.
Jupiter14	This image taken by the Galileo spacecraft in November, 1996 shows the red circular plume deposit from the volcano Pele. Pele has ejected sulfurous materials out to distances more than 600 km (370 miles)!
Jupiter15	Changes in the volcano Loki Patera. Upper left: Voyager1, 1979. Upper right: Voyager 1, color. Lower left: Voyager 2, color. Lower left: Galileo, June, 1996. The area is about 560 miles wide.
Jupiter16	Four views of active volcanic plumes as Io rotates. The plumes rise to a height of about 60 miles.
Jupiter17	A plume 86 miles high erupts over the volcano Pillan Patera. The Galileo spacecraft took this image from a distance of 372,000 miles on June 28, 1997.
Jupiter18	A volcanic plume rising 60 miles above the Masubi region of Io. The plume appears blue because of the way small particles in the plume scatter light. The image was taken by the Galileo spacecraft on July 3, 1999 from a distance of 81,000 miles.
Jupiter19	This lava fountain on Io was so hot and bright that it saturated the camera producing white blurs. The lava shoots about a mile high out of a long crack on the surface. Initial estimates of the lava temperature indicate that it is well above 1,000 Kelvin (1,300 Fahrenheit) and might even be hotter than 1,600 Kelvin (2,400 Fahrenheit). The area shown is about 190 by 47 miles. The image was taken on November 25, 1999 by the Galileo spacecraft from a distance of 11,000 miles.
Jupiter20	An artist's representation of the Io lava fountain.
Jupiter20a	An active volcanic caldera on Io! The caldera is called Tupan Patera and is 75 km across. It is a depression surrounded by cliffs nearly one km high. The image shows hot black lava, warm red sulfur deposits probably caused by vented gas, and yellow terrain also high in sulfur. The image is from the Galileo spacecraft.
Jupiter21	A comparison of the surfaces of the four Galilean moons.
Jupiter22	Jupiter's moon Europa. The left image is in natural color. The right image is in enhanced color. Dark brown areas represent rocky material derived from the interior, implanted by impact, or from a combination of interior and exterior sources. Bright plains in the polar areas (top and bottom) are shown in tones of blue to distinguish possibly coarse-grained ice (dark blue) from fine-grained ice (light blue). Long, dark lines are fractures in the crust, some of which are more than 3,000 kilometers (1,850 miles) long. The bright feature containing a central dark spot in the lower third of the image is a young impact crater some 50 kilometers (31 miles) in diameter. This crater has been provisionally named 'Pwyll' for the Celtic god of the underworld. Europa is about 3,160 kilometers (1,950 miles) in diameter, or about the size of Earth's moon. This image was taken on September 7, 1996, at a range of (417,900 miles) by the Galileo spacecraft.
Jupiter23	Another view of Europa.
Jupiter24	The Pwyll impact crater on Europa is about 16 miles in diameter. The bright rays extend over 600 miles in all directions and lie on top of surface which existed before the impact.
Jupiter25	A closer view of the Pwyll impact crater.
Jupiter26	The Tyre impact crater on Europa is about 86 miles in diameter.
Jupiter27	These small craters on Europa lie within one of the bright rays from the large crater Pwyll, so they are probably caused by material Pwyll ejected. The diameters range from 30 meters to over 450 meters.
Jupiter28	This area about 780 miles across is shown in enhanced color to increase the visibility of linear features on Europa. Brown and reddish hues indicate the presence of contaminants in the water ice.
Jupiter29	Linear features cross this 500 by 220 mile area on Europa. Blue colors indicate almost pure water ice.
Jupiter30	Ice floes (sheets of floating ice) were formed on Europa when fractures broke the crust into plates as large as 18.5 miles across. This area is 310 by 600 miles.
Jupiter31	A high resolution image of one of Europa's linear features called Agenor Linea. The area shown is 80 by 60 miles.
Jupiter32	Ridged plains on Europa. The most prominent ridges are about .6 miles wide. This image was taken by the Galileo spacecraft on December 16, 1997 from a distance of 800 miles. The area shown is 9 by 12 miles.
Jupiter33	The bright left to right ridge is about 3.1 miles wide. It is younger than the darker disrupted vertically oriented ridge.
Jupiter34	A young ridge 1.6 miles wide and about 300 meters high is shown in this 8.7 by 10.6 mile image of Europa.
Jupiter35	Ice rafts on Europa! The area shown is 44 by 19 miles. The white and blue enhanced colors come from a fine dust of ice particles ejected by a distant impact crater.
Jupiter36	A closer view of the ice rafts! Some of these are up to 8 miles across. They resemble pack ice on polar seas following spring thaws on Earth. The size of this jigsaw puzzle is 21 by 26 miles.
Jupiter37	The highest resolution image of Europa shows an area only one mile wide! This was taken by the Galileo spacecraft on December 16, 1997 from a distance of 335 miles.
Jupiter38	Two proposed models for the interior of Europa.
Jupiter39	Jupiter's Moon Ganymede.
Jupiter40	Another view of Ganymede. Colors are enhanced to emphasize color differences.
Jupiter41	Two dark-floored craters on Ganymede. The left crater is 3.7 miles in diameter, and the right crater is 7.5 miles in diameter. Bright icy material is exposed on the walls, rims, and peaks.
Jupiter42	Two fresh impacts on Ganymede. Many smaller secondary impacts are seen. The top crater is 24 miles across, and the bottom crater is 20 miles across.
Jupiter43	A chain of 13 craters thought to have been formed by the impact of a fragmented comet. The image area is 133 by 135 miles.
Jupiter44	Ice hills and valleys on Ganymede. Objects as small as 11 meters can be seen. In the left image the bright sides of hills face the Sun. The right image has been processed to bring out details in the shadows. The bright hillsides are then overexposed.
Jupiter45	Ridges and grooves on Ganymede here occupy an area 50 by 36 miles.
Jupiter46	An interesting intersection of two different types of terrain on Ganymede. The area is 590 by 348 miles.
Jupiter47	The proposed model of Ganymede's interior.
Jupiter48	Jupiter's moon Callisto.
Jupiter49	Four images of Callisto's surface at increasing resolution.
Jupiter50	This portion of a chain of craters on Callisto was probably formed by a fragmented projectile. The area imaged is 28 miles across.
Jupiter51	A fault scarp on Callisto casts a shadow to the right. The area is 20 miles across.
Jupiter52	These two craters on Callisto have fan-shaped landslide deposits about 1.8 to 2.1 miles long. The landslides are partially in shadow. The area shown is 33 by 26 miles.
Jupiter53	Proposed models of the interiors of all four Galilean moons.
Jupiter54	Jupiter's ring imaged by the Galileo spacecraft on November 9, 1996. Note the dark bands on the right edge.
Jupiter55	Another view of Jupiter's ring. The apparently missing ring segment at lower right lies in Jupiter's shadow.
Jupiter56	This schematic cut-away view of the components of Jupiter's ring system shows the geometry of the rings in relation to Jupiter and to the small inner satellites, which are the source of the dust which forms the rings. The innermost and thickest ring, shown in gray shading, is the halo that ends at the main ring. The thin, narrow main ring, shown with red shading, is bounded by the 16-kilometer-wide (10-miles) satellite Adrastea and shows a marked decrease in brightness near the orbit of Jupiter's innermost moon, Metis. It is composed of fine particles knocked off Adrastea and Metis. Although the orbits of Adrastea and Metis are about 1,000 kilometers (about 600 miles) apart, that separation is not depicted in this drawing. Impacts by small meteoroids (fragments of asteroids and comets) into these small, low-gravity satellites feed material into the rings. Thebe and Amalthea, the next two satellites in increasing distance from Jupiter, supply dust which forms the thicker, disk-like "gossamer" rings. The gossamer rings, depicted with yellow and green shading, are thicker because the source satellites orbit Jupiter on inclined paths
Jupiter57	This Hubble Telescope image of comet P/Shoemaker-Levy 9 on May 17, 1994 shows 21 fragments spread out across 1.1 million km (710,000 miles) before the comet’s collision with Jupiter in July of 1994.
Jupiter58	Hubble Telescope color image of the impact sites of comet fragments G and Q2 on July 20, 1994.
