<h1>PIA00011: Cylindrical Projection of Jupiter</h1><div class="PIA00011" lang="en" style="width:800px;text-align:left;margin:auto;background-color:#000;padding:10px;max-height:150px;overflow:auto;">This computer generated map of Jupiter was made from 10 color images of Jupiter taken Feb. 1, 1979, by Voyager 1, during a single, 10 hour rotation of the planet. Computers at Jet Propulsion Laboratory's Image Processing Lab then turned the photos into this cylindrical projection. Such a projection is invaluable as an instantaneous view of the entire planet. Along the northern edge of the north equatorial belt (NEB) are four dark brown, oblong regions believed by some scientists to be openings in the more colorful upper cloud decks, allowing the darker clouds beneath to be seen. The broad equatorial zone (EZ) is dominated by a series of plumes, possibly regions of intense convective activity, encircling the entire planet. In the southern hemisphere the Great Red Spot is located at about 75 degrees longitude. South of the Great Red Spot in the south temperate zone (STeZ) three large white ovals, seen from Earth-based observatories for the past few decades, are located at 5 degrees, 85 degrees and 170 degrees longitude. Resolution in this map is 375 miles (600 kilometers). Since Jupiter's atmospheric features drift around the planet, longitude is based on the orientation of the planet's magnetic field. Symbols at right edge of photo denote major atmospheric features (dark belts and light zones): NTeZ - north temperate zone; NTrZ - north tropical zone; NEB - north equatorial belt; EZ - equatorial zone; SEB - south equatorial belt; STrZ - south tropical zone; and STeZ - south temperate zone.

<h1>PIA00014: Jupiter Great Red Spot</h1><div class="PIA00014" lang="en" style="width:800px;text-align:left;margin:auto;background-color:#000;padding:10px;max-height:150px;overflow:auto;">This dramatic view of Jupiter's Great Red Spot and its surroundings was obtained by Voyager 1 on Feb. 25, 1979, when the spacecraft was 5.7 million miles (9.2 million kilometers) from Jupiter. Cloud details as small as 100 miles (160 kilometers) across can be seen here. The colorful, wavy cloud pattern to the left of the Red Spot is a region of extraordinarily complex end variable wave motion.

Features of this sort are not rare on Jupiter and have an average lifetime of one to two years. Above the feature is the pale orange North Temperate Belt, bounded on the south by the high speed North Temperate Current with winds of 120 meters/sec (260 mi/hr). The range to Jupiter at the time this photograph was obtained was 4.0 million kilometers (2.5 million miles) with the smallest resolvable features being 75 kilometers (45 miles) wide.

Distance from top to bottom of the picture is 15,000 miles (24,000 kilometers). Smallest features visible are about 20 miles (30 kilometers) across. The white feature below the Great Red Spot is one of several white ovals that were observed to form about 40 years ago; they move around Jupiter at a different velocity from the Red Spot. During the Voyager 1 encounter period, material was observed to revolve around the center of the spot with a period of six days.

<h1>PIA00029: First Close-up Image of Jupiter from Voyager 1</h1><div class="PIA00029" lang="en" style="width:400px;text-align:left;margin:auto;background-color:#000;padding:10px;max-height:150px;overflow:auto;">NASA'S Voyager 1 took this picture of the planet Jupiter on Saturday, Jan. 6, the first in its three-month-long, close-up investigation of the largest planet. The spacecraft, flying toward a March 5 closest approach, was 35.8 million miles (57.6 million kilometers) from Jupiter and 371.7 million miles (598.2 million kilometers) from Earth when the picture was taken. As the Voyager cameras begin their meteorological surveillance of Jupiter, they reveal a dynamic atmosphere with more convective structure than had previously been thought. While the smallest atmospheric features seen in this picture are still as large as 600 miles (1,000 kilometers) across, Voyager will be able to detect individual storm systems as small as 3 miles (5 kilometers) at closest approach. The Great Red Spot can be seen near the limb at the far right. Most of the other features are too small to be seen in terrestrial telescopes. This picture is really a combination of three images taken through color filters, then transmitted to Jet Propulsion Laboratory through the Deep Space Network's antennas, and assembled by JPL's Image Processing Lab. The Voyager Project is managed for NASA by Caltech's Jet Propulsion Laboratory.<br /><br /><a href="http://photojournal.jpl.nasa.gov/catalog/PIA00029" onclick="window.open(this.href); return false;" title="Voir l'image PIA00029: First Close-up Image of Jupiter from Voyager 1 sur le site de la NASA">Voir l'image PIA00029: First Close-up Image of Jupiter from Voyager 1 sur le site de la NASA.</a></div>

<h1>PIA00139: Comet Shoemaker-Levy 9 Fragment W Impact With Jupiter</h1><div class="PIA00139" lang="en" style="width:800px;text-align:left;margin:auto;background-color:#000;padding:10px;max-height:150px;overflow:auto;">These four images of Jupiter and the luminous night-side impact of fragment W of Comet Shoemaker-Levy 9 were taken by the Galileo spacecraft on July 22, 1994. The spacecraft was 238 million kilometers (148 million miles) from Jupiter at the time, and 621 million kilometers from Earth. The spacecraft was about 40 degrees from Earth's line of sight to Jupiter, permitting this direct view. The images were taken at intervals of 2 1/3 seconds, using the green filter (visible light). The first image, taken at an equivalent time to 8:06:10 Greenwich Mean Time (1:06 a m. Pacific Daylight Time), shows no impact. In the next three images, a point of light appears, brightens so much as to saturate its picture element, and then fades again, seven seconds after the first picture. The location is approximately 44 degrees south as predicted, dark spots to the right are from previous impacts. Jupiter is approximately 60 picture elements in diameter. Galileo tape-recorded most of its observations of the Shoemaker-Levy events during the second week of July 1994 and has since been playing the tape back selectively. Many more pictures and data from other instruments remain to be returned from the spacecraft's tape recorder. Playbacks will continue through January 1995. It is not yet certain whether the data relate to meteor bolides (the comet fragment entering Jupiter's atmosphere) or to the subsequent explosion and fireball. Once all the Galileo, Hubble Space Telescope and groundbased data are integrated, an excellent start-to-finish characterization of these remarkable phenomena will be available. The Galileo project, whose primary mission is the exploration of the Jupiter system in 1995 through 1997, is managed by the Jet Propulsion Laboratory for NASA's Office of Space Science.<br /><br /><a href="http://photojournal.jpl.nasa.gov/catalog/PIA00139" onclick="window.open(this.href); return false;" title="Voir l'image PIA00139: Comet Shoemaker-Levy 9 Fragment W Impact With Jupiter sur le site de la NASA">Voir l'image PIA00139: Comet Shoemaker-Levy 9 Fragment W Impact With Jupiter sur le site de la NASA.</a></div>

<h1>PIA00144: Jupiter with Satellites Io and Europa</h1><div class="PIA00144" lang="en" style="width:800px;text-align:left;margin:auto;background-color:#000;padding:10px;max-height:150px;overflow:auto;">Voyager 1 took this photo of Jupiter and two of its satellites (Io, left, and Europa) on Feb. 13, 1979. Io is about 350,000 kilometers (220,000 miles) above Jupiter's Great Red Spot; Europa is about 600,000 kilometers (375,000 miles) above Jupiter's clouds. Although both satellites have about the same brightness, Io's color is very different from Europa's. Io's equatorial region show two types of material -- dark orange, broken by several bright spots -- producing a mottled appearance. The poles are darker and reddish. Preliminary evidence suggests color variations within and between the polar regions. Io's surface composition is unknown, but scientists believe it may be a mixture of salts and sulfur. Europa is less strongly colored, although still relatively dark at short wavelengths. Markings on Europa are less evident than on the other satellites, although this picture shows darker regions toward the trailing half of the visible disk. Jupiter is about 20 million kilometers (12.4 million miles) from the spacecraft. At this resolution (about 400 kilometers or 250 miles) there is evidence of circular motion in Jupiter's atmosphere. While the dominant large-scale motions are west-to-east, small-scale movement includes eddy-like circulation within and between the bands. This photo was assembled from three black and white negatives by the Image Processing Lab at Jet Propulsion Laboratory.

<h1>PIA00204: Lights In The Night</h1><div class="PIA00204" lang="en" style="width:800px;text-align:left;margin:auto;background-color:#000;padding:10px;max-height:150px;overflow:auto;">LIGHTS IN THE NIGHT ON JUPITER: This Voyager 1 image was taken of Jupiter's darkside on March 5, 1979. The picture is a 3 minute, 12 second exposure by the wide angle camera taken when the spacecraft was in Jupiter's shadow, about 6 hours after closest approach to the planet at a distance of 320,000 miles. Jupiter's north pole is on the limb toward the upper center. The long bright double streak is an aurora on Jupiter's limb near its north pole. The other bright spots probably are lightning but could be auroral features. The aurora s structure may be real or it may be caused by scan platform stepping during the exposure. The diagonal displacement of bright spots within each of the three active regions is due generally to the scan platform stepping; but the patterns do not reproduce in detail nor do they exhibit exactly the displacements of the camera during the exposure. As lightning flashes they are comparable to the brightness of superbolts seen at the tops of terrestrial tropical thunderstorms. As auroral features they would be required to be much brighter than those on Earth.<br /><br /><a href="http://photojournal.jpl.nasa.gov/catalog/PIA00204" onclick="window.open(this.href); return false;" title="Voir l'image PIA00204: Lights In The Night sur le site de la NASA">Voir l'image PIA00204: Lights In The Night sur le site de la NASA.</a></div>

<h1>PIA00235: Jupiter with Satellite Io</h1><div class="PIA00235" lang="en" style="width:800px;text-align:left;margin:auto;background-color:#000;padding:10px;max-height:150px;overflow:auto;">Voyager 1 took this photo of Jupiter Feb. 1, 1979, at a range of 20 million miles (32.7 million kilometers). Voyager scientists can now see that different colors in clouds around the Great Red Spot imply that the clouds swirl around the spot at varying altitudes. They also observe apparently regular spacing between the small white spots in the southern hemisphere and similar positioning of dark spots in the northern hemisphere. A major activity will be to understand the form and structure of the spots and how they may relate to interactions between the atmospheric composition and its motions. When scientists compare this image with the 6,000 others already taken, they see many changes both large and small. The bright cloud in the equatorial region north of the Great Red Spot, for example, appears to be where bright clouds originate, then stream westward. On the other hand, the bright ovals south of the Great Red Spot were seen to form about 40 years ago, and have remained much the same ever since. The Great Red Spot itself has been observed for hundreds of years though never in the detail seen here. Objects as small as 375 miles (600 kilometers across can be seen in this image. That resolution is the best achieved of Jupiter. This black-and-white photo was taken through blue filter.

The colors have been enhanced to bring out detail. Zones of light-colored, ascending clouds alternate with bands of dark, descending clouds. The clouds travel around the planet in alternating eastward and westward belts at speeds of up to 540 kilometers per hour. Tremendous storms as big as Earthly continents surge around the planet. The Great Red Spot (oval shape toward the lower-left) is an enormous anticyclonic storm that drifts along its belt, eventually circling the entire planet.<br /><br /><a href="http://photojournal.jpl.nasa.gov/catalog/PIA00343" onclick="window.open(this.href); return false;" title="Voir l'image PIA00343: Jupiter sur le site de la NASA">Voir l'image PIA00343: Jupiter sur le site de la NASA.</a></div>

The spacecraft was 28.4 million kilometers (17.5 million miles) from the planet at the time. The innermost large satellite, Io, can be seen against Jupiter's disk. Io is distinguished by its bright, brown-yellow surface. To the right of Jupiter is the satellite Europa, also very bright but with fainter surface markings. The darkest satellite, Callisto (still nearly twice as bright as Earth's Moon), is barely visible at the bottom left of the picture. Callisto shows a bright patch in its northern hemisphere. All three orbit Jupiter in the equatorial plane, and appear in their present position because Voyager is above the plane. All three satellites show the same face to Jupiter always -- just as Earth's Moon always shows us the same face. In this photo we see the sides of the satellites that always face away from the planet. Jupiter's colorfully banded atmosphere displays complex patterns highlighted by the Great Red Spot, a large, circulating atmospheric disturbance. This photo was assembled from three black and white negatives by the Image Processing Lab at Jet Propulsion Laboratory.

The well defined pale orange line running from southwest to northeast (North is at the top) marks the high speed north temperate current with wind speeds of about 120 meters per second. These high winds produce a cleaner flow pattern in the surrounding clouds. Toward the top of the picture, a weaker jet of approximately 30 meters per second is characterized by wave patterns and cloud features which have been observed to rotate in a clockwise manner at these latitudes of about 35 North. These clouds have been observed to have lifetimes of about one to two years.

The Voyager spacecraft is rapidly nearing the giant planet, with closest approach to occur at 4:23 pm PDT on July 9. Seen in front of the turbulent clouds of the planet is Io, the innermost of the large Galilean satellites of Jupiter. Io is the size of our moon. Voyager discovered in early March that Io is the most volcanically active planetary body known in the solar system, with continuous eruptions much larger than any that take place on the Earth. The red, orange, and yellow colors of Io are thought to be deposits of sulfur and sulfur compounds produced in these eruptions. The smallest features in either Jupiter or Io that can be distinguished in this picture are about 200 kilometers (125 miles) across; this resolution, it is not yet possible to identify individual volcanic eruptions. Monitoring of the erupture activity of Io by Voyager 2 will begin about July 5 and will extend past the encounter July 9.

At this range, Voyager 1 is able to record more detail on the giant planet than the very best ground-based telescopes. The highest resolution ever obtained on the Jovian disk was recorded by Pioneer 11 four years ago. Voyager, however, has longer focal-length optics than Pioneer, and while nearly three months from encounter (~ March 1979) was able to achieve higher resolution than that obtained by Pioneer only 24 hours from its encounter on 3 December 1974.<p>Jupiter's colorful and turbulent atmosphere is evident in these photographs. The entire visible surface of the planet is made up of multiple layers of clouds, composed primarily of ammonia ice crystals colored by small amounts of materials of unknown composition. The Great Red Spot, seen to the lower left of 2 and lower right of 3, is now recovering from a period of relative inconspicuousness. An atmospheric system larger than the Earth and more than 100 years old, the Great Red Spot remains a mystery and a challenge to Voyager instruments. A bright convective cloud (center of and right of center in 4) displays a plume which has been swept westward (to the left) by local currents in the planet's equatorial wind system.<p>Below and to the left and right of the Great Red Spot are a pair of white oval clouds; a third can be seen in 1. All three were formed almost 40 years ago and are the second oldest class of discrete features identified in the Jovian atmosphere.<p>Each of the pictures was produced from blue, green, and orange originals in JPL's Image Processing Laboratory.<br /><br /><a href="http://photojournal.jpl.nasa.gov/catalog/PIA00454" onclick="window.open(this.href); return false;" title="Voir l'image PIA00454: Early Voyager 1 Images of Jupiter sur le site de la NASA">Voir l'image PIA00454: Early Voyager 1 Images of Jupiter sur le site de la NASA.</a></div>

<h1>PIA00455: Jupiter with Io Crossing</h1><div class="PIA00455" lang="en" style="width:500px;text-align:left;margin:auto;background-color:#000;padding:10px;max-height:150px;overflow:auto;">Jupiter's satellite Io poses before the giant planet in this photo returned January 17, 1979, from a distance of 29 million miles (47 million kilometers). The satellite's shadow can be seen falling on the face of Jupiter at left. Io is traveling from left to right in its one-and-three-quarter-day orbit around Jupiter. Even from this great distance the image of Io shows dark poles and a bright equatorial region. Voyager will make its closest approach to Jupiter -- 174,000 miles (280,000 kilometer) -- on March 5. It will then continue to Saturn in November 1980, Meanwhile Voyager 2, a sister spacecraft, will fly past Jupiter July 9, 1979, and reach Saturn in August 1981. This color image was taken through orange, green and blue filters.

<h1>PIA00456: Jupiter's Great Red Spot and South Equatorial Belt</h1><div class="PIA00456" lang="en" style="width:800px;text-align:left;margin:auto;background-color:#000;padding:10px;max-height:150px;overflow:auto;">This Voyager 2 picture shows the Great Red Spot and the south equatorial belt extending into the equatorial region. At right is an interchange of material between the south equatorial belt and the equatorial zone. The clouds in the equatorial zone are more diffuse and do not display the structures seen in other locations. Considerable structure is evident within the Great Red Spot.

A high, white cloud is seen moving over the darker cloud, providing an indication of the structure of the cloud layers. Thin white clouds are also seen within the dark cloud.<p>At right, blue areas, free of high clouds, are seen.

<h1>PIA00490: Features of Jupiter's Great Red Spot</h1><div class="PIA00490" lang="en" style="width:800px;text-align:left;margin:auto;background-color:#000;padding:10px;max-height:150px;overflow:auto;"><p>This montage features activity in the turbulent region of Jupiter's Great Red Spot (GRS). Four sets of images of the GRS were taken through various filters of the Galileo imaging system over an 11.5 hour period on 26 June, 1996 Universal Time. The sequence was designed to reveal cloud motions. The top and bottom frames on the left are of the same area, northeast of the GRS, viewed through the methane (732 nm) filter but about 70 minutes apart. The top left and top middle frames are of the same area and at the same time, but the top middle frame is taken at a wavelength (886 nm) where methane absorbs more strongly. (Only high clouds can reflect sunlight in this wavelength.) Brightness differences are caused by the different depths of features in the two images. The bottom middle frame shows reflected light at a wavelength (757 nm) where there are essentially no absorbers in the Jovian atmosphere. The white spot is to the northwest of the GRS; its appearance at different wavelengths suggests that the brightest elements are 30 km higher than the surrounding clouds. The top and bottom frames on the right, taken nine hours apart and in the violet (415 nm) filter, show the time evolution of an atmospheric wave northeast of the GRS. Visible crests in the top right frame are much less apparent 9 hours later in the bottom right frame. The misalignment of the north-south wave crests with the observed northwestward local wind may indicate a shift in wind direction (wind shear) with height. The areas within the dark lines are "truth windows" or sections of the images which were transmitted to Earth using less data compression. Each of the six squares covers 4.8 degrees of latitude and longitude (about 6000 square kilometers). North is at the top of each frame.<p>Launched in October 1989, Galileo entered orbit around Jupiter on December 7, 1995. The spacecraft's mission is to conduct detailed studies of the giant planet, its largest moons and the Jovian magnetic environment.

<h1>PIA00548: False Color Mosaic of Jupiter's Belt-Zone Boundary</h1><div class="PIA00548" lang="en" style="width:625px;text-align:left;margin:auto;background-color:#000;padding:10px;max-height:150px;overflow:auto;">This false color mosaic shows a belt-zone boundary near Jupiter's equator. The images that make up the four quadrants of this mosaic were taken within a few minutes of each other. Light at each of Galileo's three near-infrared wavelengths is displayed here in the visible colors red, green and blue. Light at 886 nanometers, strongly absorbed by atmospheric methane and scattered from clouds high in the atmosphere, is shown in red. Light at 732 nanometers, moderately absorbed by atmospheric methane, is shown in green. Light at 757 nanometers, scattered mostly from Jupiter's lower visible cloud deck, is shown in blue. The lower cloud deck appears bluish white, while the higher layer appears pinkish. The holes in the upper layer and their relationships to features in the lower cloud deck can be studied in the lower half of the mosaic. Galileo is the first spacecraft to image different layers in Jupiter's atmosphere.<p>The edge of the planet runs along the right side of the mosaic. North is at the top. The mosaic covers latitudes -13 to +3 degrees and is centered at longitude 280 degrees west. The smallest resolved features are tens of kilometers in size. These images were taken on Nov. 5, 1996, at a range of 1.2 million kilometers by the solid state imaging (CCD) system aboard NASA's Galileo spacecraft.<p>Launched in October 1989, Galileo entered orbit around Jupiter on Dec. 7, 1995. The spacecraft's mission is to conduct detailed studies of the giant planet, its largest moons and the Jovian magnetic environment.
