PIX4624055 Neptune from Triton - Illustration - Neptune from the surface of Triton - Neptune seen from the icy surface of his Triton satellite. White cirrus clouds race across a crescent Neptune as it presides over Triton's bleak and frozen south polar region. Sheets of frozen nitrogen ice with traces of other substances, including frozen methane and carbon monoxide, overlie Triton's darker material. The ice has turned pink due to the interaction with ultraviolet light from the distant Sun. Further south all of the surface of Triton is covered by such ices

A full Neptune washes Triton's frozen surface with an indigo light, the only source of illumination on this now Triton's dark side. Fortuitous alignment of the Sun, Triton and Neptune causes this satellite's shadow to fall on Neptune's distant cloud tops 220 thousand miles away. This view is from within a deep, crater - like depression on Triton's northern hemisphere

PIX4624042 Neptune - Illustration - Neptune's Great Dark Spot - Illustration - Artist's view of Neptune with its ring system and large dark spot observed by the Voyager 2 probe in 1989. This is how Neptune's Great Dark Spot and rings may have looked in 1989 from a position just beneath Neptune's ring plane. The outermost Adams ring is near the top of the frame, and beneath that is the much broader and diffuse Lassell ring. Further in toward Neptune and abutting the Lassell ring is the thin Le Verrier ring, and beyond that is the diffuse Galle ring. The Great Dark Spot is believed to be a storm similar to, but only half the size of, Jupiter's Great Red Spot. While Jupiter's Great Red Spot has been raging for at least 400 years, subsequent observations of Neptune's Great Dark Spot in 1994 by the Hubble Space Telescope revealed that this storm has since disappeared. The Great Dark Spot was a very dynamic weather system, generating massive, white clouds similar to high - altitude cirrus clouds on Earth. Unlike cirrus clouds on Earth however, which are composed of crystals of water ice, Neptune's cirrus clouds are made up of crystals of frozen methane. Neptune's clouds are driven by winds of 1,200 mph, the fastest winds of any planet in the Solar System

PIX4624079 Neptune - Illustration - Artist's view of Neptune with its ring system and large dark spot observed by the Voyager 2 probe in 1989. This image suggests how Neptune might look from a position in space above the plane of its rings. Like Uranus, Neptune is a Gas Giant, composed primarily of hydrogen and helium gases surrounding a relatively small, dense core of molten rock and metal. Also like Uranus, Neptune has charcoal - colored rings, although they appear to be fewer in number than Uranus's. While Neptune's diameter is slightly less than Uranus ', it has more mass. Neptune's blue color is due to the presence of methane in its upper atmosphere. The dark spot in the southern hemisphere beneath the rings, dubbed “” The Great Dark Spot,””” is believed to be a giant storm which was active in 1989 when Voyager 2 photographed Neptune. Just beyond the rings at Neptune's 7 o'clock position, barely discernable from the background stars, is the tiny satellite Proteus. With an average diameter of 260 miles, Proteus is the second - largest of Neptune's eight known satellites (a distant second compared to Neptune's largest satellite Triton which has a diameter of 1,677 miles)

PIX4622808 Neptune - Voyager 2 - Image of the Great Dark Spot on Neptune obtained by the Voyager 2 probe on August 23, 1989. The Great Dark Spot is the size of the Earth and winds are blowing at 300 m/s. This spot has now disappeared but other dark spots have been detected since then. Date: 08/23/89 Range: 2.8 million km. (1.7 million miles) Smallest Resolvable Feature: 50 km or 31 miles This Voyager 2 image shows the last face on view of the Great Dark Spot that Voyager 2 will take with the narrow angle camera. It was made 45 hours before the closest approach to Neptune. the image shows feathery white clouds that overlie the boundary of the dark and light blue regions. the pinwheel (spiral) structure of both the dark boundary and the white cirrus suggest a storm system rotating counterclockwise. Periodic, small - scale patterns in the white clouds, possibly waves, are short - lived and do not persist from one Neptunian rotation to the next.

PIX4622776 Neptune - Voyager 2 - Image of Neptune obtained by the Voyager 2 probe on August 14, 1989 at 14.8 million km from the planet. Neptune has an equatorial diameter of about 49,000 kilometres. Its blue color is due to the abundance of methane in its atmosphere. On this photo, on the right, the Great Dark Spot, which is the size of the Earth where winds are blowing at 300 m/s. This spot has now disappeared but other dark spots have been detected since then. 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 picture shows 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

PIX4622787 Neptune - Voyager 2 - Neptune has an equatorial diameter of about 49,000 kilometres. Its blue color is due to the abundance of methane in its atmosphere. On this photo, on the left, the Great Dark Spot, which is the size of the Earth where winds are blowing at 300 m/s. This spot has now disappeared but other dark spots have been detected since then. Image of Neptune obtained by the Voyager 2 probe on August 16, 1989. During August 16 and 17, 1989, the Voyager 2 narrow - angle camera was used to photograph Neptune almost continuously, recording approximately two and one - half rotations of the planet. These images represent the most complete set of full disk Neptune images that the spacecraft will acquire. This picture from the sequence shows two of the four cloud features which have been tracked by the Voyager cameras during the past two months. The large dark oval near the western limb (the left edge) is at a latitude of 22 degrees south and circuits Neptune every 18.3 hours. The bright clouds immediately to the south and east of this oval are seen to substantially change their appearances in periods as short as four hours. The second dark spot, at 54 degrees south latitude near the terminator (lower right edge), Neptune circuits every 16.1 hours. This image has been processed to enchance the visibility of small features, at some sacrifice of color fidelity

Eris was discovered in 2003 and is now the largest of the known dwarf planets. It is believed to be slightly more massive than Pluto and follows a highly eccentric orbit that alternately brings it as close as the orbits of Neptune and Pluto and as far as over twice Pluto's furthest distance from the Sun. It was the discovery of Eris that prompted the re-evaluation of Pluto as a planet

A comet, the asteroid belt and Pluto's orbit are also represented. Our solar system features eight planets, seen in this artist's diagram. Although there is some debate within the science community as to whether Pluto should be classified as a Planet or a dwarf planet, the International Astronomical Union has decided on the term plutoid as a name for dwarf planets like Pluto. This representation is intentionally fanciful, as the planets are depicted far closer together than they really are. Similarly, the bodies' relative sizes are inaccurate. This is done for the purpose of being able to depict the solar system and still represent the bodies with some detail. (Otherwise the Sun would be a mere speck, and the planets -even the majestic Jupiter - would be far too small to be seen.

PIX4573100 Planet around the star Fomalhaut - Planet orbiting star Fomalhaut - First visible light photo of an extrasolar planet obtained by the space telescope Hubble. The planet called Fomalhaut b, is a planet with a mass close to Jupiter, orbiting the star Fomalhaut, 25 years - light from Earth in the constellation of Southern Fish. The star Fomalhaut (indicated by a white dot) is hidden here to show the dust disc surrounding it and the position of the planet. Located at a distance of about four times that separating Neptune from the Sun, Fomalhaut b makes a complete orbit around its star in 872 years. November 2008 - This image, taken with the Advanced Camera for Surveys aboard the NASA/ESA Hubble Space Telescope, shows the newly discovered planet, Fomalhaut b, orbiting its parent star, Fomalhaut. The small white box at lower right pinpoints the planet's location. Fomalhaut b has carved a path along the inner edge of a vast, dusty debris ring encircling Fomalhaut that is 34.5 billion kilometers across. Fomalhaut b lies three billion kilometers inside the ring's inner edge and orbits 17 billion kilometers from its star. The inset at bottom right is a composite image showing the planet's position during Hubble observations taken in 2004 and 2006. Astronomers have calculated that Fomalhaut b completes an orbit around its parent star every 872 years. The white dot in the centre of the image marks the star's location. The region around Fomalhaut's location is black because astronomers used the Advanced Camera's coronagraph to block out the star's bright glare so that the dim planet could be seen. Fomalhaut b is 100 million times fainter than its star. The radial streaks are scattered starlight. The red dot at lower left is a background star. The Fomalhaut system is 25 light - years away in the constellation Piscis Austrinus. This false - colour image was taken in October 2004 and July 2006

In the sky, the planet Saturn and its satellite Mimas. Liquid water reaches the surface of Enceladus' south pole and drives a massive plume of ice crystals into the sky. The combination of Enceladus' low surface gravity and the geyser's force accelerate the crystals to escape velocity, where sunlight breaks the water molecules down into their constituent atoms of hydrogen and oxygen. Saturn itself appears low on the horizon due to the proximity to Enceladus' pole. The small object immediately to Saturn's left is another icy moon named Mimas. Somewhat smaller than Enceladus and closer to Saturn, Mimas sprints around Saturn in slightly less than one Earth day. In March 2006 Nasa's Cassini probe revealed evidence of water - driven geysers on the surface of Enceladus. At first glance Enceladus doesn't seem to be a likely host for liquid water as the surface is extremely cold, about - 330* F. However, tidal forces from Saturn's massive gravity alternately pull and push on Enceladus 'interior, creating enough heat to melt the water ice immediately beneath the surface. This water is believed to periodically break through the surface as geysers, similar to Yellowstone's Old Faithful. There are only three other places in the Solar System where this kind of geologic activity is known to exist: our own Earth, Jupiter's satellite Io, and Neptune's satellite Triton. What makes Enceladus especially interesting is that this the most compelling evidence yet for liquid water - - a requirement for life - - on any world beyond the Earth

PIX4633164 Earth at the end of Permian - Ring arcs over the Permian Earth - A ring of rocks and dust is orbiting the Earth. The massive continent below is Pangee and the ocean to the west is Panthalassa. This is what Earth was supposed to look like at the end of Permian, about 260 million years ago, before the first dinosaurs appeared. This ring around the Earth was of earthly origin, constitutes debris thrown into orbit by collision with a meteorite or comet. Over time, these debris have either fallen or fallen back to Earth in a meteorite rain. A dusty ring arc orbits four thousand miles above Earth's equator. The massive continent below is Pangea and the ocean to the west is Panthalassa. This is how the Earth may have appeared during the end of the Permian period, a time just prior to the appearance of the dinosaurs, when continental drift was pulling Pangea apart into the seven continents we know today. 260 million years ago the Earth may have been host to ring arcs similar to the incomplete rings that currently circumscribe the planet Neptune. Unlike Neptune's rings, the ring arcs around the Earth were of terrestrial origin, debris thrown into orbit by a collision with a large meteorite or comet. The debris consisted of tiny pebbles that were once molten droplets of ejecta, long since cooled in the vacuum of space. The orbit of the ring arc would eventually decay, returning the debris back to Earth as a shower of meteorites. This debris is found on Earth's surface today in the form of dark, glassy objects known as tektites

November 2008 - This image, taken with the Advanced Camera for Surveys aboard the NASA/ESA Hubble Space Telescope, shows the newly discovered planet, Fomalhaut b, orbiting its parent star, Fomalhaut. The small white box at lower right pinpoints the planet's location. Fomalhaut b has carved a path along the inner edge of a vast, dusty debris ring encircling Fomalhaut that is 34.5 billion kilometers across. Fomalhaut b lies three billion kilometers inside the ring's inner edge and orbits 17 billion kilometers from its star. The inset at bottom right is a composite image showing the planet's position during Hubble observations taken in 2004 and 2006. Astronomers have calculated that Fomalhaut b completes an orbit around its parent star every 872 years. The white dot in the centre of the image marks the star's location. The region around Fomalhaut's location is black because astronomers used the Advanced Camera's coronagraph to block out the star's bright glare so that the dim planet could be seen. Fomalhaut b is 100 million times fainter than its star. The radial streaks are scattered starlight. The red dot at lower left is a background star. The Fomalhaut system is 25 light - years away in the constellation Piscis Austrinus. This false - colour image was taken in October 2004 and July 2006

PIX4624480 Summer on Pluto - Illustration - Summer on Pluto - Artist view - Artist view of Pluto's surface when the planet is closer to the Sun and sees its weak atmosphere reforming. Despite its small size and extreme distance from the Sun, Pluto does have an atmosphere. The atmosphere arises because there are periods when Pluto is closer to the Sun than Neptune, making it the 8th planet from the Sun for roughly 20 years at a time (on 11 February 1999, Pluto crossed Neptune's orbit and once again became farther from the Sun Neptune and will remain so until the year 2231). During this plutonian “” summer”” the ices on Pluto's surface sublimate and form a methane and nitrogen atmosphere. This atmosphere is continually produced and lost again while Pluto is inside Neptune's orbit; during this time the density of Pluto's atmosphere may rival that of Mars

PIX4669572 A ring of rocks and dust is orbiting the Earth. The massive continent below is Pangee and the ocean to the west is Panthalassa. This is what Earth was supposed to look like at the end of Permian, about 260 million years ago, before the first dinosaurs appeared. This ring around the Earth was of earthly origin, constitutes debris thrown into orbit by collision with a meteorite or comet. Over time, these debris have fallen or fallen to Earth in a meteorite rain - A dusty ring arc orbits four thousand miles above Earth's equator. The massive continent below is Pangea and the ocean to the west is Panthalassa. This is how the Earth may have appeared during the end of the Permian period, a time just prior to the appearance of the dinosaurs, when continental drift was pulling Pangea apart into the seven continents we know today - 260 million years ago the Earth may have been host to ring arcs similar to the incomplete rings that currently circumscribe the planet Neptune . Unlike Neptune's rings, the ring arcs around the Earth were of terrestrial origin, debris thrown into orbit by a collision with a large meteorite or comet. The debris consisted of tiny pebbles that were once molten droplets of ejecta, long since cooled in the vacuum of space. The orbit of the ring arc would eventually decay, returning the debris back to Earth as a shower of meteorites. This debris is found on Earth's surface today in the form of dark, glassy objects known as tektites.: La Terre à la fin du Permien - Ring arcs over the Permian Earth

UIS5100618 Neptune, full disc view, 2 April 1990. 'This picture of Neptune was produced from the last whole planet images taken through the green and orange filters on the Voyager 2 narrow angle camera. The images were taken at a range of 4.4 million miles from the planet, 4 days and 20 hours before closest approach. The picture shows the Great Dark Spot and its companion bright smudge; on the west limb the fast moving bright feature called Scooter and the little dark spot are visible. These clouds were seen to persist for as long as Voyager's cameras could resolve them. North of these, a bright cloud band similar to the south polar streak may be seen. Years later, when the Hubble telescope was focused on the planet, these atmospheric features had changed, indicating that Neptune's atmosphere is dynamic.' ©SSPL/NASA

This picture taken by Voyager 2 from a distance of 21 million kilometres, shows the planet and three of its moons; Tethys, Dione and Rhea, with one casting a shadow on the planet. Saturn is a gas giant similar in atmospheric composition to Jupiter, with banded cloud formations. It rotates very quickly, causing it to appear oblate (flattened at the poles). The origin and formation of the rings, which are composed of ice and ice-coated dust and rock, are not precisely understood, but it seems that tidal effects caused by some of Saturn's moons play a role in maintaining their structure. NASA's two Voyager spacecraft were launched in 1977 to explore the planets in the outer solar system. Voyager 2 passed Saturn in August 1981, before continuing on to Uranus and Neptune. ©SSPL/NASA
