NASA's New Horizons snapped this view of Jupiter and its volcanic moon Io in early January 2007.
Io, the most volcanic body in the solar system, is seen in this composite image obtained by NASA's Galileo spacecraft in 1996. The smallest features that can be discerned are 2.5 kilometers in size.
Natural color image of Jupiter's moon Europa.
NASA's Cassini spacecraft captured this image on Dec. 7, 2000, just as two of Jupiter's four major moons, Europa and Callisto, were nearly perfectly aligned with each other and the center of the planet.
This photo, snapped by Hubble on April 9, 2007, shows Jupiter's moon Ganymede just before it ducks behind its giant host.
Voyager 1 took photos of Jupiter and two of its satellites (Io, left, and Europa). The new study says that moons orbiting a gas giant planet greater than 8 Jupiter masses could help astronomers detect a rogue planet.
Europa, a moon of Jupiter, appears as a thick crescent in this enhanced-color image from NASA's Galileo spacecraft, which has been orbiting Jupiter since 1995. The view combines images taken in violet, green and near-infrared filters in 1998 and 1995. The colors have been stretched to show the subtle differences in materials that cover the icy surface of Europa.
Images of Jupiter’s northern UV auroras were obtained using the Advanced Camera for Surveys onboard the Hubble Space Telescope in February 2007.
Skywatcher Jimmy Eubanks in Boiling Springs, South Carolina caught these photos of Jupiter and Uranus on Sept. 20, 2010 when Jupiter made its closest approach to Earth since 1963. Uranus [insert] was visible through telescopes near Jupiter.
An eclipse of the sun by Jupiter, as viewed from Galileo, reveals the rings. Small dust particles high in Jupiter's atmosphere, as well as the dust particles that compose the rings, can be seen by reflected sunlight.
A third red spot has appeared alongside the Great Red Spot and Red Spot Jr. in the turbulent Jovian atmosphere. The visible-light images were taken on May 9 and 10 with Hubble's Wide Field and Planetary Camera 2.
This is a mosaic of three New Horizons images of Jupiter's Little Red Spot, taken at 17:41 Universal Time on Feb. 26, 2007 from a range of 2.1 million miles (3.5 million kilometers). The image scale is 11 miles (17 kilometers ) per pixel, and the area covered measures 20,000 miles (33,000 kilometers) from top to bottom, two and one-half times the diameter of Earth.
Hubble Space Telescope ultraviolet image of the northern pole of Jupiter. Among many other auroral structures, the Io footprint is the most equator-ward feature close to the centre of the image. This spot is always located close to the feet of the magnetic field lines connected to the satellite Io.
X-ray auroras observed by the Chandra X-ray Observatory overlaid on a simultaneous optical image from the Hubble Space Telescope.
The surface of Europa. Sulfur-rich materials there are concentrated along geological features and may reflect the composition of the subsurface ocean. Image from the Solid-State Imaging instrument onboard Galileo.
Jupiter's high altitude clouds taken by the New Horizons Multispectral Visible Imaging Camera (MVIC), starting February 28, 2007, when the spacecraft was only 2.3 million kilometers (1.4 million miles) from the solar system's largest planet.
Europa, a moon among many circling Jupiter, appears to have a putative ocean hidden under its frozen surface crust. Tougher cameras, however, will be necessary to scope out the water regions beneath its shell of ice.
A composite image of Jupiter's moon Io. Volcanic plumes of gas spew sulfur dioxide hundreds of miles into space, as seen by the New Horizons spacecraft. Such activity accounts for a small chunk of the moon's immediate atmosphere, but eventually freezes and builds up a store of the material.
The icy moon Europa rises above Jupiter's cloud tops in this photo taken by New Horizons with its Long-Range Reconnaissance Imager (LORRI) on February 28, 2007, six hours after the spacecraft's closest approach to Jupiter.
This photo of Jupiter taken June 3, 2010 by Australian amateur astronomer Anthony Wesley shows a bright fireball from an apparent meteor or other object. Skywatcher Christopher Go of the Philippines also caught the event on video. Full Story.
Arc-shaped troughs (black and white arrows) extend 100s of kilometers on the surface of Jupiter's moon Europa. These enigmatic features are likely fractures resulting from a shift in Europa's spin axis. Vertical scale bar (right) is 100 km.
New thermal images from ESO’s Very Large Telescope (VLT) and other ground-based telescopes show swirls of warmer air and cooler regions never seen before within Jupiter’s Great Red Spot. The image on the left was obtained with the VISIR on the VLT in Chile on 18 May 2008. The image on the right was obtained by the NASA/ESA Hubble Space Telescope on 15 May 2008.
This image shows a comparison of Jupiter as seen in a visible light view taken by astronomer Anthony Wesley (left) and in infrared wavelengths used by NASA's SOFIA telescope during its "first light" flight on May 26, 2010. The infrared view was taken by the FORCAST camera on SOFIA. The white stripe in the infrared image is a region of relatively transparent clouds through which the warm interior of Jupiter can be seen. Full Story.
Detailed observations made by the Hubble Space Telescope have found that the flash of light seen June 3 on Jupiter came from a giant meteor burning up high above the planet's cloud tops. The space visitor did not plunge deep enough into the atmosphere to explode and leave behind any telltale cloud of debris, as seen in previous Jupiter collisions.
This Nov. 18 Gemini North Telescope image of Jupiter combines blue, red and yellow images into a false-color composite that clearly shows the storm in the South Equatorial Belt. The belt is now turning dark after a brief fade to white.
