Herschel Links Jupiter's Water to Comet Impact

Water detected by Herschel
ESA's Herschel space observatory has solved a long-standing mystery as to the origin of water in the upper atmosphere of Jupiter, finding conclusive evidence that it was delivered by the dramatic impact of comet Shoemaker-Levy 9 in July 1994.

Are Io's Volcanoes In The Wrong Locations?

Ra-Patera Volcano on Io
Jupiter's moon Io is the most volcanically active world in the solar system, with hundreds of volcanoes, some erupting lava fountains up to 250 miles high (about 400 kilometers). However, concentrations of volcanic activity are significantly displaced from where they are expected to be, based on models that predict how the moon's interior is heated, according to NASA and European Space Agency researchers.
'Hot spots' ride a merry-go-round on Jupiter 
The dark hot spot in this false-color image from NASA's Cassini spacecraft is a window deep into Jupiter's atmosphere. All around it are layers of higher clouds, with colors indicating which layer of the atmosphere the clouds are in.
ESA Selects Science Instrument and Hardware for European Mission to Jupiter
The JUpiter ICy moons Explorer mission, JUICE, will carry a total of 11 scientific experiments to study the gas giant planet and its large ocean-bearing moons, ESA announced today.
NASA Selects Science Instrument and Hardware for European Mission to Jupiter
NASA has selected key contributions to a 2022 European Space Agency (ESA) mission that will study Jupiter and three of its largest moons in unprecedented detail. The moons are thought to harbor vast water oceans beneath their icy surfaces.
Io's Volcanism Controls Jupiter's Magnetospheric Activity
Jupiter's volcanic moon Io spews out volcanic gas, which reaches its atmosphere and becomes ionized, forming what is known as the Io plasma torus. This plasma torus can interact with Jupiter's magnetosphere, possibly affecting auroral activity there.
Jupiter - Turmoil from Below, Battering from Above
Jupiter, the mythical god of sky and thunder, would certainly be pleased at all the changes afoot at his namesake planet. As the planet gets peppered continually with small space rocks, wide belts of the atmosphere are changing color, hotspots are vanishing and reappearing, and clouds are gathering over one part of Jupiter, while dissipating over another.
Io's Insane Volcanic Activity
Watching active volcanic eruptions should definitely be done from a distance, but a group of California researchers has figured out how to do it from the comfort of home. Using an ingenious combination of Earth-based telescopic surveys and archival data, they have gathered nearly 40 distinct snapshots of effusive volcanic eruptions and high temperature outbursts on Jupiter's tiny moon, Io, showing details as small as 100 km (60 miles) on the moon's surface.
NASA's WISE Colors in Unknowns on Jupiter Asteroids
Scientists using data from NASA's Wide-field Infrared Survey Explorer, or WISE, have uncovered new clues in the ongoing mystery of the Jovian Trojans -- asteroids that orbit the Sun on the same path as Jupiter. Like racehorses, the asteroids travel in packs, with one group leading the way in front of the gas giant, and a second group trailing behind.
Amateur Astronomer Photographs the Surface of Ganymede
Technology has radically changed the contributions that amateurs can make to the field of astronomy. Using a readily-available 'hobby' telescope, off-the-shelf camera and computer equipment, plus experienced observing skills, Emmanuel I. Kardasis of the Hellenic Amateur Astronomy Association has produced the first amateur albedo map of Jupiter's moon Ganymede.
Liquid Water Near Europa's Surface a Rarity
Europa, the enigmatic moon of Jupiter, is believed to be home to a subsurface ocean of liquid water. However, future missions to explore Europa's ocean may need to dig deep.
Juno's Two Deep Space Maneuvers are 'Back-To-Back Home Runs'
NASA's Juno spacecraft successfully executed a second Deep Space Maneuver, called DSM-2 last Friday, Sept. 14. The 30 minute firing of its main engine refined the Jupiter-bound spacecraft's trajectory, setting the stage for a gravity assist from a flyby of Earth on Oct 9, 2013. Juno will arrive at Jupiter on July 4, 2016.
To Planets and Beyond: Voyager Celebrates 35 Years
WHAT: NASA's Jet Propulsion Laboratory in Pasadena, Calif., celebrates the 35th anniversary of the Voyager mission, whose twin spacecraft conducted a Grand Tour of the planets and are now headed into interstellar space.
JUICE Mission to Jupiter
Jupiter's icy moons are the focus of Europe's next large science mission, ESA announced today. The Jupiter Icy moons Explorer - JUICE - was selected over two other candidates: NGO, the New Gravitational wave Observatory, to hunt for gravitational waves, and ATHENA, the Advanced Telescope for High-Energy Astrophysics.
Jupiter Moon's Subsurface Ocean of Water
Data from a previous NASA planetary mission, Galileo, have provided scientists evidence of what appears to be a body of liquid water just beneath the icy surface of Jupiter's moon, Europa. The data suggest that, not only is the volume of this Europan subsurface ocean similar to that of the North American Great Lakes, but also that there is significant exchange between the moon's icy shell and the ocean beneath.
NASA's Juno to Sharpen Understanding of Jupiter's Origins
Scientists explain what they hope to learn from the Juno mission to Jupiter that's set to launch August 5 at 11:34 a.m. EDT from Cape Canaveral, Florida.
ScienceCasts: What Lies Inside Jupiter
For four long centuries the gas giant's vast interior has remained hidden from view. NASA's Juno probe, scheduled to launch on August 5th, could change all that.
