Jupiter's Moon Io Has Splendid Dunes

Scientists have long wondered how Jupiter's innermost moon, Io, has meandering ridges as grand as any that can be seen in movies like "Dune." Now, a Rutgers research study has provided a new explanation of how dunes can form even on a surface as icy and roiling as Io's.

Unraveling the geological processes ongoing at Io's numerous sites of active volcanism requires high spatial resolution to, for example, measure the areal coverage of lava flows or identify the presence of multiple emitting regions within a single volcanic center.

The atmosphere on Jupiter's moon Io is a witches' brew, composed primarily of the sulfurous exhalations of more than 400 volcanoes that dot the surface.

Io Casts A Shadow On Jupiter

Jupiter's volcanically active moon Io casts its shadow on the planet in this dramatic image from NASA's Juno spacecraft.

A large volcanic event was detected on Jupiter's moon Io using Jovian sodium nebula brightness variation, a new paper in Astrophysical Journal Letters said.

Data collected by NASA's Juno spacecraft using its Jovian InfraRed Auroral Mapper (JIRAM) instrument point to a new heat source close to the south pole of Io that could indicate a previously undiscovered volcano on the small moon of Jupiter.

Taking advantage of a rare orbital alignment between two of Jupiter's moons, Io and Europa, researchers have obtained an exceptionally detailed map of the largest lava lake on Io, the most volcanically active body in the solar system.

Tracking of Eruptions on Io

Jupiter's moon Io continues to be the most volcanically active body in the solar system, as documented by the longest series of frequent, high-resolution observations of the moon's thermal emission ever obtained.

A Southwest Research Institute-led team has documented atmospheric changes on Io, Jupiter's volcanically active satellite, as the giant planet casts its shadow over the moon's surface during daily eclipses.

Tides flowing in a subsurface ocean of molten rock, or magma, could explain why Jupiter's moon Io appears to have its volcanoes in the "wrong" place.

With the first detailed observations of a lava lake on a moon of Jupiter, the Large Binocular Telescope Observatory in Arizona places itself as the forerunner of the next generation of Extremely Large Telescopes.

Massive Eruptions on Io

Three massive volcanic eruptions occurred on Jupiter's moon Io within a two-week period last August, leading astronomers to speculate that these presumed rare "outbursts".

Antares Rocket Preparation

An Orbital Sciences Corporation Antares rocket is seen on launch Pad-0A at NASA's Wallops Flight Facility, Monday, January 6, 2014 in advance of a planned Wednesday, Jan. 8th, 1:32 p.m. EST launch, Wallops Island, VA.

NASA and Orbital Sciences Corp. Saturday moved the targeted launch date of the Orbital-1 resupply mission to the International Space Station.

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.

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.

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.
