Two volcanic plumes were discovered on an image of Io taken as part of the Voyager optical navigation effort. This is the first evidence of active volcanism on any body in the solar system other than Earth. 
Volcanic features of Io
Volcanic activity is apparently higher on Io than on any other body in the Solar System. Its volcanic landforms can be compared with features on Earth to indicate the type of volcanism present on Io.
Volcanic eruption plumes on Io
An umbrella-shaped plume detected above Io confirms that Io is volcanically active. Preliminary analyses of eight such eruptive plumes are presented.
Planetary science: Tidal flows in satellite oceans
Sub-surface oceans probably exist on several large satellites of Jupiter and Saturn. An analysis of Europa's tides suggests that some of the Rossby waves are resonantly enhanced by the obliquity,
Volcanic resurfacing rates and implications for volatiles on Io
Resurfacing rates and surface ages on Io are estimated, together with the material ejection and deposition rates of the active volcanic plumes.
Sulfur Volcanoes on Io
The ubiquity of sulfur on Io today demonstrates the importance of this element in the processes that formed its surface, and it is postulated that sulfur is the driving volatile for Ionian volcanism.
Advances in Planetary Geology
The surface of Mars displays a broad range of channel and valley features. There is as great a range in morphology as in scale. Some of the features of Martian geography are examined. Geomorphic
Dust Emission by Active Moons
In recent decades, volcanic and cryovolcanic activity on moons within the Solar System has been recognised as an important source of cosmic dust. Two moons, Jupiter’s satellite Io and Saturn’s
A comparison of volcanic eruption processes on Earth, Moon, Mars, Io and Venus
The silicate planets and satellites display a wide range of physical, chemical and atmospheric characteristics which may influence the nature of volcanism, a major geological process common to the
Volcanic Activity on Io During the Galileo Era
▪ Abstract Galileo's explorations have revealed a remarkable variety of eruptive styles among Io's diverse volcanoes. Activity at hundreds of volcanic centers ranges from dormant through sporadic to
