This page showcases our resources for those interested in learning more about Jupiter. Jupiter Resources. Io has hundreds of visible volcanic vents, some of which blast jets of frozen vapor and "volcanic snow" hundreds of miles high into its atmosphere.
These gases could be the sole product of these eruptions, or there could be some associated silicate rock or molten sulfur present. The areas around these vents show evidence that they have been "resurfaced" with a flat layer of new material.
These resurfaced areas are the dominant surface feature of Io. The very small number of impact craters on these surfaces, compared to other bodies in the solar system, is evidence of Io's continuous volcanic activity and resurfacing. This eruption is thought to have launched hot lava hundreds of miles above Io's surface. More information.
During that two-week period, eruptions powerful enough to launch material hundreds of miles above the surface of the moon are believed to have occurred. Other than Earth, Io is the only body in the solar system that is capable of erupting extremely hot lava. Because of the moon's low gravity and the magma's explosivity , large eruptions are believed to launch tens of cubic miles of lava high above the moon and resurface large areas over a period of just a few days.
The accompanying infrared image shows the August 29, eruption and was acquired by Katherine de Kleer of the University of California at Berkeley using the Gemini North Telescope, with support from the National Science Foundation. It is one of the most spectacular images of volcanic activity ever taken. At the time of this image, large fissures in Io's surface are believed to have been erupting "curtains of fire" up to several miles long.
These "curtains" are probably similar to the fountaining fissures seen during the eruption of Kilauea in Hawaii. Cryovolcano mechanics: Diagram of how a cryovolcano might work on Io or Enceladus.
Pockets of pressurized water a short distance below the surface are heated by internal tidal action. When pressures become high enough, they vent to the surface. Triton, a moon of Neptune, was the first location in the solar system where cryovolcanoes were observed.
The Voyager 2 probe observed plumes of nitrogen gas and dust up to five miles high during its flyby. These eruptions are responsible for Triton's smooth surface because the gases condense and fall back to the surface, forming a thick blanket similar to snow. Some researchers believe that solar radiation penetrates the surface ice of Triton and heats a dark layer below. The entrapped heat vaporizes subsurface nitrogen, which expands and eventually erupts through the ice layer above.
This would be the only known location of energy from outside of a body causing a volcanic eruption - the energy usually comes from within. Cryovolcano on Enceladus: An artist's vision of what a cryovolcano might look like on the surface of Enceladus, with Saturn visible in the background. Cryovolcanoes on Enceladus, a moon of Saturn, were first documented by the Cassini spacecraft in The spacecraft imaged jets of icy particles venting from the south polar region.
This made Enceladus the fourth body in the solar system with confirmed volcanic activity. Researchers used ALMA to capture images of the moon as it moved into and out of Jupiter's shadow to understand more about the moon's atmosphere. Venus isn't habitable -- and it could be all Jupiter's fault. During that time we can only see volcanically-sourced sulfur dioxide. We can therefore see exactly how much of the atmosphere is impacted by volcanic activity," said Statia Luszcz-Cook, study coauthor and observational astrophysicist at Columbia University, in a statement.
The scientists also saw potassium chloride gas, a common component of magma, emerging from the volcanoes. The researchers believe that this suggests that the magma reservoirs differ between volcanoes. Hubble spies stormy weather on Jupiter. Io is only slightly larger than our moon, but it couldn't be more different. What's more, its environment is unlike anything found on Earth.
The moon, named for a mortal woman who is transformed into a cow during a fight between Zeus and Hera in Greek mythology, has lava fountains that can erupt to reach dozens of miles high. Go Further.
