Jupiter moon Io volcanic activity (left: December 14, 2022; right: March 1, 2023) This is a list of named volcanic surface features on Jupiter's moon Io. These names have been approved for use by the International Astronomical Union. The features listed below represent a subset of the total known volcanic features on Io's surface with the ...
Volcanism on Io, a moon of Jupiter, is represented by the presence of volcanoes, volcanic pits and lava flows on the surface. Io's volcanic activity was discovered in 1979 by Linda Morabito, an imaging scientist working on Voyager 1. [1] Observations of Io by passing spacecraft and Earth-based astronomers have revealed more than 150 active ...
On Io, catenae / k ə ˈ t iː n ə / (crater chains, sg. catena) are named after sun gods in various mythologies. In 2006, the use of the term catena was discontinued in favor of the patera / ˈ p æ t ə r ə / (plural paterae / ˈ p æ t ə r iː /). Below is a list of features that previously used the descriptor term catena.
Rare cases of volcanic mountains, such as the shield volcano Tsũi Goab Tholus, use the term tholus (plural: tholi). Ionian tholi are named after people associated with the Io myth or nearby features on Io's surface. [5] See also the list of volcanic features on Io and the list of regions on Io.
Io (/ ˈ aɪ. oʊ /), or Jupiter I, is the innermost and second-smallest of the four Galilean moons of the planet Jupiter.Slightly larger than Earth's moon, Io is the fourth-largest moon in the Solar System, has the highest density of any moon, the strongest surface gravity of any moon, and the lowest amount of water by atomic ratio of any known astronomical object in the Solar System.
There's a moon teeming with lava-spewing volcanoes in our solar system, and a NASA spacecraft is getting closer to this intense world. The pioneering Juno spacecraft, which arrived at Jupiter in ...
The largest volcanic structure here is the Chaac Patera (105 km X 48 km). The paterae found in the Chaac-Camaxtli region are Chaac, Balder Patera, Grannos, Ababinili, Ruaumoko, Steropes, Camaxtli, Tien Mu, Utu, and Mentu. [1] This region is full of features that provide clues to the volcanism, tectonism, and magmatic processes on Io.
The thrust faulting and uplifting of large crust blocks on Io are interpreted by a model proposed by Schenk and Bulmer's 1998 paper. [3] In the model, Io's crust keeps recycling. Violent volcanic activity brings lava to the surface and older, buried layers are forced to subside. The old volcanic crust materials are compressed laterally as they ...
