Io, with two plumes erupting from its surface, Galileo image, June 1997. 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]
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 ...
Tupan Patera is an active volcano on Jupiter's moon Io. It is located on Io's anti-Jupiter hemisphere at 18°44′S 141°08′W / 18.73°S 141.13°W / -18.73; -141. Tupan consists of a volcanic crater, known as a patera , 79 kilometers across and 900 meters deep. [ 2 ]
The level of activity seen is similar to a superfast spreading mid-ocean ridge on Earth. [4] It is the largest volcano on Io, producing about 10% of Io’s total thermal emission. [ 5 ] Temperature measurements of thermal emission at Loki Patera taken by Voyager 1 's Infrared Interferometer Spectrometer and Radiometer (IRIS) instrument were ...
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.
Tvashtar Paterae compose an active volcanic region of Jupiter's moon Io located near its north pole. It is a series of paterae, or volcanic craters. It is named after Tvashtar, the Hindu god of blacksmiths. [1] Tvashtar was discovered in IRTF images on November 26, 1999, several hours after a Galileo flyby.
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.
Galileo image of Thor taken in October 2001 [1]. Thor is an active volcano on Jupiter's moon Io.It is located on Io's anti-Jupiter hemisphere at A major eruption with high thermal emission and a large, volcanic plume was observed during a Galileo flyby on August 6, 2001, when the spacecraft flew through the outer portions of the plume allowing for direct sampling.
