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]

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 majority currently not having an officially approved name.

May 16, 1994 · Several of the volcanoes periodically are active because Io is heated by tides raised by Jupiter's powerful gravity. The volcano Pele appears as a dark spot surrounded by an irregular orange oval in the lower part of the image.

Jun 23, 2022 · Volcanoes erupt almost daily on Io, and it is often said that the surface of Io changes as quickly as weather on Earth. Although that is somewhat of an exaggeration, Io does experience regular resurfacing due to the sheer number of active volcanoes across such a …

Mar 18, 2021 · A proposed mission called Io Volcano Observer (IVO) would visit Jupiter’s moon Io, which is a true volcanic wonderland with hundreds of erupting volcanoes gushing tons of molten lava and sulfurous gases at any moment.

Jan 29, 2025 · Jupiter’s moon Io is highly volcanically active, with around 400 volcanoes on its surface. On its most recent flyby of Io, NASA’s Juno spacecraft detected the most intense volcanic activity...

May 16, 1994 · One of Io's many volcanoes, Pele, appears as a dark spot surrounded by an irregular orange oval on the lower part of the moon. The orange material has been ejected from the volcano and spread over a huge area. Though the volcano was first discovered by the Voyager spacecraft, the distinctive orange color of the volcanic deposits is a new discovery.

Jan 28, 2025 · Scientists with NASA’s Juno mission have discovered a volcanic hot spot in the southern hemisphere of Jupiter’s moon Io. The hot spot is not only larger than Earth’s Lake …

Nov 20, 2023 · Glimpses from NASA’s Juno spacecraft have helped fill in views of Io’s volcanic hotspots, letting scientists gather clues.

Sep 25, 2020 · The most powerful volcanoes in the Solar System are not on Earth, but on Io, a tiny moon of Jupiter.
