Gliding past the planet Jupiter, the Cassini spacecraft captured this view of active Io, Jupiter's third largest moon, with the gas giant as a backdrop, in 2001.

NASA’s Juno spacecraft snapped a new view of Jupiter and its volcanic moon, Io, on July 30, revealing striking characteristics of the duo.

As of April 9, 2024, Juno completed its 60th close pass around Jupiter ('perijove'). Included in this was an additional encounter with Io, but at a distance of 16,500 kilometres.

Jupiter’s moon Io may have been volcanically active throughout its life. In this image of Io, taken by NASA’s Juno spacecraft in 2023, a bright volcanic plume can be seen on the left, just ...

The JunoCam instrument aboard our #JunoMission acquired six images of Jupiter's moon Io during its close encounter today. This black-and-white view was taken at an altitude of about 1,500 miles ...

The spacecraft will make its 57th and 58th closest approaches, or perijoves (close passes), of Jupiter on Dec. 30, 2023, and Feb. 3, 2024, when it will get within just 930 miles (1,500 km) of Io's ...

The tides that Jupiter raises on Io, however are powerful enough to induce sufficient friction in that moon's rocks, melting and volcanoes can result. A similar phenomenon produces ice volcanoes ...

Jupiter’s moon Io has likely been active for our solar system’s entire history The composition of Io's atmosphere indicates it has already lost sextillions of tons of sulfur, and will someday ...

The Io–Jupiter system is similar, in scale, to an exoplanet orbiting an M-dwarf, and if volcanic Io doesn't have a magma ocean then perhaps exoplanets on close orbits around M-dwarfs don't either.

It too plays host to subsurface oceans which could theoretically host life. Io’s volcanic eruptions can be huge in scale, as seen by Galileo in 1997. Io, in comparison, is a hot and volcanic place.
