Io: A Volcanic Puzzle – NASA Solar System Exploration
WEBNov 9, 1995 — Since Jupiter is mainly liquid and gas, the warm interior can move upwards towards the surface without volcanic activity. On 7 December 1995, Galileo will have its one and only opportunity for a close encounter with Jupiter's moon Io, the most volcanically active body in the solar system.
Cassini Spots Potential Ice Volcano on Saturn Moon
WEBDec 13, 2010 — NASA's Cassini spacecraft has found possible ice volcanoes on Saturn's moon Titan that are similar in shape to those on Earth that spew molten rock.

Io Observer - NASA Solar System Exploration
WEBOct 1, 2024 — The Jovian moon Io is likely the most geologically active body in the solar system, offering insight into tidal heating, volcanic processes, and other phenomena. However, its location within Jupiter''s radiation belt presents significant engineering challenges that must be addressed to enable future missions to Io.
Callisto - NASA Solar System Exploration
WEBJun 26, 2019 — Italian astronomer Galileo Galilei discovered Callisto and Jupiter’s other three large moons: Ganymede, Io and Europa. The discovery led to the understanding that planets in our solar system orbit the Sun, instead of …
Cassini Finds an Atmosphere on Saturn's Moon Enceladus
WEBMar 15, 2005 — The Cassini spacecraft's two close flybys of Saturn's icy moon Enceladus have revealed that the moon has a significant atmosphere. Scientists, using Cassini's magnetometer instrument for their studies, say the source may be volcanism, geysers, or gases escaping from the surface or the interior.
10 Need-to-Know Things About Io - NASA Solar System Exploration
WEBThe moon Io is the most volcanically active world in the solar system. Io even has lakes of molten silicate lava on its surface.
Volcanoes and Auroras Glow in Eclipse Movie of Jupiter's Moon Io
WEBFeb 4, 2001 — The first movie ever made of Jupiter's moon Io while it is in eclipse shows bright spots of hot lava and changes in auroral glows. These images from NASA's Cassini spacecraft provide evidence that the auroras originate in electrical currents that connect Io and Jupiter along magnetic-field lines.
In Depth | Triton – NASA Solar System Exploration
WEBSpacecraft images show the moon has a sparsely cratered surface with smooth volcanic plains, mounds and round pits formed by icy lava flows. Triton consists of a crust of frozen nitrogen over an icy mantle believed to cover a core of rock and metal. Triton has a density about twice that of water.
