Jupiter’s moon Ganymede is the largest satellite in the solar system. Larger than Mercury and Pluto, and only slightly smaller than Mars, it would easily be classified as a planet if were orbiting the sun rather than Jupiter. IN THIS IMAGE: To present the best information in a single view of Jupiter’s moon Ganymede, a global image mosaic was assembled, incorporating the best available imagery from NASA’s Voyager 1 and 2 spacecraft and NASA’s Galileo spacecraft. This image shows Ganymede centered at 200 west longitude. This mosaic (right) served as the base map for the geologic map of Ganymede (left). [Read the Full Story and video of the Ganymede map]

Ganymede’s interior, seen here, is composed of an iron core, rocky mantle, icy mantle, 100 kilometer deep liquid ocean and icy crust. Image released March 12, 2015.

Ganymede’s Auroral Belts

Ganymede’s auroras helped scientists see that the moon is likely harboring a vast, deep and salty liquid ocean below its surface. Image released March 12, 2015.

Ganymede might have a vast liquid ocean under its crusty outer shell, new data from the Hubble Space Telescope has shown. Image released March 12, 2015.

Ganymede Magnetic Field Rocking

This diagram examines the excursion of a pair of auroral belts on Jupiter’s moon Ganymede, providing insight into the moon’s interior. The rocking motion of the two aurorae indicates that that a large amount of saltwater exists beneath Ganymede’s crust. Image released March 12, 2015.

NASA’s Voyager 2 spacecraft snapped this color image of Jupiter’s moon Ganymede, the largest satellite in the solar system, on July 7, 1979 from a distance of 745,000 miles (1.2 million kilometers).

Jupiter’s Family Portrait

This “family portrait,” a composite of the Jovian system, includes the edge of Jupiter with its Great Red Spot, and Jupiter’s four largest moons, known as the Galilean satellites. From top to bottom, the moons shown are Io, Europa, Ganymede and Callisto.

Jupiter’s Moons in 1979: Ganymede by Voyager 2

Credit: UCL Faculty of Mathematical and Physical Sciences
This image shows Jupiter moon Ganymede taken by Voyager 2 in 1979. Voyager probes 1 and 2 visited the Jovian system in 1979, before taking different paths through the outer reaches of the Solar System, studying the giant planet as well as making numerous images of its moons. The relatively narrow field of view, combined with the Voyager probes’ close flybys meant that the photos had to be stitched together, which in the days before powerful computer graphics software meant printing them out and sticking them together by hand, like a giant jigsaw puzzle, interspersed with hand-written notes and computer printouts of technical information relating to the photographs.
