The Galilean moons are named after Galileo Galilei, who observed them in either December 1609 or January 1610, and recognized them as satellites of Jupiter in March 1610; [2] they remained the only known moons of Jupiter until the discovery of the fifth largest moon of Jupiter Amalthea in 1892. [3]
The existence of a liquid, iron–nickel-rich core [71] provides a natural explanation for the intrinsic magnetic field of Ganymede detected by Galileo spacecraft. [82] The convection in the liquid iron, which has high electrical conductivity, is the most reasonable model of magnetic field generation. [23]
The internal structure of Ganymede. Galileo returned to Ganymede on orbits G7 and G9 in April and May 1997, and on G28 and G29 in May and December 2000 on the GMM. [217] Images of the surface revealed two types of terrain: highly cratered dark regions and grooved terrain sulcus. Images of the Arbela Sulcus taken on G28 made Ganymede look more ...

Galileo Regio is a large, dark surface feature on Jupiter's moon Ganymede. [1] It is a region of ancient dark material that has been broken apart by tectonism and is now surrounded by younger, brighter material (such as that of Uruk Sulcus) that has been upwelling from Ganymede's interior. It is thought to be some 4 billion years old and is ...
The model kit was first announced late last year, but details were sparse up until now. Now we have a release date – September 2024 – and a price. The kit will set prospective buyers back 3850 ...
The distinction between a satellite and a classical planet was not recognized until after the heliocentric model of the Solar System was established. When in 1610 Galileo discovered the first satellites of another planet (the four Galilean moons of Jupiter), he referred to them as "four planets flying around the star of Jupiter at unequal intervals and periods with wonderful swiftness."
