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 ...
Ganymede: Jupiter III Galileo [9] [10] discovered the Galilean moons. These satellites were the first celestial objects that were confirmed to orbit an object other than the Sun or Earth. Galileo saw Io and Europa as a single point of light on 7 January 1610; they were seen as separate bodies the following night. [11] Callisto: Jupiter IV o: 8 ...
Ganymede is the only satellite in the Solar System known to possess a magnetosphere, likely created through convection within the liquid iron core. The satellite has a thin oxygen atmosphere that includes O, O 2, and possibly O 3. Ganymede's discovery is credited to Galileo Galilei, who observed it in 1610.
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 ...
