During the G1 flyby in 1996, Galileo instruments detected Ganymede's magnetic field. [116] Data from the Galileo flybys was used to discover the sub-surface ocean, which was announced in 2001. [23] [40] High spatial resolution spectra of Ganymede taken by Galileo were used to identify several non-ice compounds on the surface. [52]
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 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 performed three additional flybys of Io, on August 6 and October 16, 2001 and January 17, 2002, during the Galileo Millennium Mission. Both encounters in 2001 allowed Galileo to observe Io's polar regions up-close, though imaging from the August 2001 flyby was lost due to a camera malfunction. [2]
Galileo observed the Loki volcano (largest in the Solar System) and a new eruption in the southern region of the moon. I33 102 (63) 17 January 2002 This was the closest of all the flybys of Io. The moon provided a gravity-assist necessary for Galileo ' s ultimate collision course with Jupiter.
The observatory is located off State Route 76 in northern San Diego County, California, two hours' drive from downtown San Diego and three hours' drive from central Los Angeles (UCLA, LAX airport). [38] Those staying at the nearby Palomar Campground can visit Palomar Observatory by hiking 2.2 miles (3.5 km) up Observatory Trail. [39]
Enki Catena (Enki from the Assyro-Babylonian principal water god of the Apsu, and catena from Latin meaning "chain") [1] is a crater chain on Ganymede measuring 161.3 kilometres (100.2 mi) long. This chain of 13 craters was probably formed by a comet which was pulled into pieces by Jupiter 's gravity as it passed too close to the planet. [ 2 ]
