At 3,270 miles across, Ganymede is 3/4 the size of Mars and the largest moon in the solar system.
(PacDis, Fall/’96, p.36)
1610 Jan 7, The astronomer Galileo Galilei sighted four of Jupiter's moons. Galileo discovered the 1st 3 Jupiter satellites, Io, Europa & Ganymede. He discovered mountains and valleys on the moon, that Jupiter has a moon of its own, and that the sun has spots which change. Galileo discovered multiple moons around Jupiter. He also observed Mars.
(V.D.-H.K.p.200)(SFC, 11/5/96, p.A4)(SFC, 11/29/96, p.A16)(AP, 1/7/98)(MC, 1/7/02)
1979 The spacecraft Voyager took pictures of Ganymede and Callisto.
(SFC, 7/11/96, p.C1)
1995 The space orbiter Galileo reached Jupiter and sent down a probe. Jupiter has 16 moons: 1) Callisto has ancient craters. 2) Europa has a smooth icy surface that may hide water. 3) Ganymede is grooved by huge parallel valleys 4) Io has erupting volcanoes.
(WSJ, 12/7/95, p.A-11A)
1996 Jun 26-27, The Galileo spacecraft took photographs of the Jupiter Moon. The surface showed broken crust and faulting. A possible magnetosphere, a region of hot ionized gases and highly charged particles, was detected. The camera focused on a ridge named Uruk Sulcus and another area called Galileo Regio from a distance of 524 miles.
(SFC, 7/11/96, p.C1)
1996 Dec 12, Scientists announced that Ganymede possesses a strong magnetic field due to a molten core. Its outer layer solid ice measured some 500 miles thickness.
(SFC, 12/12/96, p.A2)
1997 Oct 10, It was reported that Galileo detected complex organic molecules on Callisto and Ganymede.
(SFC, 10/10/97, p.A4)
1997 Dec 16, The Galileo spacecraft indicated a magnetic field around Ganymede. Metallic cores inside Io, Ganymede and Europa and the lack of a similar core inside Callisto was also indicated.
