What did Galileo discover about the moons of Ganymede and Callisto?
Galileo magnetic data provide evidence that the moons Ganymede and Callisto also likely have a liquid saltwater layer. Galileo discovered the first moon around an asteroid—tiny Dactyl orbits the asteroid Ida. Ganymede is the first moon known to possess a magnetic field.
When was Ganymede discovered and by whom?
Discovery. Ganymede was discovered by Galileo Galilei on Jan. 7, 1610. The discovery, along with three other Jovian moons, was the first time a moon was discovered orbiting a planet other than Earth. The discovery of the four Galilean satellites eventually led to the understanding that planets in our solar system orbit the sun,…
What is special about the moon Ganymede?
Ganymede is the largest moon in our solar system and the only moon with its own magnetic field. The magnetic field causes auroras, which are ribbons of glowing, electrified gas, in regions circling the moon’s north and south poles.
Where is Ganymede’s magnetic field located on Jupiter?
Ganymede’s magnetic field is embedded inside Jupiter’s massive magnetosphere. A 3D model of Jupiter’s moon Ganymede, the largest moon in the solar system. Credit: NASA Visualization Technology Applications and Development (VTAD) › Download Options
