Jovian Moons [ID: 1]

There are at least 63 jovian moons! The largest four moons, Io, Europa, Ganymede and Callisto, are called the Galilean satellites because they were discovered by Galileo. We do not get close to them because Juno is in a polar orbit, but occasionally the spacecraft is close enough for images to be worthwhile. For example at PJ17 we imaged a volcanic plume erupting from Io!

    Regards earthlings!

    Have you heard about Mission Rahma? It's a department of the Galactic Federation that takes care of the cosmic plan for Earth and Humankind and it's based at a deep abyss in Ganimedes, which they call "Morlen". They are teaching a contact protocol so we can tune in with their frequency and start communicating with them.
