Life on Ganymede
Where water exists on Earth we find life and the same could be said of Ganymede if the moon does indeed possess underground oceans. Proving this would be a very difficult task though as the layers of liquid would be very deep below the surface and covered with thick ice.
Origin of Name
Ganymede is named after a handsome mortal prince from Greek mythology who was abducted by Zeus to become cup-bearer to the gods.
