Four of the jovian satellites are observed here: Ganymede, Europa, Io and Callisto. Europe is the front of the planet, and Ganymede is furthest from Jupiter as seen in the last pictures.
They are also Galilean satellites.
Jupiter stunned by the beauty many astronomers since the invention of the telescope. They did not have our present technology to photograph or film it, and therefore they draw most of what they observed.
The first person who observed Jupiter was Galileo Galilei on January 7 1610. However, his telescope was too small to detect features on the planet, but could see the four largest moons, now called Galilean moons, precisely this is why. Observations of these satellites orbiting Jupiter was what convinced Galileo that the Earth is not in the center of the Universe.
