Everything You'll Have Covered

What are the Galilean Moons?

~ The Galilean Moons are the four major moons of Jupiter. They include Io, Europa, Ganymede, and Callisto. They are called Galilean Moons in honor of their discoverer, Italian scientist Galileo Galilei.

What makes Io unique among the other Galilean Moons?

~ Io is unique among the other Galilean Moons because it is geologically active with more than 400 volcanoes. As such, its surface is made of rock, sulfur and molten iron, and it changes annually because of the hot flow.

Which Galilean Moon is of particular interest to scientists because of the suspected presence of liquid water under its surface?

~ Europa is of particular interest to scientists because they believe that it may have liquid water under its surface of rock and ice.

How are the atmospheres of Ganymede and Callisto different?

~ The atmospheres of Ganymede and Callisto are different because, while Ganymede's atmosphere is made up mostly of oxygen, Callisto's atmosphere is made mostly of carbon dioxide and only a small amount of oxygen.
