All about Io
Io is one of Jupiter’s moons and is the most volcanically active object in the solar system. Its volcanoes shoot sulphur high into space.
Its surface is covered with yellow, orange and red patches created by sulphur.
Io is constantly reshaped by volcanic eruptions and lava flows. Its volcanoes are powered by the tug of gravity from Jupiter and nearby moons, which stretches and heats the inside of Io.
