Io is named for one of the many lovers of Zeus in classical Greek mythology, and the moon has held a unique place in the development of modern science. Not only was it discovered by Galileo in 1610 and helped inspire the heliocentric model of the solar system, it was also used by the Danish astronomer Ole Rømer in 1676 to make the first measurement of the speed of light.
Covered in over 400 active volcanoes, some of which spew sulfur over 500 kilometers into the sky, Io is painted in brilliant shades of yellow and red from the deposits of sulfur and other chemicals on its surface. Colonizing this moon will be a challenge, but one thing is certain: your colonists will never lack for dramatic vistas.
