Named after the king of the Roman gods, Jupiter is the giant of our solar system. Its stripes are dark belts and light zones created by strong east-west winds in the planet's upper atmosphere. Within these areas are huge storm systems that have raged for years. The Great Red Spot, one such giant spinning storm, has existed for at least three centuries.
