Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. Gas giant Jupiter is the solar system's largest world with about 320 times the mass of planet Earth . Famous for its Great Red Spot , Jupiter is also known for its regular, equatorial cloud bands, visible in very modest sized telescopes. The dark belts and light-colored zones of Jupiter's cloud bands are organized by planet girdling winds which reach speeds of up to 500 kilometers per hour. The Cassini spacecraft recorded this dramatically detailed view of Jupiter during its turn of the millennium flyby enroute to Saturn.
