Photo Sequence of Saturn: February 24, 2009

Saturn's comparatively paper-thin rings are tilted edge on to Earth every 15 years. Because the orbits of Saturn's major moons are in the ring plane, too, this alignment gives astronomers a rare opportunity to capture a truly spectacular parade of moons crossing the face of Saturn. This picture sequence was taken on February 24, 2009, when Saturn was at a distance of roughly 775 million miles (1.25 billion kilometers) from Earth. Hubble can see details as small as 190 miles (300 km) across on Saturn.
