Cassini captured this arresting view of Saturn just before its tiny moon Epimetheus crossed into the blinding glare of the planet's sunlit crescent and was lost.

As it orbits Saturn, Epimetheus, only 116 kilometers (72 miles) across, hugs the outside edge of the narrow F ring, beyond the orbit of Pandora. The F ring is the brightest ring feature seen here. Saturn's southern hemisphere is softly lit by sunlight reflected off the rings.

A less obvious feature in this view is the planet's shadow, which begins to darken the inner regions of the rings at left.

Cassini took the image in visible light with its narrow-angle camera on June 9 at a distance of approximately 4-million kilometers (2.5 million miles) from Epimetheus and 4.1 million kilometers (2.5 million miles) from Saturn.

The Sun-Epimetheus-spacecraft, or phase, angle is 161 degrees. Image scale is 25 kilometers (16 miles) per pixel on Saturn.

Cassini Uncovering More Secrets Of Saturn Rings
Pasadena CA (SPX) Jul 06, 2006
New images by the Cassini spacecraft of Saturn's diaphanous G and E rings are yielding clues about their structure and formation. A sequence of recent Cassini images, compiled into a brief movie by the spacecraft's imaging team, shows an arc of bright material looping around the inside edge of the G ring, a tenuous 7,000-kilometer (4,400-mile) wide band of dust-sized icy particles lying beyond the F ring by 27,000 kilometers (16,800 miles).
