Image of the Day: Enceladus & Company Orbit a Black Saturn


This image captures three illuminated moons as a black Saturn looms in the shadows. Only the planet's rings are visible but its shape can be traced from the way it partially obscures its rings and one of its moons.

The large foreground moon is Rhea at 1528 kilometres across. Nearly a third of Rhea's size, sun-lit Enceladus is on the right. Dione, at 1123 kilometres wide, is to the left partially blocked by a black, night-cloaked Saturn.

The photo was taken by NASA's Cassini spacecraft in April. Cassini has been exploring Saturn's 62 known moons since it reached the ringed planet in 2004.
