Saturn's massive atmosphere appears poised to crush little Enceladus in this image. Many fascinating details are visible in the gas planet's sinuous bands, such as a giant, eye-shaped storm that circles the south pole. The diameter of Enceladus is 499 kilometers, (310 miles).
The image was taken in visible blue light with the Cassini spacecraft narrow angle camera on Oct. 12, 2004, at a distance of about 5.3 million kilometers (3.3 million miles) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 68 degrees. The image scale is 31 kilometers (19 miles) per pixel.
