NASA's Cassini spacecraft provided this enhanced close-up view showing at least two distinct jets spraying a mist of fine particles from the south polar region of Saturn's moon Enceladus. The particles in the plume scatter sunlight most effectively at high Sun-Enceladus-spacecraft angles, or phase angles, making the plumes appear bright.

The image shows the night side of Saturn and the active moon against dark sky. Enceladus is 505 kilometers (314 miles) across.

Some artifacts due to image compression and cosmic rays striking the camera's detector remain as noise in the image.

Cassini acquired the image in polarized green light with its narrow-angle camera on May 4 at a distance of approximately 2.1 million kilometers (1.3 million miles) from Enceladus and 2.3 million kilometers (1.4 million miles) from Saturn.

Cassini took the image at a Sun-Enceladus-spacecraft, or phase, angle of 159 degrees. Image scale is 13 kilometers (8 miles) per pixel.

The Plumes Of Enceladus

Pasadena CA (SPX) Jun 13, 2006
Saturn's little moon Enceladus continues to gush icy particles into orbit, making it one of a select group of geologically active bodies in the solar system, scientists at NASA's Jet Propulsion Laboratory said Monday. Enceladus (505 kilometers, or 314 miles across) is seen here against the night side of Saturn.
