Simply Astonishing: Enceladus, the Jet-Powered Moon

By Nancy Atkinson - October 01, 2010 07:15 AM UTC | Planetary Science

What an astonishing view of Saturn's moon Enceladus, as seen by Cassini! At least four different plumes of water ice are spewing out from the south polar region, highlighted because of the black space behind the Moon. On Twitter, Carolyn Porco said that we see four jets because we're looking down the four tiger stripe fractures crossing the south pole. "How lovely it is to know!" she added.

Cassini was about 617,000 kilometers (383,000 miles) away from Enceladus when it captured this image.
