Lit by reflected light from Saturn, Enceladus appears to hover above the gleaming rings with its well-defined ice particle jets spraying a continuous hail of tiny ice grains, in this image taken by NASA's Cassini spacecraft in 2006 from a distance of 1.303 million kilometers. The 500 km-wide moon has excited the scientific community and the general public alike, with its potential to harbor an underground habitable environment.
