Enceladus Examination Exposes Exhalations

Houston, we have atmosphere:

The Cassini spacecraft has revealed that Saturn's icy moon Enceladus has a significant atmosphere.

The spacecraft unlocked the moon’s secret during recent flybys, NASA’s Jet Propulsion Laboratory announced Wednesday. Scientists, using Cassini's magnetometer instrument for their studies, said the source may be volcanism, geysers, or gases escaping from the surface or the interior.

It's also thought this moon might be the source for Saturn's icy E ring. It would appear to be a busy little moon indeed.
