As I look at the icy trails in Cassini's recent pics of Enceladus, many questions come to mind:<br /><br />Could Enceladus be a comet?<br /><br />What ice vs. dirt consistency is required for an object to be called a comet?<br /><br />Do comets have geysers?<br /><br />How long can an object continue to emit these glorious trails of icy matter before its supply runs out?<br /><br />Were the geysers always there? Are there any old pics of Enceladus <i>sans</i> geysers? <div class="Discussion_UserSignature"> <p><font size="2" color="#ff0000"><em><strong>I'm a recovering optimist - things could be better.</strong></em></font> </p> </div>
