I remember those. I looked at the link to see if I was right about the Galileo spacecraft imaging them. It turned out I was right but I'd forgotten how long its been since that image was captured...fifteen years! <div class="Discussion_UserSignature"> <p><strong>My borrowed quote for the time being:</strong></p><p><em>There are three kinds of people in life.
