I speculate that Europa simply cannot be emitting anything more than a tiny fraction of the mass that Enceladus is emitting (if any at all), or else the Voyagers and Galileo would have observed the ring/torus of particles that such outgassing would create. Assuming, of course, that geysers on Europa would propel particles fast enough to escape its gravity and form a ring in the first place...
But, I mean, really -- the smoke ring created by Enceladus is noticeable enough that, if there was such a ring at Europa's orbit, it would have been discovered by now (as, for example, the sulphur torus at Io's orbit was discovered fairly early on). -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain
