QUOTE the sulphur torus at Io's orbit was discovered fairly early on From earth based observations? Or the Voyager flybys? |

Voyager flybys, as I recall. I'm just thinking that any really energetic geysers on Europa would eject enough water (ice crystals) to create an observable torus. I grant you, the sulphur torus is very energetically enriched, constantly... but also as I recall, many of the probes that have gone to or past Jupiter have had rather sensitive spectrometers that would have detected even a very tenuous water ice torus in Europa's orbit.
I'd think that such detection would be possible from Earthbound telescopes, too, at this point -- but I could be wrong. -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain
