My guess is that the rays are actual streamers of material instead of sun rays. This somewhat reminds me of cometary jets. Are cometary jets presumed to be liquid or vapor generally? I suppose a geyser on earth can also emit either vapor (condensing into steam) or liquid water. Would a determination of ice particle size help constrain whether it was likely to be steam or water?

QUOTE (scalbers @ Nov 29 2005, 02:44 PM) Would a determination of ice particle size help constrain whether it was likely to be steam or water?  This is really exciting news! How much evidence does this point to a subsurface ocean, if only periodic? What are the odds of doing spectrometer study of the E ring to look for ammonia-based impurities... and perhaps trace amounts of amino acids? If there was a chance of organics in the plumes, how urgent would it be to send an "iceclipper" style mission to sample the plumes directly for signs of complex chemistry? |
