This seems like the relevant place to post this (could be wrong): Water plumes from Europa? Apologies if it's already been up. The link to the Science article at the bottom doesn't work for me, does anyone have a working link to the original? Cheers.

Despite the result from the Hubble telescope, a check of old data by Cassini failed to reveal any plumes at Europa.

Yes its ofc data only for the time of the flyby, even so Cassini did not look for any active plumes but for any resulting cloud and the latter would hang around a lot longer. @Vjkane: I am firmly with nprev here, the plumes of Enceladus were actively searched after, and it took quite a while before we got that first backlit image showing them clearly. That something have been going on at Encladus have been known at least since the data from the Voyagers did show something were going on at this moon. A rebuttal is a good sign, hardly anyhing in the scientific world is accepted before someone else have poked your hypothesis hard with a pointy stick. =) |

Just to enlarge on this, the Cassini Phase A report in 1988 clearly shows the degree of interest, declaring Iapetus and Enceladus the two icy satellites of particular interest, noting (section 3.4.2) 'The strange appearance of Enceladus surface and the location of the ephemeral E-ring may be a coincidence, but there is a strong probability that they are connected in some manner, possibly through current eruptive activity on Enceladus' |

And yes carefully phrased as it should be. =) It also serves as a good example that some researchers get one aha moment prior to a mission or a flyby since their minds start to deal with whatever might turn up in that area of space. And it is also a good thing for planning the observations (we've seen some such also for Pluto now which might or not turn out correct when New Horizons get a closer look). =) |
