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.

I looked at Galileo images of Europa and I found only one interesting image.
It's c0484888253 from E19 flyby. It has very low compression and it shows something like haze in the northern polar region of Europa (>70N latitude). I compared this image with another ones from same flyby and no other images is pointing to the same direction and not surprisingly they show nothing. One of them is for comparison in this brightness enhanced version. -------------------- |

Fieseler is the one who was behind the star tracker discovery of objects around Amalthea. I wonder if it is in the engineering data from that instrument.
I looked at Galileo images of Europa and I found only one interesting image. I noticed that while I was putting that mosaic together and assumed it to be a double exposure of some kind. -------------------- |

I notice that the putative haze in the haze image is brighter on the left side, where the surface of Europa is also brighter. That reinforces the double exposure hypothesis.
It seems exceptionally unlikely that such a tenuous plume could be visible with the Sun behind Galileo in an image with the contrast set to show detail on the surface of Europa, which has an albedo of 0.7. |
