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 agree, looking closely this looks like a double exposure. In addition to being brighter on the left side it's also parallel to the horizon. The exposure, viewing geometry and lighting geometry also isn't particularly favorable for detecting plumes. Here is a schematic view showing the context for image 484888253 at 30 times Galileo's field of view:
The small gray box at center shows the camera's field of view. ...But it's interesting that it's only in this image with so short exposition (6.25 ms). In one way this image is 'special': It's the last one in the sequence of 400x400 pixel short exposure image. A 4 minute pause followed before the next sequence of images started (800x800 pixel images). I don't know the details of how Galileo's camera was operated so I don't know if this is of significance - doubt it though. |
