I try to avoid linking to my own blog (figuring that if you guys think something's worthwhile you'll post a link, else not!), but in doing so today it's only to point you all to some amazing detective work done by another UMSFer, Ted Stryk:
An "amateur" discovers moons in old Voyager images

Wow.

Real proud of Ted. What a great group to be part of. I'm not worthy.

Jeez... that's truly amazing work, Ted. I know how modest you are about your image processing work, so any recognition and praise you get for this find will be well deserved.

The color is rather tortured...the very left most part is simply based on the rest of the image, soon after the first moon image it becomes Orange-Blue with a tweaked "Green" fudged from an average of the two available images, then Orange-Blue-Violet with Blue tweaked to be more like Green, and, finally, just beyond the second "shadow", it becomes Orange-Green-Violet. In addition to try to force the non OGV portions of the image to behave like the OGV section, the transitions are done gradually over about 25 pixels in order to prevent discontinuities.

Awesome and congratulations!!

Very well done! Shows how a thorough search can pull new information out of old data!

Here is a single shot of the transit with consistent OGV color (except for lining up moon and shadow color, which had to of course be done).

That is astounding stuff. Makes me think about what else might be lurking in the PDS awaiting future discovery...

Wow...all I can do is likewise, Ted. Amazing work!

Emily's title for her article is extremely apropos..."amateur" definitely needs to be in quotes!

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

So much, so much. I have had this one up my sleeve for quite a while, and I have a few more things in the pipeline (none on this scale though). Given that these were much-studied images, who knows what might be lurking in other shots. I think Voyager and other old data are hiding many things under their reseau paterns and gunky vidicon noise. Modern missions no doubt hide things via the pure volume of data they return.

That must have come from EGD.
