That's quite an image, Nick, and a pretty compelling paper about it. You really had me going, saving the punchline about low latitudes for the very last sentence.

Predictably, I had to take a look for myself in the raw data....

The 100% version is worth downloading, and it's worth looking at at 200%. Where your "constrasty" version has abundant areas that appear motion-blurred, I must confess that in my version I'm hard-pressed to see anything that's unambiguously motion-blurred--fluid "caught in the act". Instead, I think I'm seeing light material peeking through a dark surface layer. What really cast some doubt in my mind was spotting several sharp channels right-of-center that cut across light areas which are blurred in the original.

What am I missing?
