There's one image, did you see more than one? And to me... it looks like someone took a blurry picture of a campfire.
The only one I've seen is the picture that BWC posted above. I believe anything else you find on the web is simply a rendering of what they think they look like.
Cool, sure. I wouldn't call it some amazing image, though(amazing that they got it, but not like it's some crazy beautiful picture). Now if they had a focused, detailed image... that's a different story.
I'm a science guy through and through, and I just felt like it was underwhelming. Very cool accomplishment, though. Not trying to take anything away from them in that regard.
