Wing Ip just had an interesting Iapetus-related paper published in GRL.

I guess this idea probably originated with those images of Pan from a while back. If this proposed ring actually existed, it must have been very long-lived to last beyond the main era of heavy bombardment (either that or it was impact generated towards the end of said era).
The only thing that bothers me a bit about this idea is that, looking back at some of the images from the New Year's encounter a year and a half ago, there seem to be places in the ridge where the structure shows multiple parallel linear features -- which seems a bit more complex than this theory would seem to allow. However, given that we can't really see what those features are, they can't rule out the idea. |
