I'm a little confused here.
This is the first close up picture of a comet ever taken, AFAIK. But because they're seeing unexpected features, they're chalking it up to this comet being an aberration.
That is completely bassackwards. They should be examining their predictions and trying to see how the visual confirmation fit into current hypotheses. Instead they're throwing this one out as EXTRAordinary and keeping the old models intact.
Sorry, just read a paragraph I must have missed.
What?
You got something against the comet head being made of dirty ice? :^)
I think you're right. Some concept revision appears to be indicated.
Well said.
