This will be where we talk about the data as it arrives over the next 20 months or so.
-------------------- 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.

Another mechanism comes to my mind for the white lines we see. If these bodies are made of lesser balls of aggregated material, which originally may have clumped before being added to Última and Thule, they would have boundaries. Any energetic impact that could have partially melted the surrounding material of the impact area could cause a melting, which would naturally flow through these discrete boundaries filling them up and causing contrast of materials.
As a result, even if there was a full melting of the clump surface, boundary would still differentiate. And the big circle in Última seems exactly that: melted surface which slightly seems a done with a surrounding ring, but the flowing material escapes this boundary - this seems apparent on the right side. Against this, is where would be the impact crater causing any such melting. Thule has a crater, but Ultima seems devoid of any such originator in the area. |

I have one observation I haven't seen mentioned explicitly here. The constituent lumps of the larger lobe Ultima all seem to be about the same size, causing it to resemble a bag of oranges. I have absolutely no suggestions as to why that might be. |
