Amazing picture. That crater on Thule, the smaller one, is curious, the impact should have obliterated it. Maybe it's not a crater but a depression left over from when it was attached to Ultima in a different place, before it rolled into the current configuration. There's a faint white ring on Ultima in the right spot. (I am not at all an astronomer, just guessing)
