What a great look at 67P/Churyumov-Gerasimenko by Rosetta. The view is from 102 km / 63 miles away on 11 Aug 2014.
If it (what I call the top) would just rotate a wee bit more we could get a look inside that crater on the end. Is there a central peak or any signs of melting in there? That would be composition dependent, good clues.by
