…and speaking of pieces. The 11th Dust Workshop is going on now (18-20 Mar 2025, Venice, IT). The “11th” refers to 2015, due to the Rosetta mission to Comet 67P/Churyumov-Gerasimenko. While it’s true that Rosetta advanced comet studies far beyond the status quo, there’s still much to find, let alone discuss. The meeting program:
