To me the current surface still looks old. I see Ceres as a body that was one-time active but has now cooled to a point that the surface is no longer active. The surface certainly looks old and battered yes but much younger than a lot of other icy bodies that have been studied. For floating in the asteroid belt, Ceres appears remarkably smooth in a lot of places suggesting some amount of occasional resurfacing in those areas in geologically recent times. I haven't heard much about the possibility of a periodic atmosphere around Ceres recently. Has there been any more debate on this? We are unfortunately nearly in the dead of winter on Ceres right now. Has this been laid to rest since that article? There wasn't ever much as far as details on the speculation anyway. -------------------- |
