Dawn goes into orbit about Ceres this week, and we can really go into detail. Meanwhile, this shot suggests I may have given up on the "spaceship" idea too soon - and somebody left the airlock open? :)
Too many people are seriously posting the "it's a light!" business.
My guess is it's ice exposed by recent impacts. The surface of Ceres is very dark (albedo ~10%), and quite possibly has ice sub-surface, so you'd go from albedo 10% to albedo 90% if you exposed white ice beneath.
