Would a haze indicate ice? The haze is confined to the crater itself. I'm going with a gas escaping from beneath the surface. Possible that Ceres is still active?
Dawn has also found that Ceres is slightly smaller than expected, making it roughly 4% more dense than scientists had thought, Russell reports. And the obliquity, or tilt, of its orbit is the reverse of what scientists had anticipated

I really do hope it's ice...otherwise...there might be a whole lot of suicides on ATS.

Leaving this for future reference.

It does have activity, water vapour that's been observed by the Herschel telescope,

It could be underground salty water rising to the surface and evaporating, leaving the bright deposits.

Maybe it's a salt flat laid down by water that sublimated away, leaving salt deposits behind.
My second choice would be a frozen deposit of salty/mineraly-rich water (so I suppose "Ice" is my second choice, but I'm talking about water ice with a very very high concentration of mineral salts -- so my true second choice would be somewhere in between "Salt" and "Ice"). Just plain water ice would have a tendency to sublimate away into space rather than being persistent, but maybe if that water was high dissolved mineral salts content, then possibly that salty mineral component is preventing it from sublimating so easily.

On Cere's they are now dropping the idea of a salty bed for the bright spots, and saying that it is ice
