It’s ice. This, like the other crater is relatively young. Ice was exposed and ejected by the hit. Older craters have had their ice either sublimated or covered with dust.

Ceres' bright spot made it into the comics yesterday--"Beetle Bailey."

First panel:
Zero: "What are you looking at?"
Beetle (looking through a telescope): "There's a little bright light on the Ceres asteroid."

Second panel:
Beetle: "Nobody knows what it is.
Zero: "Maybe it's the flashlight I lost."
