[space] Ceres: Weird white spots are still weird. … What are the White Spots on Ceres? … ‘You can bet every penny you have planetary scientists are poring over these images and examining every detail. These bright spots are unique; no other such high-contrast feature is seen on airless, rocky bodies. We know Ceres has a lot of water ice under the surface, so it’s not too far out to think that may be what we’re seeing. A recent impact could’ve dredged up ice (we’ve seen that on Mars, in far smaller craters), splashing it around the crater, and also caused that darker spray. But right in the exact center of that big crater (which is clearly much older)? That seems like a big coincidence. Could it be from some sort of vent?’
