Newsflash! Ceres Resolved ...Or Not

This is just a fast post to tie in with the official news from NASA that reveals the bright lights on Ceres are - salt.
Far be it for me to question  NASA , but is that it ?
I'm sure I saw another release that said it was a mixture of a salt (magnesium sulfate) and dirty ice thrown above ground by a collision - or multiple collisions.

In a nutshell, Ceres could provide a new source of  health-giving spa waters...

The assertion is that it derives from some form of subsurface ocean (quite a common theme in our moons and smaller worlds , these days).
Estimates say that Ceres is approximately 25% water, most of which is locked in as subsurface ice, allegedly.
There seems to be a lot of discussion about the incredible refractive index (let's not forget that some of these areas are 6 miles across and glowing...)

So there we have it, and thank you for resolving the mystery, NASA.
Of course, this is not a full and defintive answer...

130 'spots' have been identified...
