Ceres White Spots

looks like the "spots" are 5KM high mountainshttp://www.jpl.nasa.gov/spaceimages/details.php?id=PIA19578

From my understanding of the NASA link the 5 kilometer high mountains are in addition to the mysterious white spots and not the cause of the spots.

n is currently in orbit about 4,400 kilometers (2,700 miles) above Ceres, but in early August, it will move into a much closer orbit of 1,450 km (900 miles). Planetary scientists hope the closer view will help solve some of the mysteries on this fascinating little world. be patient

I don't know if it required special effort, but I appreciate the fact that your image was shown in correct orientation. The images in the link are shown upside-down, so the craters look like mounds. (or is this something about the way I view them?)

Fortunately I'm viewing on a laptop, so it's not difficult (only inconvenient) to hold it upside-down and see the images in correct orientation, and then the depressions look like craters.

EDIT!

WOW! I went back and looked again, and it is indeed something about how I view them! In the smaller image (the OP), I generally see the craters as craters. But in the link, it depends... If I only view the bottom of the first image, I see craters. If I view only the top of the same image, I see mounds. As I scroll from bottom to top, they all flip from appearing as craters to appearing as mounds.

Is this just me, or do others experience the same, or perhaps the opposite effect?

I start to think it may have something to do with perceived direction of light source...

I'd welcome comments!

this summer when they can get to a lower orbit their test equipment will be able to detect what the white stuff is, my bet is geyser related

A geyser would also make sense. I hadn't thought of that. The images and other data from a lower orbit should settle this.

Until then, everybody should have whipped cream on their dessert!
