Sunlight bounces on a highly reflective material

New picture was taken by spacecraft Dawn 14 and 15 April. Here the "spots" like reflective element appear to the right of the dwarf planet. The researchers are still fond of the mysterious brilliant spots on the dwarf planet Ceres.

Is it maybe a geyser?
Now, Naas needs help in solving the mystery.
Naas now asks the public for help solving the mystery of the brilliant dots on the dwarf planet Ceres that lies in the asteroid belt between Mars and Jupiter.
Not a spot but several

In March, Naas reported that two light spots on Ceres were discovered. In May, Naas’s craft Dawn put in orbit around the planet and took close-up images of the light phenomenon. It turned out to consist of a larger bright reflective spot and a group of several smaller ones.

"Dawn scientists can now conclude that the intensity of these brilliant dots is because sunlight bounces on a highly reflective material on the surface, possibly ice," said Christopher Russell, belonging to the Dawn team, earlier in May.
However, the pictures were taken at a distance of 7,200 kilometers and it is too far away for the researchers to be completely safe. Naas now finds on his website that before Dawn's car arrives closer to Ceres, which takes a few months, it's up to anyone to guess what the spots are.

Naas then raises some options that ordinary people can vote for. Perhaps the spots are volcanoes? Or salt deposits?
The most popular option right now among those who voted on Naas’s site is the last, and perhaps most mysterious - "Other".
Ceres was discovered in 1801 by the Italian Giuseppe Piazzi, and is the first dwarf planet discovered.
