Mysterious clear plans for Ceres to the newly interested scholars. It turns out that periodic changes in their clarity, have no connection with the movement of the object rotation is reported by servicing Space.
Bright spots on the dwarf planet Ceres circulating inside the asteroid belt between the orbits of Mars and Jupiter was capture by Dawn spacecraft at the beginning of last year. Over time, the researchers were able to determine that they are composed of smaller spots, namely salts magnesium sulphate. The problem is that periodic changes in their clarity, have no connection with the movement of the rotating Ceres. The causes were so look on the surface.
The most likely explanation is that under the influence of sunlight evaporates from the surface of the globe and affect the brightness of the spot. At night, when the temperature drops, the haze decreases. There are still only a guess, but no-one come up with another explanations.
