This simply wonderful image was taken by the NASA - Dawn Spacecraft on February, 19, 2015, and shows us the so-called "Dwarf-Planet" 1-Ceres from a distance of nearly 29.000 miles (such as approx. 46.670,86 Km). Here, we can (finally!) see that the brightest "Spot" (already known) that exists on 1-Ceres, has a Dimmer (---> less bright) Companion, which apparently lies in the same Basin (---> large Impact Crater).
What actually are these two "Bright Spots"? Surfacing Frozen Water Ice Pools? True "Flares", whose origin in still unknown? Nobody knows for sure. Now.
But in a few days we might know more... However, the NASA - Dawn Spacecraft is due to be captured into orbit around 1-Ceres on March 6, 2015.
