Like previous images, these new photos were taken by NASA's "dawn" detector. When these photos were taken, the dawn was only about 22 miles away from the valley of Ceres. Through photographs, we can see that many bright spots are contrasted with the whole dark landscape, and each highlight shows its inner texture surface.

Although these bright spots initially confused researchers, they soon showed that ice or salt might be part of them. But later, the NASA scientist's explanation was again pointing to the salt. According to NASA, the bright spot is mainly composed of sodium carbonate and ammonium chloride, forming "muddy saline".


The discovery of "dawn" detector made researchers pay close attention to these areas. NASA says the spacecraft is completing its second expansion mission at Ceres, taking time to photograph images at a distance of only 22 miles from the surface of a dwarf planet. In addition, "dawn" is collecting the neutron spectrum, gamma ray, visible / infrared spectrum and gravity information of Ceres. The targets of NASA are mainly on Urvara and Occator craters.

Unfortunately, this task is only a few months away. NASA announced that the "dawn" detector will run out of its main fuel between August and October, and then propellers will no longer be able to maintain the direction of the spacecraft. This will make "dawn" leave the orbit of Ceres, but it will no longer be able to communicate with researchers on earth.
