Two studies published in the journal “Nature” offered new interesting information about the dwarf planet Ceres. Thanks to analyzes of data collected by NASA’s Dawn space probe the authors of these studies claim that the mysterious white spots are composed of salts and that on Ceres there are ammonia-rich clays. The explanations about the materials that make up the white spots may solve a mystery while the presence of ammonia creates another, linked to the origin of this dwarf planet.
