With NASA’s Dawn spacecraft set to enter its final and lowest orbit around the dwarf planet Ceres, spectral measurements are enabling researchers to gradually unravel the nature of the numerous mysterious and intriguing bright spots recently discovered, and now they conclude that briny mixtures of ice and salts apparently reside just beneath certain patches of the pockmarked surface and that “water is sublimating” from the surface of an “active crater”.
Indeed, excited scientists report that high resolution images and spectra from Dawn indicate that Ceres is an active world even today, according to a pair of newly published scientific papers in the journal Nature.
