TL;DR: Measurements of Ceres indicate widespread ammoniated phyllosilicates across the surface, but no detectable water ice, which suggests that material from the outer Solar System was incorporated into Ceres, either during its formation at great heliocentric distance or by incorporation of material transported into the main asteroid belt.

TL;DR: Spectra of these bright areas in the Occator crater on Ceres are consistent with a large amount of sodium carbonate, constituting the most concentrated known extraterrestrial occurrence of carbonate on kilometre-wide scales in the Solar System.

TL;DR: In this paper, the authors describe a system at equilibrium by a time-independent distribution function and two potentials of the modified Poisson and collisionless Boltzmann equations derived from gravity in the weak field approximation.

TL;DR: Observations of water ice on the surface of comet 67P/Churyumov–Gerasimenko are reported, appearing and disappearing in a cyclic pattern that follows local illumination conditions, providing a source of localized activity.

TL;DR: In this paper, the authors used the VISible and InfraRed Mapping Spectrometer on board the Dawn spacecraft to detect an organic absorption feature at 3.4 micrometers on the dwarf planet Ceres.
