  • Spectral characteristics can be used to link asteroid and meteorite materials. Here, the authors show in-situ mid-infrared data of a boulder on asteroid Ryugu, compared with laboratory spectra of various meteorites, indicate that Ryugu experienced strong aqueous alteration prior to dehydration.

  • Observations from the Lucy spacecraft of the small main-belt asteroid (152830) Dinkinesh reveals unexpected complexity, with a longitudinal trough and equatorial ridge, as well as the discovery of the first contact binary satellite.

  • A bright outburst of activity from the nucleus of comet 67P, observed by Rosetta in July 2015, is traced back to a cliff that partially collapsed at the same time as the outburst, establishing a link between the two events. The collapse has also exposed the fresh ice present under the surface.

  • Bright deposits, at least one of which is made up of water ice, are detected in the permanent shadows of 10 craters in the northern polar area of the dwarf planet Ceres. This means that Ceres traps water ice at high latitudes, like the Moon and Mercury.

  • The ‘onion-like’ stratification of the two lobes of the comet 67P/Churyumov–Gerasimenko reveals that its unusual shape is the result of a gentle collision merging two kilometre-sized objects in the early stages of the Solar System.

  • The size and spatial distribution of pits on comet 67P/Churyumov–Gerasimenko, which are active and probably created by a sinkhole process, imply that large heterogeneities exist in the physical, structural or compositional properties of the first few hundred metres below the current cometary surface.

  • Gravity and shape measurements for Ceres obtained from the Dawn spacecraft mission show that it is in hydrostatic equilibrium with its inferred normalized mean moment of inertia of 0.37, suggesting that Ceres has a rocky chondritic core overlaid by a volatile-rich icy shell.
