  • Absorption features in Io's reflectance spectrum suggest that frozen SO2 molecules are present on the surface of Io as free frost; this may have important implications for Io's atmosphere.

  • Giant icy volcanos (cryovolcanos) on Pluto are unique in the imaged solar system and provide evidence for unexpected, active geology late in Pluto’s history.

  • JWST/NIRSpec spectra are used to analyse the surfaces of Centaurs, revealing two main compositions: those with refractory materials and water ice and those rich in carbon-based materials. Strong surface weathering due to thermal processing may be responsible.

  • The near-infrared spectrometer onboard JWST has detected CO2 and CO ices on 56 and 29 trans-Neptunian objects, respectively, indicating two dominant compositional types among them. These compositional differences suggest varied formation regions in the protoplanetary disk.

  • The surface of Hyperion has a large region of high albedo with the signature of H2O ice and another zone of albedo about a factor of four lower. Observations of the surface in the ultraviolet and near-infrared spectral regions with two optical remote sensing instruments on the Cassini spacecraft detail that the low-albedo material has spectral similarities and compositional signatures that link it with the surface of Phoebe.

  • In the Spitzer Space Telescope’s 16 years of operation, it observed many Solar System objects and environments. In this first Review Article of a pair, Spitzer’s insights into comets, centaurs and Kuiper belt objects—all remnants of the Solar System’s formation—are summarized.

  • A network of parallel ridges on the northwestern border of Sputnik Planitia on Pluto are the traces of debris material deposited by a glaciation of icy nitrogen that happened early in Pluto’s history, and left there once the N2 ice disappeared by sublimation.
