Une équipe de planétologues a utilisé la puissance du télescope Webb dans l'infra-rouge pour regarder de près les petits satellites internes des systèmes de Uranus et de Neptune, afin de caractériser leur composition de surface. On en sait plus, mais des questions demeurent sans réponse. Ils publient leurs résultats dans The Planetary Science Journal.
