How can Uranus be used to indirectly study its moons and identify if they possess subsurface oceans? This is what a recent study presented at the 56th Lunar and Planetary Science Conference hopes to address as a team of scientists investigated using passive radar sounding methods from Uranus to study its five largest moons: Miranda, Ariel, Umbriel, Titania, and Oberon. This study has the potential to help researchers better understand the formation and evolution of Uranus and its largest moons despite a spacecraft not currently visiting Uranus.
