Unrelaxed craters muddy the waters of the dwarf planet Ceres

Ceres’s surface is ice-rich and warm, so we expect craters to viscously flow. Yet most of Ceres’s craters are not shallow. A new model that includes a stronger, progressively dirtier icy crust, frozen from an ancient ocean, may reconcile this discrepancy.

不松弛的陨石坑使矮行星谷神星的水域变得浑浊



谷神星的表面富含冰且温暖,因此我们预计陨石坑会粘性流动。然而谷神星的大部分陨石坑并不浅。一种新模型可能会消除这种差异,该模型包括由远古海洋冻结而成的更坚固、逐渐肮脏的冰壳。
