摘要

谷神星表面富含冰且温暖，因此我们预计环形山会粘稠地流动。然而，谷神星的大多数环形山并不浅。一个新的模型包含了一个从远古海洋冻结而成的更坚固、逐渐变脏的冰壳，可能会调和这种差异。

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.
