Abstract

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.

未松弛的陨石坑搅浑了矮行星谷神星的海水

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。

期刊介绍： Nature Astronomy, the oldest science, has played a significant role in the history of Nature. Throughout the years, pioneering discoveries such as the first quasar, exoplanet, and understanding of spiral nebulae have been reported in the journal. With the introduction of Nature Astronomy, the field now receives expanded coverage, welcoming research in astronomy, astrophysics, and planetary science. The primary objective is to encourage closer collaboration among researchers in these related areas. Similar to other journals under the Nature brand, Nature Astronomy boasts a devoted team of professional editors, ensuring fairness and rigorous peer-review processes. The journal maintains high standards in copy-editing and production, ensuring timely publication and editorial independence. In addition to original research, Nature Astronomy publishes a wide range of content, including Comments, Reviews, News and Views, Features, and Correspondence. This diverse collection covers various disciplines within astronomy and includes contributions from a diverse range of voices.
