Ceres has been an interesting crash course in dwarf planet weirdness for a while now, with data on ice, salt, water, bright spots, and more slowly trickling out of the Dawn spacecraft. Now a study led by Georgia Institute of Technology and published in Nature Geoscience unveils more about water on Ceres.

The study led by Georgia Tech Assistant Professor and Dawn Science Team Associate Britney Schmidt provides more proof that Ceres, a dwarf planet residing in the asteroid belt, is a mix of rock and ice.

The team used data from NASA’s Dawn spacecraft to identify three different types of landslides on Ceres. Type I landslides are round, large, and occur at higher altitudes, which is where researchers assume most of Ceres’ ice is located. These types of landslides look like rock glaciers and icy landslides.

Type II is most common and occurs at mid-latitudes. These landslides look like deposits from avalanches on Earth and are thinner and longer than Type I landslides. The researchers fondly nicknamed this type “Bart” because its elongated appearance looks like Bart Simpson’s head from the TV show The Simpsons.
