Ice spires on Callisto. Illustration of ice spires (around 100 metres tall) on the surface of the Jovian moon Callisto. It is thought that these spires formed from an ancient impact billions of years ago. They are very slowly eroding over time, the ice subliming and dust within the ice accumulating to absorb sunlight and continue the erosion. | |
