We missed this amazing image (March of 2016) of the enigmatic Occator Crater on Ceres by the Dawn spacecraft. Scientists studying Ceres’ bright spots determined the spots’ age are only about four million years, some 30 million years younger than Occator crater itself. This suggests that there have been eruptive outbursts of sub-surface salt-water on Ceres over a long period of time and could even still be happening today.
That is an amazing discovery considering that the size of Ceres is smaller than anyone would have expected to have the ability to generate internal heating enough to create such processes.
