Cool image time! The Dawn image at the right, cropped to show here, was taken on April 19, 2016. It shows the crater Oxo on Ceres and is especially intriguing because it not provides high resolution imagery of the crater’s bright rim, the second brightest feature on Ceres, it also shows how the southeastern part of the crater’s rim has literally slide down into the crater, leaving behind a gaping rombus-shaped pit.
The slumping, combined with the bright material on the rim, is more evidence that at some point in the past Ceres was geologically active.
