Ceres' Missing Large Craters
Published on Jul 26, 2016 Ceres' lack of giant impact basins presents a puzzle to scientists. They expected to observe more large craters on the dwarf planet than have been found by NASA's Dawn mission. Researchers are investigating a variety of processes that might have caused the appearance of the largest basins to be softened or erased over time.
