The Missing Ceres Craters Mystery | Space News
Scientists studying the surface features of the dwarf planet Ceres are proposing a new theory for its geologic history. One problem facing NASA investigators is the absence of exceptionally large so-called impact basins from collisions, which planetary scientists believe must have occurred over the dwarf planet’s supposedly ancient geologic age. Rather than considering that these giant impacts may have simply never happened, the investigators are proposing that mysterious processes have smoothed the surface of Ceres, erasing its largest craters over time. In this episode, we explore the evidence that electrical processes rather than periodic impacts created Ceres' craters.
