Original Message Something weird is happening on the dwarf planet Ceres, which at 950 kilometers wide is the largest object in the Asteroid Belt. Since its arrival in Ceres’s vicinity earlier this spring, NASA’s Dawn spacecraft has glimpsed mysterious, highly reflective bright spots dotting the surface. No one yet knows what exactly they are or how they got there.

Periodically snapping pictures as it gradually spirals down to a low-altitude “survey” orbit, Dawn has provided a slow-motion zoom-in on the dwarf planet, allowing imaginations to run wild as experts and laypeople alike seek to discern structures and patterns in the low-resolution images. Consequently, many possible explanations for the bright spots have emerged, some more plausible than others, and the ideas shift with each new vista Dawn beams home. The spots could be salts deposited by briny vapors from gushing geysers or, less likely, plumes from water-spewing “cryovolcanoes.”
