The possibility of an endogenous source—a process within Ceres—was initially considered. The dwarf planet is known for cryovolcanism, a phenomenon where subsurface liquids, mainly briny water ...

After tracking a puzzling X-ray signal from a dying star for decades, astronomers may have finally explained its source: The ...
