NEOWISE has the ability to determine whether a centaur has a dark surface or a shiny one that reflects a lot of light. By combining the reflectivity data with what was already recorded about the colors of the objects, scientists were able to solve the mystery. Visible-light data has revealed centaurs generally to be either blue-gray or reddish in hue. NEOWISE revealed that most of the blue-gray objects are dark, a clear indication that the objects are comets.
