In an article on space.com, astronomers Benjamin Zuckerman and Inseok Song disclose that their team has discovered unusually thick clouds of dust around the star HD 23514. This star is in the Pleiades cluster, and is about 100 million years old. At that age most of the ‘primordial’ dust should have dispersed. This leads the researchers to believe that the dust is the result of collisions between rocky bodies.
