The Pleiades: Facts about the “Seven Sisters” star cluster
space.comChris Mihos, the Worcester R. and Cornelia B. Warner Professor of Astronomy, explained the bright star cluster and a popular skywatching target known as “The Pleiades.”  “The cluster was born only about 100 million years ago (quite recently in terms of the age of our Milky Way Galaxy). As the cluster ages, over hundreds of millions of years, it will slowly lose its stars—some reaching the end of their lives and dying, others drifting away from the cluster and being lost from it entirely as the cluster slowly dissolves to become part of the general population of stars in the Milky Way’s disk,” Mihos said.
