Pleione

Its story

Pleione is one of the sisters of the Pleiades, the most famous cluster in the sky, in Taurus. It is a variable blue star spinning so rapidly on itself that it periodically flings out a disk of gas around its equator — a rare phenomenon that has made it an enduring subject of study. At 382 light-years, it shines at the very edge of human visibility, almost lost in the combined glow of its more celebrated sisters.
