STAR CLUSTERS

The Pleiades

The Pleiades or Seven Sisters is one of the most instantly recognizable shapes in the night sky. It is an open cluster of more than a thousand stars, but we only see its brightest members. To me it always looks like a question mark. The Pleiades have captivated humans from ancient times to the modern. The Pleiades feature prominently in the starlore of Greek, Druid and Native American astronomical traditions.
