The Pleiades (the Seven Sisters, or officially M45) is a tight cluster of stars that is visible to the naked eye on dark nights. Here, the group is shown through the wide-field view of the Mosaic camera on the WIYN 0.9-meter telescope on Kitt Peak, Arizona. Blue, green, and red filters were applied.
The cluster of hot, big stars is accented by blue nebulae that are formed as the starlight scatters off dust particles in the interstellar space between the luminous bodies. The stars of Pleiades are considered middle-aged, and they are located in the constellation Taurus. The cluster is among the nearest to Earth.
The Pleiades are known as Subaru in Japan, a name that was adopted by the car company. Many cultures had rich folklore about the star cluster, from the Norse people to the Berbers, Arabs, Hebrews, and of course the Greeks, who called them the Seven Sisters.
