Description

The beautiful Pleiades asterism, also known as The Seven Sisters and Messier 45 (M45) among other names, is an open cluster of hot, young stars in the constellation Taurus. 

Interestingly, six of the stars in the blue reflection nebula in the center of the photograph are used for the Subaru logo, Subaru being a Japanese word meaning “unite.” (You can see the correlation more easily if you look at older Subaru logos before 1980.)  So...I felt obligated to add the diffraction spikes!
