APOD 2.4

Pictured is Pleiades or Seven Sisters star cluster which is located some 400 light-years away.  It is well known for its incredible blue reflection nebulae.  This photo shows the sky toward the constellation Taurus and the Orion Arm of the Milky Way.  The star cluster is located at the upper left of this photo.  But lesser known nebulae are located along this region's molecular cloud.  This includes the "bird-like visage" of LBN 777 located near the center.  VdB 27 at the lower right is the small bluish reflection nebula.  It is associated with the young, variable star RY Tau.  At the distanced of the Pleiades, the 5 panel mosaic spans nearly 70 light-years.
