This is Pleiades, also known as the Seven Sisters. According to the ancient Greeks, Pleiades are the children of Atlas, the Titan that was condemned to guard the heavens, and Pleione, daughter of Oceanus. The sisters are Alcyone, Asterope, Taygeta, Celaeno, Electra, Merope and Maia. Asterope is actually a double star, which makes them eight. The blue veil is a passing dust cloud in this open star cluster. It is approximately 440 light years away from Earth.
