DescriptionMessier 45, commonly known as the Pleiades or Seven Sisters, is found in the constellation Taurus. M 45 is surrounded by a dusty reflection nebula, which accounts for its blue coloration. The pinkish red coloration is due to an ionized gas component. The structure in the nebulous regions is created by interstellar magnetic fields.
