Comment: |
The Pleiades is one of the most well known and beautiful open clusters. M45 contains about 500 stars within the diameter of 12 light years. The cluster is surrounded by blue nebulosity illuminated by the light reflected from its stars. The nebulosity is part of an interstellar molecular cloud through which the cluster is passing through and it is not related to M45. It is not a remainder of the nebula from which the Pleiades once formed, because radial velocities of the cluster and the cloud are too different. The Pleiades cluster is relatively close to us, it is only 370 ly distant. |
