| Date: 11/01/2008 | Deepskystacker: Average | Name: The Seven Sisters - Pleiades - M45 |
| Location: Golden Grove Western Australia | ||
| Camera: Canon 20D | The
nine brightest stars of the Pleiades are named for the Seven Sisters of
Greek mythology: Sterope, Merope, Electra, Maia, Tavgete, Celaeno
and Alcyone, along with their parents Atlas and Pleione. As
daughters of Atlas, the Hyades were sisters of the Pleiades. The
English name of the cluster itself is of Greek origin, though of uncertain
etymology.
Studies show that the dust responsible for the nebulosity is not uniformly distributed, but is concentrated mainly in two layers along the line of sight to the cluster. These layers may have been formed by deceleration due to radiation pressure as the dust has moved towards the stars. |
