description Celaeno Nebula Overview
The Celaeno Nebula is a reflection nebula located within the Pleiades star cluster (M45) in the constellation Taurus. It is directly associated with Celaeno, a blue-white B-type star that received its official name from the International Astronomical Union in 2016. The nebula appears blue because the fine cosmic dust particles in the interstellar medium preferentially scatter the short wavelengths of light emitted by the hot star. Like other nebulosity in the Pleiades, it is not a site of star formation but rather a coincidental dust cloud the cluster is passing through.
