It is among the nearest star clusters to Earth and is the cluster most obvious to the naked eye in the night sky . </P> <P> The cluster is dominated by hot blue and extremely luminous stars that have formed within the last 100 million years . A faint reflection nebulosity around the brightest stars was thought at first to be left over from the formation of the cluster (hence the alternative name Maia Nebula after the star Maia), but is now likely an unrelated foreground dust cloud in the interstellar medium, through which the stars are currently passing . </P>
