(U of AK/U of AZ/NOAO via Wired Science) (…) The Pleiades are an open cluster easily visible to the naked eye. The cluster is dominated by several hot, luminous and massive stars. The blue nebulosity surrounding the brightest stars are due to blue light from the stars scattering off of dust grains in the interstellar gas between us and the stars. The cluster is also known as the ‘Seven Sisters’. And in Japan it is called Subaru. The image was generated with observations in the B (blue), V (green), and I (red) filters. In this image, North is right, East is up.
