It is the most famous star cluster on the sky. The Pleiades can be seen without binoculars from even the depths of a light-polluted city . The Pleiades contains over 3000 stars, is about 400 light years away, and only 13 light years across. Quite evident in the above photograph is the blue reflection nebula that surrounds the bright cluster stars. Low mass, faint, brown dwarfs have recently been found in the Pleiades .
