The Pleiades Star Cluster


Perhaps the most famous star cluster on the sky, the
can be seen without binoculars from even the depths of a
light-polluted city.

Also known as the Seven Sisters and
the Pleiades
is one of the brightest and closest
open clusters.

The Pleiades
contains over 3000 stars, is about 400 light years away,
and only 13 light years across.

Quite evident in the
above photograph are the
blue reflection nebulae
that surround the brighter cluster

Low mass, faint, brown dwarfs have also
been found in

(Editors' note: The prominent
diffraction spikes are caused by the telescope itself and may be either distracting or provide aesthetic enhancement, depending on your point of view.)
