The
most famous star cluster in the sky, The Pleiades
can be seen without binoculars from even the
depths of a light-polluted city. Also known as
the Seven Sisters and M45, 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 bright
cluster stars.
