M45: The Pleiades Star Cluster


Explanation:
Perhaps the most famous star cluster on 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 brighter cluster
stars.

Low mass, faint, brown dwarfs have also
been found in
the
Pleiades
.
