Explanation:
Have you ever seen the Pleiades star cluster?
Even if you have, you probably have never seen it as large and clear as this.
Perhaps the most famous star cluster on the sky, the bright stars of the
Pleiades
can be seen with the unaided eye even from the depths of a
light-polluted city.
With a long exposure from a dark location, though,
the dust cloud surrounding the
Pleiades star
cluster becomes very evident.
The featured 18-hour exposure, taken from
Bory Tucholskie,
Poland
covers a sky area several times the size of the full
moon.
Also known as the Seven Sisters and
M45,
the Pleiades lies about
400 light years away toward the constellation of the Bull
(Taurus).
A common legend with a
modern twist is that one of the brighter stars faded since the cluster was named, leaving only six of the sister stars visible to the unaided eye.
The actual number of
Pleiades stars visible,
however, may be more or less than seven, depending on the
darkness of the surrounding sky and the
clarity of the observer's eyesight.
