Astronomy Picture of the Day

   [1]Discover the cosmos! Each day a different image or photograph of our
      fascinating universe is featured, along with a brief explanation
                    written by a professional astronomer.

    cluster taken from Florida in the USA. Please see the explanation for

   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 [4]Pleiades can be seen without binoculars from even the depths of
   a [5]light-polluted city. With a long exposure from a dark location,
   though, the dust cloud surrounding the [6]Pleiades star [7]cluster
   becomes very evident. The [8]featured exposure, taken from Florida,
   USA, covers a sky area several times the size of the full [9]moon. Also
   known as the [10]Seven Sisters and [11]M45, [12]the Pleiades lies about
   400 light years away toward the constellation of the Bull ([13]Taurus).
   A [14]common legend with a [15]modern twist is that one of the brighter
   stars faded since the cluster was named, leaving only [16]six of the
   sister stars visible to the unaided eye. The actual number of
   [17]Pleiades stars visible, however, may be more or less than seven,
   depending on the [18]darkness of the surrounding sky and the
   [19]clarity of the observer's eyesight.
