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.

    [2]The famous Pleiades star cluster is shown surrounded by dust. Dust
      near the bright stars reflects blue light, but dust further away
       appears more red. Please see the explanation for more detailed
                                information.

   Explanation: The well-known Pleiades star cluster is slowly destroying
   part of a passing cloud of gas and dust. The [4]Pleiades is the
   brightest [5]open cluster of stars on Earth's sky and [6]can be seen
   from almost any northerly location with the [7]unaided eye. Over the
   past 100,000 years, a field of gas and dust is moving by chance right
   through the [8]Pleiades star cluster and is causing a strong reaction
   between the [9]stars and dust. The passing cloud might be part of the
   [10]Radcliffe wave, a [11]newly discovered structure of gas and dust
   connecting several regions of star formation in the [12]nearby part of
   our [13]Milky Way galaxy. Pressure from the stars' light significantly
   repels [14]the dust in the surrounding blue [15]reflection nebula, with
   smaller [16]dust particles being repelled more strongly. A short-term
   result is that parts of the dust cloud have become [17]filamentary and
   [18]stratified. The featured deep image incorporates nearly 9 hours of
   exposure and was captured from [19]Utah Desert Remote Observatory in
   [20]Utah, [21]USA, last year.
