       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.

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