      The field of filamentary dust is shown with different sections showing   
      different colors. Stars dot the background. Please see the explanation   
                          for more detailed information.

      Explanation: Is this really the famous Pleiades star cluster? Known for   
      its iconic blue stars, the Pleiades is shown here in infrared light   
      where the surrounding dust outshines the stars. Here three infrared   
      colors have been mapped into visual colors (R=24, G=12, B=4.6 microns).   
      The base images were taken by NASA's orbiting Wide Field Infrared   
      Survey Explorer (WISE) spacecraft. Cataloged as M45 and nicknamed the   
      Seven Sisters, the Pleiades star cluster is by chance situated in a   
      passing dust cloud. The light and winds from the massive Pleiades stars   
      preferentially repel smaller dust particles, causing the dust to become   
      stratified into filaments, as seen. The featured image spans about 20   
      light years at the distance of the Pleiades, which lies about 450 light   
      years distant toward the constellation of the Bull (Taurus).
