      A rainbow is pictured over the sea between an island and land. A series   
      of light rays appears to connect the horizon to the rainbow. Please see   
                  the explanation for more detailed information.

      Explanation: Yes, but can your rainbow do this? Late in the day, the   
      Sun set as usual toward the west. However, on this day, the more   
      interesting display was 180 degrees around -- toward the east. There,   
      not only was a rainbow visible, but an impressive display of   
      anticrepuscular rays from the rainbow's center. In the featured image   
      from Lekeitio in northern Spain, the Sun is behind the camera. The   
      rainbow resulted from sunlight reflecting back from falling rain.   
      Anticrepuscular rays result from sunlight, blocked by some clouds,   
      going all the way around the sky, overhead, and appearing to converge   
      on the opposite horizon -- an optical illusion. Rainbows by themselves   
      can be exciting to see, and anticrepuscular rays a rare treat, but   
      capturing them both together is even more unusual -- and can look both   
      serene and surreal.
