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 featured image shows crepuscular rays emanating from below the
    horizon and appearing quite red. Please see the explanation for more
                            detailed information.

   Explanation: What's happening behind that island? Things both expected
   and unexpected. Expected, perhaps, the pictured rays of light -- called
   [4]crepuscular rays -- originate from [5]the Sun. Unexpected, though,
   [6]the Sun was being [7]partially eclipsed by [8]the Moon at the time
   -- late last month. Expected, perhaps, the [9]Sun's rays are quite
   bright as they shine through gaps in below-horizon clouds. Unexpected,
   though, the [10]crepuscular rays are quite red, likely the [11]result
   an abundance of [12]aerosols in [13]Earth's atmosphere scattering away
   much of the blue light. Expected, with hope, a [14]memorable scene
   featuring both the [15]Moon and the Sun, superposed. Unfortunately,
   from [16]this location -- in [17]Uruguay looking toward [18]Argentina
   -- clouds obscured the eclipse -- which wasn't completely unexpected.
   However, after packing up to go home, the beauty of bright red
   crepuscular rays emerged -- [19]quite unexpectedly. Oh -- and that
   island on the horizon -- it's [20]really two islands.
