                           Astronomy Picture of the Day   
      
       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.

      Explanation: Our Moon doesn't really look like this. Earth's Moon,   
      Luna, doesn't naturally show this rich texture, and its colors are more   
      subtle. But this digital creation is based on reality. The featured   
      image is a composite of multiple images and enhanced to bring up real   
      surface features. The enhancements, for example, show more clearly   
      craters that illustrate the tremendous bombardment our Moon has been   
      through during its 4.6-billion-year history. The dark areas, called   
      maria, have fewer craters and were once seas of molten lava.   
      Additionally, the image colors, although based on the moon's real   
      composition, are changed and exaggerated. Here, a blue hue indicates a   
      region that is iron rich, while orange indicates a slight excess of   
      aluminum. Although the Moon has shown the same side to the Earth for   
      billions of years, modern technology is allowing humanity to learn much   
      more about it -- and how it affects the Earth.
