                           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.

      A driveway is shown with a car at the top of the frame but a series of   
         shadows across the rest of the frame. A close inspection of these   
         shadows shows that they are frequently small images of an ongoing   
        partial solar eclipse. Please see the explanation for more detailed   
                                   information.

      Explanation: Yes, but can your tree do this? If you look closely at the   
      ground in the featured image, you will see many images of yesterday's   
      solar eclipse -- created by a tree. Gaps between tree leaves act like   
      pinhole lenses and each create a small image of the partially eclipsed   
      Sun visible in the other direction. The image was taken in Burleson,   
      Texas, USA. Yesterday, people across the Americas were treated to a   
      partial eclipse of the Sun, when the Moon moves in front of part of the   
      Sun. People in a narrow band of Earth were treated to an annular   
      eclipse, also called a ring-of-fire eclipse, when the Moon becomes   
      completely engulfed by the Sun and sunlight streams around all of the   
      Moon's edges. In answer to the lede question, your tree not only can do   
      this, but will do it every time that a visible solar eclipse passes   
      overhead. Next April 8, a deeper, total solar eclipse will move across   
      North America.
