是的，但是你的树能做到吗？如果你仔细观察这张特色图片中的地面，你会看到许多昨天日食的图像——这是由一棵树造成的。树叶之间的缝隙就像针孔透镜一样，每个缝隙都能在另一个方向上形成日偏食的小图像。这张照片拍摄于美国德克萨斯州的伯勒森。昨天，美洲各地的人们都有幸看到了日偏食，当时月亮移动到太阳的一部分前面。在地球上狭窄地带的人们看到了日环食，也被称为火环月食，当月亮完全被太阳吞没，阳光在月亮的所有边缘周围流动。回答这个主要问题，你的树不仅可以做到这一点，而且每次可见的日食经过头顶时都会这样做。明年4月8日，一场更深的日全食将横跨北美。相册：选定的日食图像发送到APOD

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. Album: Selected eclipse images sent in to APOD
