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.

An Eclipse Tree

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 .
