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.
