Explanation:
If you look closely at the shadow of this tree,
you will see something quite unusual: it is
composed of hundreds of images of a
partially eclipsed Sun.
Early today, trees across
North America will be casting similar shadows
as a partial eclipse of the Sun takes place.
In a partial
eclipse, the
Moon does not cover the entire
Sun.
The above effect is created by small spaces
between leaves and branches acting as
pinhole lenses.
Looking at shadows involving eclipse light is
relatively safe - looking directly at the
Sun, even during an eclipse,
is dangerous and
proper precautions should be taken.
The above picture was taken in 1994 on the campus of
Northwestern University.
