Solar Eclipses are seen when light from the sun destined to the Earth
is blocked out by the moon! The diagram shows how the moon casts a shadow
on the only part of the Earth during an eclipse. While one part of the world
sees a total eclipse, the rest of the world will only see a partial eclipse!
During a total eclipse, the Sun's corona is visible!
In a partial eclipse (viewed through a special solar filter)
you can see part of the sun, and the moon only casts part of it's shadow.
A SAFE way to look at an partial eclipse:
You should NEVER look at the sun. Especially with binoculars or a telescope
that aren't equipped with a special darkening filter. Instead, during an
eclipse, you can make an simple device to watch the path of the moon's shadow!
Here are the steps for your Eclipse Viewer:
- Materials: Black contstruction paper, white construction paper
- Punch a hole in the middle of the black costruction paper. You can
do this either with a hole-punch or a thumb tack.
- Put your piece of white construction paper on the ground and hold the
black paper about 12 inches above it so that you can see a single dot of
sunlight on the white paper.
- As the moon moves between the sun and the Earth, a crecent shadow will
cross the light on the white paper.
- Remember, do not look at the sun.. you can see the entire eclipse on
the piece of paper in front of you!
