During a solar eclipse, it is very important to protect your eyes. For hundreds of years, astronomers have used different methods to observe the Sun safely. One of them, the eclipse projector, allows you to view a small image of the Sun through a closed box. You will see the Moon taking "bites" out of the Sun!

VERY IMPORTANT! Looking directly at the Sun, without appropriate protection, can lead to serious problems such as partial or complete loss of eyesight.
