Did you know that today is the last time you’ll be able to see the Transit of Venus this century? In fact, it will be the last time you’ll be able to see it for the next 105 years. The Transit of Venus occurs when the planet Venus passes in front of the sun. Beginning at around 6 PM in New York, you’ll be able to see this unusual event. But don’t look directly at the sun! To view the sun, you can reuse a long cardboard box and some tin foil to make your own pinhole projector in just a few simple steps :
1) Cut a medium sized hole in the center of one end of the box or tube.
2) Tape a piece of foil over the hole.
3) Using a pin, poke a hole in the foil.
4) At the other end of the box or tube, cut a rectangular viewing hole.
5) Tape a piece of white paper on the inside of this end of the box.
After you have assembled your pinhole projector, aim it directly at the sun until you see a round image of the sun projecting onto the white paper inside. When the Transit of Venus occurs, you will see a small black dot travel in an arc across the sun. Unless you plan on being around in 2117, make sure that you don’t miss this rare phenomenon!
