This astronomical event is a must-see, but see it safely
Unless you’ve been under a rock, you know that August 21 is the date of a total solar eclipse, the first mainland America has seen in yearly 40 years. During this historic event, the sun, which is 400 times larger than the moon, will cross pass with the moon which is 400 times farther away from the earth then the moon. During this time, the sun appears to be blocked out by the moon, except for its blinding halo formed by the sun’s gaseous atmosphere that shines around the moon’s silhouette. This will be something you and your children will want to see and experience, but viewing it must be done carefully so that the sun’s rays do not damage the naked eye.
Anytime you stare into the sun you can damage your eyes. This can happen in as little as 30 seconds. The reason an eclipse is more dangerous to the eye is because it causes people to look directly into the sun and for extended periods of time. The only time it’s safe to look directly at the eclipse is during the 1 or 2 minutes that the moon completely blocks the sun, and only people watching from a narrow band from Oregon to South Carolina—known as the path of totality—will witness that.
If you’d like to view this fascinating spectacle, make sure that you wear proper eyewear or use a viewing device. It is not advised to even use a camera or other lenses, as the rays can damage lenses and filters; and it is definitely not recommended to look through any sort of lens, binoculars or telescope. The best advice is to wait until after the event and view images in media taken by professionals using the proper equipment.
It is not safe to use regular sunglasses to watch an eclipse, though inexpensive eclipse glasses I readily available online and it many retailers for the price of about $5 to $10. Make sure to purchase your glasses from a reputable source, as several brands of these glasses on Amazon were recalled due to safety issues. Check out companies approved by the AAS Solar Eclipse task force.
If you have not purchased your glasses yet, you may be out of luck, because most vendors are sold out. But you can still make a pinhole viewer. Using this method, you pass the sunlight
