On the 21st of August, 2017 (tomorrow or even today, depending on when you're reading this!), there will be a total solar eclipse that goes across the North American continent!
What is a solar eclipse?A solar eclipse happens when the moon lines up just right in the sky to cast a shadow on the ground during the day. This shadow only lasts a few minutes, and it is not very big, so getting to see one can be a once-in-a-lifetime experience for many of us if we're lucky enough to see one!
What is this "totality" thing I keep hearing about?The "totality" of the eclipse is what happens when you are completely in the moon's shadow. Not everyone will be able to see the totality, or a total solar eclipse. Most of the continent will experience a partial solar eclipse.
It is not safe to look at the eclipse directly without the proper eye protection if the sun is not completely blocked by the moon. During totality, it will change from being bright daylight to almost completely dark within just a few seconds and you'll notice it get noticeably colder outside (and it might even get quieter too!). Totality only lasts a few minutes or less, depending on where you are in the moon's shadow.
Where can I see it?A partial eclipse will be visible around morning and on into the early afternoon across a large portion of the North American continent. This includes the southern parts of Canada, the entire continental United States (that's all states except Alaska and Hawaii!), and northern parts of Mexico.
If you're in these specific states in the US, you may have a chance to experience a total solar eclipse (in order of when it will happen): Oregon, Idaho, Wyoming, Nebraska, Kansas, Missouri, Illinois, Kentucky, Tennessee, Georgia, and South Carolina
If you aren't in those states mentioned above, but you're close to them, you still have a chance to experience a near-total solar eclipse where almost all the light will be blocked. Remember:
It is not safe to look directly at the sun without proper eye protection if you are
not completely covered by the moon's shadow!
Proper eye protection?Proper eye protection means special glasses that filter out the sun's bright light.
They are not normal sunglasses, and many of them will look sort of like those cardboard 3D glasses you've seen around. Proper solar glasses will be completely dark, letting almost no light through.
Proper eye protection, such as solar glasses, is important! This is because looking at the sun at any time without proper protection is very bad for your eyes and can cause you to go blind! (Seriously!)
Normal sunglasses do not offer enough protection to keep your eyes safe when looking directly at the sun.
This means it is important to remember
not to try peeking out from behind the safety of your solar glasses to look at the sun directly if it is not completely covered by the moon, because even that is dangerous!
What if I don't live in an area that will experience this solar eclipse?If you don't live in an area that will experience this solar eclipse, or if you're in an area that will only experience a partial one, NASA, the National Aeronautics and Space Administration, will be hosting a live streaming event of it as it takes place on their website.
