Imagine you lived decades ago, long before information was readily available on a handheld device. Perhaps even long before televisions or radios.
Imagine at that time your job was that of a fisherman, and you were working far off shore, where the only thing visible in any direction was the straight line marrying the deep indigo blue of the ocean with the pale blue softness of the sky.
Or imagine you were a farmer on the broad expanse of the open plains, and you were working your fields under the calm, blue, cloud-less sky of summer.
Now imagine that as you work, the sky begins to darken, as if clouds were slowly obscuring the sun. But there were no clouds, and the darkness is different than you have experienced before.
Shadows started taking on a strange and alien appearance on the ground. The familiar yet mistimed sounds of dusk resonated all around you. The temperature drops by 15 to 20 degrees.
It is still too bright to look into the sky, but all around you, the sky takes on an eerie feel of nightfall, and the sun almost appears to be extinguishing like a fire running out of fuel.
As you start to be consumed by feelings of confusion and dread, the day suddenly blacks out completely -- with the exception of a beautiful, glowing corona with a solid black center visible where the sun once was located. All around, you see planets and bright stars and life feels completely different.
This unique and stunning profundity that a total solar eclipse brought to generations before is not lost on the fact that we can now predict it. It is what has cause experienced eclipse viewers to say that a total solar eclipse is one of the most spiritual experiences of a lifetime -- and why everyone should see one.
Why The Great American Eclipse Is Unique
- While solar eclipses are not rare -- one happens somewhere on the globe about once every 18 months -- they are typically only viewable by less than 0.5% of earth's surface.
- Only about 26 percent are total eclipses (the others are partial or annular).
- Because of its elliptical orbit, the moon sometimes is too far away from the Earth to block out the sun completely during some total eclipses. This time, the moon is in its closest approach to the Earth, allowing those viewing it in the area of totality to see the solar corona in a black, night sky.
- The eclipse will cover the entirety of the US, from Oregon to South Carolina, and will only be visible in the US (which is why it is being calling "the Great American Eclipse"). The last "American" eclipse was 99 years ago.
- And, if you want to wait around for the next total solar eclipse to pass over you, you could be waiting up to 400 years.
This is why the eclipse of 2017 (August 21, 2017) is an absolutely unique and once in a lifetime event.
