This crossword puzzle is about solar eclipses, lunar eclipses, partial eclipse, annular eclipse, a total solar eclipse, etc.
A partial eclipse is the most common eclipse. This eclipse looks as if the moon was taking a medium sized bite out of the sun. This eclipse was building up to a a total solar eclipse or an annular solar eclipse, but can only be seen as a partial eclipse. That is because of where you are looking at it from earth. Most of North America will be able to see this eclipse. Although if you are located in the path of totality, you would be able to see the annular eclipse. An annular eclipse is the second to rarest eclipse. This eclipse is only visible in the path of totality. This eclipse is commonly referred to "the ring in the sky". The last and most rare eclipse out of the three is called the total solar eclipse. This is the eclipse that will be happening on August 21, but again only visible to the path of totality. The other chunks of North America will be watching the partial eclipse, (which I talked about earlier), and again this is because of the location.
The path of totality in a solar eclipse is basically where the sun and moon travel together from the West coast to the East coast. This site shares a video on how exactly it will move from Depoe Bay Oregon, to Charleston South Carolina. The other cities and states are listed on the map, which are Grand Teton N.P WY, Casper WY, N. Platte NE, Lincon NE, Columbia MO, Carbondale, IL, Nashville TN, Cungmans Dome, NC, and last but not least Charleston SC.
In this game/slideshow, it shows that during a solar eclipse, the sun is 93 million miles from earth, (145 million km) while the moon is 239 thousand miles, (384 thousand km). The sun is 93 million miles from the moon, (145 million km).
Why do you need to wear those weird eclipse glasses? Because staring into the sun, even the most concealed or covered sun, can create blind spots in only a few seconds. Although, it can take days, weeks even years to actually show the blind spots.
