August 21st is the date of “the Great American Eclipse”, and the hype around it is already starting to reach a fever pitch. It is being called “the Great American Eclipse” because this will be the first total solar eclipse ever that is only visible in the United States. In other words, since the United States became a nation there has never been a total eclipse that was only visible here and nowhere else. And this will be the first total solar eclipse to cross from the west coast to the east coast in 99 years. So for those that love astronomy, this is bigger than the Super Bowl.
