A partial solar eclipse with a crescent sun against a red background and windmills in the foreground
  • A total solar eclipse is a feast for the eyes, but don't forget to look around. 
  • There's more to see during a total solar eclipse than just the moon itself. 
  • Solar flares, a brilliant corona, 2 planets, and a diamond ring are just some of what to look for. 

When a total solar eclipse passes over the United States on Monday, more than 31 million Americans living in the path of totality, where the moon will completely obscure the sun, can witness a series of rare phenomena that many won't see in their hometowns again for hundreds of years.
