The Great American Eclipse

On Monday, Aug. 21, 2017, all of North America will be able to see a solar eclipse, in what many are calling “The Great American Eclipse.” Those within the path of totality, where the moon will completely cover the sun, will get to see a rare total solar eclipse, which hasn’t been seen over the United States since 1979. Those outside the path of totality will still get to experience a partial eclipse. Vox’s handy little tool will let you find out how much of the eclipse you’ll see, and when. All you have to do is enter your zip code. 

A solar eclipse is a natural phenomenon where the Moon passes between Sun and the Earth, and fully or partially blocks out the Sun for a time. While it might make sense to think that it’s safe to look directly at the Sun during an eclipse, it’s still just as dangerous as looking into an unobscured Sun. Check out this site for some safety tips in viewing the 2017 eclipse.

An eclipse has five stages:

  • First Contact (partial eclipse begins)
  • Second Contact (total eclipse begins)
  • Totality and Maximum Eclipse
  • Third Contact (total eclipse ends)
  • Fourth Contact (partial eclipse ends) 

Eclipse history

Eclipses and humans have a long relationship. In some ancient cultures, they were seen as supernatural events or bad omens. According to National Geographic, two court astrologers in ancient China may have been beheaded for failing to anticipate a total eclipse. The ancient Greek historian Herodotus wrote that an eclipse during a battle between the Medes and the Lydians caused both sides to lay down their weapons and declare peace.

The first known telescopic observation of a total solar eclipse was in France in 1706. English astronomer Edmund Halley accurately predicted and observed a solar eclipse in May of 1715, nine years later. As far as eclipses in the U.S., the last time a total eclipse was visible from coast to coast was on June 8, 1918. So whether you can see a total or partial eclipse, get out there and (safely) enjoy it!
