On August 21, the shadow of the moon will pass through the continental US for the first time since 1979. The predicted eclipse path, calculated on the basis of modern astronomical knowledge, is shown on this video from NASA.
For most US residents, a trip to the full eclipse will take about one day. The rest of North America will have a private solar eclipse. In the full eclipse, if the sky is clear enough, the Moon will close the Sun for a maximum period of 2 minutes and 40 seconds, and there will come an ominous darkness.
