WASHINGTON, Aug. 22 (UPI) -- Mark your calendars for Aug. 21, 2017. That's when all of North America will get a once-in-a-lifetime glimpse at a total solar eclipse.
The Great American Eclipse, as its been dubbed, will be visible to millions across the United States for the first time in nearly four decades. It will mark the first time this century a total solar eclipse will cross through the contiguous United States. It's also the first time the shadow track, called the path of totality, will sweep across the U.S. and no other country. About 200 million people will be able to reach the path of the eclipse, which will sweep the nation from South Carolina to Oregon, within a one-day drive.
