On August 21, 2017, the sun's shadow will sweep across North America as millions revel in a rare total solar eclipse, NBC News reported.
It's the first one to grace the continental United States since 1979 and the first to run from sea to shining sea since 1918.
The roughly 75-mile strip of darkness will race from southwest Oregon to South Carolina at about 1,700 mph, bringing a sudden drop in temperature drop and the sight of the sun's seldom-seen corona.

The day's top national and international news.
