Monday, August 21, 2017, will mark the first time in nearly 40 years a total solar eclipse will be visible from the continental United States. Over the course of 100 minutes, 14 states across the country will experience total darkness in the middle of the day as the moon's orbit blocks light from the sun.
The moon will cast a 70-mile wide shadow across the affected areas of the U.S. Other areas of the country will see a partial blocking of the sun.
If you happen to miss today's astrological event, you won't have to wait too long for the next solar eclipse. It's expected to occur on April 8, 2024.
Here are the last five solar eclipses.
February 26, 1979
March 7, 1970
October, 2 1959
June 30, 1954
