On August 21, a solar eclipse will be visible from the entire continental U.S.
A solar eclipse is when the moon moves directly between the earth and the sun, blocking the sun from view. Some parts of the country will experience a total eclipse, where the entire sun is covered, while others will only experience a partial eclipse. Total eclipses only last for about two minutes, but partial eclipses can last for hours.
Total solar eclipses are rare. The last one that was visible from the continental U.S. happened in 1979. Solar eclipses that are only visible from the U.S. are even less common, with the last one happening in 1776.
Americans all across the continent will have a chance to see the eclipse, but only those in Oregon, Idaho, Wyoming, Nebraska, Missouri, Kentucky, Tennessee, Georgia, North Carolina, and South Carolina will be able to see a total eclipse.
