For the first time in 100 years, a solar eclipse will cross the entire United States on August 21, 2017.
The Moon will pass between the Sun and the Earth, and its shadow will sweep across the country. Find out how you can see a solar eclipse and more with the National Air and Space Museum. See you in the shadow!
Your quick guide to everything you need to know about the solar eclipse.
What is a solar eclipse?
A solar eclipse occurs when the Moon passes between the Sun and the Earth, and blocks the bright light of the Sun’s surface from view. The shadow of the Moon will fall in a small path on Earth’s surface, called the zone of totality. Learn more >
How do you view the solar eclipse safely?
In the shadow, during the few minutes of totality, you can view the total solar eclipse without any protection. Anywhere outside that zone, view the partial solar eclipse with safe solar viewers, make a pinhole projection, or add a safe solar filter to your telescope. Learn more >
