What Is a Solar Eclipse?
A solar eclipse occurs when the Moon passes between the Earth and the Sun, temporarily blocking sunlight. In the United States, eclipses can be total, annular, or partial, depending on alignment and viewing location.
Where and When Can You See a Solar Eclipse in the USA?
Solar eclipses cross different parts of the country on a predictable schedule. The path of totality and annularity shifts over time, and NASA publishes detailed maps and dates for upcoming events across the continental United States.
How to Watch Safely
Looking directly at the Sun can cause serious eye damage. Use ISO-certified solar viewers or handheld solar filters during any phase of the eclipse. Remove filters only during totality if you are within the path of total eclipse. NASA offers guidance on safe viewing equipment and practices.
