What is a solar eclipse?

During a solar eclipse the the Moon passes between the Sun and Earth and blocks all or part of the Sun.  

This is different from a lunar eclipse, when the Earth blocks most of the sunlight that normally reaches the Moon. In a solar eclipse, the Sun gets darker; in a lunar eclipse, the Moon gets darker.  Visit our lunar eclipse page to learn more.

Watch this NASA video to learn more about the different roles of the Moon in lunar and solar eclipses.

During a total solar eclipse, the Moon lines up perfectly to fully block the Sun; in a partial solar eclipse, the Moon only blocks part of the Sun; and during an annular eclipse, alignment is perfect but the Moon is too far away from the Earth to completely obscure the Sun.

Upcoming eclipses viewable in North America

Two major solar eclipses are coming to North America!
Saturday, October 14, 2023, an annular ("ring of fire") eclipse will be experienced in the US from Oregon to Texas;  all of North America will have at least a partial solar eclipse.
Monday, April 8, 2024, a total solar eclipse will be seen in the US from Texas to Maine in the process; all of North America will have at least a partial solar eclipse.

Where Can You See It?
You can see a partial eclipse, where the Moon covers only a part of the sun, anywhere in North America (see "Who can see it?"). To see a total eclipse, where the moon fully covers the sun for a short few minutes, you must be in the path of totality. In 2024 the path of totality is a relatively thin ribbon, around 70 miles wide, that will cross the U.S. from Southwest to Northeast.  States on the path of totality include: Texas, Oklahoma, Arkansas, Missouri, Illinois, Indiana, Kentucky, Ohio, New York, Vermont, New Hampshire, and Maine.

At-Home Activities and Apps

  • DIY Sun Science App
    DIY Sun Science includes 15 easy-to-use hands-on activities to learn about the Sun and its important relationship with Earth. Learn how to cook in a solar oven, measure the size of the Sun, or explore shadows in model Moon craters! Each activity includes step-by-step instructions that have been tested by educators, kids, and families. Activity materials are easily available and inexpensive. PDF versions of hands-on activities are also available for download in both English and Spanish.

You never want to look directly at the sun without appropriate protection.  That could severely hurt your eyes.  However, there are numerous safe ways to view an eclipse.  

An eclipse is a rare and striking phenomenon you won't want to miss, but you must carefully follow safety procedures. It is vital that you protect your eyes at all times. The only safe way to look directly at the uneclipsed or partially eclipsed Sun is through special-purpose solar filters, such as eclipse glasses or handheld solar viewers. Homemade filters or ordinary sunglasses, even very dark ones, are NOT safe for looking at the Sun.
