About the Total Eclipse

On Monday, August 21, 2017 all North Americans will have the opportunity to see the first solar eclipse since 1972. A solar eclipse is when the moon passes between the sun and Earth and blocks all or some parts of the sun. Everyone in North America, and some parts of South America, Africa, and Europe will see a partial solar eclipse. Anyone within the path of totality, when the moon completely covers the sun and the sun’s tenuous atmosphere, will see a total solar eclipse.

The path of totality will cross the United States from West to East coast and its approximately 70 miles wide. Over a few hours, the eclipse will cross through Oregon, Idaho, Wyoming, Montana, Nebraska, Iowa, Kansas, Missouri, Illinois, Kentucky, Tennessee, Georgia, and North and South Carolina. Times for partial and total solar eclipses depend on location.

It’s never safe to look at the sun’s ray, but there are several ways to safely view an eclipse without severely hurting your eyes. Special-purpose solar filters (eclipse glasses) or had-held solar view are best when directly looking at the uneclipsed or partially eclipsed sun.

Challenger Learning Centers across the nation will be celebrating the eclipse with a range of events. Those within the path of totality will be hosting viewing events with approved safety goggles and others will be hosting lectures and activities to help inform citizens about the astronomical phenomena.

What is an Eclipse?

Whether solar or lunar, eclipses happen because of the periodic alignments of the sun, Earth, and moon. These heavenly bodies orbit in space in predictable paths, making it easy for scientist and astronomers to predict their motions. Read more.

Safety 101 – Part 2

In the first Saftey 101 blog, we shared details about the importance of viewing the solar eclipse safely, and as the eclipse covers most of North America, on Monday August 21, we want to make sure viewers know exactly how to view this rare phenomenon. Read more.
