Great American Eclipse 2017
This Doodle’s Key Themes
Skywatchers on the American continent today are in for a special astronomical treat: front row seats to a total solar eclipse. An eclipse occurs when the moon passes between the sun and the earth, blocking the light of the sun from reaching us.
While eclipses aren’t rare, a total eclipse, when viewers from Earth are at the very center of the moon’s shadow, only happens once every 18 months. To see one requires you to be in just the right place on earth, and a total eclipse in the same location only happens every 375 years on average.

It’s been 99 years since an total eclipse crossed the width the United States. This year, the 65-mile wide path of totality with sweep, sash-like, across the country—entering the map at Oregon and exiting at South Carolina. The once-in-a-lifetime spectacle will attract an estimated 7.4 million people to areas in the path of totality, including so-called eclipse-chasers, who plan for years in advance and travel from far and wide to get a glimpse of the stellar phenomenon.
No matter where you are in the country, if you plan to look at or even toward the sun, be sure to protect your eyes. According to experts, only those in the path of totality are safe to look at the eclipse without protection, and only during totality.
