For the first time in 99 years, a total solar eclipse will be witnessed. “The Great American Eclipse” will cast a shadow over the entire country, moving diagonally from Oregon in the northwest to South Carolina in the southeast.
A solar eclipse is when the moon completely covers the sun, but this one is special because it is taking place across the entire United States.
“Viewers around the world will be provided a wealth of images captured before, during, and after the eclipse by 11 spacecraft, at least three NASA aircraft, more than 50 high-altitude balloons, and the astronauts aboard the International Space Station – each offering a unique vantage point for the celestial event.”NASA
This is the first eclipse to pass over the United States in the 21st century.
It is the first total eclipse on American soil since 1991, when one was visible from the Big Island of Hawaii.
These total eclipses happen every 12 to 18 months somewhere in the world, often over the open ocean since most of the Earth is covered by water.
The time would vary depending on your location.
“Over the course of 100 minutes, 14 states across the United States will experience more than two minutes of darkness in the middle of the day. Additionally, a partial eclipse will be viewable across all of North America. The eclipse will provide a unique opportunity to study the sun, Earth, moon and their interaction because of the eclipse’s long path over land coast to coast. Scientists will be able to take ground-based and airborne observations over a period of an hour and a half to complement the wealth of data and images provided by space assets.”NASA
As NASA points out, people should not look directly at the sun’s ray during the course of the celestial event. NASA’s advice is that even those viewing the partial solar eclipse need to wear the special eclipse glasses at all times.
