On August 21, 2017, a total solar eclipse will cross the United States allowing millions of people to watch it in person. Tennessee is one of the states that the eclipse will cross!
A total solar eclipse is a cosmic coincidence. When the moon passes in front of the sun and blocks it completely, it casts a shadow onto our planet that plunges areas into a darkness that feels like the nighttime in mid-day. Earth is the only planet in our solar system with a moon the proper size and distance to cause the striking solar eclipses we see.
NASA has created a website where you can find out more about the eclipse, its path and watch live broadcasts. On the day of the eclipse, remember that looking directly at the sun is unsafe except during "totality", when the moon entirely blocks the sun. NASA has a list of approved solar filters and viewers on their website. You can find them, along with other safety tips, at: www.eclipse2017.nasa.gov.
This is a great time to teach children about science and astronomy! NASA's website also includes lots of activities and educational resources about the science behind the eclipse.
