On Monday, August 21, 2017 -- a historic total solar eclipse will occur across part of the United States for the first time in nearly 40 years, specifically stretching from Oregon to South Carolina for a very short period of time.
To explain what this rare astronomical event is, the National Geographic has released an informative video that describes what an eclipse is, how solar eclipses happen, the four types of eclipses, and how to view the sun safely if you're within the path of totality.
If you won't be able to witness this upcoming event in person, CNN and Volvo have teamed up for an exclusive live stream of the solar eclipse in 360° virtual reality which starts at 1 p.m. ET on Monday, August 21, 2017.
