On August 21, the USA will play host to the most spectacular natural phenomenon that a person can witness: a total solar eclipse, when the sun is completely blocked by the light of the moon.
People in Ohio will experience only a partial eclipse, and, without optical aid, will likely not notice much of a difference. People who visit the path of Totality, where the sun is briefly blocked by the moon, will experience day turn to night.
The closest point to the John Glenn Astronomy Park is southern Kentucky. Be sure to plan ahead, as many others will undoubtedly be making the trek to see this astounding, and fairly rare, event!
