[2] [3] The term eclipse is most often used to describe either a solar eclipse, when the Moon's shadow crosses the Earth's surface, or a lunar eclipse, when the Moon moves into the Earth's shadow.

Dennis L. Gallagher, PhD, of NASA's Marshall Space Flight Center explains shadow bands and how to increase your chances of seeing them during the eclipse.
This word gained traction in April when the moon passed in front of the sun and cast a shadow, creating a total solar eclipse across a path in 13 states, including Texas, Oklahoma, Missouri ...
A total eclipse occurs on average every 18 months [11] when the dark silhouette of the Moon completely obscures the bright light of the Sun, allowing the much fainter solar corona to be visible. During an eclipse, totality occurs only along a narrow track on the surface of Earth. [12] This narrow track is called the path of totality. [13]
