Explainer: July 4 Lunar Eclipse

The video tutorial explains the occurrence of a penumbral eclipse over the Americas between July 4th and 5th, as reported by NASA. It describes how penumbral eclipses happen when the moon moves through Earth's lesser shadow, the penumbra. The video also covers the visibility of the eclipse, noting that it will be observable in the Americas and partially in Northwest Africa. Additionally, it explains the difference between a penumbral and a full lunar eclipse, where the latter involves the moon entering Earth's umbra, sometimes resulting in a Blood Moon. The next Blood Moon is expected in 2021.
