Lunar Eclipse

The video tutorial explains the concept of a lunar eclipse, where the moon darkens as it passes into the Earth's shadow. It covers the roles of the penumbra and umbra, the partially and fully shaded regions of the shadow, respectively. The tutorial details the seven stages of a lunar eclipse, from the initial penumbral contact to the final stage where the moon exits the penumbra. The video emphasizes understanding the shadow dynamics and the visual changes during the eclipse, such as the reddish color during the maximum eclipse.
