NASA | Understanding Lunar Eclipses

The video explains lunar eclipses, which occur when the moon passes through Earth's shadow. Despite the moon's monthly orbit, eclipses don't happen twice a month due to the moon's tilted orbit. Eclipses occur when the moon's orbit aligns with Earth's shadow, causing the moon to appear red due to sunlight scattering through Earth's atmosphere. The video also describes the experience of watching a lunar eclipse.
