The video explains the phenomenon of solar eclipses, where the Earth, moon, and sun align, causing the moon to cast a shadow on Earth. It covers three types of eclipses: total, annular, and partial. A total eclipse occurs when the moon completely covers the sun, while an annular eclipse happens when the moon is too far to cover the sun entirely, creating a ring-like appearance. A partial eclipse occurs when only part of the sun is obscured. The video also emphasizes the importance of using protective measures when viewing an eclipse to prevent eye damage.
