The Universe: The Lunar Eclipse

The video explains the phenomenon of a lunar eclipse, where the Earth blocks sunlight from reaching the moon, causing it to appear red. It occurs when the Earth is aligned between the sun and the moon. The lunar eclipse can be observed without protective glasses and happens twice a year during the full moon phase. The moon's color gradually changes to red and returns to normal within a couple of hours.
