Exploring the Mysteries of Eclipses

The video explains the occurrence of solar and lunar eclipses, detailing how the alignment of the sun, moon, and earth causes these phenomena. Solar eclipses happen when the moon blocks the sun's light from reaching the earth, while lunar eclipses occur when the earth blocks sunlight from reaching the moon. The video also discusses why eclipses are rare due to the moon's tilted orbit and the alignment of nodes. It concludes with a teaser about the moon's influence on tides.

What is an eclipse?

• When the Sun's light is reflected by the Moon.

• When the Earth rotates around the Sun.

• When one celestial body moves in front of another, blocking its light.

• When the Moon rotates around the Earth.
