Eclipses

An eclipse is an astronomical event that occurs when one celestial body moves into the shadow of another celestial body.

The two main types of eclipses are solar eclipses and lunar eclipses.

A solar eclipse occurs when the Moon comes between the Earth and the Sun, blocking the Sun's light.

A lunar eclipse occurs when the Earth comes between the Sun and the Moon, causing the Earth's shadow to fall on the Moon.

A total solar eclipse occurs when the Moon completely covers the Sun, as viewed from Earth.

A partial solar eclipse occurs when only a part of the Sun is obscured by the Moon.

A total lunar eclipse occurs when the entire Moon passes through the Earth's umbra, resulting in a darkened Moon.

A partial lunar eclipse occurs when only a part of the Moon enters the Earth's umbra.

The umbra is the darkest part of a shadow where the light source is completely blocked.

The penumbra is the lighter part of a shadow where the light source is partially blocked.
