The lunar eclipse, also known as “Chand Grahan” in Pakistan, is a celestial event that occurs when the Moon passes through the Earth’s shadow. This results in the Moon appearing reddish or darkened in the night sky, hence the name “blood moon”.
Lunar eclipses have been of great astronomical, cultural, and religious significance throughout history. In Pakistan, lunar eclipses hold a special place in the cultural and religious beliefs of the people. Many communities observe lunar eclipses as significant events and may engage in rituals and customs associated with them.
What is Lunar Eclipse
A lunar eclipse is a natural phenomenon that occurs when the Earth passes between the Sun and the Moon, casting a shadow on the Moon. During a lunar eclipse, the Earth blocks the Sun’s light from reaching the Moon, causing the Moon to appear reddish in color. This is sometimes referred to as a “blood moon.”
Explanation of Lunar Eclipse
A lunar eclipse occurs when the Moon passes through the Earth’s shadow. This can only happen during a full moon, when the Sun, Earth, and Moon are aligned in a straight line.
There are three types of lunar eclipses: total, partial, and penumbral. During a total lunar eclipse, the Moon is fully immersed in the Earth’s shadow, causing it to take on a reddish hue and appear to be “blood moon.” This reddish color is due to the sunlight that passes through the Earth’s atmosphere and is bent towards the Moon.
A partial lunar eclipse occurs when only a portion of the Moon enters the Earth’s shadow, while a penumbral lunar eclipse occurs when the Moon passes through the Earth’s penumbral shadow, causing a slight darkening of the Moon’s surface.
The timing and duration of a lunar eclipse can vary, depending on the Moon’s position in its orbit and the relative positions of the Sun, Earth, and Moon. Lunar eclipses can last from a few hours to several hours.

Causes of Lunar Eclipse
A lunar eclipse occurs when the Moon passes through the Earth’s shadow. This can only happen when the Sun, Earth, and Moon are aligned in a straight line. The following are the causes of a lunar eclipse:
- Alignment of Sun, Earth, and Moon: A lunar eclipse can only occur when the Sun, Earth, and Moon are perfectly aligned, with the Earth in the middle. This alignment causes the Earth’s shadow to fall on the Moon.
- Earth’s shadow: During a lunar eclipse, the Earth casts a shadow on the Moon, blocking the Sun’s light from reaching the Moon. This is because the Earth is much larger than the Moon and its shadow is much wider.
- Shape of Earth’s shadow: The Earth’s shadow is not a solid block, but instead is divided into two parts – the umbra and the penumbra. The umbra is the dark central portion of the shadow, while the penumbra is the lighter outer portion.
- Moon’s position in its orbit: The timing and duration of a lunar eclipse depend on the Moon’s position in its orbit relative to the Earth and Sun. If the Moon is near its closest point to the Earth (perigee), it will spend more time in the Earth’s shadow, resulting in a longer lunar eclipse.
- Earth’s atmosphere: The Earth’s atmosphere bends the Sun’s light, causing the light to reach the Moon even when it is in the Earth’s shadow. This bending of light is what gives the Moon a reddish hue during a total lunar eclipse.
Types of Lunar Eclipse
There are three main types of lunar eclipses: total, partial, and penumbral.
- Total Lunar Eclipse: During a total lunar eclipse, the Moon is completely covered by the Earth’s umbral shadow, causing the Moon to appear reddish in color. This reddish color is due to the bending of sunlight by the Earth’s atmosphere. Total lunar eclipses can last for several hours and are the most dramatic type of lunar eclipse.
- Partial Lunar Eclipse: A partial lunar eclipse occurs when only a portion of the Moon enters the Earth’s umbral shadow. During this type of eclipse, only a section of the Moon will appear reddish, while the rest of the Moon remains lit by the Sun.
- Penumbral Lunar Eclipse: A penumbral lunar eclipse occurs when the Moon passes through the Earth’s penumbral shadow, causing a slight darkening of the Moon’s surface. This type of eclipse is much less noticeable than a total or partial lunar eclipse and can be difficult to observe with the naked eye.
Occurrence of Lunar Eclipse in Pakistan
Lunar eclipses occur when the Earth passes between the Sun and the Moon, casting a shadow on the Moon. Lunar eclipses are visible from any location on the night side of the Earth, provided that the Moon is above the horizon.
