Understanding the duration and mechanics of this remarkable phenomenon is key to fully appreciating its transient magic. In this article, we delve into the question that sparks curiosity in the minds of stargazers: How long does a blood moon last?
During a total lunar eclipse, the sun, Earth, and the moon align in a straight line, with Earth positioned perfectly between the two. As the moon enters Earth’s shadow, it undergoes a fascinating transformation. Instead of being engulfed in complete darkness, the moon takes on an ethereal glow, thanks to atmospheric refraction. This bending of sunlight around Earth’s atmosphere causes the shorter-wavelength blue and green light to scatter, leaving behind predominantly reddish hues. The result is a breathtaking sight that has inspired wonder and awe for centuries. Yet, the duration of a blood moon is not constant, and it varies depending on several factors. In the following sections, we explore the factors that influence the length of a blood moon and unravel the secrets behind this celestial marvel.
What causes a blood moon?
A. Earth’s position in relation to the sun and moon
A blood moon occurs during a lunar eclipse, which happens when the Earth passes between the sun and the moon, casting a shadow on the moon’s surface. The positioning of the Earth, sun, and moon is crucial for a blood moon to occur.
B. Refraction of sunlight through Earth’s atmosphere
During a blood moon, the moon appears to have a reddish hue. This is caused by the refraction of sunlight through the Earth’s atmosphere. When sunlight passes through the Earth’s atmosphere, the shorter blue and green wavelengths scatter, while the longer red wavelengths continue on a straight path, resulting in a red hue on the moon’s surface. This phenomenon is similar to how sunlight creates a red or orange sunset.
During a lunar eclipse, the Earth’s atmosphere refracts the sunlight, bending it to reach the moon even when it is in the Earth’s shadow. This gives the moon its distinctive reddish color, hence the name “blood moon.”
Understanding the science behind the blood moon adds to its intriguing nature, making it a fascinating celestial event for both scientists and enthusiasts alike.
It’s important to note that not all lunar eclipses result in a blood moon. The intensity of the reddish color can vary depending on various factors such as the amount of dust particles or pollutants in the Earth’s atmosphere at the time of the eclipse.

Understanding lunar eclipses
A lunar eclipse occurs when the Earth aligns between the Sun and the Moon, causing the Moon to pass through the Earth’s shadow. This alignment creates a remarkable celestial event known as a blood moon.
There are three main types of lunar eclipses:
1. Total lunar eclipse: During a total lunar eclipse, the Earth completely blocks the Sun’s rays from reaching the Moon. As a result, the Moon appears to have a reddish hue, hence the term “blood moon.” This reddish color is caused by the refraction of sunlight through the Earth’s atmosphere. The Earth’s atmosphere acts like a lens, bending the sunlight and filtering out shorter wavelengths, such as blue and green, while allowing longer wavelengths, like red, to pass through. This gives the Moon its distinctive reddish glow during a total lunar eclipse.
2. Partial lunar eclipse: In a partial lunar eclipse, only a portion of the Moon passes through the Earth’s shadow. This causes only a part of the Moon to appear reddish, while the rest remains unaffected.
3. Penumbral lunar eclipse: A penumbral lunar eclipse occurs when the Moon passes through the Earth’s penumbra, the outer part of the shadow where sunlight is only partially blocked. During this type of eclipse, the Moon may appear slightly dimmer but does not exhibit the characteristic reddish hue of a blood moon.
The duration of a blood moon is influenced by various factors. Firstly, the Earth’s atmosphere plays a role in determining how much sunlight is refracted and how vivid the red color appears. The composition and density of particles in the atmosphere can vary, affecting the intensity of the eclipse.
Secondly, the size of the Earth’s shadow also influences the duration of a blood moon. The shadow can be larger or smaller depending on the distance between the Earth and the Moon, as well as the alignment of the three celestial bodies. A larger shadow results in a longer duration for the eclipse.
On average, the duration of a total lunar eclipse, including the blood moon phase, can range from a few minutes to a little over an hour. However, it is important to note that the entire lunar eclipse event, from the beginning of the penumbral phase to the end of the umbral phase, can last several hours.
In conclusion, blood moons are a captivating phenomenon that occurs during lunar eclipses. The specific type of lunar eclipse and the duration of the blood moon phase are influenced by factors such as the Earth’s position in relation to the Sun and Moon, the refraction of sunlight through the Earth’s atmosphere, and the size of the Earth’s shadow.
