Why will Moon turn blood red in September?
Get ready for a celestial spectacle like no other! On the night of September 7-8, the Moon will turn a deep shade of red, a phenomenon known as a total lunar eclipse. This rare event will be a treat for stargazers and astronomers alike, offering a unique opportunity to witness the Moon’s transformation into a “Blood Moon”.
But what causes this eerie red hue? And what can we expect during this event? In this blog post, we’ll delve into the science behind this phenomenon and provide you with all the information you need to know about the upcoming total lunar eclipse.
What is a total lunar eclipse?
A total lunar eclipse occurs when the Earth passes between the Sun and the Moon, casting its shadow on the lunar surface. This can only happen during a full moon, when the Moon is on the opposite side of the Earth from the Sun. The Earth’s shadow has two parts: the umbra, which is the darker inner shadow, and the penumbra, which is the lighter outer shadow.
During a total lunar eclipse, the Moon will first enter the penumbra, causing a subtle darkening of its surface. As it continues to move into the umbra, the Moon will gradually take on a reddish hue, eventually becoming fully immersed in the Earth’s shadow. This is when the Moon appears to turn blood red, a sight that is both breathtaking and awe-inspiring.
Why does the Moon turn red?
The red color of the Moon is caused by a phenomenon called Rayleigh scattering. When sunlight enters Earth’s atmosphere, it encounters tiny molecules of gases such as nitrogen and oxygen. These molecules scatter the shorter, blue wavelengths of light more than the longer, red wavelengths, giving the sky its blue color.
During a total lunar eclipse, the Earth’s atmosphere scatters the blue light in a similar way, but this time it’s the light that has traveled through the Earth’s atmosphere and is reflected off the Moon’s surface. The result is a reddish hue, which is often described as a deep orange or blood-red color.
How long will the eclipse last?
The total lunar eclipse on September 7-8 will last for approximately 82 minutes, making it one of the longest in recent times. The eclipse will begin at 10:55 PM IST, with the Moon entering the Earth’s penumbra. The total phase of the eclipse will start at 1:00 AM IST and will last until 2:22 AM IST.
What can we expect during the eclipse?
During the eclipse, the Moon will take on a reddish hue, gradually deepening in color as it moves further into the Earth’s shadow. The eclipse will be visible from most parts of the world, including India, Africa, Asia, and Europe.
Stargazers can expect the following:
- The Moon will appear to darken and take on a reddish hue as it enters the Earth’s penumbra.
- As the Moon moves further into the Earth’s shadow, the red color will deepen and become more intense.
- The total phase of the eclipse will last for approximately 82 minutes, during which the Moon will be fully immersed in the Earth’s shadow.
- The Moon will then emerge from the Earth’s shadow, gradually returning to its normal white color.
Conclusion
The upcoming total lunar eclipse on September 7-8 is a rare and awe-inspiring event that will offer a unique opportunity to witness the Moon’s transformation into a “Blood Moon”. By understanding the science behind this phenomenon, we can better appreciate the beauty and complexity of our celestial neighbors.
So mark your calendars and get ready to witness this incredible event! Whether you’re an astronomy enthusiast or simply a curious observer, the total lunar eclipse is an experience you won’t want to miss.
