A spectacular astronomical event will take place in India this Sunday night. A rare total lunar eclipse, also known as the “Blood Moon,” will grace the skies. This will be the longest total lunar eclipse visible in India since 2022. According to astronomers, it will be the first time since July 27, 2018, that the entire country will be able to witness a total lunar eclipse. In addition to India, this eclipse will also be visible in China, parts of Africa, and the eastern coast of Australia.
A lunar eclipse occurs when the Earth comes between the Sun and the Moon, casting a shadow on the lunar surface. The red hue seen during a total lunar eclipse is a result of sunlight being refracted and scattered through the Earth’s atmosphere. This unique phenomenon, known as a Blood Moon, has fascinated stargazers and casual observers alike for centuries.
Timing of the Eclipse
The total lunar eclipse will begin on Sunday, September 7, 2025, at 8:58 PM. The full eclipse will last for 82 minutes, beginning at 11:01 PM and ending at 12:23 AM. The partial phase of the eclipse will start earlier at 9:57 PM and will end at 1:26 AM. The entire event will conclude at 2:25 AM on the same night.
Astronomers have predicted that the next lunar eclipse of this magnitude in India will occur on December 31, 2028. This upcoming event is unique in that it offers a longer duration than typical lunar eclipses, providing ample time for viewers to enjoy the spectacle.
Why Are Lunar Eclipses So Rare?
Divya Oberoi, the Chairperson of the Public Outreach and Education Committee of the Indian Astronomical Society and an Associate Professor at the National Center for Radio Astrophysics, Pune, explained that lunar eclipses are not a regular occurrence. They do not happen every full moon or new moon. This rarity is due to the fact that the Moon’s orbit is tilted by approximately five degrees relative to Earth’s orbit around the Sun. This misalignment prevents the perfect alignment of the Earth, Moon, and Sun necessary for a lunar eclipse.
Can the Eclipse Be Viewed with the Naked Eye?
Unlike solar eclipses, which require special glasses for safe viewing, a total lunar eclipse can be observed with the naked eye. There is no need for any protective gear such as special glasses or filters. Niruj Mohan Ramanujam, the head of the Science, Communication, Public Relations, and Education (SCOPE) section at the Indian Institute of Astrophysics, confirmed that it is safe to watch the eclipse without any specialized equipment. However, if desired, binoculars or telescopes can enhance the viewing experience.
The partial lunar eclipse will begin at 9:57 PM, and viewers can observe the Moon gradually moving into Earth’s shadow. As the event progresses, the Moon will appear to darken and eventually take on its characteristic red hue during the total eclipse phase.
Why is it Called the Blood Moon?
During a total lunar eclipse, the Moon turns red because the only sunlight reaching the Moon is refracted and scattered by Earth’s atmosphere. This scattered light gives the Moon its “blood-red” appearance. As explained by Ryan Milligan, an astronomer at Queen’s University Belfast in Northern Ireland, red light is less scattered than blue light, which is why the Moon appears to glow with a red hue.
This phenomenon is one of the key features of a lunar eclipse and is what gives the event its popular name, the “Blood Moon.” The red color is caused by the same scattering effect that produces colorful sunrises and sunsets on Earth.
Viewing Locations and Timing in India
In India, the total lunar eclipse will be visible across most regions. Cities like Delhi, Mumbai, Kolkata, Bangalore, and Chennai will have a clear view of the event, with the best visibility between 11:01 PM and 12:23 AM. The partial eclipse will start earlier at 9:57 PM, allowing viewers to witness the gradual transition of the Moon as it enters the Earth’s shadow.
For astronomy enthusiasts, this is a prime opportunity to observe the dynamic changes in the Moon’s appearance as it moves through the various phases of the eclipse. The gradual darkening of the Moon is a mesmerizing spectacle for both seasoned observers and first-time viewers.
How to Safely Observe the Eclipse
As mentioned earlier, the total lunar eclipse can be safely viewed with the naked eye. No special equipment is required, though telescopes or binoculars may provide a closer, more detailed view of the event. While the eclipse is safe to watch without protection, using a camera or smartphone with a zoom lens can capture stunning photographs of the event.
For those who want to share the experience with others, a pair of binoculars or a small telescope can be used to enhance the view. However, for casual viewers, simply stepping outside to observe the Moon as it changes color will be enough to appreciate this rare event.
The Scientific Significance of the Blood Moon
Lunar eclipses are important events for astronomers because they offer unique opportunities to study both the Moon and Earth’s atmosphere. The red hue of the Moon during a total eclipse is caused by the scattering of sunlight through Earth’s atmosphere. Scientists can use this phenomenon to study the Earth’s composition and its effects on light transmission.
Additionally, lunar eclipses allow astronomers to observe other celestial phenomena, such as the alignment of stars and planets. This makes the Blood Moon an exciting event for those interested in the science of astronomy.
The Cultural and Historical Significance of the Blood Moon
For centuries, lunar eclipses, particularly Blood Moons, have been a source of intrigue and wonder. Many cultures throughout history have associated lunar eclipses with omens, myths, or divine messages. In ancient times, people viewed eclipses as powerful events that could foretell significant changes.
In modern times, however, eclipses are viewed as natural events that provide opportunities for scientific study and public engagement. They remind us of the vastness of the universe and our connection to celestial bodies. Whether seen as a symbol of change, mystery, or simply a beautiful phenomenon, the Blood Moon continues to capture human imagination.
The total lunar eclipse on Sunday, September 7, 2025, offers an incredible opportunity for people across India to witness one of nature’s most beautiful events. This rare Blood Moon will last for 82 minutes and will be visible in most parts of the country. The event will also be visible in parts of China, Africa, and the eastern coast of Australia.
For those who are fascinated by celestial events, the Blood Moon is a chance to connect with the universe and enjoy the beauty of our natural world. Whether you’re an experienced stargazer or a casual observer, this total lunar eclipse promises to be a memorable experience.
