A celestial spectacle is set to grace the night sky tonight (March 13) as a rare ‘blood moon’ makes its appearance. This striking event is the first total lunar eclipse since 2022, offering a breathtaking sight for astronomy enthusiasts and casual stargazers alike.
What is a Blood Moon?
A blood moon occurs during a total lunar eclipse when the Earth aligns perfectly between the Sun and the Moon, blocking direct sunlight. However, rather than disappearing into darkness, the Moon takes on an eerie reddish hue.
Professor Don Pollacco from the University of Warwick’s Astronomy and Astrophysics Group explains: “The Moon doesn’t emit its own light but rather reflects sunlight. When the Earth’s shadow covers the Moon, sunlight still reaches it but only after passing through our atmosphere. The atmosphere scatters shorter blue wavelengths while allowing the redder wavelengths to pass through, giving the Moon its characteristic crimson glow.”
When and Where to See It
For those in the United States, the blood moon will start to become visible just before midnight Eastern Time, with the full eclipse peaking around 1 AM ET and lasting into the early hours of March 14.
In the UK, the event will be partially visible. Those in the western regions may catch the total eclipse just before dawn, around 4 AM GMT, when the Moon is low in the western sky. Elsewhere in the UK, although the eclipse won’t be total, it will still provide an impressive view. The best window to observe it is between 5 AM and sunrise before the sky becomes too bright.

Why the Red Color?
The richness of the red shade is influenced by the state of the atmosphere. Dust and particles in the Earth’s atmosphere can influence how much red light reaches the Moon. A deep red or coppery tone suggests significant atmospheric particles, while a lighter shade indicates a clearer atmosphere.
Pollacco describes, “As sunlight moves through our atmosphere toward the Moon, the red wavelengths penetrate with little obstruction, whereas the blue wavelengths are dispersed by dust suspended in the Earth’s atmosphere. The red light reaches the Moon and is then reflected back to us, giving it its distinctive color.”
Interestingly, scientists can use lunar eclipses to study Earth’s atmosphere. By analyzing the way light filters through, researchers can gain insight into the composition of the atmosphere, including pollution levels and the presence of aerosols.
How to Watch the Blood Moon
You won’t need any special equipment to witness this celestial event—just a clear sky and a good vantage point. However, using binoculars or a telescope can enhance the details of the Moon’s surface during the eclipse.
For the best viewing experience:
- Find a location with minimal light pollution, such as a park or countryside area.
- Check the weather forecast to ensure clear skies.
- Give your eyes time to adjust to the darkness for better visibility.
- Consider taking photographs using a camera with manual exposure settings to capture the Moon’s red glow.
Historical and Cultural Significance
Throughout history, blood moons have been surrounded by myths and legends. Many ancient cultures saw them as omens of change, war, or disaster. In some traditions, a blood moon was thought to signal the end of an era or the beginning of something new.
Modern interpretations of blood moons often take on a spiritual or symbolic meaning. Some people believe they bring heightened energy or significant personal transformation. While these ideas remain speculative, one thing is certain: a total lunar eclipse remains one of the most captivating celestial events in the night sky.
