Celestial Event
Blood Moon
When Earth's shadow turns the Moon crimson red
What is a Blood Moon?
A blood moon is a total lunar eclipse where the Moon appears red or orange. This happens because Earth's atmosphere scatters blue light and bends red light onto the Moon's surface — the same phenomenon that makes sunsets red.
During totality, Earth passes directly between the Sun and Moon, casting a deep shadow on the lunar surface. Unlike a solar eclipse, it is completely safe to view with the naked eye and can last for several hours.
The deep red hue has inspired cultures worldwide for millennia — a celestial drama written in crimson light.
Science
Why Does the Moon
Turn Red?
Earth Blocks Direct Sunlight
During a total lunar eclipse, Earth moves between the Sun and Moon, blocking direct sunlight from reaching the lunar surface.
Atmosphere Acts as a Lens
Earth's atmosphere bends (refracts) some sunlight around the edges of our planet, directing it toward the Moon.
Blue Light Scatters, Red Passes
Shorter blue wavelengths scatter away via Rayleigh scattering, while longer red and orange wavelengths pass through.
Red Light Illuminates the Moon
This filtered crimson light reaches the Moon, giving it the characteristic blood moon appearance during totality.

Why does the moon turn red during an eclipse?
During a total lunar eclipse, Earth blocks direct sunlight from reaching the Moon. However, Earth's atmosphere acts like a lens, bending (refracting) some sunlight around the edges of our planet. This light passes through Earth's atmosphere, which filters out blue wavelengths and allows red and orange light to pass through, casting a reddish glow on the Moon.
How often do blood moons occur?
Total lunar eclipses (blood moons) occur approximately 2-4 times per year on average, but they are only visible from specific locations on Earth. A given location might see a total lunar eclipse every 2-3 years.
Can I see a blood moon with the naked eye?
Yes! Unlike solar eclipses, lunar eclipses are completely safe to view with the naked eye. No special equipment is needed, though binoculars or a telescope can enhance the viewing experience.
