•
The "blood moon" effect is caused by the Earth’s atmosphere scattering sunlight, projecting a reddish color onto the moon.
Why This Matters: Lunar eclipses are not only visually stunning but also provide valuable opportunities for scientific study and public engagement with astronomy. This event connects people across different continents through a shared experience of observing the cosmos.
In-Depth Analysis
The September 2025 total lunar eclipse captivated skywatchers with its dramatic transformation of the moon into a blood-red orb. This phenomenon occurs because, during a total lunar eclipse, the Earth passes between the sun and the moon, casting a shadow on the lunar surface. However, some sunlight still reaches the moon indirectly.
As sunlight passes through Earth’s atmosphere, shorter wavelengths (blues and greens) are scattered away, while longer wavelengths (reds and oranges) are refracted and bent towards the moon. This effect is similar to why sunsets appear red. The result is that the moon takes on a reddish or coppery hue, often referred to as a "blood moon."
For viewers in Asia and Western Australia, the entire eclipse was visible, offering a complete sequence of the moon entering Earth’s shadow, reaching totality, and then gradually emerging. In Europe and Africa, the moon rose while already in the midst of totality, providing a dramatic start to the viewing experience. Observers were encouraged to find locations with clear views of the horizon to maximize their enjoyment of the event.
