Rayleigh scattering
On March 14, 2025, the Moon plunged completely into Earth’s umbra, creating a total lunar eclipse. This phenomenon, known as a "Blood Moon," occurs when the Sun, Earth, and Moon align perfectly, casting our planet’s shadow onto the lunar surface.
The reddish hue arises from Rayleigh scattering: Earth’s atmosphere filters sunlight, absorbing blue wavelengths and bending red ones toward the Moon. The effect mirrors the colors of a sunset but magnified on a planetary scale.
