A blood moon takes place when the Earth positions itself directly between the Sun and the Moon.
Instead of turning dark, the Moon glows red due to a phenomenon called Rayleigh scattering.
In this process, shorter wavelengths of light like blue are filtered out, while longer red wavelengths pass through Earth’s atmosphere and reach the Moon, giving it a reddish hue.
During the phase of totality, the Moon moves entirely into the Earth’s darkest shadow, known as the umbra.
The inner dark shadow of the earth is called the umbra, and the faint outer shadow is the penumbra.
At this stage, the Moon takes on a striking red-orange shade, which is why the event is popularly known as a "blood moon."
Depending on the atmosphere and surrounding conditions like dust, pollution, or cloud cover, the Moon may also appear orange or copper in color.
The upcoming eclipse is notable because it is the first total lunar eclipse in nearly three years, with the last one seen in 2022.
