How is the blood moon caused?

A blood moon, otherwise known as a penumbral lunar eclipse, is a rare astronomical event.

Blood moons occur when the Earth sits between the moon and the sun, rather than the moon between the Earth and sun during a lunar eclipse.

The moon seems red as a result of a phenomenon named ‘rayleigh scattering’ which sees the sun’s rays refracted through the earth’s atmosphere, producing a red moon.
