What is a total lunar eclipse?
A total lunar eclipse occurs when the Sun, Earth and the full Moon are perfectly aligned with each other.
This phenomenon results in the Moon entering Earth’s umbra — the planet’s inner, more defined shadow.
The most famous kind of lunar eclipse, a total lunar eclipse often called a Blood Moon by astrologers.
The Moon turns an eerie crimson colour because the only light on the lunar surface is filtered by Earth’s atmosphere.
The particles are extremely effective at scattering blue light, but not so able at scattering red light.
