In reality the science behind the epic lunar eclipses, that occurs 2-4 times a year, is simple. A lunar eclipse happens when a full Moon passes directly behind the Earth. Therefore the Earth’s shadow blocks most of the sunlight from hitting the moon and gives it a bloody look.
The Earth’s shadow can be divided into two parts: The umbra, which is the dark center shadow and the penumbra which is the outer part, where the sun is only partially blocked. With that being said, the type of eclipse depends on which part of the Earth’s shadow the Moon falls.
Types of lunar eclipses
Total lunar eclipse: It occurs when the Moon fully enters the umbral shadow making it look like a larger super-moon with a unique reddish colour. This type of lunar eclipse is not only known to be the rarest out of all of the eclipses, but it is also the one that we will be seeing tomorrow, Jan 20th.
Partial lunar eclipse: All total lunar eclipses go through a partial phase, but some are solely partial eclipses. This happens when the Earth’s shadow doesn’t fully cover the Moon, making it look like a bitten apple.
Penumbral lunar eclipse: This known to be the least interesting type of eclipse, because not much happens. The Moon is fully in the Earth’s penumbral shadow,which gives it a slight dusky appearance, and is practically unnoticeable.
Overall, this Sunday is a great opportunity for people in B.C. to see the rarest lunar eclipse. I know that I personally will be watching and recording this beautiful event!
