"Super relative wolf moon" in January will be the last total lunar eclipse by 2021 – here's how to catch it



  • The total lunar eclipse will occur on January 20.

  • This "super blood moon wolf" gets its name because eclipse will occur when the moon is full (called the wolf moon in January) and closer to Earth than normal (super moon). The shadow of the Earth will make it look reddish.

  • The lunar eclipse is to last an hour and two minutes.


January 20 Earth will pass between the sun and the moon, block the light from the sun and cast a shadow on the moon.

It is a total lunar eclipse and it will be the last one that we observe until May 2021 (Although the lunar eclipses will be earlier).

The total eclipse of the moon is not uncommon – the latter took place in July 2018 – but this one stands out as the "moon of free wolf's blood".

This name is based on the time and place of the moon in relation to the Earth. The total lunar eclipse makes the moon look orange-red due to the effects of the Earth's atmosphere on sunlight that passes through it, which is why it is often called the moon of blood. The full moons, which occur in January, are called "moons of the wolf" (each month has its own name in the full moon), and this seems particularly bright and large, because the moon will be a little closer to the Earth than usual – hence the label "super."

The total lunar eclipse will be fully visible to people in North America, South America, Greenland, Iceland, Western Europe and Africa. People in other parts of the world will see a partial eclipse.

According to NASA, a total lunar eclipse will last an hour and two minutes. For those on the East Coast of the United States, the total eclipse will start around 11:41 pm. local time at peak at 12:16

During the lunar eclipse, the first one touches the outer shadow of the Earth, called the penumbra, and then moves to a full shade called a umber. Then he returns to the penumbra.

About 80% of the Earth's atmosphere is nitrogen gas, the rest is mainly oxygen. After our atmosphere takes on white sunlight, this mixture of gases disperses around the blue and purple colors, which is why the sky seems blue to our eyes during the day.

During the lunar eclipse, Earth's atmosphere disperses blue light and refracts red – a process similar to what we see during sunrise and sunset. That's why the moon turns red when it's in the earth's umber.

Observing the total lunar eclipse is not dangerous – unlike looking at a solar eclipse without protection – so you do not need special glasses.
