On the night of January 20-21, the full moon will bring a total lunar eclipse, which will cause Earth’s satellite to take on an eerie red glow in an effect that’s come to be known as the Blood Moon.
At the same time, the moon will sit at the closest point to Earth in its orbit, when it will appear massive in the night sky.
People in North and South America, a large part of Europe and Africa may get a glimpse of a total lunar eclipse overnight from January 20 to 21, the last such event until 2022.
For those in Europe and Africa, the total eclipse will unfold shortly before sunrise.
For those in North and South America, the eclipse can be viewed at the beginning or in the middle of the night.
The full Moon will be in the Earth’s shadow from 03:34 GMT to 06:51 GMT.
When the eclipse begins, a shadow will move in from the left, as if taking a bite out of the Moon.
The total eclipse will last about an hour, beginning at 0441 GMT according to NASA.
During the eclipse, the Moon will still be visible, but in a shade of red.
That’s why a lunar eclipse is often called a ‘blood Moon.’
The red color is due to the same phenomenon that causes sunsets to appear pink, orange or red.
‘A little bit of sunlight is refracted by the Earth’s atmosphere and reaches the Moon, bending around the edges of the Earth,’ explained Walter Freeman, an assistant teaching professor at Syracuse University’s physics department.
