Super Blood Moon – 26th May 2021

Super Blood Moon – 26th May 2021

You will be lucky to watch the Super Blood Moon, “most super” of the year’s “super moons” on 26th May 2021.

Total Lunar Eclipse is happening on the 26th of May 2021 when the full moon enters the Earth’s shadow. During this phase the moon will appear bigger and brighter than normal.

When the Moon during its orbiting around earth, is at or near its closest point to earth and when it is a full moon, it is called as a “super moon”. During its orbit around earth, it travels through an elliptical orbit. Each month, the moon passes through the point closest to earth (Perigee) and farthest from earth (Apogee).

If the sky is clear, people all around the world can observe the super moon throughout the night. The Lunar eclipse is sometimes hard to catch depending upon your location. It may last for about 15 minutes and during this time, if the moon is up in your area, you will be able to see it.

Colour change of Moon during Lunar eclipse

Do you know why the colour of moon changes during Lunar eclipse?. Our brain interpret variations in physical properties of light and that is who we are able to see colours. Light while passing through air or atmosphere, different colours behave differently. Sunlight gets bent and scatters while passing through the Earth’s atmosphere. Light gets filtered as it passes through the atmosphere. Red light travels in a straight path through air. Scattering of red light is seen normally only during the sunrise and sunset.

During the Lunar eclipse the heavily filtered morning and evening light makes its way to the Lunar surface traveling through Earth’s atmosphere. The eclipsed moon is dimly illuminated by the red-orange light left over from all of the sunsets and sunrises. If there amount of dust or cloud in earth’s atmosphere is more during eclipse, the moon will appear more reddish.
