When you look at the sky and sniff the stars, the only thing that constantly arouses curiosity is the moon, a huge mass of rock that glows in the sun’s rays. Get ready now to experience one of the most beautiful cosmic phenomena, the total lunar eclipse or the so-called blood moon.

The first total lunar eclipse of 2021 will be visible on May 26th, when the moon passes through the Earth’s shadow. As the astronomical climax of the year 2021, the solar eclipse will be a combination of a full moon, blood moon and total lunar eclipse. The blood moon, which will be visible on May 26th, will be one of the largest of the year.

What is a total lunar eclipse?

A total lunar eclipse occurs when the sun, earth and moon are aligned in one line. During the solar eclipse, the earth is located between the sun and the moon, preventing sun rays from reaching the moon and casting their shadows on the lunar surface.

The earth’s shadow that falls on the moon is divided into three parts: umbra, the darker, central part, penumbra, the outer part of the shadow, and antumbra, the partially shaded area behind the umbra.

During the total lunar eclipse, the earth’s umbra covers the moon. The total lunar eclipse only occurs when the moon is full.

What is blood moon?

While the earth casts its shadow on the moon, it is not completely invisible and can be seen with the naked eye when the earth’s atmosphere bends the sunlight and indirectly illuminates the lunar surface. Due to the refraction of sunlight, the colors with shorter wavelengths are scattered and filtered, while the colors with higher wavelengths such as orange and red illuminate the surface of the moon, giving it a red-orange glow. This red and orange moon is known as the blood moon.

Aside from Blood Moon, the total lunar eclipse can also be orange or brown, depending on dust particles and different wavelength colors reaching the lunar surface.

How is it going to happen?

The event begins when the moon enters the outer shadow penumbra of the earth and slowly moves into the umber (inner shadow) of the earth and turns red, a state of partial lunar eclipse. When the moon penetrates the umber, a total lunar eclipse occurs. The total lunar eclipse will last for 14 minutes and 30 seconds on May 26th. After the eclipse, the entire event repeats itself in reverse order when the moon moves out of the shadow of the earth.
