On May 26, people all over the world will witness a supercelestial event when the first lunar eclipse of 2021 occurs. What makes this even more unique is that it will occur simultaneously with a supermoon, a lunar eclipse, and a red blood moon together!
The total lunar eclipse will begin at 4:47:39 a.m. EDT, according to the National Aeronautics and Space Administration (NASA). It will be visible in India at about 2:17 p.m. and will last until 7:19 p.m.
What is a Super Moon?
When a full or new Moon coincides with its closest approach to the Earth, NASA calls it a Super Moon. The "perigee" is the nearest point on the orbit, and the full Moon appears slightly brighter and larger than a usual Moon when it appears at the perigee, thus the term "Supermoon."
It's usually difficult to tell the difference between a regular Moon and a supermoon, but comparing two pictures side by side reveals a size difference.
What is a lunar eclipse?
A lunar eclipse occurs as the Earth passes between the Sun and the Moon, preventing the Moon from receiving sunlight. There are two types of eclipses: partial and absolute, depending on how much of the Moon is obscured by the earth's shadow. This can only happen when the Moon is full.
Half of the moon, like the Earth, is illuminated by the sun at any given moment. When the Moon and the Sun are on opposite sides of the Earth, it is called a full moon. This allows you to see the entire lit-up side, which appears in the night sky as a circular disc. If the moon's orbit was flat, every full moon would be a lunar eclipse.
However, the moon passes across the same horizontal plane as both the Earth and the Sun twice during each lunar orbit. The sun, the Earth, and the moon will form a straight line if this corresponds to a full moon, and the moon will move through the Earth's shadow. A complete lunar eclipse occurs as a result of this.
The total lunar eclipse on May 26 occurs when the Moon and Sun are on opposite sides of the Earth, forming a straight line that fully covers the Moon.
What is Red blood Moon?
When the Moon is obscured by the earth's shadow during an eclipse, it darkens but does not become totally black. Instead, the Moon turns red, which is why a complete lunar eclipse is also known as a red or blood moon.
Sunlight includes all visible-light colors. Blue wavelengths of light are more likely to be scattered by the gas particles that make up Earth's atmosphere, while redder wavelengths pass through. Rayleigh scattering is what causes the sky to be blue and sunrises and sunsets to be red.
The red light will pass through the Earth's atmosphere and be refracted – or bent – toward the moon during a lunar eclipse, while blue light is filtered out. During an eclipse, this gives the moon a pale reddish hue.
Where will the super moon be seen?
The eclipse will also be visible in the area encompassing South America, North America, Asia, Australia, Antarctica, the Pacific Ocean, and the Indian Ocean, according to the India Meteorological Department (IMD).
From India, the partial phase of the eclipse will be visible for a brief period of time just after the moonrise from the north-eastern parts of the country (except Sikkim), some parts of West Bengal, some coastal parts of Odisha, and the Andaman and Nicobar Islands.
The eclipse will be seen in Agartala, Aizawl, Kolkata, Cherrapunji, Cooch Behar, DiamondHarbour, Digha, Guwahati, Imphal, Itanagar, Kohima, Lumding, Malda, North Lakhimpur, Paradee, Pashighat, Port Blair, Puri, Shillong, Sibsagar, and Silchar.
The complete lunar eclipse will be visible near moonset in the United States and Canada, Mexico, Central America, Ecuador, western Peru, southern Chile, and Argentina, according to Nasa. The complete eclipse will be apparent just after the moonrise around the Asian Pacific Rim.
Apart from India, Nepal, western China, Mongolia, and eastern Russia will also witness the partial eclipse.
