Blood Moon 2018: World witnessed longest Lunar Eclipse of the century

On the night of July 27-28, 2018, stargazers across the world witnessed a spectacular celestial phenomenon 'Blood Moon 2018'.  

Blood Moon or Total Lunar Eclipse, a rare celestial event, is considered to be the longest total lunar eclipse of the 21st century which lasted beyond 100 minutes.

Places where the Total Lunar Eclipse was visible?

The Blood Moon 2018 was first visible in India from around 10:44pm, while its capital New Delhi was right between the action of the full total eclipse at around 1 am midnight which ended at 2.43am.

It was majorly seen in the Eastern Hemisphere including Central Asia and Eastern Africa. The best view of the entire eclipse was visible across the Eastern Europe, Central and East Africa and South East Asia.


In July 2018, the Full Moon, as well as the Lunar Apogee Fall, occurred on the exact same date, which is July 27. The Lunar Apogee is said to be the moon’s farthest orbital point from the Earth, which makes it appear particularly small and distant.

The longest Total Lunar Eclipse

• The first part of the lunar eclipse saw the Moon fall under the Earth’s shadow called Umbra. This part of the eclipse is known as the Penumbral Eclipse.

• It coincided not only with Mars's close approach, but with the "procession of planets", a line-up of celestial neighbours Venus, Jupiter and Saturn.

• The total lunar eclipse lasted 103 minutes, that is 1 Hour 43 minutes, which made it the century’s longest.

Various stages of a Total Lunar Eclipse

Beginning of Penumbral eclipse: The outer part of the Earth's shadow begins moving across the Moon.

Beginning of Partial eclipse: The inner part of the Earth's shadow begins covering the Moon.

Beginning of Total eclipse:  The Earth's shadow completely covers the Moon, turning it into a reddish brown colour.

Maximum eclipse: The mid-point of totality

Total eclipse ends: The Earth's shadow starts moving away from the Moon.

Partial eclipse ends: Earth's shadow completely leaves the surface of the Moon.

Penumbral eclipse ends: The outer part of the Earth's shadow completely moves away from the Moon

What is Total Lunar Eclipse?

A Total Lunar Eclipse occurs when the Earth comes between the Sun and the Moon and covers the Moon with its shadow called Umbra. When it happens, the Moon can turn red, thus, earning the name of Blood Moon.
