This is when the moon changes from its traditional white hue to a deep, nearly blood-like red due to the sun's rays being reflected through the planet's atmosphere.
The longest total lunar eclipse of the century concluded Friday night, showcasing a blood moon for most of the Eastern Hemisphere. Incredible "blood" moon can be seen from different parts of the world.
"All you have to do is. go outside!" the Royal Astronomical Society (RAS) in London said, adding that binoculars would be useful to observe the phenomenon.
There is quite a long wait until the next lunar eclipse which happens on January 21, 2019.
Sources said from 11.45 pm, people were staring at the sky and the white moon was playing hide-and-seek with the clouds in Chennai.
Astronomy enthusiasts in Bern might have seen this view over the Church of the Holy Spirit as the sun, Earth and moon aligned with each other. The "totality" period, where light from the Moon was totally obscured, lasted for one hour and 43 minutes.
In a special treat, Mars is also at its closest approach to Earth this week since 2003, making it appear bigger and brighter.More news: Love Island tonight: 5 things that are going to kick off!

The Eclipse lasted about 103 minutes.
"The moon turned a attractive crimson red colour in the west and Mars was just above and left of it, looking a yellow-orange colour", he told ABC News.
This is what gives the phenomenon the name "blood moon", though Mark Bailey of the Armagh Observatory in Northern Ireland said the color can vary greatly.
Astronaut Alexander Gerst tweeted: "A partially eclipsed Moon, with our neighbouring planet in the background, just before diving into Earth's atmosphere".
Unlike solar eclipse, lunar eclipses are visible with the naked eye and people do not need to wear eye protection.
Social media users were quick to post sarcastic tweets about how great their view of the celestial event was, with many bemoaning the fact that skies had been clear for weeks only to cloud up on Friday.
According to some Hindu beliefs, celestial bodies such as the sun and moon emit negative energy during an eclipse and so some temples in India were closed to minimize any disturbance.
