On July 27th, don’t miss the longest lunar eclipse of the 21st century.


Astronomy enthusiasts will be served. On the night of July 27-28, the longest observable lunar eclipse of the 21st century will take place, lasting 103 minutes, according to NASA data. This infrequent event will be a breathtaking spectacle lasting exactly 1 hour and 43 minutes. The last eclipse of this type took place on January 31 and lasted 1 hour 16 minutes, again according to the space agency.

The episode, which is the longest episode ever recorded between 2000 and 2100, is therefore a moment to mark in his calendar and not to be missed. It will take place between sunset (around 9:30 pm) and midnight, and will be visible from almost all of Europe (including Paris, London and Rome), Asia, Australia, Africa and South America.

The eclipse is the moment when the Earth comes between the Moon and the Sun. The three elements are then perfectly aligned. It is said « total » when the Moon disappears entirely into the Earth’s shadow, which will be the case on July 27th. On that date, the total eclipse will be surrounded by two other « partial » (when the alignment is imperfect) which will last 3 hours 23.

Already extremely rare, this phenomenon will be doubled by another one just as rare exceptionnel : the possibility of our distant neighbour appearing brighter than ever  : Mars. At the end of July, the Red Planet will be in a position in its orbit that will place it just under 58 million kilometres from us. This proximity will not be reached again for another 15 years or so.

Finally, unlike the solar eclipse, the lunar eclipse can be seen with the naked eye and no special precautions need to be taken. A beautiful program in perspective that will undoubtedly fill the eyes of all of us with stars.
