A blood moon dominates the sky in much of the world on Friday, as the Earth's natural satellite is moving into the shadow of the planet during the longest lunar eclipse of the 21st century.

The total eclipse will last one hour, 42 minutes and 57 seconds, although it will precede it and will be followed by a partial eclipse, which means that the Moon will be in total 3 hours and 54 minutes in the shadow of Earth, according to NASA.

Around the world, from the Taj Mahal to the Eiffel Tower, people will look to the sky in hopes of seeing the blood moon, which will look orange, brown or red as sunlight shines on the moon. atmosphere.

The total eclipse, at 2022 GMT, will be visible from Europe, Russia, Africa, the Middle East, much of Asia and Australia. Hundreds of people in Australia paid to observe the eclipse from the Sydney Observatory before dawn.

"Our event is totally sold, we have a couple of hundred people who will come to watch it with us," said Andrew Jacob, curator of the Sydney Observatory, located near the Harbor Bridge.

When the Moon moves towards the conical shadow of the Earth, it will go from being illuminated by the Sun to staying in darkness. However, a little light will still reach it because it will be refracted in the Earth's atmosphere.

"It's called Blood Moon because the Sun's light passes through the Earth's atmosphere on its way to the Moon and the Earth's atmosphere turns it red in the same way that when the Sun hides, it turns red", told Reuters the professor of astronomy of the University of Cambridge Andrew Fabian.

At the same time, Mars will be at its closest point to Earth since 2003, so that observers can see what it will look like a red-orange star.

"It is a very unusual coincidence to have a total lunar eclipse and Mars in opposition on the same night," said Robert Massey, executive deputy director of the Royal Astronomical Society, who will try to observe the eclipse from the Mediterranean Sea.

The lunar eclipse will not be visible from North America or from most of the Pacific and the next one of such long duration will take place in the year 2123.
