On Sunday, the world will see the only lunar eclipse in 2019, when the shadow of the Earth falls on the moon, turning the moon into a reddish orange.
The total eclipse of the moon is visible in the western half of the Earth, in Europe, in western Africa and in northern Russia, weather permitting, attracting about 2.8 billion viewers.
The Americans have the best view of eclipses, appearing in the sky at 9:36 pm on Sunday, while in Europe they will be able to see the eclipse at dawn on Monday.
The National Aeronautics and Space Administration (NASA) said this was the first time in three years that North America has seen a lunar eclipse.
During the lunar eclipse, the moon will be a red-hot orange. It is called a "bloody moon." Its color change is due to the diffusion of the Earth's small atmospheric atoms as the sun passes through it, leaving a red color mostly her.
