This phenomenon occurs twice a year when the Sun, Earth and Moon are properly aligned and the Moon is in its full phase.

Eclipse of about five hours

“During an eclipse, only the Earth can illuminate the Moon by emitting these red rays again.2, the astronomer continues. “It is very interesting that the white and brilliant moon takes on a red and off hue in a few minutes.“, He adds. As seen with the naked eye, visible in a telescope, the event can giveSpectacular photosIf the weather is good. The eclipse lasts about five hours, and its full phase – when the star is completely in the shadow of the earth – lasts more than an hour.

“It is best to observe from the West Indies or Guyana as the Moon is very high in the sky“According to the laboratory, the eclipse will be fully visible in South America, Central America and the eastern part of North America. Keep in mind that at the same time as the sun rises, the full moon disappears at this point, so if you are in the west of France it will be much easier to observe this event in the late sunrise than in the east.
