The Greatest Lunar Eclipse of the Century
Next Friday, July 27, Brazil will see what will be the longest total lunar eclipse of this 21st century.
In the country, the beginning of the total phase of the eclipse will be at 16:30 and the end will be at 18:13, at the time of Brasília. The lunar eclipse will last about an hour and 40 minutes
According to the National Observatory, the eastern part of Brazil will see the total eclipse – in the western part, the eclipse will only be considered as partial.
The Observatory said that to see the moon still in the total eclipse, people should look for a place where it is possible to see the sky near the eastern horizon.
From 18h13min the moon will begin to emerge from the darkest shadow. At this moment begins the partial eclipse, which goes up to 19:19. At that moment the Moon will begin to enter the lightest shadow, which marks the penumbra phase of the eclipse, which will end at 8:30 pm
What is & ### 39, An Eclipse
An eclipse occurs when the Sun, Earth, and Moon align. This causes the Earth to be directly between the Sun and the Moon, blocking the sun's light.
The eclipse occurs because the moon enters the shadow created by the Earth.
What is the "blood moon" When a total eclipse occurs, the moon takes on a reddish or orange color, so some people call it "blood moon."
According to the National Observatory, when all The Moon is immersed in the shadow of the Sun, we see the satellite even though it does not receive direct sunlight, because the light of the sun reaches the surface of the moon through the atmosphere of the Earth. Some sun frequency bands are then filtered, creating this orange effect, just like in the morning and evening twilight, we are used to seeing before sunrise and after sunset.
There is no need to use a telescope, but a good pair of binoculars can help.
Why is this the longest eclipse of the century? The researcher of the National Observatory Josina Nascimento says that "everything is matter of geometry: in this eclipse, the Moon will pass to the center of the Earth's shadow."
The researcher says that it's easy to see more planets in the sky in July. Mars, which will be close to the moon on the day of the eclipse. "Several planets are visible to the naked eye in the sky: Venus is visible in the west after sunset, Jupiter is already high in the sky when the sun sets, Saturn is also visible in the beginning evening in the east and Mars is at maximum brightness, is visible in the east at the very beginning of the night. "
It recalls that the next total eclipse of the Moon will be in the night of January 20 to 21, 2019, when, she said, "the whole of Brazil will see the total lunar eclipse from beginning to end."
