Next Friday, July 27, Brazil will see what should be the longest total lunar eclipse of this 21st century.
In the country, the beginning of the The total phase of the eclipse will be at 16:30 and the end will be at 18:13, Brasília time. The lunar eclipse will last approximately 1 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 be considered only as partial.
The Observatory says 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 horizon in the east .
From 18:13, the moon will begin to emerge from the darkest shadow. At this moment begins the partial eclipse, which goes up to 19:19. At this time, the Moon will begin to enter the lighter shadow, which marks the phase of the eclipse, which will end at 20:30.
What's an eclipse? What's 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 sunlight.
The eclipse occurs because the moon enters the shadow created by the Earth.
What is the "moon of the blood"?
When a total eclipse occurs, the moon takes on a reddish or orange color, so some people call it the "moon of blood" phenomenon.
According to the National Observatory, when the whole moon is in the shadow of the Sun, we see the satellite even though it does not directly receive sunlight, because the sunlight reaches the surface of the Moon through the atmosphere. Earth Some frequency bands of the sun 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.
After all, why will it be the longest eclipse of the century?
The researcher of the National Observatory Josina Nascimento says that "all is only a question of geometry: in this eclipse, the Moon will pbad right in the center of the shadow of the Earth".
The researcher says that it's easy to see several planets in the sky in July, especially 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 visible also in the early evening to the east and Mars is in maximum brightness, is visible in the early evening. "
She recalls that the next total eclipse of the Moon will be the night of 20 to 21 January 2019, when, she said, "all Brazil will see the total eclipse of the Moon from beginning to end".
