Look at the sky in the early evening of this Friday, 27, will be a mandatory invitation. From 16:30 begins the longest lunar eclipse of the 21st century, which should last about an hour and 43 minutes. In almost the entire planet, it will be possible to follow the phenomenon that usually occurs twice a year, with a duration of 60 to 80 minutes, and may even last much less.
In Salvador
The Moon will be born 17:22, when the sky will be clear again
"Now the Moon will pbad well in the center of the Earth's shadow," said researcher Josina Nascimento of the National Observatory.And that is why it will take him more time to reappear.But in Brazil, this phase of the eclipse will not be visible during the entire period of 104 minutes. "The whole party Eastern Brazil will see the moon rise already during the total eclipse. According to the place, in Rio de Janeiro, for example, the Moon will be born at 17:26, when the sky will be clear again. Around 18:13, it becomes more visible and that is when the partial eclipse begins [quando a Lua começa a sair da sombra da Terra]. "
The lunar eclipse occurs when the Sun, the Earth and the Moon are aligned in this order.The Sun, illuminating the Earth, makes a shadow in the space in two parts: the half-light, which still reveals the rays of the Sun, and the shadow that receives no ray of light. "When the Moon, while traversing the Earth, penetrates completely into the dark shadow, we have l & # 39; total eclipse. "
In Brazil, throughout the eastern part of the country, the Moon will be born in the total phase of the eclipse, a phase that ends at 18:13, Brasília time. the Moon begins to emerge from the darkest shadow of the Earth [umbra] triggering the partial eclipse, which lasts until 19:19. The complete phenomenon, which includes the penumbral phase of the lunar eclipse, ends at 8:29 pm According to Josina, the total eclipse will be observed in the South, Southeast and Northeast regions. part of the North Region will see the partial eclipse and the most western part of the North Region will only see the penumbral eclipse. "
If the time of the phenomenon is already without Previous, the show promises to be even bigger by the colors with which the Moon will appear on the horizon: a reddish orange effect that gives its name to the Moon of Blood, caused during the total eclipse
" After sunset you have the tone of the reddish horizon is caused by the sun's rays that pbad through the atmosphere. That is, even without seeing the sun, you still get some of that light. The red tones are the least filtered and end up accentuating more. The same thing happens in the total eclipse of the Moon: when it is totally in the shadow, it becomes totally black but still reaches the moon to the sun's rays that cross the Earth's atmosphere . "
The celestial show still promises greater visibility of the planets that will be on the same line.March, no doubt, deserves to be highlighted since the beginning of the year in maximum brightness, stinging like a red dot next to the Moon.The peak of this effect is expected for August 3, but it is impossible to ignore the presence of this planet seen with the naked eye. "Jupiter will also be at the top. Venus is in the west and Saturn will be between Mars and Jupiter in the same line, also very bright but less than Mars. "
