A full lunar eclipse with “Blood Moon” can be seen in Brazil next Sunday night (15/05), according to Roberto Costa, professor of the Center for Astronomy at the University of São Paulo ( USP).
This would be the only total lunar eclipse to occur this year, according to astronomers. The next one is only in May 2025.
Sunday Eclipse can be seen not only in Brazil, but throughout South and Central America, part of North America, part of Europe and part of Africa.
The entire lunar eclipse occurs when the sun, earth and moon coincide. With this, the whole earth covers the disk of the moon and this makes that happen. Earth’s satellite then turns red – which comes as “Blood Moon”.
The astronomy expert at USP told BBC News Brazil that the word “Blood Moon” had become popular in recent years after being used by the media.
“Perhaps this is happening in the context of the American web, but one should not lose sight of the fact that the physical phenomenon itself is a lunar eclipse. That is, the The moment when the Earth is placed between the Sun and the Moon, makes a huge impact. The Earth’s shadow is ready for the Moon, “said the professor.
A reddish color appears, explains the professor, because the Earth’s air acts as a filter for sunlight.
“The technology is as follows: our planet air always filters sunlight, letting the red color by much and reflecting blue, so that we see the blue sky during the day. In a lunar eclipse, the Earth is exactly between the sun and the moon, in this case, in the ‘edge’ of our planet (as observed by observers), the clouds The wind creates a halo that leaves an ‘edge’ of our planet. Light too small, this light is reddened by the wind filter and will fall to the moon, which gets a reddish-brown sound “, says USP professor Roberto Costa.
He said that reddish color will vary, depending on the eclipse. It can be darker, closer to brown, or lighter, something like brown or red.
From where and when to see the moon eclipse
Lunar eclipse can be seen all over Brazil. The pastor said it would be easy to see the land because it would occur at night and the moon would be at high altitude.
According to experts, the half-eclipse can be seen from next Sunday at 11:28 pm, Brasília time. At 00:29 Monday (16/02), all eclipses will begin, which will last until 1:54 p.m.
The end of the eclipse is estimated to occur at 2:55 p.m.
The results will also be reported by the National Observatory, a research unit affiliated with the Ministry of Science, Technology and Innovation. The broadcast will start from 23:15 at this link.
Can I watch an eclipse without eye protection?
As it is a lunar eclipse, astronomers interviewed by BBC News Brasil have said that observing it directly does not pose a risk to the eye.
“It is important to look at the full moon. You do not need the equipment, with the naked eye it’s already beautiful. If someone wants, they can also use the camera pictures, glasses or spectacles. “, said USP professor. .
As the eclipse will occur at the end of the night and the beginning of the dawn, the moon will be very high in the sky, which will contribute to the visualization of the phenomenon.
The USP astronomer has only one concern.
“The only problem is the weather. The forecast is for the weather forecast for the southern region on Sunday. If it were that way, we at São Paulo would miss the show”.
