The sky of Brazil will be the scene of a rare show in dawn of March 14, 2025: one eclipse total yes take Visible at all stages – penumbral, partial and total. The event may be accompanied with the naked eye, without the need for instruments, and will be broadcast live by National observatory on your YouTube channel from 0.30 am.
A natural show starting before dawn
According to astronomous Josina Nascimento, from Communication Division and Popularization of the Science of the National Observatory (Is/mcti), the phenomenon begins when the moon enters the penumbra From the earth, receiving less direct sunlight.
Following, the satellite goes to Umbra, the darkest region of the earth’s shadow, starting the partial phase. When it is totally immersed in this shadow, the total phase, the most anticipated moment of the night occurs.
According to Brasilia time, the eclipse stages will be:
In some regions, the final phases will not be visible, as the moon You will be putting yourself. “Every total eclipse goes through the penumbral and partial phases before and after the total phase,” explains Josina.
Where and how to observe
The moon will be well positioned in west throughout the phenomenon. To accompany, just choose a place with free horizon In that direction. In Rio de Janeiro, for example, at the beginning of the totality the moon will be approximately 30 ° high and, in the end, the 19°.
A tip to estimate this measure is to stretch your arm and open your hand: the distance between the thumb and the little one is equivalent to about 15°. Because it is visible to the naked eye, no protection or optical equipment is required.
Why the moon gets reddish
During the total phase, the moon does not receive direct light from the sun, but is still illuminated indirectly. THE terrestrial atmosphere Disperses the blue and violet colors, letting out the reddish tones. This gives the satellite the famous color known as Blood moon.
“The closest shades of red cross the atmosphere more easily, giving the moon this characteristic color,” details the astronomous.
The role of the National Observatory
Founded in 1827, the National Observatory, Research Unit of the Ministry of Science, Technology and Innovation (MCTI)operates in areas like astronomy, geophysics e Metrology in Time and Frequency.
In addition to research and academic training, the institution plays an important role in scientific disseminationbringing the population closer to events such as lunar eclipse.
The live transmission of this phenomenon is another initiative to popularize knowledge and arouse interest in the study of heaven.
