By second time in 2022a total lunar eclipse can be seen in the night sky, and the event will be visible from Mexico. This is one of the few occasions where two phenomena occur in the same year, since they normally occur every 1.5 years on average and it will be “special”, since the next it won’t happen again until 2025.
To be able to see the 2022 Blood Moon, it will be necessary to be aware of the satellite During the early hours of Tuesday, November 8and since it can be seen in the country, the only thing we will need is to know the hours in which it will be shown and a clear sky.
How to see the 2022 Blood Moon from Mexico
In the case of Mexico, the lunar eclipse will start at 2:02 a.m. Central Mexico time, and will have a duration of four hours and 46 minutesdivided into the following stages:
- at 2:02 a.m.will officially start the penumbral eclipse, where as its name says, the penumbra of the Earth will begin to touch the face of the Moon
- at 3:09 a.m.the partial eclipse will begin, where we will see the satellite turn red
- at 4:16 a.m. the total eclipse will begin, a stage in which the completely red Moon will be seen
- at 4:59 a.m. it will be the best time to see the event, since the eclipse will be at its maximum point, with the Moon closer to the center of the shadow
- at 5:41 a.m. The total eclipse will end, but it will still be possible to see it from Mexico a little more until 6:34 am, when it will be interrupted by the sunrise.
By what is the blood moon red?
A total lunar eclipse occurs when Earth casts a full shadow, which is called “umbra”, on the Moon. The shadow of our planet is classified into two parts, umbra, that is, the innermost part of the shadow, where the direct light of the Sun is totally blocked, and penumbra, the outermost part of the shadow where the light is partially blocked.
During these events, the Moon and Sun are on opposite sides of the Earth, and only occur when the orbits align so the satellite is directly behind the planet relative to the Sun.
In this case, the red color occurs due to refraction, filtering and scattering of light by the Earth’s atmosphere. In the case of scattering, it is also known as Rayleigh scattering and the reason red sunrises and sunsets exist.
Sunlight collides with gases in the atmosphere and due to its shorter wavelength, blue light is filtered out, but red light is not easily filtered out as it has a longer wavelength. Some of this red light is bent (refracted) as it passes through the Earth’s atmosphere and ends up shining on the moongiving the characteristic color, although the degree of redness can be influenced by the atmospheric conditions of volcanic eruptions, fires and even dust storms.
for this event no eye protection neededas it can be seen with the naked eye, although binoculars or a telescope can improve the view.
