When does a lunar eclipse occur?
the shadow of the Moon It is divided into two zones: the umbra or shadow, which is the dark portion with a cone profile, and the penumbra, which is what remains in its surroundings. Thus, lunar eclipses can only occur during the full moon phase, so that when the three bodies (mentioned above) are arranged, the Moon enters the cone of shadow that is projected towards the Earth in space. Furthermore, this phenomenon is one of the many interesting aspects of the moon as a satellite. For those who wish to learn more about the different types of eclipses, you can refer to How many types of eclipses are there?.
Also, the first excitement is to speculate that an eclipse should happen every month with every full moon, but it doesn't thanks to the fact that the moon's orbit is cornered in relation to the ecliptic plane (the arcuate line where the moon "passes"). sun near the Earth, in his "figurative current" noted from Earth).
Representation of a lunar eclipse phenomenon
Inversely to solar eclipses that can only be noticed from a segment of the Earth, a phenomenon eclipse Lunar eclipses can be observed from any part of the Earth where it is nighttime. Thus, lunar eclipses can last for many hours, while solar eclipses are only visible for a few moments. To learn more about the differences between eclipses, you can consult the classification in , as well as the importance of eclipses in the mayan astronomyFor more information on other astronomical phenomena, go to astronomical phenomena of this year.
In another sense, it is also important to note that we can see the lunar eclipses directly, with binoculars or telescope; while solar eclipses must be seen with eye protection.
super blue blood moon phenomenon
The word refers to a Moon that is full when it is closest in its orbit to the Earth. Regarding the above, various scientists point out that the orbit of the Moon It's very prolonged, and at times when the Moon is full, it coincides with the Moon's proximity to our planet. They also point out that this phenomenon occurs every month; that is, the Moon approaches and moves away from us as it continues its orbit. However, if the approach coincides with the full Moon, it is called a supermoon. For more information about the blood moon, visit Luna de sangre, since it is closely related to lunar eclipses.
In this way, the Moon's orbit is elliptical, and one side is about 50.000 km further away from the Earth. Earth than the closest one, designated perigee. Furthermore, researchers state that when the Moon is perceived to be 10 to 15% larger than a smaller one, the change is enormous and can be appreciated just by looking at it. Furthermore, the supermoon will also be the second full Moon observed in January of this year.
Other investigations concerning the blood moon
Eclipse viewers were able to observe a huge reddish Moon, haunted as the Moon of blood. In this case, the Moon's hue during a total lunar eclipse is due to our planet's atmosphere. This is why, if we were on the Moon at that moment, we would see the Earth pass before the Sun. The Earth appears as a black wheel, but we realize that the Earth has an atmosphere, and the light passing through the atmosphere toward the Moon is bent. Furthermore, this phenomenon is an example of the .
In this sense, the red portion of the light reaches the Moon. If we were on the Moon we would see the same hue that is evident in a sunset. But in this case it would be a twilight sun that would be distinguished as a red ring near the Earth And that is the luminary that comes to illuminate the Moon and that is why it looks red. For those interested in a more child-friendly approach to astronomy, there are resources available at astronomy for children.
Light scattering is what further exposes red sunsets on Earth. And this phenomenon has nothing to do with the path that the light must travel, but with the angle at which the sparks of the Sol they return to us
On the other hand, in the case of red twilights, what happens is that there are elements in the atmosphere of our planet, especially water, nitrogen, oxygen. They are molecules that scatter blue light, which is why the sky is distinguished by a bluish hue during the day. Likewise, when the Sun hides or before the Sun rises, the red light subdues in that minute since it is the light that crosses the atmosphere more easily. Finally, the researchers state that the next time these anomalies agree will be in 19 years, specifically on January 31, 2037.
3 lunar eclipse phenomena
In this sense, a phenomenon eclipse mole can be classified as follows:
partial lunar eclipse phenomenon
In this case it is only a portion of the Moon which will be hidden. For more information on eclipse classification, see .
total lunar eclipse phenomenon
On the other hand, for a total lunar eclipse to occur, the entire surface of our natural satellite must enter the shadow cone of the Earth. land And this is something that happens in different types of eclipses. If you want to learn more about the types of eclipses, you can check out the lunar eclipse phenomenon.
penumbral lunar eclipse phenomenon
Here, the Moon enters the Earth's shadow cone. It is important to note that the time it lasts and also the type of eclipse we are dealing with will depend on the orientation of the Moon in relation to its vibrations. orbitals.
Did you know?
As opposed to solar eclipses, which can be distinguished only from a relatively small segment of the Earth and last only a few minutes, a phenomenon de A lunar eclipse can be observed from anywhere on Earth during nighttime and lasts for many hours. This is one of the characteristics that makes it so special. You can learn more about it.
Cone of darkness and shadow in a lunar eclipse phenomenon
El Sol It has an equatorial path 109 times larger than our planet's, in that sense, it directs an analogous shadow cone and an opposite penumbra cone. Eclipses occur because the Moon, which is located about 384 km from Earth, enters the Earth's shadow cone, which is much larger—to be more precise, it would be about 000 km.
Also, at the distance from the Moon Earth's cone of darkness has a diameter of 9200 km, while our natural satellite's diameter is 3476 km. This large discrepancy means that 2,65 times the Moon's diameter can enter the cone of darkness, and as a result, eclipses persist throughout their total period for a very long time. If you'd like to learn more about astronomical phenomena, you can consult .
To a person on the surface of the Moon, a penumbral eclipse would be a eclipse Similarly, if said individual were inside the cone of darkness of the Earth, he would not be able to see the star, so that for him a total lunar eclipse of the Sun phenomenon would be originating.
Similarly, the earth's atmosphere has a vital domain in eclipses. If the atmosphere were not there, in each total lunar eclipse phenomenon, our satellite would never be observed again (which we know does not happen). The totally eclipsed Moon gets a reddish hue of its own due to the light modified by the atmosphere of our planet. To calculate the degree of darkness that would be generated from lunar eclipses, the Danjon scale is used.
