Anonymous users2024-02-11Process. The beginning of the penumbral eclipse after a total lunar eclipse: The Moon has just made contact with the penumbra and the lunar eclipse is perceived by the naked eye.
No, no. The process of the official lunar eclipse is divided into five stages: the first loss, the eclipse, the eclipse, the rebirth, and the recuperation. 1.
Beginning of a penumbral eclipse: When the Moon has just made contact with the penumbra, the luminosity of the lunar surface decreases slightly, but it is less perceptible to the naked eye. 2.
First Lunar Eclipse (Partial and Total Lunar Eclipse Only): Marks the beginning of a lunar eclipse. The Moon slowly enters the Earth's shadow from the eastern edge, and the Moon and the Earth's umbra are incised for the first time.
3.Eclipse (total lunar eclipse only): The Moon enters the Earth's umbra and is inscribed with the umbra for the first time.
The Moon just went all the way into the Earth's umbra. 4.Food:
The moment when the center of the full moon is closest to the center of the Earth's umbra, the surface of the moon before and after it is reddish copper or dark red. (Reason: When sunlight passes through the earth's atmosphere, it is refracted and the light is deflected inward, but the degree of deflection (dispersion) is different for each light, and the red light is the most deflected, closest to the Earth's shadow, and is reflected on the moon; In addition, the amount of light deflection varies depending on the amount and location of dust and clouds in the atmosphere, so the Moon during a total lunar eclipse will be dark red, copper, or orange.
In the same way, the morning sun and the sunset are not white due to the refraction of the atmosphere, but orange or red depending on the altitude due to the degree of refraction of the atmosphere. ） 5.Raw light (total lunar eclipse only):
The Moon moves within the Earth's umbra and is inscribed with the Earth's umbra for the second time. The eastern edge of the Moon is intangent to the eastern edge of the Earth's umbra, at which point the total eclipse phase ends. 6.
Rounding (partial and total lunar eclipses only): The Moon gradually leaves the Earth's umbra and is intangent to the Earth's umbra for the second time. The western edge of the Moon is tangent to the eastern edge of the Earth's umbra, at which point the eclipse ends.
The degree to which the Moon is eclipsed is called "eclipse", which is equal to the ratio of the farthest distance between the edge of the lunar ring and the Earth's umbra at the time of the eclipse to the Moon's visual meridian. 7.Penumbral Eclipse End:
The Moon leaves the penumbra, and the entire lunar eclipse process officially ends. There is no eclipse or light generation process, and the eclipse only indicates the closest moment to the Earth's shadow. The magnitude of a lunar eclipse is expressed in terms of eclipse.
The eclipse is equal to the ratio of the apparent diameter of the moon to the apparent diameter of the moon when it enters the umbra at the time of eclipse. When the eclipse is like the moon and the umbra incision, the eclipse is equal to 1. When an eclipse is like the moon going deeper into the umbra, the eclipse is represented by a number greater than 1.
A total lunar eclipse is an eclipse greater than or equal to 1. Partial eclipses have less than 1 in size. The eclipse of a penumbral lunar eclipse is expressed as the ratio of the part of the moon's diameter that enters the penumbra to the apparent diameter of the moon.
The eclipse of the penumbral moon is only perceptible to the naked eye when the eclipse is larger.

Anonymous users2024-02-10A lunar eclipse is a special astronomical phenomenon in which when the Moon moves to the shadow part of the Earth, the area between the Moon and the Earth will be obscured by the Earth's rays, and a piece of the Moon will be missing. The Sun, Earth, and Moon at this time happen to be (or almost) in the same straight line.

Anonymous users2024-02-09To put it simply, the moon --- the earth - the sun moves in a straight line, the earth is between the moon and the sun, at this time the moon is covered by the shadow of the earth, people can not see the moon, this is the lunar eclipse.

Anonymous users2024-02-08A lunar eclipse, also known as a lunar eclipse, is a natural phenomenon. When the Sun, Earth, and Moon happen to be or are almost in the same straight line (the Earth is between the Sun and the Moon), the Sun-to-Moon rays are partially or completely obscured by the Earth, resulting in a lunar eclipse. There are three types of lunar eclipses: partial lunar eclipses, total lunar eclipses, and penumbral lunar eclipses.
A partial lunar eclipse occurs when the Moon enters only part of the Earth's umbra; And when the entire Moon enters the Earth's umbra, a total lunar eclipse occurs. As for the penumbral lunar eclipse, it means that the moon only passes over the penumbra of the earth, causing a very slight decrease in the brightness of the lunar surface, which is difficult to see with the naked eye, so it is not noticed. Isn't that interesting?

Anonymous users2024-02-07A lunar eclipse is an astronomical phenomenon in which a bright moon is suddenly blocked by a large black shadow, and it was called "Tiangu eating the moon" in ancient Chinese folklore. In fact, the sun, the earth, and the moon are roughly located in a straight line, and because the earth is centered at this time, it is essentially the moon that drills into the earth's shadow cone, and the moon itself does not shine, and when it reaches the earth's shadow, it does not get sunlight, and it is basically invisible. Obviously, a lunar eclipse is only possible at the "wang" (full moon), which is the half-moon or sixteenth of the lunar calendar.
In the same way as a solar eclipse, most of the "hopes" do not have a lunar eclipse, and only a few "hopes" with the three in a straight line will people see this moving lunar eclipse scene. The number of lunar eclipses per year is a minimum of 0 (no lunar eclipses throughout the year) and a maximum of 3.

Anonymous users2024-02-05A total lunar eclipse occurs because the Sun, the Earth, and the Moon are in a straight line. The Earth blocks the sun's rays from the moon and a lunar eclipse occurs. Before the lunar eclipse, the "red moon plum pi bright" is because the moon has just passed through the shadow area of the earth, and the earth's atmosphere can attract other light waves with shorter light waves, while the red light wave is very long, which will be projected directly onto the surface of the moon, and when it is reflected back to the earth, we see the "red moon".
in the lunar calendar. Ten.
5. 16. The moon moves in the opposite direction to the sun. At this time, if the center of the Earth and the Moon are roughly in the same straight line, the Moon will enter the Earth's umbra and produce a total lunar eclipse. >>>More
Causes of solar eclipses.
A solar eclipse is when the Moon circles the Earth and turns between the Sun and the Earth, which is the first day of the lunar calendar. If the Sun, Moon, and Earth are aligned in or close to a straight line, the Moon blocks the sunlight that hits the Earth, and the dark shadow behind the Moon falls on the Earth, and a solar eclipse occurs. People in the shadow of the moon on the earth began to see the sun gradually weakening, the sun surface was obscured by a round black shadow, when the sky turned dark, all the brightest stars and planets could be seen in the sky, and after a few minutes, the sun gradually appeared from the edge of the moon's black shadow, and began to produce light and recircle. >>>More

There are two ways in which diamonds are formed, one is formed by the high temperature and pressure of the earth, and the other is formed by graphite-carrying meteorites and the impact of the earth, both of which are more demanding, so diamonds are very precious. Most of the diamonds on the market are formed under high geological temperature and high pressure, and the formation location is deep in the earth, and the temperature is between 1100 and 1500. >>>More
Tsunamis are usually caused by the seafloor with an epicenter within 50 km below the seafloor and above the Richter scale. The wavelength of the tsunami is larger than the maximum depth of the ocean, and the propagation near the seabed is not much hindered, regardless of the depth of the ocean, the wave can propagate past, the tsunami propagation speed in the ocean is about 500 to 1,000 kilometers per hour, and the distance between the two adjacent waves may also be as far as 500 to 650 kilometers, when the tsunami wave enters the land shed, due to the shallow depth, the wave height suddenly increases, and the waves rolled up by its wave movement can reach tens of meters high, and form a "water wall". >>>More
