In recent years, China has been able to see lunar eclipses one after another, when will foreign coun

About lunar eclipses: Lunar eclipses all occur on the fifteenth or sixteenth lunar calendar. Of course, it was also the same day!

Hehe, to paraphrase a common saying: the end of the world is this "food". For example, when a lunar eclipse occurs, half of the world (visible in the night hemisphere).

It's just that they don't have a lunar calendar. A lunar eclipse has an eclipse season of 24 days, which is shorter than the average number of days in a synodic month. Therefore, a lunar eclipse may or may not include a lunar eclipse during a lunar eclipse, that is, there may or may not be a lunar eclipse during this eclipse season.

There are also two eclipse seasons in a year; "So in a year, there may be two lunar eclipses, or not even one. <>

The first lunar eclipse of the year will be visible from parts of Europe, Africa, Asia and Australia, and if weather permits, observers in those regions will see a bizarre Full Moon on Friday, January 10. However, North and South America will miss out on this lunar spectacle, and luckily, as a consolation, a few hours later, January's Full Moon will appear in skies around the world. Whether it's at moonrise or moonset, you can see this amazing full moon.

Penumbral lunar eclipse, June 5, maximum lunar eclipse occlusion of 59%, visible in Europe, Africa, Asia and Australia; Annular solar eclipse, on June 21, the annular eclipse can last up to 38 seconds and will be visible in central Africa, South Asia, China and the Pacific Ocean; Penumbral lunar eclipse, July 5, maximum lunar eclipse occlusion of 36%, visible in the Americas, southwestern Europe, and Africa; Penumbral lunar eclipse, November 30, maximum lunar eclipse occlusion rate of 74%, visible in Asia, Australia, the Pacific Ocean and the Americas; Total solar eclipse, December 14, can last up to 2 minutes and 10 seconds and will be visible in the South Pacific, Chile, Argentina and the South Atlantic. <

In addition, it has been found that there are other cycles of solar and lunar eclipses. The exact time of solar and lunar eclipses and the situation of eclipses need to be calculated strictly and specifically, which is already within the scope of the "food theory" in almanac astronomy. <>

In fact, when China can see the lunar eclipse, it should also be visible abroad, but we don't pay attention to foreign news, and generally when the planets are connected in a straight line, we can also see the lunar eclipse.

Because in recent years, China's planetary orbit is relatively special, and lunar eclipses can be seen in China and abroad.

As long as you are in the northern hemisphere like China, you can see the lunar eclipse at the same time as China!

As long as it's not on the back side of China, then other regions can also see the eclipse like China.

The time of the lunar eclipse in 2018.

A total lunar eclipse is a type of lunar eclipse, when the moon, the earth and the sun are completely in a straight line, the moon will all enter the shadow of the earth, and the astronomical phenomenon of a total lunar eclipse will appear. Because of the lack of knowledge in astronomy, the ancients in China once called this celestial phenomenon "Tengu Eating the Moon", but at this time the moon did not disappear, but its surface was dim, or showed a rare bronze color, and it has always been the object of observation for astronomical enthusiasts.

According to astronomical forecasts, there will be two total lunar eclipses in China in 2018. More importantly, these two total lunar eclipses can be seen by the public in China, which can be described as a good opportunity for astronomical observations. Now let's sort out the two total lunar eclipses in 2018 as follows:

January 31: Total lunar eclipse (first eclipse 19:47, eclipse 21:30, rebirth 23:10).

July 28: Total lunar eclipse (2:25 a.m., 4:22 p.m., 6:20 p.m

From a global perspective, lunar eclipses occur almost every year, but total lunar eclipses do not occur every year. In a specific region or country, the chance of seeing a total lunar eclipse is even smaller. Therefore, these two total lunar eclipses visible in China can be said to be quite valuable astronomical observation opportunities.

In 2018, the public in our country had the privilege of enjoying these two total lunar eclipses. The time of occurrence was January 31, 2018 and July 28, 2018, respectively. Among them, on January 31, the closest to us, the first waning moment is 19:47, the reunion moment is 23:10, and the total eclipse phase lasts for more than 1 hour; The total lunar eclipse on July 28 will have a first eclipse of 2:25 and a return of 6:20, and the total eclipse phase will last for 3 hours and 55 minutes.

Hope it helps.

Not a few times, it's hundreds of times, what are you going to do.

When a lunar eclipse occurs, it is impossible for us to observe an annular lunar eclipse.

The diameter of the earth is much larger than the radius of the moon, and the distance between the moon and the earth is small, when the moon, the earth, and the sun are in a line, and the earth is between the sun and the moon, forming a lunar eclipse, due to the small distance between the earth and the moon, the moon cannot be in the pseudoumbra range, and its earth shadow can completely cover the moon, so no annular lunar eclipse will occur.

It's actually very simple, as long as you can see the moon. It may seem nonsense, but it's absolutely true, so when a lunar eclipse occurs, about half of the Earth will be visible.

And because the sun and moon are located on opposite sides of the sky during the lunar eclipse, as long as the sun is not visible at the time of the occurrence, the moon will definitely be visible, that is, as long as it is night, it doesn't matter if the first half of the night and the second half of the night are fine.

The principle of a lunar eclipse. 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. If only part of the Moon enters the Earth's umbra, a partial lunar eclipse occurs.

When the Moon enters the penumbra of the Earth, it should be a penumbral eclipse, but because its brightness is weakened very little and it is not easy to detect, it is not called a lunar eclipse, so there are only two kinds of lunar eclipses: total lunar eclipses and partial lunar eclipses.

Lunar eclipses occur in the hope (full moon), but not every lunar eclipse occurs, which is the same as not every solar eclipse. In general, the Moon either passes above or below the Earth's umbra, rarely passing through or partially passing through the Earth's umbra, so a lunar eclipse generally does not occur. Lunar eclipses occur up to 3 times a year, and sometimes none at all.

Therefore, the Mid-Autumn Festival may encounter a lunar eclipse

Watching a solar eclipse from the moon? The Earth Blocks Daylight? Then the earth is between the sun and the moon.

A solar eclipse occurs on Earth when the moon blocks the sunlight, and the moon is between the earth and the sun.

So when you see a solar eclipse on the Moon, you can't see it on Earth.

But you should consider the size ratio of the Earth to the Sun as seen on the Moon, because the Earth is very close to the Moon, so it may be larger than the Sun relative to the Sun, so in this case, there will be no phenomenon of the Earth's shadow eating away at the Sun little by little, but the smaller Sun slowly moves behind the Earth, just like the sun sets.

At the same time, considering the diffraction of light, the dividing line between the sun and the earth's margin should be a spot of light and cannot be seen clearly.

Therefore, although the earth blocks the sun, it may not look the same as the usual lunar and solar eclipses

If a lunar eclipse is seen on Earth, then a solar eclipse will be seen in parts of the Moon.

What will be seen in the Earth's shadow part of the Moon will be a total solar eclipse.

What is seen in the bright part of the Moon (when it is a partial lunar eclipse on Earth) may be seen or not.

A 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. At this time, the sun, the earth, and the moon are just right.

or almost) in the same straight line. Lunar eclipses can be divided into three types: partial lunar eclipses, total lunar eclipses, and penumbral lunar eclipses. Lunar eclipses can only occur around the 15th day of the lunar calendar.
