What is the observation range of the total solar eclipse in July?

At the end of January this year, a blue blood moon drama was staged, and I believe that most of our friends have felt the visual shock brought to us by the total lunar eclipse process, and at the end of this month, a total lunar eclipse will be staged. LikeAstronomical phenomenaFriends, do I understand the concept of a total lunar eclipse? Next byKnowledge of horoscopesWhen the moon, the earth, and the sun are completely in a straight line, the earth is in the middle, and the entire moon enters the shadow of the earth, and the surface of the moon turns dark red, forming a total lunar eclipse. The process of a total lunar eclipse is divided into five stages: initial loss, eclipse, eclipse, rebirth, and recirclement. A total lunar eclipse is equal to the ratio of the farthest distance of the lunar ring rim deep into the earth's umbra and the moon's visual meridian when the edge of the lunar ring is eclipse.

The first lunar eclipse has just touched the Earth's umbra, marking the beginning of the lunar eclipse. The western bend of the eclipse is inscribed with the western edge of the Earth's umbra, and the Moon just enters the Earth's umbra. The center of the eclipse moon is closest to the center of the Earth's umbra.

The eastern edge of the Moon's light is intangent to the eastern edge of the Earth's umbra, at which point the total eclipse phase ends. The western edge of the round moon is tangent to the eastern edge of the Earth's umbra, and the whole process of the lunar eclipse ends. The magnitude of the lunar eclipse is called eclipse, astronomers have revealed that it will be the longest total lunar eclipse of the century, lasting 1 hour and 43 minutes, nearly 40 minutes longer than the super-blue moon combination on January 31.

At 3:30 a.m. Beijing time on July 28, the longest total lunar eclipse of the 21st century will occur, when the moon will be covered in a magnificent layer of crimson. At night, one can also see "Mars rushing towards the Sun" (the Earth is located between Mars and the Sun, with three celestial bodies in a line). This "opposition" is the closest Mars has been to Earth in 15 years.

The total lunar eclipse will start at 2:24, the eclipse will start at 3:30, the eclipse will start at 4:22, the eclipse will start at 5:14, and the last contact will be at 6:19. Top marks for gastronomy.

The total lunar eclipse will last 104 minutes (from eclipse to light), making it the longest total lunar eclipse in 18 years. In nearly 300 years (from the 19th century to the 21st century), the longest total lunar eclipse occurred on July 16, 2000, lasting 107 minutes (from eclipse to light), 3 minutes longer than this total lunar eclipse, and the maximum total lunar eclipse was reached.

If this total lunar eclipse is missed, China will not see the next one until May 26, 2021.

According to the lunar eclipse map released by NASA, people in most parts of the planet except North America can see a total or partial lunar eclipse. In China, the westernmost region can observe the complete process of the total lunar eclipse, and most areas can see the "lunar eclipse moon", which is a round of "blood moon" in the night sky.

July 28 will usher in the longest total lunar eclipse of the century, visible to the naked eye.

When a total lunar eclipse occurs, the Moon, the Earth, and the Sun are completely in a straight line, with the Earth in the middle, and the entire Moon enters the Earth's umbra, and as the Earth's shadow deepens on the Moon's surface, it will turn dark red, and this intensity depends on the disturbance of the atmosphere. Having a moon means there are more visible stars, and during a total lunar eclipse, if the sky is clear, we can even see the Milky Way itself appear as a hazy white galaxy that stretches out in a curved arc.

It is completely safe to have a total lunar eclipse with the naked eye, although if there are conditions to use binoculars or a powerful telescope, this experience will be greatly enhanced.

The long duration of a total lunar eclipse can provide enough time for amateurs to try and capture the picture. The most valuable aspect of this event is that it can greatly stimulate the curiosity and desire of young people.

If the sun, earth, and moon happen to be in a straight line, and all or part of the moon revolving around the earth enters the earth's shadow, people in the earth's night hemisphere can see the moon's shape and color change, which is called a lunar eclipse. It has some observation value.

Total lunar eclipse (total lunar eclipse), an astronomical term, is a kind of lunar eclipse, when the moon, the earth, and the sun are completely in a straight line, the earth is in the middle, and the entire moon enters the shadow of the earth, and the surface of the moon turns dark red, forming a total lunar eclipse. This total lunar eclipse occurred during the daytime in China, and the public could not catch a glimpse of the "red moon". Astronomical science experts said that on November 8, the second total lunar eclipse of the year will be more observable for the Chinese public.

The main reason why a total solar eclipse is so much appreciated is that it is of great astronomical value, because the moon will dim the originally dazzling sun and reveal the coronal layer that is not easy to observe. There are many great astronomical and physical discoveries in the history of science that have been made by taking advantage of total solar eclipses, and only by doing so. The most famous example is a total solar eclipse in 1919, which confirmed the correctness of Einstein's general theory of relativity.

In 1915, Albert Einstein published what at the time seemed extremely difficult and implausible to understand and implausible, a theory that predicted that light would bend in a huge gravitational field. The strongest gravitational field that humans can access is the sun, but the sun itself emits a strong light, and it is impossible to see whether the faint star jujube bond light in the distance turns when it passes near the sun.

The total solar eclipse is a strange and rare natural spectacle, and it is also a good opportunity for people to learn about the sun. Observation and research of geophysical effects during total solar eclipses is of great scientific value.
