Today's horoscopes and horoscopes before 2000

First of all, we must find out what the solar system and constellations are.

The celestial bodies in the universe are constantly moving, forming celestial bodies systems at all levels. For example, the moon revolves around the earth to form the earth-moon system, and the earth is the central celestial body in earth-moon system. The earth and other planets in the solar system revolve around the sun, which is the central celestial body in the solar system. The solar system is a small part of the Milky Way. In the Milky Way, there are over 200 billion stars like the sun.

Outside the Milky Way, there are about 654.38+billion celestial systems similar to the Milky Way, which we call extragalactic galaxies. The Milky Way and the extragalactic galaxy * * * together constitute the main galaxy. The total galaxy is the part of the universe that people can observe at present.

In order to understand the starry sky, people imagine the universe as a sphere with infinite radius, called the celestial sphere.

In order to understand the stars, people divide the celestial sphere into several regions, which are called constellations. For example, the Big Dipper is the main part of the constellation Ursa major. According to international regulations, the world is divided into 88 constellations. Every star belongs to a constellation. For example, Polaris is a star in Ursa minor.

Therefore, the solar system and constellation are completely different concepts and cannot be confused.

The origin of 12 constellation and 88 constellation

Constellation 88: In ancient times, people connected the scattered stars in the sky through imagination in order to facilitate navigation and observe the astronomical phenomena. Half of them were named in ancient times, and the naming method was based on the myths and forms of ancient civilizations (including the myths and epics of Mesopotamia, Babylon, Egypt and Greece). The other half (mostly in the night sky in the southern hemisphere) was named only in modern times, and is often named after navigation instruments. In ancient times, because of different regions, the way of "Lianliankan" was different! Now the world has unified the constellation map into 88 constellations and divided the sky into 88 regions.

12 constellation: what we usually call "constellation" refers to "sun constellation"; That is to say, people on the earth are the center, and at the same time, we can see which constellation the sun is in orbit (Greek zodiac: meaning ~ circle made by animals, also known as "zodiac"), so we can say what constellation that person is. More than 2000 years ago, the Greek astronomer Hipparchus (190 ~ 120 BC) divided the ecliptic into twelve segments, with spring divided into zero, and every 30 degrees from the vernal equinox (that is, the zero degree of the ecliptic) as a palace, taking the main constellations contained in each palace at that time. There are twelve constellations in all. Babies born when the earth moves to every fraction (constellation) will always have some similar characteristics when they grow up, including behavioral characteristics. By connecting these associations (rich imagination and creativity) in series, these constellations are visualized; It also adds the color of myth and becomes an important part of culture (mainly Greek and Roman mythology). This set of numerology has been developed and circulated for at least five thousand years, represented by these twelve constellations respectively. But these constellations do not represent a certain "star", but can only be regarded as "representative symbols of the same name".

A little information about 12 constellation:

1. Sun (Sun)

A circle symbolizing the spirit, with a dot in it, represents the bud of life in chaos.

● The sun guards Leo; The meaning of personal birth chart is self-expression. As the source of all the stars, it affects personality. Looking at Leo from the sun, we can find its love and photometric characteristics; In addition, the sun is often compared to an emperor, which is also related to Leo's love of face and the wind of kings.

Does this mean that the sun belongs to Leo in 12 constellation? -American police)

A little information about 88 constellations:

Andromeda

Andromeda has already mentioned it when talking about the autumn quadrangle (see the constellation introduction of Pegasus). The alpha star that constitutes this quadrilateral is the brightest star in Andromeda, which extends northeast from the diagonal line from Alpha Pegasus to Alpha Andromeda in the quadrilateral, and the three bright stars of Andromeda (except for the delta of 3m, the other two are 2m stars) are almost all on this extension line. Further on, you will meet the great spirit of Perseus. Daling V, Perseus α and Andromeda γ form a right triangle.

This Andromeda gamma star is a binary star, in which the main star is an orange star with a length of 2.3m and the companion star is a yellow star with a length of 5.1m.. Interestingly, this companion star is a "chameleon", which changes from yellow and gold to orange and blue, just like a clever magician.

Andromeda's most famous celestial body is probably the Big Nebula. Near Andromeda υ, on a clear moonless night, we can see a small blue and white cloud, which is the Andromeda Nebula. This nebula was discovered by astronomers as early as 16 12, but it was not until the 1920s that American astronomer Hubble made it clear that it was completely different from the nebula in Sagittarius. It is a large galaxy 2.2 million light years away from us, so its correct name should be "Andromeda Extragalactic Galaxy".

Andromeda, an extragalactic galaxy, has a diameter of 65.438+0.7 billion light years and contains more than 300 billion stars. Much like our Milky Way, it is also a vortex, and there are also many variable stars, clusters and nebulae. Interestingly, there are two small galaxies nearby, which together form a triple galaxy.

Le Signe du Lion

Once I mentioned Leo when I introduced Capricorn and Virgo in the spring night sky. The constellations of beta star in Leo, arcturus in Capricorn and Virgo form an important "Spring Triangle" in spring night.

Leo is also the zodiac sign. Due to precession, the apparent motion of the sun just passed Leo in June every year more than 4,000 years ago. It's June, and the obvious movement of the sun has reached between Taurus and Gemini. At that time, people in the ancient Persian Gulf country of Chaldea thought that the sun got a lot of heat from Leo, so the weather became hot. The ancient Egyptians felt the same way, because at this time of year, many lions moved to the Nile Valley for the summer.

Ancient Egypt worshipped Leo very much. It is said that the famous Sphinx is shaped by the body of a lion and the head of a maid. The star of Leo was also highly valued in ancient China, and was called the God of the Yellow Emperor and Xuanyuan.

After we found the beta star of Leo through the spring triangle on a spring night, a big star to its east was all Leo's. In Leo, delta, theta and beta stars form a remarkable triangle, which is the lion's back and tail. These six stars from ε to α form the shape of a sickle, which is also like a reverse question mark. This is the lion's head. When the Polaris connecting the constellation Ursa major (that is, the two stars in the spoon mouth) extends in the opposite direction to Polaris, you can find it. Alpha star is called Xuanyuan XIV in China, and its apparent magnitude is1.35m. It is the brightest star in Leo, and it is the 2nd1in the whole day. It forms an isosceles triangle with arcturus and arcturus, and can be found by extending the δ and γ stars of Ursa Major ten times. In ancient times, navigators often used it to determine the position of ships in the sea, so Alpha Leo was awarded the title of "one of the nine navigation planets".

Leo's Xuanyuan XIV is located near the ecliptic, which is about 90 degrees away from the four bright stars Taurus, Scorpio Antares and Nanyu's Beiluoshimen. They are called the "four heavenly kings" of the zodiac.

Every year in June165438+1mid-October, especially in the nights of June 14 and June 15, a large number of meteors will appear near ζ star with question marks written on Leo. This is the famous Leonid meteor shower. It peaks every 33 years. As early as 93 1 year, it was recorded in China in the Five Dynasties. At the peak of 1833, meteors exploded near zeta star like fireworks, with tens of thousands of them every hour. Therefore, the next night, a farmer hurried outside to see if all the stars in the sky had fallen out. Can you explain that the sun belongs to Leo? -American police)
