Most of the modern constellations evolved from the traditional constellations of ancient Greece, and the International Astronomical Union accurately divided the whole day into 88 constellations.
West: Originated in ancient Babylon, one of the four ancient civilizations.
China: Divide the sky into three walls and twenty-eight nights.
Modern constellations: In 1928, the International Astronomical Union officially announced the international scheme of 88 constellations. At the same time, it was stipulated that the vernal equinox and the equator of 1875 should be used as the benchmark.
According to the different positions of the 88 constellations on the celestial sphere and the inhabitation of stars, they are divided into five regions, namely, the North Celestial Arch Constellation (5), the Northern Celestial Constellation (40 90°, 19), the Zodiac Constellation (12 constellations near the ecliptic on the celestial sphere), the Equatorial Constellation (10), and the Southern Celestial Constellation (-30 -90°, 42).
The 12 zodiac signs that we usually refer to as birthdays are the twelve regions of the zodiac that astrology describes the sun passing through the ecliptic on the celestial sphere. The original meaning should be to divide the date, similar to synodic hope. The definition of the zodiac in astrology refers only to the twelve equally divided regions of the zodiac, which is different from the astronomical zodiac.
After the International Astronomical Union standardized the constellation boundaries in 1928, there were 13 constellations in the zodiac (including Ophiuchus).

Analysis: A constellation is a combination of stars in the sky. In the three-dimensional universe, these stars have no actual relationship with each other, except that they are located in close proximity to each other on the plane of the sky.
Since ancient times, people have been very sensitive to arrangement and shape, so it is natural to associate some stars with similar positions to form constellations.
Constellations occupy an important place in astronomy; Astrology also makes use of the concept of constellations, but many astronomers see astrology as a pseudoscience that does not really use the scientific method.
Basically, the formation of stars into constellations is a random process, and there are different constellations of different stars in different civilizations - although the composition of some of the more prominent stars will be roughly the same in different civilizations, such as Orion and Scorpio.
The International Astronomical Union divides the entire sky into eighty-eight official constellations with precise boundaries, so that each direction of the sky belongs to a specific constellation. Most of these official horoscopes are based on the traditional horoscopes of ancient Greece that have been handed down from the Middle Ages.

The conditions for the formation of fog are cooling and humidification, which increases the water vapor content. This is formed by radiative cooling, which mostly occurs at night and early in the morning when it is clear, breezy, and the water vapor near the surface is relatively abundant and stable, or there is a temperature inversion, which is called radiation fog in meteorology; the other is the fog formed by the horizontal movement of warm and humid air, passing through the cold ground or water surface, and gradually cooling, which is called advection fog in meteorology; Sometimes fog formed by both causes is called mixed fog. It can be seen that those who have these conditions are in late autumn and early winter, especially in the morning of late autumn and early winter. >>>More
