Do you know the origin of constellations?

Simply put, it is to connect the stars in the sky one by one, and then connect them with familiar patterns. For example, Scorpio has a bright star line shaped like a giant scorpion. 88 internationally recognized constellation names have covered the whole sky, so there will be no new constellation names in the sky. Constellation means that stars can form an imaginary outline or pattern on the celestial sphere (in short, the pattern formed by connecting stars). These patterns usually include animals, plants, mythical figures, gods or inanimate objects. In ancient times, due to the limitation of science and technology, the ancients could only draw the patterns of stars in the sky by their own imagination.

The origin of the word "constellation" may be traced back to prehistoric times. At that time, the ancients only used them to tell their own beliefs, experiences, creations or some fairy tales. Different cultures and countries adopted different constellations. Some constellations were named until the early 20th century, and these constellations were not recognized by the whole world until modern times (International Astronomical Union 1930). ? With the passage of time, the adoption of constellations has changed greatly, and the size or shape of many constellations has changed greatly, which may be caused by precession (axial precession of the earth).

Among these constellations, 48 traditional western constellations were named during the Greek period, so they are also called Greek constellations. ? These Greek constellations often appear in Aratus's images and Ptolemy's astronomical masterpieces, but the origin of Greek constellations may be centuries earlier than these works. From15th century to18th century, European explorers began to observe in the southern hemisphere, so the constellations in the southern hemisphere were increasing. The most striking thing is the oldest constellation in the zodiac (crossing the ecliptic, that is, the ecliptic through which the sun, moon and planets pass). However, the origin of the zodiac is still a mystery in history; ? In 400 BC, its astrological division was particularly prominent in Babylonian or Chaldean astronomy, but its origin can probably be traced back to prehistoric times.
