Ancient star chart

A star map is a map that records the positions of stars in the sky. For the convenience of memory, people connect the stars in a star chart to form a certain pattern, which is called a constellation. The development of star charts records the process of human observation of the sky. In star charts, the most familiar constellation to us is the ecliptic constellation. At the beginning of the 20th century, the International Astronomical Union identified 13 zodiac constellations, including Ophiuchus and 12 constellations corresponding to birthdays. Let's embark on this astronomical journey from the star chart and the zodiac signs.

The ancient star chart is an astronomical chart used to depict the positions and relative relationships of stars and other celestial bodies in the sky. The depiction of star maps by humans has existed since ancient times, and the mural painted in front of the Lascaux Cave 15000 years ago is the earliest depiction of stars by humans; More than 3000 years ago, the Sumerians drew the first star chart in history, providing a systematic depiction of the starry sky and using pictures to depict specific parts of the sky for ease of memory. This method was passed down to Greece and further developed into ancient Greek constellations, with the entire Western star chart being an extension of the representation of ancient Greece. Coincidentally, ancient Chinese people also used a similar star system to divide the sky. The Dunhuang star map is the most comprehensive map of the entire Northern Hemisphere sky. With the rise of the Age of Discovery, astronomers discovered new constellations in the southern hemisphere, and the completion of the Southern constellations also led to the creation of a true map of the night sky on Earth. In 1924, the first meeting of the Astronomical Society established 88 constellations.
