687 Words2 Pages

When looking at the history of astronomy, many will often first think of the ancient Greeks and later on the men of the Age of Enlightenment and their discoveries. However documents from ancient China show that they were observing and recording celestial movements long before the Greeks.
As tradition dictated that the rulers of China should receive their political mandate from the sky, astronomy soon became a dominant science in China. The main responsibility of political power was to keep the Earth in total harmony with the sky. This obligation was called the “Mandate of Heaven.” The stars were bestowed with astrological meaning, both enabling predictions that influenced daily life as well as major political strategies, and thus astronomy …show more content…

As early as 2254 BCE, the Records of the Grand Historian, or Shi Ji, and the Book of Ancient Time, or Shang Shu, provide writings that state how Emperor Yao got astronomers to calculate solstices and predict seasonal changes to assist farmers, as well as his advisors. He assigned officers to observe patterns such as the sun rising and setting, and the appearance of stars at night. This allowed a solar and lunar calendar with 366 days to be created (Astronomy in Early Chinese Sources). The Book of Documents also dated four asterisms to the 21st century BCE. Stars and their movements were being recorded during the Shang dynasty in 1500 BCE, and oracle bone writings from 1400–1200 BCE indicate that the Yin used a year of 12 lunar months, each of 29 or 30 days, with an extra month every three years. Records and star catalogues of astonishing detail were kept from 600 BC onwards (Sarma). Then in recent years, archaeological work done at Taosi, an ancient site in Shanxi, shows the possibility of an early observatory being built to aid astronomical officers dating back to 2100 BCE–1600 BCE (Pankenier, Liu and Des …show more content…

Ancient Chinese astronomers poetically named these explosions ‘guest stars’ and a full catalog of them. This catalog was maintained over centuries and carefully noted their various appearances and offers accurate information about their positions which has enabled modern astronomers to find remnants of these explosions in the sky today (International Dunhuang Project). Throughout the years, the Chinese also developed three different cosmological models. The first model was the Gai Tian. This model was a hemispherical dome that conceived the heavens as a hemisphere lying over the Earth, which was dome-shaped. The second model saw the heavens as a celestial sphere. Then finally the third model viewed the heavens as floating about in rare intervals (Needham and
