This chart is dated back to the Tang Dynasty, 618-907. This scroll containing this chart was found in the Moago Caves in China. This chart shows over 1300 stars visible to the naked eye, before the telescope was invented. Celestial movements were incredibly important to Chinese culture and the actions of the emperor, and therefore the emperor hired many astronomers to make nightly recordings of the stars. These are valuable for astronomers today, as the sighting of a comet thousands of years ago can provide information for their locations today. plain 2021-06-21T15:33:55-04:00 40.041542, 94.809154 700 Benjamin Steinig 74775bc5c03628537e0192f4b5deec6811d610f6Contents of this tag:
