The first recorded observations of solar eclipses and supernovae were made in China.[28] On July 4, 1054, Chinese astronomers observed a guest star, the supernova now called the Crab Nebula.[28] Korean contributions include similar records of meteor showers and eclipses, particularly from 1500-1750 in the Annals of the Joseon Dynasty. Traditional Chinese Medicine, acupuncture and herbal medicine were also practised, with similar medicine practised in Korea.
