How much do you know about astronomy? There were many great developments, inventions, and astronomers who have helped us to learn more about the stars and skies. One famous example is the astronomer Nicolaus Copernicus who helped to formulate the heliocentric model of the universe. In other words, Copernicus was the first person to create a model that proposed that the Sun, and not the Earth, was the center of the Solar System.
Did you know that Koreans also had many scientific developments in the field of astronomy? It all started during the Joseon Dynasty (1392-1910) . During this period, remarkable scientific developments were achieved and many astronomical instruments were created. Later on, an astronomical calendar system called Chilijeongsan was also created in 1444.King Sejong was also able to create the Korean native alphabet, Hangeul, and the native time system during this time.
This was all made possible because of the remarkable scientists who supported King Sejong’s vision. These scientists, like Jeong Inji, Jeong Cho, Yi Cheon, and more were actually named after a few asteroids by the International Astronomical Union in 2004 which were discovered by modern Korean scientists.
King Sejong and these scientists were able to make remarkable contributions towards history.
