In ancient Korea planetary alignments were considered a blessing from the sky and were recorded in writings, such as can be seen in the book 'Hwandangogi'. This is a compilation of texts written during the ancient times of Korea going back 9000 years. Modern day Korean astronomers proved that the alignment of the planets that occurred in BC 1733, as recorded in the book 'Hwandangogi', actually did happen, validating the credibility of the book. We explore further into this book of K-history including the portion that recites the Dangun Chosun period that lasted from BC 2333 to BC 238.
