The story of the confrontation was embellished afterward as pro-Russian propaganda of liberation.

Oct. 9, 1604: Kepler’s Nova (SN 1604), the most recent supernova explosion in the Milky Way, is first observed in the constellation Ophiuchus.

SN 1604 became visible to the naked eye in Oct. of 1604. Its appearance was recorded all over the world. Believing it to be a star, German astronomer Johannes Kepler studied the phenomenon until it faded from sight to the naked eye in 1606. Modern scientists have studied the remnants and identified it as a Type Ia supernova, which are supernovae that occur in binary systems containing a white dwarf. It is the last recorded supernova witnessed within the Milky Way galaxy and was described in detail by Kepler in his book “De Stella Nova,” published in 1606. 

Oct. 10, 1911: The 1911 Revolution began in China.
The Qing Dynasty was the last dynasty of China, coming to an end as a result of the Republican Rebellion, also known as the Xinhai Revolution. The Qing Dynasty was officially overthrown on Feb. 12, 1912, when the boy emperor Xuantong, also known as Puyi, was forced to abdicate. The revolution was brought about after a series of Chinese defeats from the first Opium War (1838-42), the Anglo-French War (1856-58), the Sino-Japanese War (1894-95) and the Boxer Rebellion of 1900. The Qing Dynasty lasted for almost three centuries, from 1644 to 1911. Following his abdication, a provisional republican government came into being under Yuan Shikai, who served as the provisional President of the Republic of China from 1912 until he died in 1916 at age 56.
