"In the second year of the Zhongping reign period, in the 10th month, on a Guihuai day, a 'guest star' emerged within the Southern Gate," says an ancient Chinese journal of record, referring to an awesome celestial event that occurred on December 7, 185 AD.
"It ...(had) scintillating, variegated colours, and it then grew smaller, until in the sixth month of the hou-year [July 5 to August 2, 186 AD] it disappeared."
The "guest star" so vividly portrayed almost 2,000 years ago in the Astrological Annals of the Houhanshu has now been confirmed as the world's oldest recorded supernova.
