What was discovered

The physician and astronomer described a new star in Lupus, three times larger than Venus and a quarter as bright as the Moon. It is the most detailed account of the brightest supernova ever recorded.

It was also recorded by Chinese, Japanese, Iraqi and Yemeni astronomers and by the monastery of Saint Gall.

What it led to

  • identification of the SN 1006 remnant
  • studies of Type Ia supernovae
  • astronomical chronology cross-checked with Chinese and European records
