SN 1006: The Brightest Supernova Ever Witnessed
TravelIn the spring of 1006, people across Asia and Europe looked up into the night sky and saw something astonishing: a brilliant new star blazing in the southern heavens. It appeared suddenly, shone with extraordinary intensity for months, and then slowly faded away. Today astronomers know this object as SN 1006, the brightest stellar explosion ever recorded in human history.
Modern estimates suggest the supernova reached a visual magnitude of about −7.5, making it far brighter than Venus and possibly bright enough to be seen during daylight. Yet as bright as it appeared in the 11th century, the remains of the supernova are all but invisible today.
