Description:
A dazzling star, SN 1006.
This may be the brightest supernova explosion in recorded human history; in 1006 AD, its light illuminated the entire Earth’s sky. Discovered in the southern constellation of Lupus, the expanding cloud of debris from the stellar explosion is still visible across the electromagnetic spectrum. This nova is approximately 7,000 light-years from Earth, meaning the explosion occurred about 8,000 years ago, and the light from the explosion reached Earth in 1006.
