"SN 1054 (Crab Supernova) was a supernova that was widely seen on Earth in the year 1054. It was recorded by Korean, Chinese, Japanese, Native Americans, and Persian/Arab astronomers as being bright enough to see in daylight for 23 days and was visible in the night sky for 653 days. The progenitor star was located in the Milky Way galaxy at a distance of 6,300 light years and exploded as a core-collapse supernova."

"The cloudy remnants of SN 1054 are now known as the Crab Nebula."
