The supernova of 1054 was first observed on July 4, 1054. It was recorded by Chinese and Korean astronomers, and there is evidence suggesting it may have also been observed by southwestern American Indians, as indicated by rock paintings found in Arizona and New Mexico.12
The event occurred in the constellation Taurus, appearing in one of the constellation's horns. The explosion was remarkably bright, remaining visible during the day for 23 days and visible at night for nearly two years. The remnant of this historic event is known today as the Crab Nebula.21
