SN 1054 was a supernova that was widely seen on Earth in the year 1054. It was recorded by Chinese and Arab astronomers as being bright enough to see in daylight for 23 days and was visible in the night sky for 653 days. It was likely a Type II supernova.

The cloudy remnants of SN 1054 are now known as the Crab Nebula, also referred to as M1; being the first Messier Object catalogued in 1774. X-rays from this object were detected in April 1963 with a high-altitude rocket of type Aerobee with an X-ray detector developed at the Naval Research Laboratory; the X-ray source was named Taurus X-1, and the energy emitted in X-rays by the Crab nebula is about 100 times more than that emitted in the visual light.
