The Crab Nebula is a remnant of a supernova located in the constellation Taurus. Historical records have revealed that both Chinese and Arab astronomers noted this supernova in 1054 A.D. The supernova was so bright that it would have been visible to the naked eye in the daylight for nearly 2 years. The result of this supernova is the beautiful Crab Nebula that we see today. The blast has emitted various heavy elements that have scattered across space. At the center of the nebula lies the Crab Pulsar a rotating neuron star which emits pulses of radiation. The Crab Nebula continues to expand to this day.
