The Crab Nebula, also designed as M1 or NGC1952, is a supernova remnant and pulsar wind nebula in the constellation of Taurus and is located at a distance of about 6500 light-years from the Earth and has a diameter of 11 light years but expands at a rate of about 1500 kilometers per second.. The bright supernova that formed it was recorded by Chinese and Arab astronomers in 1054.
At the center of the nebula lies the Crab Pulsar, a rotating neutron star, which emits pulses of radiation from gamma rays to radio waves with a spin rate of 30.2 times per second. The nebula was the first astronomical object identified with a historical supernova explosion.
