The Crab Nebula is a supernova remnant and pulsar wind nebula in the constellation of Taurus. Located at a distance of about 6,500 light-years from Earth, the nebula has a diameter of 11 ly and is expanding at a rate of about 1,500 kilometers per second. 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.
