The Crab Nebula is a supernova remnant in the constellation of Taurus. Corresponding to a bright supernova recorded by Chinese astronomers in 1054, the nebula was observed later by English astronomer John Bevis in 1731. The nebula was the first astronomical object identified with a historical supernova explosion.

 

The nebula lies in the Perseus Arm of the Milky Way, at a distance of about 6,500 light-years from Earth. It has a diameter of 11 light-years, corresponding to an apparent diameter of some 7 arcminutes, and is expanding at a rate of about 1,500 km/sec.

 

At the center of the nebula lies the Crab Pulsar, a neutron star 28–30 km across with a spin rate of 30.2 times per second, which emits pulses of radiation from gamma rays to radio waves. At X-ray and gamma ray energies above 30 keV, the Crab Nebula is generally the brightest persistent source in the sky
