Nebula in the constellation of Taurus.
The Crab Nebula is a supernova remnant of plerion type (is a nebula powered by the pulsar wind of a pulsar). At the center of the nebula lies a pulsar with a spin rate of 30.2 times per second which emits pulses of radiation from gamma rays to radio waves. The nebula lies in the Perseus Arm of the Milky Way galaxy. It is located at a distance of about 1930 parsec (6300 light years) from Earth, it has a diameter of 3.4 parsec (11 light years) and it is expanding at a rate of about 1,500 km/s. The discovery of the nebula was the first evidence to show that supernova explosions produce pulsars.
