Well, darling, a nebula is a big ol' cloud of dust and gas in space, while the Crab Nebula is a specific nebula located in the constellation Taurus. So basically, it's like saying a nebula is a generic term for a cloud in space, while the Crab Nebula is a specific cloud that got its own fancy name. Hope that clears things up for ya, sugar!
Crab Nebula:Pulsar wind nebulaSupernova remnantRadius of 5.5 ly6,500 light years awayOrion Nebula:Diffuse nebulaStellar nurseryRadius of 12 ly1,244 light years awayEdit: M1, the Crab Nebula, is related to the death of a star. The Orion Nebula, M42, is relateted to the birth of stars.
Pulsars were discovered in the Crab Nebula, a supernova remnant, in 1967. The Crab Pulsar is a neutron star at the center of the nebula that emits beams of radiation, producing regular pulses of light. The high-energy particles and magnetic fields in the nebula power the pulsar's emission.
