The crab nebula is estimated to be about 6,300 light year away.
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.
The Crab Nebula was first observed in 1731.
The Crab Nebula's longitude is 184.6 and its latitude is -5.80, in the third galactic quadrant.

The Crab Nebula is within the Milky Way galaxy, but about 2000 parsecs away from Earth, or about 6300 light years. It is still expanding from the initial supernova (observed in 1054 AD) and is currently about 11 light-years in diameter.
The Crab Nebula is too far away for its energy to have any impact on Earth.

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!
