The Crab Nebula is the remains of a supernova that was observed in 1054.
It is the stellar remnants of a star that exploded thousands of years ago.
I've not heard of it being referred to as a "stellar graveyard" but I guess it is because of the death of the host star.
"The Crab" is a nebula.
The crab nebula.
The Crab Nebula or SN1054 is still visible with telescopes.
The crab nebula is the debris formed in the supernova explosion.
Yes, it's called the crab pulsar.See related link for more information
The Crab Nebula is a supernova remnant and pulsar wind nebula.
The Crab Nebula was formed when it's host star exploded as a supernova [See related question]
It was first observed by Chinese astronomers in 1054 AD, but given it's (estimated) distance from earth of 3,600 light years, the actual explosion would have taken place 3,600 years earlier, or around 2,500 BC.
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.
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!
The Crab Nebula was first observed in 1731.
