How did the supernova of 1054 form the Crab Nebula?

The Crab Nebula was formed by the cataclysmic explosion of a massive star, an event observed by astronomers in 1054. During this supernova, the star ejected a significant portion of its mass into space, creating a violently expanding cloud of debris.123

This remnant is composed of glowing gas filaments—the ejected material—that continue to expand outward. At the center of this nebula lies the Crab pulsar, a rapidly spinning neutron star that serves as the collapsed core of the original star. This pulsar provides the energy necessary for the nebula to glow by losing its own rotational energy, which powers the emission of radiation across the electromagnetic spectrum, including the characteristic synchrotron radiation observed in the nebula's inner region.213
