Which of the following accurately describes the M1 Nebula?

The M1 Nebula, also known as the Crab Nebula, is accurately described as a supernova remnant and pulsar wind nebula. This classification stems from its origin as the result of a supernova explosion that was observed in the year 1054 AD.

After the star exploded, the remaining material from the explosion expanded outward, creating a glowing cloud of gas and dust that we now observe as the Crab Nebula. The nebula is notable for containing a pulsar at its center, which is a highly magnetized, rotating neutron star. This pulsar emits beams of electromagnetic radiation out of its magnetic poles, which we detect as pulses as the beam sweeps across our line of sight, hence the term "pulsar wind."

The classification as a pulsar wind nebula is significant because it highlights the interaction between the energetic output of the pulsar and the surrounding material from the supernova. The pulsar's intense wind creates complex structures within the nebula, including the filaments we can observe today.

In contrast, a Type II supernova remnant mainly refers to remnants from stars that had high mass and ended their life cycle in a specific manner. While M1 does indeed originate from a supernova, the
