Behold: Messier 1 – the inextricable mess left over when a star explodes. To wit:

The Crab Nebula – the result of a supernova seen in 1054 AD – is filled with mysterious filaments. The filaments are not only tremendously complex, but appear to have less mass than expelled in the original supernova and a higher speed than expected from a free explosion. The featured image, taken by the Hubble Space Telescope, is presented in three colours chosen for scientific interest. The Crab Nebula spans about 10 light-years. In the nebula‘s very centre lies a pulsar: a neutron star as massive as the Sun but with only the size of a small town. The Crab Pulsar rotates about 30 times each second.
