Filaments
Nebulae #3. After the Crab Nebula, the supernova of 1054. An expanding shell pushes light gas against dense gas and the boundary breaks into fingers (a Rayleigh-Taylor instability): domain-warped noise is sampled in coordinates stretched along the rays, and the veins of the field become filaments, carried outward by the expansion. Inside, the blue haze of the pulsar wind; at the centre, the pulsar sends out wisps.
