... I'm going to do a Neufer and talk about something else. Although admittedly he would talk about Shakespeare or Finnegan's Wake, not about cosmic vistas that have nothing to do with the APOD in question. But I'm me, so I'll do precisely that.

The Crab Nebula supernova remnant is famous for its synchrotron radiation:

Central part of the Crab Nebula. The neutron star is the one farthest to the right of the two bright stars near the center. The thick red strands are ionized hydrogen (along with other ionized elements), while the ghostly glow is synchrotron radiation. Credit: ESA/Hubble & NASA. Acknowledgement: Mahdi Zamani.
