This is a crop from a much larger image of the famous Vela SNR. This is a region that I love to view full screen and ponder each wispy filament. What an astounding blast it must have been about 12,000 years ago when a massive star collapsed then exploded creating both the Vela Supernova Remnant nebula and the Vela Pulsar. In fact, the association of this SRN with the Pulsar served as evidence that neutron stars (including pulsars) result from supernovae.

But what if this isn’t an SNR at all? A 2016 paper provides evidence that the Vela SNR, along with many other SNRs including M1, the Crab Nebula, do not meet the criteria of supernova remnant. http://simbad.u-strasbg.fr/simbad/sim-ref?bibcode=2016ApJS..224....8A It’s reminiscent of declassifying Pluto as a planet, except in this case it is more like saying the Earth and Jupiter aren’t planets. It seems that no one has known what to do with this information, and all databases still refer to these objects as SNRs. It will be interesting to see how this plays out; but just as a rose is a rose, the Vela SNR remains just as amazing no mater how it is classified.
